Hidden leaks behind walls, under floors or below the slab can waste water and cause serious damage before you ever see a puddle. We use non-invasive detection methods to find the source quickly, without unnecessary digging or damage to your home.

Water Leak Detection EXPERT
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
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
If any of these sound familiar, it’s worth arranging a leak detection visit before the damage gets worse.
A noticeable increase in your water bill with no change in usage often points to a hidden leak.
Patches that won't dry out, or a musty smell in one area, can mean water is escaping nearby.
Hearing water when every tap and appliance is switched off usually means a leak in the pipework.
A sudden or gradual drop in pressure can be caused by water escaping before it reaches the tap.
An unusually warm patch on a floor can indicate a leaking underfloor heating pipe or hot water line.
Flooring that lifts, cracks or feels soft underfoot can be a sign of water damage from below.

I recently had my boiler serviced by Heatgap( 99 Byron Road,Luton) and I couldn’t be happier with the experience. The Technician arrived on time, was professional, and explained everything clearly. The service was thorough, and they made sure the boiler was running safely and efficiently before leaving. What really stood out was their friendly attitude and attention to detail. They took the time to answer my questions and gave helpful advice on maintaining the boiler. Overall, excellent service from start to finish. I would definitely recommend Heatgap to anyone looking for reliable and professional boiler servicing.

FAQ
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.
Rising water bills or a damp patch that won’t dry out are worth checking sooner rather than later. Get in touch for a fast, honest assessment.
