Steps for Partial Building Waterproofing with Reformia
Partial waterproofing services for buildings.
1. Inspect areas affected by moisture
The technician will conduct a thorough inspection of terraces, roofs, balconies, and facades to identify moisture stains, efflorescence, and deteriorated areas. This initial assessment is essential to determine the scope of partial waterproofing and the budget, ranging from 300 € to 3,500 € depending on the affected area.
2. Identify the source of leaks
The root causes of leaks will be determined, such as facade cracks, deteriorated joints, or damaged membranes. Correctly identifying the source allows for selecting the most effective solution: crack sealing from 8.25 €, terrace waterproofing with acrylic paint from 12.5 €, or specialized treatments.
3. Clean and prepare the surface
The affected areas will be thoroughly cleaned, removing moss, algae, dust, and debris from old materials. Proper surface preparation is crucial for waterproofing products, such as bituminous membrane (18.75 €) or polymeric mortar (15 €), to adhere correctly.

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.
Size of the area to be waterproofed
The total price depends directly on the square meters to be treated. Larger surfaces require more material and more working hours, significantly affecting the final budget.
Type of area and location within the building
Terraces, roofs, balconies and wet areas have different levels of difficulty and risk. Access and height also influence the costs of scaffolding or necessary safety measures.
Waterproofing materials and systems chosen
Options include asphalt membranes, polyurethane, waterproof mortars or resin systems. The quality and durability of the selected material varies considerably in price.
Previous condition of the surface and preparatory work
If the surface requires prior repairs, intensive cleaning or partial demolition of existing elements, labor costs and total time increase.
General Information
Partial waterproofing services for buildings.
Partial waterproofing of buildings is an effective solution to prevent water leaks in specific areas of the structure, such as terraces, balconies, roofs, or facades. This type of intervention is especially useful when moisture problems are localized to specific areas of the property, allowing you to repair only the affected zones without needing to waterproof the entire building.

Frequently Asked Questions
What is the difference between partial and full waterproofing?
Partial waterproofing is applied only in specific areas where there are leak problems, such as a terrace or balcony. Full waterproofing covers the entire roof or facade of the building. Partial is more economical and faster, ideal when problems are localized to specific areas, while full offers comprehensive protection and is recommended for older buildings or those with multiple leaks.
How long will the applied waterproofing last?
The duration depends on the material used and the quality of the application. Basic products offer 2-3 years of warranty, standard products 5 years, and premium products up to 10 years. However, with proper maintenance (regular cleaning and inspections), waterproofing can last 15-20 years. Factors such as intense sun exposure, extreme temperature changes, and lack of maintenance can reduce lifespan.
Is it necessary to vacate the area during waterproofing?
It depends on the area and the material used. For waterproofing on terraces or balconies, it is generally not necessary to evacuate the home, but it is recommended not to use the area for 24-48 hours after application. If work is done on roofs or facades, access may be limited. Modern products have minimal odor and dry quickly, minimizing inconvenience. Consult with the professional about specific precautions.
What factors affect the price of partial waterproofing?
The price depends on several factors: surface area to be treated (m²), type of waterproofing material (bituminous, polyurethane, epoxy resin), surface condition (if prior repairs are needed), complexity of access, need for additional drainage systems, and geographic location. The urgency of the work and whether a prior technical diagnosis is necessary also influence the price. A professional can better adjust the quote after an on-site inspection.
How do I know if I need partial waterproofing?
Signs that you need waterproofing include moisture stains on ceilings or walls, visible leaks after rain, paint or plaster peeling, mold or bad odors in specific areas, and cracks in exterior surfaces. If only one or two areas of the building are affected, the partial solution is appropriate. If the problem is widespread, a more extensive waterproofing may be necessary. A professional can provide an accurate diagnosis through inspection.
