Chemical injection, external waterproofing, breathable coating, or ventilation depending on diagnosis. Rising damp, roof leaks, internal condensation, and saltpetre efflorescence. Diagnosis before action. Treatment requires addressing the water source, not the internal symptom. If the roof is damaged, the entire waterproofing needs renewal with new asphalt 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.

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 from five years to six months. 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. The new paint creates a barrier that traps water inside the wall. Damp 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. Formal guarantee on the treatment. If the damp reappears in the same spot, we'll come back.
