What We Handle Immediately

Leaks need fast action. Some are obvious, like water through a ceiling. Others hide behind tiles, under floors, inside boxing or in shared risers until the damage becomes visible.

  • Burst pipes and leaking joints
  • Hidden leaks behind walls or under floors
  • Ceiling leaks from bathrooms above
  • Central heating pipe leaks
  • Boiler pressure loss caused by pipework leaks
  • Trace and access support for insurance claims
  • Leaks in flats, conversions and mansion blocks
  • Stopcock issues and emergency isolation

Signs You May Need Leak Detection

Call before opening walls or lifting floors if the source is not obvious. A targeted check can save time, limit damage and make the repair easier to explain to insurers, landlords or managing agents.

  • Damp patches growing on ceilings, walls or skirting boards
  • Boiler pressure dropping even after topping up
  • A musty smell, swollen flooring or staining with no visible leak
  • Water meter movement when taps and appliances are off
  • Leaks affecting a flat below, neighbour or shared building area

How We Find the Leak

We start with the least disruptive checks first. The aim is to narrow down the source before opening up walls, floors or boxing.

1

Make Safe

We isolate the water where possible and protect the affected area.

2

Trace The Source

We check pressure, pipe routes, fittings, bathrooms, heating circuits, visible damp patterns and likely access points.

3

Explain Access

If access is needed, we explain exactly where and why before cutting anything open.

4

Repair And Test

We repair the failed pipe or fitting, then test the system before leaving.

What To Do Before We Arrive

  • Turn off your stopcock if water is escaping quickly
  • Switch off electrics if water is near sockets, lights or the consumer unit
  • Move furniture and valuables away from the leak
  • Take photos for your insurer if there is visible damage
  • Call 07855 744889 and describe where the water is appearing

Leak Detection Questions

Can you fix a burst pipe the same day?

In most cases, yes. We carry common fittings and repair materials so urgent pipe repairs can often be completed on the first visit.

Can you help if my boiler pressure keeps dropping?

Yes. A pressure drop can be caused by a boiler fault, radiator valve, pipework leak or hidden central heating leak. We check the obvious causes first and then advise the next step.

Do you provide trace and access leak help?

Yes. We can help trace the source, explain where access is needed and carry out plumbing repairs. If you are speaking with an insurer, take photos and keep notes from the visit.

Can you help with leaks in shared pipework?

Yes. We work with shared risers, communal pipework and managed blocks. We can also speak with building managers where access is needed.

Will you need to damage walls or floors?

Only if it is necessary. We look for the most targeted access point and explain it before any opening-up work starts.
