Another frequent pattern: leaks that appear in the first month after returning to the property after the low season. Pipes inactive for months undergo thermal changes, and the pressure when reopening stopcocks reveals accumulated weaknesses. If you have left the house closed for four or five months, the first opening should be done slowly and by monitoring the meter. The entire localization process takes between 30 and 90 minutes depending on the complexity of the installation. Subsequent repair depends on the type of piping: copper with soldering, multi-layer with press fittings, PEX with mechanical fittings. In 80% of cases, the entire intervention (localization + repair + final test) is completed in a 2-3 hour visit. Installation, replacement and repair of electric water heaters. Limescale cleaning, sacrificial anode and heating element. Diagnosis before quoting.

The water hardness in the area is very high. Limescale crystallises in the weakest joints of the installation, especially in elbows and copper connections soldered without specific deoxidiser. We see this mainly in blocks from the 80s-90s in Torrevieja and Punta Prima where the original installations have never been checked. The solution is not just to repair the specific leak; we always recommend checking nearby joints because they tend to be in a similar state. Before opening anything, the plumber performs a three-phase diagnosis. First, a pressure test: all consumption points are closed, and it is checked if the meter continues to turn. If it turns with everything closed, there is a leak in the installation. Second, visual and thermographic inspection with an infrared camera, which detects anomalous cold or hot spots in walls and floors. Third, an acoustic probe to locate the exact point. The most complex case, and one we frequently encounter, is a leak in a pipe embedded in a wall or floor. Without detection equipment, the only way to locate it is to chip away metre by metre until it is found, which damages the structure. With acoustic detection, a professional probe listens for the specific sound of water escaping under pressure and locates it with a margin of error of 30-50 cm. This means we open a 40x40 cm square instead of three metres of wall.

As a professional installation with an invoice, the manufacturer honors their official warranty (2-5 years depending on the brand). We add a 30-day warranty on our labour. The water in the Costa Blanca has an average hardness of 30-40 French degrees. This means that a standard electric water heater of any brand, installed without any special care, lasts between five and eight years before starting to cause serious problems. Compared to an identical water heater installed in soft water areas like Galicia or northern Catalonia, where it can last twelve or fifteen years without issues, the difference is brutal and ultimately impacts your wallet. 30 days on labour and the official manufacturer's warranty on the installed appliance.

The price for water heater and boiler services in El Guinardó typically ranges between 59 and 420 euros. The final figure depends on the property's condition, materials, and labour time. We always provide a fixed quote before starting. Call us, message us on WhatsApp or request your quote online — we respond in less than 10 minutes during business hours. Between 60 and 90 euros depending on the complexity of the installation. If you decide to proceed with the repair afterwards, this amount will be deducted from the repair quote.
