The treatment requires addressing the source of the water, not the internal symptom. If the roof is degraded, the entire waterproofing needs renewing 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 ensuring external watertightness do we repair the interior wall. It depends on the linear metres of affected wall. We provide a fixed quote after a diagnostic visit, with no obligation.

This is dampness that forms when indoor air, heavy 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 corners of rooms, black mould spots in cold wall areas. Yes, we have a specific paint system for damp walls: anti-salt sealing primer, breathable microporous paint that lets the wall breathe. The most common mistake with damp is repainting the affected wall. It works for the first month, then the damp reappears, worse than before. Now the new paint creates a barrier that traps water inside the wall. Dampness isn't cured by painting. It's cured by identifying the water source and cutting it off at its entry point. Only then do we repair the wall using the appropriate technique and repaint.
