The entire localisation process takes between 30 and 90 minutes, depending on the complexity of the installation. Subsequent repair depends on the type of pipe: copper with solder, multilayer with press fittings, PER with mechanical fittings. In 80% of cases, the entire intervention (localisation + repair + final test) is completed in a 2-3 hour visit. Another common pattern: leaks appearing in the first month after returning to the property following 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. 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.

The most complex and common case we 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 a metre at a time until it's found, which causes significant damage. With acoustic detection, a professional probe listens for the specific sound of water escaping under pressure and locates it with an error margin of 30-50 cm. This means we open a 40×40 cm square instead of three metres of wall. Before opening anything, the plumber performs a three-phase diagnosis. First, a pressure test: all consumption points are closed, and it's checked if the meter is still turning. If it turns with everything closed, there's a leak in the installation. Second, visual and thermographic inspection with an infrared camera, which detects anomalous cold or hot areas in walls and floors. Third, an acoustic probe to pinpoint the exact location. Localisation with professional equipment: included in the repair cost if you decide to proceed with the repair, 60-90 euros if you only want the diagnosis. Repair of a simple leak in an exposed pipe: 80-160 euros. Repair with controlled opening of a wall or floor: 180-380 euros, including plastering and basic finishing. For complex repairs with multiple leaks or piping requiring complete section replacement, a fixed quote will be provided after an on-site diagnosis.

As it is a professional installation with an invoice, the manufacturer honours its 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 special care, lasts between five and eight years before starting to cause serious problems. Compared to an identical heater installed in soft water areas like Galicia or northern Catalonia, where it can last twelve or fifteen years without issues, the difference is significant and ultimately impacts your wallet. 30 days on labour and the manufacturer's official warranty on the installed appliance.

The price for water heater installation and repair in Sant Cugat del Vallès typically ranges between 59 and 420 euros. The final figure depends on the condition of the property, materials, and working time. We always provide a fixed quote before starting. Yes, a 30-day guarantee on the repaired part. If the leak reappears at the same spot within that period, we return at no extra cost.
