The treatment requires addressing the source of the water, not the internal symptom. If the roof is damaged, the entire waterproofing needs renewal, either 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 specialised facade paint that covers micro-cracks. Only after ensuring the exterior is watertight do we repair the interior wall. Chemical injection, exterior waterproofing, breathable coating, or ventilation depending on the diagnosis. Rising damp, roof leaks, interior condensation, and saltpetre efflorescence. Diagnosis before action.

There are four types of damp we commonly see on the Costa Blanca, each with a distinct 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 providing any quote. 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. Now the new paint creates a barrier trapping the water inside the wall. Damp is not cured by painting. It's cured by identifying the source of the water and stopping it 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 return.

San Miguel de Salinas is an inland municipality about fifteen kilometres from Torrevieja, in the Vega Baja region. It has about ten thousand inhabitants; the population is a mix of resident Spaniards and foreign owners who sought to move away from saturated coastal developments. This intermediate position has a specific technical consequence. The local supply of professionals is limited; self-employed tradespeople working here don't have 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, non-guaranteed jobs. 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 select the product compatible with each material (stoneware, marble, microcement, parquet) after an initial assessment. This is precisely what prevents scratching or dulling new surfaces.
