FAQs

Got a question about leaks or damp? Let us help.

Signs of a leak include:

  • Pooling of water on the ground
  • Cracking of concrete or foundation
  • Damp spots on the floor or the ceiling
  • Sudden drops in water pressure
  • More expensive water bills than usual
  • The sound of running water

If you notice any of the above, contact us, and we’ll aim to get to you within an hour.

There are several reasons why leaks can occur in your home. For example, drastic changes in temperature can cause pipes to crack, whilst old pipes may corrode and rust. Overall, poor installation, poor workmanship, external conditions and even accidents can all contribute to a hidden leak.

You should call a leak detection plumber to investigate where the leak is coming from in your ceiling and the cause of the leak. They will then advise the best route for repairs.

Our repair costs start from £41.25+VAT. The cost of repairing a leak depends on the severity of the leak and the extent of the repairs needed. We charge in 15-minute increments after the initial hour, so you’re only paying for the time needed to resolve the leak.

The duration of a leak detection service will depend on the severity of the leak and how difficult it is to find/access. Heating leaks, on average, take the longest time, taking about half a day to locate and provide a detailed report on.

We have leak-detection services across a range of facilities, including:

  • Leaking central heating pipework or boiler issues
  • Leaking hot or cold water pipes
  • Leaking toilets, sinks, baths or showers
  • Leaking external incoming water supplies
  • Rising damp
  • Ingress of rainwater
