Leaks in Newtown are shaped by the terraces. The pipework is very old, the houses share walls on both sides, and there is rarely a side path to dig from. A leak can show as damp on the neighbour's side of a party wall before it shows in your own house, and finding it precisely matters before anyone starts opening up a heritage home.

Terraces share walls with the houses either side. A leaking pipe or shower in one house can show as peeling paint or damp skirting next door. Tracing it to the right side of the wall settles whose repair it is.

Many terraces still run old water pipes as well as their original clay sewer. A meter that keeps moving with everything off, or a water bill that climbs for no reason, is the usual first sign of a leak somewhere in it.

Much of Newtown is in heritage conservation areas, and there is no side access. Locating a leak to a small area before anything is cut means less of the house is disturbed and nothing is opened on a guess.

How It Works

01

We discuss your symptoms — high water bills, damp patches, mould — to narrow the search area.

02

We use acoustic listening devices, thermal cameras, moisture readings and, where it suits, tracer dye to pinpoint the leak non-invasively.

03

We provide a clear report of the leak location and recommend the repair approach.

04

We carry out the repair — patching, pipe replacement, or relining as appropriate.

Common Questions

It can be either. We test the water lines and the showers on your side, and trace where the water is coming from, so you know which side of the wall the leak is on before anyone pays for a repair.

Turn off every tap and water-using appliance, read the water meter, and read it again 30 to 60 minutes later without using any water. If it has moved, water is escaping somewhere on your side.

Yes. Repairs to pipes and fixtures do not usually need approval, but changes to how a house looks from the street may, and we tell you upfront if a job needs council approval.
