CM13 · CM14 · CM15Leak Detection in Brentwood
A hidden leak doesn't announce itself — it shows up as a creeping water bill, a damp patch that comes and goes, or boiler pressure that keeps dropping. We trace the source through walls, floors and solid slabs without ripping the place apart on a guess.
Finding what you can't see.
Most hidden leaks in Brentwood homes aren't dramatic — they're slow. Water tracks along a pipe run, soaks into a screed or a wall, and surfaces somewhere completely different from where it's actually escaping. Chasing that by eye means lifting floors and opening walls in the wrong places, doing more damage than the leak itself.
We do it the other way round — diagnose first, dig last. Pressure-testing isolates the affected section, acoustic listening pinpoints the escape under solid floors, and moisture meters confirm exactly where the water's sitting before a single tile comes up. The result is a small, deliberate opening instead of a wrecked room. No call-out fee inside our area, a fixed quote before work starts, every repair covered by a 12-month labour guarantee, and findings documented for an insurance claim where it's relevant.

How we find a leak.
A staged approach — narrow it down with diagnostics, then take the smallest possible access.
- System pressure-test to isolate the affected section
- Acoustic listening to pinpoint leaks under solid floors
- Moisture meters to map exactly where water is sitting
- Tracer dye for waste, soil and toilet leaks
- Minimum-damage access — one tile, one section of board
- Repair the leak, documented for your insurer if claimable
Signs you have a hidden leak
- Water bill suddenly up with no change in usage
- Damp patch on a ceiling or wall that comes and goes
- Boiler pressure dropping every few days for no obvious reason
- Warm spot on a floor — often a leaking heating pipe in the screed
- Mould returning despite cleaning
- The sound of running water with everything turned off
Why Brentwood housing hides leaks.
Brentwood's housing stock is a real mix, and each type hides leaks differently. The town is full of 1930s–60s detached and semi-detached homes — through Warley, Hutton Mount and the Doddinghurst Road area — that have nearly all gained a kitchen-diner or rear extension at some point. Those extensions almost always sit on a solid concrete slab, with heating and supply pipes buried in the screed. When one of those pipes weeps, there's no void to inspect: the only clue is a warm patch underfoot or pressure that won't hold.
The newer estates off Doddinghurst Road and around Pilgrims Hatch bring their own pattern — plastic push-fit and manifold systems where a single fitting under a floor can drip unseen for months. Older Warley terraces hide the opposite problem: tired copper and the odd surviving lead run. Pressure-drop diagnosis and acoustic detection work across all of them, which is exactly why we lead with the kit rather than the crowbar — across CM13, CM14 and CM15 alike.

Quick answers before you call.
How do you find a leak without digging the whole floor up?
We diagnose before we dig. Pressure-testing tells us which section is leaking, acoustic listening pinpoints the escape under a solid floor, and a moisture meter confirms where the water's sitting. By the time anything comes up, it's a small, deliberate opening — not a wrecked room.
My boiler pressure keeps dropping — is that a hidden leak?
Often, yes. If there's no visible drip and the pressure-relief pipe outside is dry, the loss is usually a small leak somewhere in the heating circuit — frequently a pipe buried in a solid floor. That's exactly what acoustic detection and pressure testing are for.
Can you find leaks under a solid-floor extension?
Yes — that's one of the most common jobs in Brentwood. Extensions built on a concrete slab have pipes set in the screed with no void to inspect, so we rely on acoustic listening and moisture mapping to locate the leak precisely before lifting anything.
Will you provide evidence for an insurance claim?
Where the leak is likely to be claimable, we document the detection findings and the repair so you have what your insurer needs. Many home policies cover "trace and access", and clear records make that far smoother.
Is there a call-out fee for leak detection in Brentwood?
No call-out fee inside our coverage area, which covers CM13, CM14 and CM15. You get a fixed quote before any detection or repair work begins, and the labour carries a 12-month guarantee.
Damp patch? Bill creeping up?
Let's find it before it spreads.
Describe what you're seeing — the damp, the pressure drop, the bill — and we'll tell you what's likely going on and how we'd trace it with the least disruption.
