The treatment requires addressing the source of the water, not just the internal symptom. If the roof is degraded, the entire waterproofing needs to be renewed with new asphalt felt or a sprayed 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. Call us, message us on WhatsApp, or request a quote online — we'll reply in under 10 minutes during business hours.

Yes, a specific paint system for damp walls: an anti-salt sealing primer, breathable microporous paint that allows the wall to breathe. This is humidity that rises from the ground through walls by capillary action of porous materials. It manifests as a damp patch on the ground floor up to one metre high from the floor, often with white efflorescence (salts that crystallise as the water evaporates). This is typical in old ground-floor homes, especially in areas with a high water table near the sea.
