Leak Detection in Croydon

Let’s Fix Group Ltd, led by David Prince, traces hidden water leaks in Croydon homes and flats using non-invasive methods, then repairs what’s found. Call today and one of our expert engineers will be out to you quickly.

David Prince has spent over 20 years tracing London’s leaks, and that experience is exactly what a hidden leak in a Croydon home needs: the source found first, the floor left intact.

Let’s Fix Group Ltd is Gas Safe registered and fully insured, using its own engineers rather than subcontractors across everything from leak detection to blocked drain services Croydon households call us out for.

Call Let’s Fix Group Ltd today and we’ll arrange a leak detection visit in Croydon.

Leak detection is the work of finding exactly where water is escaping, without ripping up your home to get there. It’s a survey first and a repair second.

What Leak Detection Covers

Most people call us because something doesn’t add up. A damp patch on a hallway wall, a boiler that keeps losing pressure, or a water bill that’s jumped for no reason. We’ve seen all three across Croydon, and they rarely announce themselves clearly.

Our leak detection work covers concealed pipework under floors, behind plaster, inside stud walls and beneath solid screed. It also covers heating circuits, mains supply pipes, cylinders and drainage runs. If water is going somewhere it shouldn’t, that’s our job to find.

• Hidden leaks under timber floors, tiles and concrete screed
• Central heating pressure loss and unexplained top-ups
• Damp patches, staining and water ingress on walls and ceilings
• Mains supply leaks between the stopcock and the property
• Flat-by-flat diagnosis in converted and purpose-built blocks

David Prince heads a team of expert engineers working across London and the South East, and they’re the firm’s own people, never subcontractors. Once the source is confirmed, we can carry out the repair too, and if the fault turns out to sit with an old cylinder or a tired boiler, we handle installation as well as repair.

Emergency and 24/7 Callout Support in Croydon

Water doesn’t wait, so neither do we. Around 90% of repairs are sorted the same day, and where a leak is actively damaging a property we treat it as an emergency and get someone moving. If you’re searching for water leak detection near you in Norbury, Thornton Heath or South Croydon, there are engineers covering those areas already.

That local spread matters more than it sounds. A converted Victorian terrace off London Road and a purpose-built flat near East Croydon need very different approaches. Access, shared risers and neighbouring properties all change how we work. Our engineers know the housing here, because it’s the housing they work in every week.

We’ll isolate the water where we need to, protect floors and furniture, and leave your home as we found it. No mess left behind, no vague promise to come back another day.

How the Investigation Works

Wondering whether we’ll have to open up your walls to find it? Almost never, because the whole point of the survey is to pinpoint the leak before anything is disturbed.

We start with the simple things: pressure testing, isolating circuits, checking the meter and reading moisture levels. From there we bring in non-invasive methods. Thermal imaging shows temperature differences behind surfaces. Acoustic listening picks up escaping water under screed and paving. Tracer gas testing traces the exact exit point on stubborn pipework. Where drainage is the suspect, camera and sonar surveys follow the pipe run underground.

Only when the location is confirmed do we open anything, and then it’s the smallest opening that does the job. Homes near Lloyd Park often have root intrusion in their drains, so a drainage survey earns its place there. Whether you need leak detection in Croydon or a cctv drain survey in Croydon, we cover the whole area.

You get a plain explanation of what we found, where it is, and what fixing it involves. No jargon, no guesswork.

Insurance and Trace-and-Access Claims

Here’s the part that worries people most: paying for a survey and getting nowhere. So it’s worth being clear about what’s included. The investigation covers the diagnostic work, the equipment, the engineer’s time on site and a written explanation of the findings. It’s done in-house by our own engineers, not passed to a third party who then bills you separately.

Many home insurance policies include trace and access, which is the cover for finding a leak and getting to it. We write our findings up so you can put them in front of your insurer without arguing over what was done. If the claim covers reinstatement, we’ll set out clearly what the repair and making good involves.

The quote settles the rest. You’ll know what the work covers before anyone starts, with fixed pricing and no call-out surprises. Whether you need leak detection in Croydon or hot water cylinder replacement services Croydon homeowners rely on, we cover the whole area, and everything we install carries a 10-year guarantee. We’re Gas Safe registered and fully insured, and where the leak sits on a gas appliance that registration isn’t optional, as the Gas Safe Register makes plain.

Common Signs of a Hidden Leak

Some leaks shout. Most whisper for months first. If any of the following sounds familiar, don’t sit on it, because water damage compounds quickly in older brickwork and converted flats.

• Damp or discoloured patches that don’t dry out
• A boiler needing repressurising every few weeks
• Warm spots on a floor where no pipe should run
• Musty smells in a cupboard, hallway or under stairs
• A water bill rising with no change in usage
• Sounds of running water when every tap is off
• Blown plaster, lifting tiles or cracked grout

A damp patch isn’t automatically a leak. Condensation tends to spread evenly across cold surfaces and eases when a room is ventilated. A leak stays put, stays wet, and often gets worse. Moisture readings tell us which one you’ve got in minutes.

With over 20 years’ experience behind the team, David and his engineers have traced leaks in Purley semis, Addiscombe terraces and Waddon flats, and our water leak detection services cover the whole borough. Call us and we’ll get someone out to you quickly.
