The treatment requires addressing the source of the water, not the internal symptom. If the roof is degraded, the entire waterproofing must be renewed with new roofing felt or a liquid-applied 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 guaranteeing external watertightness do we repair the interior wall. It depends on the linear metres of affected wall. We give a fixed quote after a diagnostic visit, with no obligation.

This is dampness formed when indoor air loaded with vapour meets a cold surface. Typical in kitchens and bathrooms without adequate ventilation, also in rooms exposed to north-facing facades that get colder in winter. It manifests as water droplets on windows, cold room corners, and black mould stains in cold wall areas. Specific to properties on the seafront. Saltpetre deposits on external walls and penetrates with moisture. It emerges upon evaporation, forming white or bluish stains that peel paint from the inside. The treatment involves washing with specific chemicals, neutralising remaining salts with anti-efflorescence products, and applying a siloxane-type paint system that allows the wall to breathe without letting water through. Formal guarantee on the treatment. If the damp reappears in the same spot, we will return.

Running a new cable through a forty-centimetre thick old masonry wall is not the same as running it through a plasterboard partition. Here, technicians need to know the town and bring the right equipment, long drills, SDS-MAX bits, heavy rotary hammers, because without them, an installation that would take a morning in another city can become two days if you lack the correct tools. The reason is limescale building up inside the tank. The heating element gets coated with a thicker and thicker layer that acts as insulation. The thermostat sees the target temperature isn’t being reached and pushes more current. The bill goes up, the unit heats less efficiently, and eventually the element burns out. Sometimes the tank ruptures internally and the catastrophic leak floods the utility cupboard. Water takes longer to heat than in the first year. It comes out hot at first and cools quickly. You see an unusually high electricity bill. There are kettle-like noises that mean sediment bubbling at the bottom. The first few seconds of water look slightly cloudy. Any of these symptoms warrants a service.
