The typical client calls because they've had a bad previous experience with a local sole trader. Poorly finished work, surprise invoices, no show when follow-up verification is needed. The offer of professional services with a real guarantee in San Miguel is limited. Arriving from Torrevieja with a verified technician, a fixed quote, and a 30-day guarantee resolves that disparity. Our most requested service is the renovation and upgrade of installations in village houses. Many homes in the centre have installations from the 70s and 80s with no serious upgrades. Electrical panels updated to REBT standards with a certificate, replacement of copper pipes with multi-layer when renovating a kitchen or bathroom, installation of air conditioning in homes that previously only relied on blinds for ventilation. The difference between before and after the upgrade is radical for clients who have lived with marginal installations for decades. For a new property owner in San Miguel, finding the right professional can be a frustrating trial-and-error process. We work here with the same standards as in any other area: technical visit, fixed quote, intervention with a 30-day guarantee, and a full invoice. We cover San Miguel town and the surrounding urbanisations, especially Las Comunidades and Blue Lagoon, where British and Irish owners are concentrated.

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 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 entry when possible, full lock or cylinder replacement, installation of high-security anti-bumping cylinders. Old electrical panels upgraded to REBT standards with a signed certificate, replacement of internal wiring when necessary, installation of separate differential switches by zone. Timeline: one or two days.

If the lock is in good condition, only changing the cylinder is the most economical option. If it's old or low quality, a full lock change is a better investment. For a home on the Costa Blanca with medium risk (an urbanisation with neighbours, not isolated), we recommend a high-quality, mid-to-high range 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 — a 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. They also have EN1303 European certification, guaranteeing resistance to tampering for years. Their cost is reasonable, and the real security improvement is enormous. 30-day warranty on labour. Premium cylinders come with an official manufacturer's warranty of up to 10 years.
