The treatment requires intervention at the source of the water, not just the internal symptom. If the roof covering 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 a specific facade paint that covers micro-cracks. Only after ensuring external watertightness do we repair the internal wall. Call us, write to us on WhatsApp, or request your quote online — we respond in less than 10 minutes during business hours. Rising damp, roof leaks, internal condensation, and efflorescence due to saltpetre. Diagnosis before action.

Formal guarantee on the treatment. If dampness reappears at the same spot, we return. The most common mistake with damp is repainting the affected wall. It works for the first month, then the damp reappears, worse than before. Now the new paint creates a barrier that traps water inside the wall. Damp cannot be cured by painting. It is cured by identifying the source of the water and cutting it off at its entry point. Only then do we repair the wall with 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's why we always start with a diagnostic technical visit before quoting anything. The difference between treating damp well or badly changes the durability of the result from five years to six months.

The treatment is chemical barrier injection. We drill small holes at the base of the wall at regular intervals and inject a resin that penetrates the wall and forms 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 flat roof waterproofing, poorly sealed structural joints, or degraded exterior 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 of insulation in Sarrià typically ranges between 208 and 2970 euros. The final figure depends on the condition of the property, materials, and labour time. We always provide a fixed quote before starting. We work with fixed price quotes. The technician assesses the task, 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 for reasons beyond the client's control.
