Treatment requires addressing the source of the water, not the interior symptom. If the roof is degraded, the entire waterproofing must be renewed with new asphalt felt or a projected liquid polyurethane system. If the facade has structural cracks, they are sealed with elastic mastic and repainted with specific facade paint that covers micro-cracks. Only after ensuring exterior 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, without obligation.

It manifests as stains on the ceiling or upper part of interior walls, often coinciding with periods of rain. Treatment is adequate ventilation combined with interior thermal insulation. Installation of bathroom and kitchen extractors with correct flow rate, cross-ventilation of rooms. In serious cases of very cold walls, application of interior insulation with projected cork or sandwich panel. Without solving the cause (vapour that cannot escape), any paint applied will blacken again.
