Rising damp, roof leaks, internal condensation, and saltpetre efflorescence. Diagnosis before acting. Chemical injection, exterior waterproofing, breathable coating, or ventilation depending on diagnosis. 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 asphalt membrane 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 guaranteeing exterior watertightness do we repair the interior wall.

The most common mistake with damp is repainting the affected wall. It works for the first month, and then the damp reappears, worse than before. Now the new paint creates a barrier that traps water inside the wall. Damp is not cured by painting. It is cured by identifying the source of the water and cutting it off at its entry point. Only then do we repair the wall with the appropriate technique and repaint. There are four types of damp we commonly see on the Costa Blanca, each with a different cause, diagnosis, and treatment. Confusing them inevitably leads to ineffective treatments and wasted money. That's why we always start with a technical diagnostic visit before quoting anything. The difference between treating damp correctly or incorrectly changes the durability of the result between five years and six months. This is damp that rises from the ground through walls by capillary action in porous materials. It manifests as a damp stain on the ground floor up to a metre high from the ground, often with white efflorescence (salts that crystallize when water evaporates). It is typical in old ground-floor homes, especially in areas with a high water table near the sea.

Whether the property is furnished or not: If you need painters to move furniture and other similar tasks, the price may increase slightly. Wall condition: The wall may be damaged (with cracks or holes) and preliminary work may be necessary to prepare the surface. Quality of materials: Whether we're talking about paint or wallpaper, not all materials have the same quality or price. We are renovating the whole house and want to contact a painter for a trial job. If we are happy with their quality and price, we intend to give them the rest of the house to work on.
