Where Leaks Come From in Newtown
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.


Damp on a party wall
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.
Very old pipework
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.
Finding it before opening up
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.

We provide a clear report of the leak location and recommend the repair approach.
Repair
We carry out the repair — patching, pipe replacement, or relining as appropriate.
Common Questions
Leak Detection in Newtown
There's damp on our party wall. Is it our leak or next door's?
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.
How do I check for a hidden leak in my terrace?
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.
Do you work on heritage terraces in Newtown?
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.
