Another common scenario: leaks that appear in the first month after returning to the property after the low season. Pipes that have been inactive for months undergo thermal changes, and the pressure when turning the taps back on reveals accumulated weaknesses. If you've left the house closed for four or five months, the initial opening should be done slowly while monitoring the meter. Before opening anything, the plumber carries out a three-stage diagnosis. First, a pressure test: all water outlets are closed, and we check if the meter is still running. If it runs with everything closed, there's a leak in the system. Second, a visual and thermographic inspection with an infrared camera, which detects abnormal cold or hot areas in walls and floors. Third, an acoustic probe to locate the exact spot. The entire detection process takes between 30 and 90 minutes, depending on the complexity of the installation. The subsequent repair depends on the type of pipe: copper with solder, multilayer with press fittings, or PEX with mechanical fittings. In 80% of cases, the entire job (detection + repair + final test) is completed in a single 2-3 hour visit.

Professional equipment leak detection: included in the repair cost if you proceed with the repair, or €60-€90 if you only want the diagnosis. Simple leak repair on exposed pipework: €80-€160. Repair involving controlled opening of a wall or floor: €180-€380, including plaster filling and basic finishing. For complex repairs with multiple leaks or pipework requiring complete section replacement, a fixed quote will be provided after an on-site diagnosis. We repair many types of leaks. Exposed copper pipes in kitchens and bathrooms. Flexible connections under sinks. Dripping taps at the spindle or cartridge. Stop valves leaking at the gland. Waste pipes leaking at the joints. Meters leaking at the stopcock. Boilers and water heaters with internal leaks. And poorly insulated communal water tanks. The most complex case, and one we deal with often, is a leak in a pipe embedded in a wall or floor. Without detection equipment, the only way to find it is by chipping away metre by metre 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 within 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 respects 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 power to keep a volume hot that you never use. Undersizing leads to 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 official manufacturer's warranty on the installed appliance.
