We install double glazing in Sant Joan Despí. We visit the property, assess the work, give you a clear price, and get started. When a client calls us for an emergency (keys left inside, lost key, locked mechanism), we first evaluate if non-destructive opening is possible. Most standard locks can be opened with professional techniques (lock picking, impressioning, pin manipulation) in 15-30 minutes without damaging the cylinder. This saves the client the cost of replacing the entire cylinder. For high-end anti-bumping cylinders, non-destructive opening may not be possible, and the only solution is to drill the cylinder and replace it, which is more expensive but leaves the door like new with a new reinforced security cylinder.

Changing only the cylinder is a 30-45 minute operation per door. The mechanical lock remains, 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 the one we recommend when the lock is of good quality and in good condition. Changing the complete lock costs more and is justified when the lock is old or of low quality and we want to take advantage of the change to upgrade the security level. This operation takes 60-90 minutes per door. Non-destructive opening when possible, complete lock or cylinder replacement, installation of high-security anti-bumping cylinders. The mirror's anchoring to the wall is what separates a professional installation from one with risk. For small and medium mirrors up to 5 kg, specific double-sided tape for mirrors on a clean surface is sufficient (provided the wall is stable and there is no humidity). For large mirrors and all bathroom mirrors with ambient humidity, mechanical anchoring with specific screws behind the mirror or hidden side clips is used. Never use common adhesive like silicone to fix mirrors. With humidity and weight, they eventually give way, and a fallen large mirror is a serious accident.
The typical residential client is a working-class or middle-class Spanish resident.

The price of double glazing in Sant Joan Despí typically ranges between €62 and €616. The final figure depends on the property's condition, materials, and working time. We always provide a fixed quote before starting. For a home on the Costa Blanca 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 our best sellers. These cylinders have security pins that prevent the bumping technique, that sharp blow with a special key that opens any standard cylinder in less than 60 seconds. They come with a registered security key, which cannot be copied without authorisation at any hardware store. And they have European EN1303 certification, guaranteeing resistance to manipulation for years. Their cost is reasonable, and the real security improvement is enormous.
