Rising damp, roof leakage, interior condensation, and efflorescence due to saltpetre. Diagnosis before action. Chemical injection, exterior waterproofing, breathable coating, or ventilation depending on diagnosis. Treatment requires addressing the water source, not the interior 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 ensuring exterior watertightness do we repair the interior wall.

Formal guarantee on the treatment. If damp reappears in the same spot, we'll return. The most common mistake with damp is repainting the affected wall. It looks fine for the first month, then the damp reappears, worse than before. The new paint creates a barrier that traps water inside the wall. Dampness is not cured by painting. It's cured by identifying the water source and stopping it 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 diagnostic technical visit before quoting anything. The difference between treating damp correctly or incorrectly changes the durability of the result between five years and six months.
