The treatment requires addressing the source of the water, not the internal symptom. If the roof is degraded, the entire waterproofing needs to be redone with new roofing felt or a projected liquid polyurethane system. If the facade has structural cracks, they are sealed with flexible sealant and repainted with specific facade paint that covers micro-cracks. Only after ensuring external watertightness do we repair the interior wall. Chemical injection, exterior waterproofing, breathable coating, or ventilation depending on the diagnosis. Rising damp, roof leaks, internal condensation, and efflorescence from saltpetre. Diagnosis before acting.

Specific to homes on the seafront. Saltpetre settles on exterior walls, penetrating with moisture. It emerges upon evaporation, forming white or bluish stains that peel paint from the inside. The treatment involves washing with specific chemicals, neutralising remaining salts with anti-efflorescence products, and applying a siloxane-type paint system that allows the wall to breathe without letting water in. This is dampness that rises from the ground through walls due to the capillarity of porous materials. It manifests as a damp stain on the ground floor up to a height of one metre from the ground, often with white efflorescence (salts that crystallise as the water evaporates). It is typical in old ground-floor homes, especially in areas with a high water table near the sea. There are four types of dampness we commonly see on the Costa Blanca, each with distinct causes, diagnoses, and treatments. 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 dampness correctly or incorrectly changes the durability of the result between five years and six months.

No, we choose the compatible product for each material (gres, marble, microcement, parquet) after prior assessment. This is precisely what prevents scratching or dulling new surfaces. The treatment involves adequate ventilation combined with interior thermal insulation. Installation of bathroom and kitchen extractors with correct airflow, and cross-ventilation for rooms. In severe cases of very cold walls, application of interior insulation with projected cork or sandwich panels. Without solving the cause (vapour that cannot escape), any applied paint will darken again. This is water entering from the outside due to defects in flat roof waterproofing, poorly sealed structural joints, or degraded exterior paint. It manifests as stains on the ceiling or upper part of interior walls, often coinciding with rainy periods.
