We provide a fixed quote after a diagnostic visit, with no obligation. The treatment requires addressing the source of the water, not the internal symptom. If the roof is degraded, the entire waterproofing needs renewal with new roofing felt or a projected liquid polyurethane system. If the facade has structural cracks, they are sealed with elastic sealant and repainted with specific facade paint that covers micro-cracks. Only after ensuring external watertightness do we repair the interior wall.

Specific to homes on the front line by the sea. Saltpetre deposits on exterior walls, penetrating with moisture. It emerges during evaporation, forming white or bluish stains that peel paint from the inside. The treatment involves washing with specific chemicals and neutralising remaining salts with anti-efflorescence products. Application of a siloxane-type paint system that allows the wall to breathe without letting water pass through. This is dampness formed when indoor air, heavy with vapor, contacts a cold surface. Typical in kitchens and bathrooms without adequate ventilation, also in rooms facing north-facing facades which get colder in winter. It appears as water droplets on windows, cold room corners, black mould spots in cold wall areas. This is dampness rising from the ground through walls due to the capillarity of porous materials. It manifests as a damp stain on the ground floor up to a height of one metre from the floor, often with white efflorescence (salts that crystallise as water evaporates). It's typical in old ground-floor homes, especially in areas with a high water table near the sea.

We only ask that it's of reasonable quality and arrives on site on the scheduled day. We purchase in bulk from local distributors.

C1 cement adhesive is the most economical and sold in 25kg bags at any hardware store. It might be sufficient for tiling basic ceramic on dry interior walls. For floors, bathrooms, exteriors, or any modern, low-absorption porcelain stoneware tile, you need at least C2, ideally C2TES1 (cementitious, improved, extended open time, and reduced slip). The cost difference between C1 and C2TES1 is relatively small, but the difference in durability and resistance to detachment is enormous.
