Another common pattern: leaks that appear the first month after returning to the property after the low season. Pipes that are inactive for months undergo thermal changes, and the pressure when turning the taps back on reveals accumulated weaknesses. If you have left the house closed for four or five months, the first opening should be done slowly while monitoring the water meter. Before opening anything, the plumber performs a three-phase diagnosis. First, pressure test: all consumption points are closed, and it is verified if the meter continues to run. If it runs with everything closed, there is a leak in the installation. Second, visual and thermographic inspection with an infrared camera, which detects abnormal cold or hot spots on walls and floors. Third, acoustic probe to locate the exact spot. The entire localization process takes between 30 and 90 minutes depending on the complexity of the installation. The subsequent repair depends on the type of pipe: soldered copper, pressed multilayer, PER with mechanical fittings. In 80% of cases, the entire intervention (location + repair + final test) is completed in a 2-3 hour visit.

Professional equipment localization: included in the repair cost if you decide to proceed with the repair, €60-90 if you only want the diagnosis. Simple pipe leak repair in visible pipes: €80-160. Repair with controlled opening of wall or floor: €180-380 including plastering and basic finishing. For complex repairs with multiple leaks or pipes requiring full section replacement, a fixed quote after on-site diagnosis. We repair many types of leaks. Visible copper pipes in kitchens and bathrooms. Flexible connections under sinks or basins. Dripping taps at the spindle or cartridge. Stop valves leaking at the gland. Downpipes leaking at the joints. Meters leaking from the main valve. Boilers and water heaters with internal leaks. And poorly insulated community water tanks. The most complex case, and one we handle most often, is a leak in a pipe embedded in a wall or floor. Without detection equipment, the only way to find it is to break open the wall meter by meter, which is very destructive. With acoustic detection, a professional probe listens for the specific sound of water escaping under pressure and locates it within a margin of error of 30-50 cm. This means we open a 40x40 cm square instead of three meters of wall.

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 labour warranty of our own. Oversizing penalises the electricity bill because the appliance uses more energy to maintain the temperature of a volume you never use. Undersizing results in cold showers at the end of the family's morning routine. We calculate your needs before proposing a model. 30 days on labour and the manufacturer's official warranty on the installed appliance.
