Water Leak Detection EXPERT

Finding Leaks Without Guesswork

An unexplained rise in your water bill, a damp patch that won’t dry out, or the sound of running water when everything is switched off are all signs of a hidden leak. Rather than lifting floors or opening up walls to search, we use acoustic listening devices, thermal imaging and pressure testing to narrow down the source before any disruptive work starts.

Once we’ve confirmed the leak, we’ll explain what’s involved in the repair and whether it links to your general plumbing or a specific fitting like a hot water cylinder.

Water Leak Detection GUIDE

Signs You May Have a Hidden Leak

Hidden leaks aren’t always obvious. A water bill that’s crept up without any change in usage, a patch of garden that stays green or wet longer than the rest, or a musty smell in one room can all point to water escaping somewhere it shouldn’t. Left alone, even a small leak can undermine flooring, damage plaster and encourage damp and mould over time.

If you notice any of these signs, it’s worth getting it checked before the damage spreads.

COMMON WARNING SIGNS

Don't Ignore These Signs

If any of these sound familiar, it’s worth arranging a leak detection visit before the damage gets worse.

Rising Water Bills

A noticeable increase in your water bill with no change in usage often points to a hidden leak.

Damp Patches or Mould

Patches that won't dry out, or a musty smell in one area, can mean water is escaping nearby.

Sound of Running Water

Hearing water when every tap and appliance is switched off usually means a leak in the pipework.

Low Water Pressure

A sudden or gradual drop in pressure can be caused by water escaping before it reaches the tap.

Warm Patches on Floors

An unusually warm patch on a floor can indicate a leaking underfloor heating pipe or hot water line.

Cracked or Lifting Flooring

Flooring that lifts, cracks or feels soft underfoot can be a sign of water damage from below.

FAQ

Common Questions

We use acoustic listening equipment and thermal imaging to narrow down the location first. In most cases we can pinpoint the leak closely enough that only a small, targeted area needs to be opened up.

A water bill that’s risen without any change in usage, a damp patch that won’t dry, or the sound of running water when nothing is switched on are the most common signs.

A typical visit takes one to two hours depending on the size of the property and how clear the symptoms are. Complex cases involving underground pipework can take longer.

Where possible, yes. If the repair needs parts we don’t carry as standard, or involves opening up a larger area, we’ll agree a return visit and price with you first.

If the leak turns out to be on the water company’s side of the meter rather than your own pipework, we’ll tell you clearly and point you to the right people to contact.
