The treatment requires addressing the source of the water, not just the internal symptom. If the roof is degraded, the entire waterproofing must be renewed with new asphalt felt or a spray-applied liquid polyurethane system. If the facade has structural cracks, they are sealed with elastic mastic and repainted with specific facade paint that covers micro-cracks. Only after ensuring exterior watertightness do we repair the interior wall. Call us, message us via WhatsApp, or request your quote online — we respond in less than 10 minutes during business hours. Rampant capillary action, roof leaks, internal condensation, and salt efflorescence. Diagnosis before action.

Formal guarantee on the treatment. If the dampness reappears at the same spot, we return. The most common mistake with dampness is repainting the affected wall. It works for the first month, then the dampness reappears, worse than before. Now the new paint creates a barrier that traps water inside the wall. Dampness is not cured by painting. It is cured by identifying the source of the water 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 dampness we commonly see on the Costa Blanca, each with different causes, diagnoses, and treatments. Confusing them inevitably leads to ineffective treatments and wasted money. That is why we always start with a technical diagnostic visit before quoting anything. The difference between treating dampness well or poorly changes the durability of the result from five years to six months.

The treatment is chemical barrier injection. We drill small holes in the base of the wall at regular intervals and inject a resin that penetrates the wall to form a horizontal waterproofing barrier. This barrier prevents water from continuing to rise by capillary action. Over this barrier, we can repair and repaint with a breathable paint system. We guarantee the treatment for 5 years. This is water entering from the exterior due to defects in the flat roof waterproofing, poorly sealed structural joints, or degraded external paint. It manifests as stains on the ceiling or upper parts of interior walls, often coinciding with periods of rain. Removal of damaged rendering, neutralisation of salts, and application of a compatible paint system.

The price for insulation in Hostafrancs typically ranges between 208 and 2970 euros. The final amount depends on the property's condition, materials, and labour time. We always provide a fixed quote before starting. We work with a fixed quote. The technician assesses the job, tells you the total cost before starting, and that is the final amount. There are no surprise charges for travel or overtime if the job takes longer due to reasons beyond the client's control.
