In all passageways and at heights below 90cm: tempered or laminated safety glass. Spanish Technical Building Code (CTE). If the original was single pane, it must be upgraded to safety glass. We start with a measurement visit. We measure the existing opening with millimetre precision, identify the type of glass to be replaced (tempered, laminated, Climalit), and verify the fixing system to the frame (silicone, PVC profile, neoprene seal) so that the replacement is identical to the original. We provide a fixed quote during the same visit.

Climalit double glazing is the standard for thermal and acoustic insulation in modern construction. Two panes of glass separated by a dehydrated air chamber and sealed at the perimeter. If one pane of the Climalit unit breaks, the entire unit must be replaced because the air chamber becomes contaminated with moisture and loses its insulating function. Replacement is slightly more expensive but technically the only correct solution. We typically see three common causes. Firstly, strong wind closing a sliding door with such force that it hits the frame and cracks the tempered glass. This happens particularly in areas with strong westerly or easterly winds like La Mata, Punta Prima, or Pilar de la Horadada when doors are left improperly closed. Secondly, children's balls or accidental impacts against window panes on ground floors or terraces. Thirdly, attempted burglaries where the thief breaks the balcony door glass to enter, which is relatively rare in the area but does occur. The correct protocol when a pane of glass breaks involves three steps. First, immediately remove all loose fragments to prevent accidents, which is especially important with children or pets in the house. Second, provisionally cover with a thick plastic sheet or board if the area is externally accessible and there's a risk of intrusion. And third, call the glazier as soon as possible for measurement and replacement. The urgency depends on whether the area is watertight or not. A window overlooking an interior patio can wait 2-3 days without issue. A balcony door or exterior window with a risk of rain ingress or theft requires urgent replacement.

Glass with official manufacturer's warranty (5 years for defects) plus our installation coverage. For isolated chalets, single-family homes in affected areas, or owners with previous experience of attempted burglaries, we recommend high-security cylinders such as Cisa Astral S, Mul-T-Lock MT5+, Tesa T80 Plus, or Mottura Champions. These raise the rating to EN1303 Grade 6, adding all anti-features (bumping, picking, drilling, extraction). They come with a manufacturer's anti-theft insurance guarantee. This guarantee is relevant. If, despite everything, entry is gained and you can prove the cylinder was tampered with, the manufacturer covers part of the damage. All this investment in a security cylinder loses meaning if key copies are freely made at any neighbourhood hardware store. The registered key of a security cylinder can only be duplicated at the official manufacturer's distributor by presenting the owner's card, which we provide upon installation. Without this card, no copy is possible. This means you control exactly how many keys exist and who has them. You will never have the uncomfortable doubt of whether the neighbourhood locksmith or a duplicator might have kept your key pattern for future use.

The price for changing cylinder locks in Sarrià typically ranges between €54 and €350. The final figure depends on the property's condition, materials, and labour time. We always provide a fixed quote before starting. Call us, write to us on WhatsApp, or request your quote online — we'll respond in less than 10 minutes during business hours. For apartments in blocks with neighbours, an active community, and natural surveillance, we recommend medium-high security cylinders like Tesa T80 or Cisa Astral. Effective anti-bumping, registered key (cannot be copied without your authorisation), EN1303 Grade 5 certification (resistance to manipulation for years). Reasonable cost and significant real improvement over the standard.
