The treatment requires addressing the source of the water, not the internal symptom. If the roof is degraded, the entire waterproofing must be renewed with new asphalt felt or a projected liquid polyurethane system. If the facade has structural cracks, they are sealed with elastic sealant and repainted with specific facade paint that covers micro-cracks. Only after ensuring external watertightness do we repair the interior wall. There are four types of damp 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 damp correctly or incorrectly can change the durability of the result from five years to six months. Rising damp (capillarity), roof leaks, internal condensation, and saltpetre efflorescence. Diagnosis before action.

Replacing just the lock cylinder is a 30-45 minute job per door. The mechanical lock stays, and we only replace the inner cylinder where the key fits. The new key is completely different and won't work with the old one. It's the most economical option and what we recommend when the lock is good quality and in good condition. A full lock replacement costs more and is justified when the lock is old or low quality, and we want to use the change to upgrade security. The operation takes 60-90 minutes per door. Non-destructive opening when possible, complete lock or cylinder replacement, installation of high-security anti-bumping cylinders. This is damp that forms when indoor air, laden with vapour, touches a cold surface. Typical in kitchens and bathrooms without adequate ventilation, and also in rooms exposed to north-facing facades that get colder in winter. It appears as water droplets on windows, cold room corners, and black mould stains in cold wall areas.

If the lock is in good condition, replacing just the cylinder is most economical. If it's old or low quality, a full replacement is a better investment. For a Costa Blanca home with medium risk (urbanisation with neighbours, not isolated), we recommend a medium-to-high quality anti-bumping cylinder. Brands like Tesa T80, Mottura Champions, or Cisa Astral are what we sell most. These cylinders have security pins that prevent the bumping technique, that sharp tap with a special key that opens any standard cylinder in under 60 seconds. They come with a registered security key, which cannot be copied at any hardware store without authorisation. They also have European EN1303 certification, guaranteeing resistance to tampering for years. Their cost is reasonable, and the real security improvement is huge. 30 days on labour. Premium cylinders with official manufacturer warranty up to 10 years.
