Additionally, a visual check of walls and ceilings for damp stains, new cracks, or signs of leaks that appeared during the off-season. In coastal areas, a specific check of exterior balconies and terraces for corrosion on railings, deterioration of exterior tiling, and the condition of drains to prevent flooding during intense autumn rains. 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 all points 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 locate the exact point. The most complex case, and the one we resort to most often, 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 meter by meter until it's found, which destroys the work. 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 40x40 cm square instead of three metres of wall.

Being a professional installation with an invoice, the manufacturer respects its official warranty (2-5 years depending on the brand). We add our 30-day warranty on labour. 30 days on labour and the manufacturer's official warranty on the installed appliance. The water in 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 give serious problems. Compared to an identical heater installed in soft water areas like Galicia or northern Catalonia, where it lasts twelve to fifteen years without problems, the difference is brutal and ultimately impacts the wallet.

The price for water heater services in Cornellà de Llobregat typically ranges between 59 and 420 euros. The final figure depends on the condition of the property, materials, and work time.

For night-time and holidays, a maximum of three and a half hours. For renovations, we schedule a technical visit with a detailed quote and planning that respects the client's calendar.
