What are façade repairs?
Repairing the facade of a house is a whole range of work to assess the level of damage and defects, prepare surfaces, reconstruct engineering structures and coatings. There are two types of repairs :
The last option involves partial restoration of the appearance of the building without making changes to the hydro- and thermal insulation system: buildings whose facades face the road darken over time due to vehicle exhaust gases, fade in the sun and are damaged by gusts of wind.
During a major overhaul, at least a third of the entire façade is destroyed. Such work is used when changing the purpose profile of a building, constructing extensions and redevelopment. At the same time, old coatings are removed and a full range of installation, preparatory and repair activities are carried out.
Sanitary rules and regulations determine that current (decorative) repairs of house facades must be carried out at least once every five years, and major repairs at least once every ten years.
How to properly finish facades.
Construction and related technologies are aimed at improving the aesthetics of those objects that need to be rebuilt, as well as to increase their service life. The last aspect is sometimes more important than the first. The environmental friendliness of materials, as well as savings in their acquisition, are also very important! It doesn’t matter what we are talking about - some individual components or an entire structure that is almost ready for use. Every aspect plays an important role and nothing should be forgotten.
On the one hand, facades with a filtration system are a reasonable stage in technology, as they are characterized by the competent completion of any task related to finishing. A very convenient and profitable way. Take, for example, the fact that the use of this type of facade allows you to design them almost any way you want, which is very important if we are talking about any new object. For older buildings this is also important, especially if it is to be renovated and ultimately needs to blend in with its surroundings.
Also, this design is not afraid of almost any external factors (sudden temperature changes, precipitation in the form of rain, snow or hail). Technology makes it possible to use a variety of materials for construction, be it tiles, stone or anything else. It can be used anywhere depending on the need. Today, it is popular to use these facades in industrial buildings, as well as in commercial and administrative facilities.
Service life when finishing facades - what should be taken into account first?
With the above aspects, remember that the service life and related parameters also increase. For example, heat loss becomes lower, and fungus and mold will only bother you in rare cases. The structure will not be destroyed under any circumstances. This means that the cost of maintaining the building will be significantly reduced. This includes heating and necessary repairs. The structure will be used for a long time. The savings when using technology are obvious, so there should be no doubt about whether to use it or not.
Depending on how complex the upcoming project is and what materials were used for manufacturing, facades can have very different price categories. However, using tiles will cost much less than special stones for facades. But now designers are ready to offer almost any solution that would be beneficial for everyone, including the customer’s pocket. Whatever the costs, the cost-effectiveness of the material and long service life will ultimately pay off all costs, perhaps even several times more.
What material to choose for finishing?
Typically, the search for materials begins with determining how much to meet. Unfortunately, not everyone can afford expensive materials and included components. However, remember that if you skimp, you risk paying twice. Select the facade wisely, paying attention to the combination of one material with another - for example, a load-bearing wall and insulation. Remember about the declared service life, the possibility of corrosion and other qualities. If you have any doubts or questions, it is advisable to contact specialists and consultants. There is always an option that can suit the customer.
Silicone plaster is the most suitable material for finishing facades. The only drawback of this material is its high cost. However, if you have the funds, there is no reason to refuse such a convenient option. Silicone plaster lasts for decades and can withstand almost any conditions, while being suitable for any type of facade with thermal insulation.
Where can you buy artificial stone at a lower price? For designers, this material opens up more possibilities. At the same time, it is almost no different from natural stone. The material is almost perfect. There are granites, marble, sandstone, shell rock, and many other samples to choose from.
The main advantages of technology for finishing facades.
The most important of all the advantages of the technology available and listed above can be safely called convenient installation, regardless of the season and weather conditions at the moment when the installation takes place. This not only makes the work faster, but also allows you not to lose quality during the installation process. Having studied everything stated above, now you probably no longer doubt why such facade systems are so popular at the present time. A modern and convenient method of finishing facades will ensure efficient use and long service life of certain objects.

Repairing a porcelain stoneware system
Porcelain stoneware tiles are a high-quality cladding material that is characterized by minimal hygroscopicity and is made from several types of clay with the addition of natural minerals and dye. The repair of such a facade is addressed in two cases:
- If the slabs are damaged due to external influences: falling branches, resulting in an accident, etc.
- If the façade system is installed incorrectly.
In the first situation, damaged elements are replaced with new ones, in the second, the facade is dismantled, violations of the installation technology are identified and eliminated.
Features of repair of plastered surfaces
Plaster is an affordable and very versatile building material, which is often used for cladding facades. The advantages of this mixture are its low weight, wide selection of colors and ease of use. When restoring the plaster layer, you need to pay attention to the following points:
- It is prohibited to apply gypsum mortar to a concrete base;
- the layer of plaster should be no thicker than three centimeters;
- Grouting should be done four to five hours after applying the plaster.
If the total area of destruction of the finishing made from the plaster mixture is more than thirty percent of the entire surface, then they turn to a major overhaul of the entire building. It involves removing the old coating and creating a new finish.

Facade overhaul of a house made of natural stone
Such restoration of the facade of a building should begin with a careful study of all necessary documentation and examination of the walls. After this, a suitable building material for finishing is selected depending on its structure and species. It is also necessary to decide on the mounting option, because the appearance of the building will depend on this: glued stone gives the building an original appearance, a ventilated façade gives it a strict and impressive outline. In this case, the old coating is completely removed.
Main stages of repair activities
Facade repair consists of a number of stages . The most important of them:
- damage assessment and study;
- calculation of the load-bearing capacity of wall structures;
- preparatory stage;
- selection of facing material and method of its application;
- installation of façade covering.
At the first stage, experts come to the site and carry out a visual inspection of the surfaces. At the same time, they can use special equipment to detect fungus and contaminants that led to the appearance of defects. Sometimes experts take samples to determine the composition of the coating. Then a special paper is drawn up, which reflects the nature and total area of damage.
Major renovation
Major repairs of the facade include the implementation of a large-scale list of services for the restoration of cladding.
The capital restoration complex includes the following measures:
- Conducting a detailed analysis of defects and damage
- Then a project is drawn up
- The old facade covering is dismantled
- The surface of the walls is carefully prepared: leveling, sealing seams, plastering, putty, painting
- Facade insulation
- Finishing with selected type of material
Thanks to competently carried out restoration, the building will be completely restored, and its service life will also increase. In the process, all communications are repaired, the foundation is restored, and thermal insulation is performed with a certain type of insulation. Decorative elements are also being reconstructed. It is generally accepted that major repairs are urgently needed for residential buildings and buildings in which the destruction of the cladding exceeds 30 percent. To overhaul a building, you will need the services of professionals. You can find out how much the service costs per 1m2 from a specialized company. It should also be noted that prices for finishing materials may differ from different manufacturers. Major repairs will eliminate all defects and improve the load-bearing capacity of the walls. Finishing and insulation should be carried out by professional craftsmen.
Typically, a wide range of facing materials is used for finishing:
- Various types of plaster
- Facade brick or tile
- Siding
- Natural and artificial stone
- Sandwich panels
In what cases is façade repair necessary?
Repairing buildings requires serious financial investments, so many property owners constantly postpone restoration work. But there are a number of signs indicating that the object is in urgent need of restoration:
- Damage to the drainage system. Rupture or deformation of a drain, funnel or other elements leads to the fact that storm and melt water flows directly along the walls of the building. This gradually destroys the wall material, worsens the thermal insulation characteristics of the house, and leads to the formation of cracks in the walls. If the damage is not repaired in time and the façade is not repaired, water will erode the foundation, which can lead to a partial collapse of the building.
- Deformation of insulation in the seams. Panel apartment buildings are often susceptible to this problem. The plaster covering the insulation cracks, exposing the thermal insulation layer. Under the influence of snow and rain, it becomes damp, swells and quickly becomes unusable. As a result, the thermal efficiency of the building decreases, the walls in the apartments become wet, and mold appears on them.
- Destruction of more than 35% of the cladding area. If the building is finished with plaster, it cracks and falls off, efflorescence (white salt stains) appears on the brick and concrete masonry, and the tiles crack and chip. Violation of the integrity of the facing materials opens up access to the walls - they are exposed to aggressive environmental factors (precipitation, ultraviolet radiation, fumes and soot), which significantly reduces the life of the building.
To maintain the facade of the house in good condition, experts recommend performing cosmetic repairs every 5–7 years. This will help avoid serious problems with walls and foundations.
Why do facades have to be repaired?
Let's start from afar. In what cases is it generally necessary to repair the facades of residential buildings or industrial structures?
- Planned repairs . For plastered buildings, it is carried out at certain intervals - simply to ensure that the appearance of the facade meets aesthetic requirements. Over time, the paint inevitably fades and untidy streaks appear.
- Various damage to facades . First of all, cracks and shedding of plaster.
If everything is clear with the first point, then what could cause the appearance of cracks and, in general, any visible defects of the facade? The list of reasons is quite long.
- Uneven shrinkage of a building can lead to deep cracks . What is especially unpleasant is the appearance of so-called dynamic cracks, which continue to expand and deepen.
The cause of this crack is the soil that has subsided along with the foundation.
Important:
in this case, primary attention should be paid not to the condition of the facade, but to research into the condition of the soil and foundation. Ground movements may well lead to the collapse of walls.
- Water . It inevitably falls on the walls during slanting rain; damaged gutters can also contribute. Water has the most destructive effect on walls in the off-season: when a wet wall cools at night to a temperature below zero, ice bursts the smallest pores and quickly destroys the outer layers of the facade.
- A separate point worth mentioning is water vapor, which inevitably forms in large quantities in any living space . It is filtered through the walls and, with a large temperature difference between indoor and outdoor spaces, condenses into them. Steam differs from rainwater, first of all, in that it penetrates not only into the outer layers of plaster, but also into the joints between panels and the seams of the brickwork, into the material of the walls and ceilings themselves.
- Wind loads . As the wind bends around a building, it creates areas of high and low pressure. If a plastered facade can only be damaged by the passage of a tornado, then for a curtained façade the force of the wind should already be taken into account: cases of glass and plastic facades being destroyed by a hurricane are not uncommon.
- Daily and annual temperature changes from the point of view of the walls of a building are a series of continuous expansion and contraction of the material . Of course, heating and cooling also contribute to the destruction of building facades, and the greater the temperature delta, the more often the facades have to be redecorated.
Temperature changes destroy walls even where they are protected from rain.
Why do you need to repair the facade?
Repair of building facades is carried out to eliminate detected damage, restore the integrity of the cladding or update it. The work performed is aimed not only at eliminating aesthetic defects - the main advantage of the repair is to improve the operational characteristics of the object and extend its service life. Depending on the manipulations performed, the repair team is able to:
- Restore the waterproofing layer and protect the walls from the negative effects of storm and melt water.
- Improve the thermal insulation of the facility, helping to reduce heating costs.
- Increase the moisture and vapor permeability of walls and prevent the appearance of efflorescence and mold.
Restoration allows you to update the architectural image of a building, making it more comfortable for living or working. The result of the repair largely depends on what kind of construction work was carried out.
Technologies
What could be the technology for repairing the facade of a building? Without pretending to fully cover all possible methods, we will analyze several frequently encountered scenarios.
Cracks
For dynamic (continuing to deepen and widen) and static (fixed size) cracks, different repair techniques are used.
Dynamic cracks
The technology for repairing facades is determined by their material and the degree of damage:
- For a crack in the plaster layer, it is enough to clean the plaster 200 millimeters around and, having primed the surface of the wall, re-plaster it with the obligatory laying of a reinforcing façade fiberglass mesh.
- Deep cracks in the brickwork are repaired by partially dismantling it to a depth of half a brick. Then the masonry is done again in the resulting niche.
Here the outer layer of masonry will have to be removed again.
- The crack in reinforced concrete is expanded (widened and deepened), then filled with high-strength cement mortar. As an option, the solution is injected into the depth of the crack with a special syringe.
- In the case of cracks in load-bearing walls, they are additionally strengthened with steel rods and so-called tension ties: structural elements are heated by a strong current during installation and, compressing when cooled, tighten the edges of the crack.
Static cracks
It is very simple to eliminate static cracks in the facade with your own hands:
- The crack is opened again;
- Its edges are primed;
- Then the cavity is filled with elastic putty based on synthetic resins, preferably silicone.
Repairing crumbling plaster
Redecorating a façade often involves restoring partially destroyed plaster. How it's done? Here are the instructions.
- All weak façade plaster is removed. Alas, there is quite a lot of work to be done - tapping the entire surface of the facade with a light hammer and identifying potential weak points. Then it is stripped down to the ground.
- The masonry seams deepen by 1-2 centimeters.
- The surface of the masonry is cleaned of old mortar and plaster residues with a wire brush and swept with a hair brush.
- Irregularities in the masonry less than 3 centimeters deep are filled with mortar. Deeper ones are reinforced with mesh before cementing. As an option, broken bricks or tiles can be used for filling. Before plastering, the surface should be as level as possible: otherwise the plaster layer will be of different thicknesses and may crack during drying.
- The covering layer of plaster is restored as follows: the surface is wetted from a sprayer; a solution based on coarse sand is sprayed; then soil is poured onto it to a level 2-3 millimeters below the surrounding plaster. The final, covering layer is applied over the set primer.
Advice:
if the total thickness of the plaster does not exceed one centimeter, you can not complicate your life and plaster the facade in one layer.
Here the condition of the façade is such that the only way out is to strip the walls down to the masonry and re-plaster them.
Restoring the outer layer of plaster
What to do if the plaster has retained its strength, but its appearance leaves much to be desired? Major repairs of facades in such cases will be a waste of money and time. Enough re-cladding:
- The outer layer is cleaned with a metal brush.
- Repairs inevitable minor defects.
- The covering layer of plaster is reapplied and after drying and priming the facade is painted.
As an option, plaster that has begun to weather can be restored by painting it with cement laitance or priming it with an aqueous solution of PVA glue. Some methods of repairing facades are mentioned in the video at the end of the article. Perhaps the information will be useful to you.
Here all the work came down to restoring the outer layer of plaster.
Curtain facades
Finally, the most popular facade repair technology recently comes down to the fact that the main wall is completely covered with a curtain structure. This can be siding fixed to a wooden sheathing, sandwich panels with a layer of insulation under a decorative coating, or a ventilated facade made of porcelain stoneware. There are plenty of options. A ventilated facade often represents a complex solution: it not only performs protective and decorative functions, but also hides an insulation layer protected by a wind barrier. Most often you can see basalt wool in this role. This design allows you to solve several facade problems at once:
- Protect walls from water ingress during slanting rain.
- Reduce the temperature delta on the surface of the walls many times over.
- Move the dew point outside the wall.
- Reduce wind erosion of the surface to zero (the problem in areas with sandy soils does not seem far-fetched: the wind often carries sand with it, which destroys any plaster in a few years).
- Finally, insulation provides a reduction in heating and air conditioning costs, and at the same time much better sound insulation.
A curtain wall allows you to not only give the walls an attractive appearance, but also make them more durable, and at the same time insulate the house.
Types of facade repairs
Experts distinguish three types of facade repairs:
- Capital - aimed at eliminating damage that could lead to the destruction of enclosing structures.
- Cosmetic - necessary to restore the integrity of the cladding and return the building to a presentable appearance.
- Current - involves performing scheduled maintenance work on the facility: eliminating minor defects, cleaning walls from plaque and dirt, and so on.
Let's look at each of them in more detail.
Capital
Major repairs of the facade are carried out in the following cases:
- Detection of serious cladding defects.
- Redevelopment of a building and/or change of its purpose (a residential building is converted into an office building or store).
- Partial destruction of walls.
Overhaul may include various types of work:
- Restoration of brickwork, replacement of damaged wall material.
- Additional waterproofing of seams.
- Replacement of heat insulator and insulation of the structure.
- Dismantling damaged drainage elements and installing new drainage systems.
As a rule, major renovation of building facades also involves the complete removal of old paint or plaster and the removal of decorative panels. Cracks and chips are filled with cement mixture, then the walls are primed and puttied. The final stage is covering the object with new decorative materials.
Overhaul allows you to completely change the appearance of the building, protect the load-bearing structures from aggressive environmental influences, and improve the hydro- and thermal insulation of the building. It is recommended to carry out major repairs as the building becomes dilapidated, every 15–20 years.
Cosmetic
Cosmetic repairs are necessary to maintain the aesthetic appearance of the building facade. It does not involve major reconstruction, but by updating the cladding it protects the walls from negative influences and helps to increase the service life of the facility.
This type of repair usually includes the following types of work:
- Removal of obsolete facing material.
- Sealing of seams.
- Alignment of cracks and chips, filling them with plaster mixture.
- Primer, wall putty.
- Painting the building.
During cosmetic repairs, areas of cracked plaster, dirt stains, stains, and mold are removed. As a result, it is possible to completely restore the original appearance of the structure or change its exterior in accordance with a new design project.
Current
Current repairs of building facades are aimed at eliminating minor defects and avoiding serious destruction of wall materials. For example, current work means:
- Removing graffiti from walls.
- Cleaning stains of dirt and water stone using sandblasting equipment.
- Washing the facade.
Regular maintenance of the building extends the service life of hydro- and thermal insulation and maintains the attractiveness of the building's cladding.
When may house façade repairs be necessary?
Let's look at the main types of defects in the facade of a house for which you will need to carry out repairs. It is better to carry out this inspection by a special commission, since it will be able to reliably describe the level of destruction. This commission is made up of representatives of residents, the regional operator and the main persons of the management company. I recommend taking care in advance of creating a group of people who have ownership rights to the house. Reconstruction of the facade is necessary in the following cases:
- The insulation that fills the seams between the blocks and panels has crumbled. With this problem, water gets inside the load-bearing structures, which causes even greater destruction and problems with the appearance of fungus and mold on finishing and building materials.
- The plaster collapsed on an area of more than 35% of the area of the façade system.
- The drainpipes have become unusable. This entails water entering the façade structure.
If the commission discovers such damage, it will have to decide on the necessary work to repair the facade. However, if we are talking about a private low-rise house, the owner of which is you yourself, the decision to further repair the facade of the house lies solely on your shoulders, and you can come to this work even if you are simply bored with the aesthetics of the appearance of the house.
Features of repair of facades of various types
The specifics of facade repairs depend on the type of exterior finishing of the building. The structure can be lined with brick, plastered, painted, decorated with wooden or ventilated panels. Let us consider the features of repairing facades of various types in more detail.
Repair of brick facades
The main problems that brick-clad facades are susceptible to:
- Efflorescence: white salt stains resulting from exposure to storm and melt water.
- Cracks and chips: over time, the brick loses strength and becomes more friable. As a result, the masonry is deformed.
If a building has been in use for a long time, the brickwork may partially collapse - in this case, the structure requires serious restoration. Work begins with an assessment of the damage caused to the object. If there are no significant defects, cosmetic repairs are carried out:
- The facade is cleaned of salt stains, burning and soot.
- Destroyed bricks are replaced with new ones.
- Cracks are filled with cement mortar or putty.
The main task of specialists is to restore the integrity of the masonry. It is better to carry out work in preparation for the onset of the autumn-winter period, before the onset of rains: cracked brick absorbs water well and quickly collapses under its influence.
Restoration of wooden facades
Wooden facades are sensitive to high humidity, so they must be regularly treated with an antiseptic solution. It penetrates deep into the wood structure and fills its pores, causing the wood to lose its ability to absorb moisture. This protects the walls from rotting and mold. Antiseptics also make wood unsuitable for the development of insects.
The main feature of repairing wooden facades is the choice of products designed specifically for wood processing. Regular maintenance of wooden structures significantly increases their service life and allows you to maintain the aesthetic appearance of buildings.
Step-by-step instructions for repairing the facade of a house
The sequence of facade repair depends on the building material from which the walls are made, as well as the finishing features.
Repair of plastered facade
- You need to inspect the surfaces. Mark deep damage with a marker. If you find fallen plaster, tap all surfaces to identify air chambers. Treat the walls with a mallet. Collapse of plaster can interfere with subsequent work, so tap the walls until a durable layer is found.
- Analyze the condition of the brick under the fallen off layer of plaster. In these places it often turns out to be defective and fragile. Such bricks need to be removed, and if excessively deep holes are found, they should be repaired. The recesses must be sealed using a mortar of cement and sand. The mixture should include at least one part cement to two parts sand.
- After the mixture has dried, you can proceed to plastering the walls. Level the surfaces with a wet sponge, then level the adjacent area of the next plaster layer.
- Start painting the walls. Before doing this, be sure to go over the areas with new plaster with a roller, otherwise multi-colored spots may appear. In my opinion, it is better to use water-based paints.
If your house is insulated with foam plastic slabs, on which obvious damage is visible, then take the following steps:
- Using a mounting knife, cut off the reinforcing mesh around the defect;
- Clean the hole from unusable foam;
- Along the perimeter of the hole, insert pieces of thin wire into the plate (several cm deep);
- Soak the surface of the foam and apply foam to the hole, then wait until it dries;
- Remove excess foam;
- Treat the defective area with putty. It is not necessary to make a patch from reinforcing mesh. But if you still want to do this as a precaution, then this patch should be at least 5 centimeters larger than the hole.
- After that, start painting.
Repair of wood and plastic sheathing
- Using a grinder, cut off the unusable area. Try not to touch neighboring areas. Remove the resulting panel cutout.
- Prepare a piece of replacement panel. The joints should be as smooth as possible.
- Make two slits in the back of the new panel. This is necessary so that the panel can bend and thereby be fixed more easily.
- The areas adjacent to the supporting grid must be coated with liquid nails. Then you should bend the panel and insert it into the place to be replaced.
Wooden linings are repaired somewhat differently. Remove the damaged trim and clean out the vacant space. The new piece cannot be inserted into the lock, so remove the tenon from one side of the piece. After application, one edge will go into the lock, and the second will need to be nailed.
Repair of facades of old wooden buildings
Let's consider an option in which you need to simultaneously repair the facade walls and replace the cladding. Proceed according to the following step-by-step instructions:
- Step 1: Remove any outdated trim. Consider the crowns of the log house and foundation. If you need to replace rotted crowns of a log house, you will need the help of specialists.
- Step 2. Remove the rotten logs, after which you will need to take measurements and prepare new ones.
- Step 3: Create a columnar foundation. The depth should be at least 1 meter, and the thickness of the sand cushion no more than 25 cm. The pillars should be placed at a distance of approximately 2.5 meters from each other.
- Step 4. After the cement has hardened, the logs should be placed on the pillars and the frame should be lowered into place. Don't forget about waterproofing. If the frame is warped, then it will be necessary to cut new window and door openings.
- Step 5. Saturate the wood with antiseptics.
- Step 6. Start covering. I recommend immediately insulating the walls, so purchase mineral wool at least 10 centimeters thick.
So, what needs to be done to carry out high-quality repairs to the facade of your home? First of all, you need to attract a commission that will inspect the building and make a decision on future manipulations, or assess the condition of the facade of the house yourself if you are the sole owner of the residential premises. After this, you should stock up on the necessary materials and, if necessary, call experienced specialists. The last stage will be the work itself, which depends on the specific situation.
Repair stages
The sequence of restoration work largely depends on the type of repair (cosmetic, capital or current) and the type of facade. But in most cases, reconstruction consists of the same basic steps:
- Visit of specialists to the site and determination of the scope of work. The team inspects the building, checking the condition of gutters, brick or concrete masonry, and noting the presence of cracks, chips, stains of dirt and mold. After this, a detailed technical specification is drawn up, construction materials are purchased and an estimate is signed.
- Preparing for repairs. If the building needs serious restoration, then before finishing the façade, the roof and drainage system are reconstructed. Then scaffolding is installed and temporary structures (for example, advertising banners and banners) are removed.
- Surface cleaning. Specialists remove old facing material, eliminate efflorescence, and clean the walls from stains of mold and dirt. For this, both hand tools and sandblasting equipment, and special chemical compositions can be used.
- Restoration of hydro- and thermal insulation of the building. This stage is carried out only in case of major repairs.
- Filling seams and cracks with cement mortar or plaster.
- Primer, leveling the walls with putty, preparation for finishing.
- Plastering or painting the facade. If ventilated panels are used, install them.
- Dismantling of scaffolding and delivery of the object to the customer.

Carrying out restoration work
The overhaul of the facade is an action to restore or replace materials whose wear has exceeded the permissible limit, and further operation is impossible.
The Law “On Major Repairs”[4] contains an approximate list of necessary work. Their implementation is controlled by regional authorities, and direct work is carried out by special non-profit organizations.
The following work is included in the overhaul of the facade:
- plastering of external surfaces;
- applying protective material to joints;
- replacement of insulation;
- glazing of balconies and loggias or their replacement of glazing elements, including windows;
- improvement of the entrance to an apartment building;
- installation of a new drainage system;
- installation of flag holders and signs.
The deterioration of each structure is different, which leads to different repair technologies. A specific list is compiled by specialists after the examination. This is reflected in the conclusion...
