For homes left empty from October to March, the inspection also includes technical shutdown. We close water stopcocks if there is no risk of frost, which is rare on the coast. We purge the water heater if the property is unused for more than three months. We empty the air conditioning trays and turn them off. And we check smoke and carbon monoxide detectors, if present.

Additionally, a visual check of walls and ceilings for moisture stains, new cracks, or signs of leaks that may have appeared during the off-season. In coastal areas, a specific inspection of external balconies and terraces looking 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 water consumption points are closed, and it is checked if the meter is still turning. 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 areas 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 found, which destroys the structure. 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.

As 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. 30 days on labour and the official manufacturer's warranty on the installed appliance. 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 give serious problems. Compared to an identical water heater installed in soft water areas like Galicia or northern Catalonia, where it lasts twelve or fifteen years without issues, the difference is brutal and ultimately impacts finances.

The price for a water heater in Premià de Mar 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. The cost of scheduled maintenance is always less than the accumulated cost of reactive emergencies. The data we collect from our own clients confirms this year after year. For emergencies during business hours, we arrive in less than two and a half hours. For remote properties, up to three hours. 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.
