The treatment requires addressing the source of the water, not the internal symptom. If the roof is degraded, the entire waterproofing needs renewing with new roofing felt or a liquid-applied 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 exterior watertightness do we repair the interior wall. Rising damp, roof leaks, internal condensation, and salt efflorescence. Diagnosis before action. Chemical injection, exterior waterproofing, breathable coating, or ventilation depending on the diagnosis.

Formal guarantee on the treatment. If the damp reappears in the same spot, we'll return. 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 trapping water inside the wall. Damp isn't fixed by painting. It's fixed 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 result's durability from five years to six months.

San Miguel de Salinas is an inland town fifteen kilometres from Torrevieja, in the Vega Baja comarca. It has about ten thousand inhabitants and a mixed profile of resident Spaniards and foreign property owners who sought to move away from saturated coastal developments. This intermediate position has a specific technical consequence. The local professional offering is limited; self-employed workers here don't face as much competition as in Torrevieja or Orihuela Costa, and the average service quality is uneven. Some professionals are excellent, we know them. Others take advantage of the lack of alternatives to do quick jobs without guarantees. There isn't as much competition here as on the coast, and it shows in the quality of some professionals. We work in San Miguel with the same standards as in Torrevieja. No, we choose the product compatible with each material (stoneware, marble, microcement, parquet) after initial assessment. This is exactly what prevents scratching or dulling new surfaces.
