First, immediately remove all loose fragments to prevent accidents, which is especially important with children or pets at home. Second, provisionally cover with a thick plastic sheet or board if the area is accessible from the exterior and there is 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 facing an interior patio can wait 2-3 days without issue. A balcony door or exterior window with a risk of incoming rain or theft needs urgent replacement. We start 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.

Tempered glass is the standard for balcony doors, large windows, and areas at risk of impact. Its distinctive 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 security laminated glass in all high-traffic areas and at heights below 90 cm. If your broken glass was simple conventional glass, we will replace it with tempered glass as mandatory to comply with regulations. Laminated glass, formed by two panes joined by an inner transparent PVB layer, is the premium option for doors and windows at risk of theft. When it breaks, the fragments remain adhered to the PVB layer, and the window maintains significant residual resistance. This is what we recommend for accessible ground floors or detached villas in high-risk areas. The most frequent causes we see are three. First, strong wind that slams a sliding door with such force 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 gain entry, which is relatively rare in the area but does occur.

All that investment in a security cylinder loses its meaning if key copies are freely made at any local hardware store. The registered key of the security cylinder can only be duplicated by the official manufacturer's distributor upon presentation of the owner's card, which we provide upon installation. Without that card, no copy is possible. This means you control exactly how many keys exist and who has them. You'll never have the uneasy doubt of whether the neighbourhood locksmith or a copier might have kept your key pattern for future use. For detached villas, 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 grade 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. Official manufacturer's warranty 5-10 years depending on brand and model. Plus 30 days on labour.

The price of security locks in Cerdanyola (Mataró) typically ranges between 53 and 510 euros. The final figure depends on the property's condition, materials, and labour time. We always provide a fixed quote before starting. 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. Call us, message us on WhatsApp or request your quote online — we'll respond in under 10 minutes during business hours.
