“The plumbers were prompt, courteous and highly skilled. They replaced the tap and installed the new shower screen with great precision, making sure everything fit perfectly. They also took the time to explain the features and maintenance tips, which was a nice touch. The bathroom looks amazing, and everything works perfectly. I highly recommend them for any bathroom upgrades!”

“Outstanding service! They recently replaced our old toilet, and I couldn't be more satisfied. The team was on time, extremely knowledgeable, and handled the entire process seamlessly. They made sure everything was installed perfectly, and even cleaned up afterwards. The new toilet works flawlessly, and the attention to detail was impressive. If you need a toilet replaced, I highly recommend them for a hassle-free experience!”

Nothing gets opened until we know where
Lifting a floor to hunt for a leak turns a small job into a big one. We pinpoint it with acoustic and thermal equipment, show you exactly where it is, and price the repair from there.
-
The leak is rarely under the damp patch
Water runs along joists, pipes and plaster before it shows. The stain marks where it surfaced, not where it started. That’s why digging under it so often turns up nothing.
-
Check your meter first
Turn off every tap and watch the water meter for ten minutes. Still ticking over? Something on your side is leaking. Tell us when you ring — it narrows the search straight away.
-
Boiler losing pressure? That’s a leak too
If you’re topping up the heating every few weeks, water is escaping somewhere, often under a floor. We investigate it the same way, and it’s best done before the pipes corrode further.

-
Tell us what you’ve noticed
Damp, a ceiling stain, a higher bill, or a boiler dropping pressure. Photos help most of all.
-
Traced and priced
Your engineer finds the source with non-invasive kit and shows you what’s there. Then we price the repair before starting it.
-

Things people ask us
Will my floor need digging up?
Not to find the leak. Our acoustic and thermal kit locates it without damage, so we only open up what the repair really needs.
What does leak detection cost?
Ring us and tell us what you’re seeing. You’ll get a price for the investigation before booking, then a separate price for the repair once we know the cause.
My bill’s gone up but I can’t see a leak. Can you help?
Yes — it’s one of the most common reasons people ring us. A rise in usage with no explanation usually points to a supply-side leak, and we can trace it without digging.
Will you fix it once you’ve found it?
Yes. We find the leak and repair it too, so there’s no second trade to arrange.
