Hidden water leak? We'll find it.
Water turning up where it shouldn't — a creeping damp patch, a soggy spot in the garden, a water bill that's crept up with no explanation? Your local Purley crew traces hidden water leaks right across Croydon, Bromley, Sutton and South-East London, using a thermal imaging camera for concealed pipework and a CCTV camera down the drains. We find where it's getting out before anyone starts lifting floors or digging.
You call, we come out, we fix it.

The service
Leak Detection in South-East London
Most hidden leaks fall into two camps, and we carry the right camera for each. For concealed supply and waste pipes — under floors, behind walls, in voids — a thermal imaging camera reads the temperature difference where water is escaping, so we can narrow it down without ripping the place apart. For the drains and underground runs, the CCTV camera goes down the line and shows the crack or displaced joint on screen, pinned to the metre. Either way you see what we've found before anyone talks about a repair — and because we're qualified for both the plumbing and the drainage, the same crew that finds it can fix it. We cover CR, BR, SM and SE, and you get a clear price on the phone first.

Common issues we resolve
If any of these sound like your place, give us a call. Most jobs are sorted on the first visit.
Water bill crept up
Usage up with nothing changed at home — often a leak on a concealed or buried pipe.
The sound of running water
You can hear water moving with the taps off and the stopcock closed.
Soggy or sinking patch outside
A wet, sunken or oddly green patch on the garden, drive or path.
Mould or a musty smell
Persistent damp, mould or a musty whiff with no leak you can actually see.
A drain losing water
A drain leaking somewhere along the run that needs a camera to pin down.

Why call us
What you actually get when you call.
Most "local" drainage sites are national franchises in disguise: a switchboard, a marked-up price, and a stranger off the rota. Call us and you get a straight answer, a fair price up front, and a job we stand behind.
- A real person, every time. No switchboard, no "we'll pass it on". You speak to the engineer who is coming.
- A clear price before we set off. We give you a clear price and an honest ETA on the phone — no surprises on the invoice, no doorstep upsell.
- In writing, up to 5 years. 10 days on unblocks, 30 on CCTV findings, 2 years on plumbing, 5 years on groundworks.
- Certified for the work. WJA for drain jetting, plus IPAF, EUSR and City & Guilds. Most local rivals hold none of these.

Frequently asked
Leak Detection questions, answered.
How do you find a hidden leak?
Two cameras. A thermal imaging camera reads the temperature difference where water's escaping behind walls or under floors, and a CCTV camera goes down the drains and underground runs to show cracks or bad joints on screen — so we pin it down before anyone lifts a floor or digs.
Do you detect gas leaks?
No. We're a drainage and plumbing firm, so we trace water leaks only — supply pipes, waste pipes and drains. If you suspect a gas leak, leave the property and call the National Gas Emergency line on 0800 111 999.
Can you fix the leak once you've found it?
Yes. We're City & Guilds qualified for plumbing and WJA-certified for drainage, so the same crew that traces the leak can repair the pipe or drain, often on the same visit.
What if it's a buried supply pipe?
We'll trace it as far as the thermal camera and the access allow, and show you what we've found. If it turns out to need specialist kit we don't carry, we'll tell you straight rather than guess.
