Tempered glass is the standard for balcony doors, large windows, and areas at risk of impact. Its distinguishing feature is that when it breaks, it shatters into thousands of small, blunt fragments that do not cause severe cuts, unlike large, sharp fragments from conventional glass. Spanish regulations (CTE) require tempered or laminated safety glass in all passage areas and at heights below 90 cm. If your broken glass was conventional single pane, we are obliged to replace it with tempered glass to comply with regulations.

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 will not work with the old one. This is 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. When a client calls us urgently (keys left inside, lost key, jammed lock), we first assess if non-destructive entry 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 entry may not be possible, and the only solution is to drill out the cylinder and replace it, which is more expensive but leaves the door as new with a new, reinforced security cylinder. The most frequent causes we see are three. First, strong winds that close a sliding door with such violence that it hits the frame and cracks the tempered glass. This happens especially in areas with strong westerly or easterly winds like La Mata, Punta Prima, or Pilar de la Horadada when doors are left improperly closed. Second, children's balls or accidental impacts against window panes on the ground floor or terrace. Third, attempted burglaries where the thief breaks the balcony door glass to enter, which is relatively rare in the area but does occur.

Complete lock change or just the cylinder, depending on the case. Quality brand and new set of keys. 30 days on labour. Premium cylinders with official manufacturer warranty up to 10 years. If the lock is in good condition, just the cylinder is the most economical. If it's old or low quality, a complete change is a better investment.

The price for custom mirrors in Cerdanyola del Vallès typically ranges between 62 and 581 euros. The final figure depends on the property's condition, materials, and labour 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-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 strike with a special key that opens any standard cylinder in under 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 tampering for years. Their cost is reasonable, and the real security improvement is enormous. We begin with a measurement visit. We precisely measure the existing opening, identify the type of glass to be replaced (tempered, laminated, Climalit), and verify the fixing system to the frame (silicone, PVC profile, neoprene gasket) so that the replacement is identical to the original. We provide a fixed quote during the same visit.
