How much does it cost to repair cracks?
The average price for repairing cracks starts at around 30 €/m² or 20 €/m linear. The price can increase significantly depending on the type of material to be worked on, since the work is more difficult on single-layer mortar than on plaster, for example. Additionally, other factors influence the budget such as the length, width, and depth of the cracks. Also the proportion of surface affected by them, their location, or whether you need to use elevated work equipment to repair cracks on exterior walls can increase the cost. In this way, repairing 10 m² of concrete facade with cracks and applying paint afterwards to level it will have an approximate cost of 350 €.

Steps to repair cracks in the facade with Reformia
The average cost of repairing cracks in a facade is around 30 €/m² on interior or exterior rendered surfaces and around 14 €/m² on plaster finishes. The budget, however, can increase depending on the type of crack (depth or width) and the coating that needs to be worked on.

1. Inspect and classify the type of crack
The professional examines the crack to determine its depth, extent, and cause. This assessment is crucial for selecting the right treatment, as simple interior wall cracks start from 250 €, while facade cracks are around 800 €. Proper inspection prevents incomplete repairs and future structural issues.

2. Clean the affected area and remove debris
Dust, debris, and loose materials are removed from the crack through brushing and deep cleaning. This step is essential for proper adhesion of the filler or repair mortar and ensures a long-lasting repair. Thorough cleaning is especially important in facade repairs where costs reach 800 €.

3. Prepare the necessary materials and tools
Fillers, mortars, or sealers are selected and prepared based on the type of crack detected. For ceiling cracks (400 €) or facades, specific materials are used to ensure flexibility and durability. Having the right materials ready optimizes work time and final result quality.

4. Apply filler or repair mortar
The repair material is applied into the crack using putty knives or caulking guns, filling it completely. This step varies in complexity depending on location: concrete pool cracks (1,200 €) require special waterproof mortars. Uniform application is key to prevent future leaks or peeling.
What can change your final price
Even similar projects can end with different budgets. These are the factors that most often push costs up or down.
Crack type and depth
Superficial or shrinkage cracks are more economical to repair, while deep structural cracks require more complex techniques and specialized materials, significantly increasing the cost.
Coating material
The price varies depending on whether the facade is rendered (30 €/m²), plastered (14 €/m²) or has other treatments such as decorative paint or insulation, each requiring different products and application methods.
Extent and location of cracks
Isolated cracks in accessible areas cost less than multiple fissures distributed across the entire facade or located in hard-to-reach places that require scaffolding or special equipment.
Need for preparatory or complementary work
If cleaning, removing old coatings, treating moisture issues or applying special primers before repair is necessary, these additional works will significantly increase the total budget.
