Water Leak Repair in Cascais

In Cascais the leak that costs the most is usually the one nobody is standing next to. Houses in Birre, Quinta da Marinha, Manique and out towards Guincho have long supply runs buried between the meter box at the gate and the building, irrigation circuits threaded through the garden and, very often, a pool with an automatic top-up. Water can escape from any of them for weeks without a mark on a wall. Add owners who are abroad for part of the year and the loss goes unnoticed until a bill arrives. We work across Cascais on leak detection and repair, Monday to Saturday from 9am to 8pm.

About our service in Cascais

A pool is where a garden leak hides best. If the level drops and the automatic filler simply tops it up, the meter keeps turning and nothing looks wrong; a crack in the shell, a failed skimmer seal or a weeping return line all look identical from the terrace. The test is unglamorous and effective: turn the top-up off, mark the water line and compare it against a bucket of pool water standing on the step, so evaporation affects both equally. If the pool falls faster than the bucket, it is losing water and not simply drying in the sun. The buried supply line is the other big one. In these properties the run from the meter to the house can be long, laid years ago, sometimes crossing under a drive or a paved terrace. When it splits, the water sinks straight into sandy ground and the only clues are a meter that never stops, a drop in pressure indoors and, occasionally, one patch of lawn that stays green when everything else has burnt. We trace the line before we dig, so the excavation is as small as it can reasonably be, and we tell you honestly when ground conditions make the location approximate rather than exact. For houses that stand empty part of the year, the single most useful habit is to close the mains valve at the meter box when you leave and open a tap to drain down. A hose that fails in an empty house runs until somebody notices. If you are away and a caretaker or neighbour reports water, we can work from photographs and meter readings sent over WhatsApp and report back the same way. We are out in Cascais Monday to Saturday, 9am to 8pm, and closed on Sunday, with priority given to leaks that are actively soaking a building. The quote depends on the length of the run, the surface above it and how much has to be lifted, and there is no obligation attached to it.

Frequently Asked Questions

Questions from Cascais homeowners:

My pool level keeps dropping. Is that a leak or evaporation?

Compare the pool with a bucket of pool water left on a step, both exposed to the same sun, with the automatic top-up switched off. If the pool drops faster than the bucket over a couple of days, water is being lost. We then test the circuit, the skimmers and the returns to find where.

I am not in Portugal for most of the year. How do we handle a leak?

We arrange access with whoever holds the keys and send photographs at each stage, including the meter before and after. If you are considering leaving the property empty again, we can show your caretaker how to isolate and drain the system so a failed fitting cannot run for weeks.

Will you have to dig up the whole garden?

No. We trace the line and narrow the search before anything is lifted, so the excavation is limited to the section that matters. On old buried pipe in sandy ground we will tell you if the location is approximate, and we open one point to confirm before going further.
