When water is leaking somewhere inside your walls or under your floors, guessing where it is means unnecessary damage and expense. Rip up the wrong floorboard and you've destroyed your floor for nothing. That's where thermal imaging comes in. Our cameras detect temperature differences caused by escaping water, cold water shows as a cooler patch, hot water from heating pipes shows warmer Common across Chatham, from Railway Street to Rochester High Street.

We can trace leaks through walls, under floors, and in ceilings without drilling a single hole. It's particularly useful in Chatham's older properties around Strood and Rochester where pipe routes aren't documented.

Thermal imaging isn't magic, but it's close. The camera shows us exactly where water is pooling or running. We cross-reference that with pressure testing on your plumbing or heating systems to confirm which pipe is leaking. Only then do we make a small, precise access hole to expose and repair the leak.

When You Need Thermal Imaging

⚠️

Damp patches with no obvious source

You've got a damp patch on the ceiling or wall but can't see where it's coming from. The leak could be metres away, with water running along joists or behind plasterboard before appearing.

⚠️

Rising water bills

Your meter is spinning with everything turned off. There's a leak somewhere but you've checked all visible pipes and found nothing. It's hidden behind something, and thermal imaging will find it.

⚠️

Boiler pressure dropping

The heating system is losing pressure but there are no visible leaks. It's escaping somewhere in the underfloor pipework or behind walls. Thermal imaging shows us where the hot water is leaking.

⚠️

Musty smell but no visible mould

That damp smell means water has been sitting somewhere long enough for mould to grow. Even if you can't see it, the thermal camera will show the moisture behind the surface.

⚠️

Water damage after finding and fixing a leak

You fixed one leak but the damage is worse than expected. There might be a second leak nearby. Thermal imaging sweeps the area to check for additional hidden leaks before you repair the damage.

How Thermal Imaging Works

Thermal cameras detect infrared radiation (heat). Water conducts heat differently than air or building materials, creating temperature variations we can see on screen:

Cold water leaks show cooler

Cold water escaping from mains pipes or supply lines creates a cooler patch on walls or floors. The camera shows this as a blue or darker area compared to the surrounding dry material.

Hot water leaks show warmer

Leaks from central heating pipes show up as warmer patches. This is especially useful for underfloor heating leaks, the hot water creates a clear hotspot on the floor surface.

Evaporation creates cooling

Even slow leaks cause evaporative cooling. The wet area is slightly cooler than the dry area around it due to evaporation. The camera picks this up even if the leak itself is tiny.

We scan methodically

We scan walls, floors, and ceilings in the affected area and trace the temperature anomaly back to its source. We cross-check with your plumbing layout and pressure tests to confirm.

Limitations

Thermal imaging works best on surface leaks or those just behind a single layer. Very deep leaks (through multiple floors) or leaks behind thick insulation are harder to detect. In those cases, we combine thermal imaging with acoustic listening.

Our Leak Detection Process

We use multiple techniques to locate leaks accurately. Here's how we work:

1

Visual inspection first

We check all obvious places, under sinks, around radiators, near the boiler. Many leaks are visible once you know where to look. If we find it visually, we skip the thermal imaging.

2

Pressure test the systems

We isolate sections of your plumbing or heating and test each for pressure loss. This tells us which circuit the leak is on, hot water, cold water, or heating.

3

Thermal scan the area

We scan the affected area with the thermal camera, looking for temperature anomalies. We mark the coldest or warmest spot, which is usually where the leak is.

4

Acoustic listening (if needed)

For deep or hard-to-detect leaks, we use acoustic listening equipment to hear water escaping under pressure. Combined with thermal imaging, this pinpoints even the most elusive leaks.

5

Expose and repair

Once we're confident we've found it, we make a small access hole, confirm the leak, and repair it properly. We test under full pressure before sealing up.

Leaks We Find with Thermal Imaging

Thermal imaging is particularly effective for these types of leaks in Chatham homes:

Central heating pipe leaks

Hot water from heating pipes creates clear thermal signatures under floors and in walls. We can trace the entire run of a pipe and see exactly where it's leaking.

Underfloor heating leaks

These are notoriously difficult to locate without thermal imaging. The leaking section shows as a hotspot on the floor surface. We can pinpoint it to within a few inches.

Shower and bath leaks

Water escaping through failed grout or sealant shows up clearly on the ceiling below or the wall behind. We see the extent of the moisture spread and locate the entry point.

Roof leaks

Water pooling in ceiling voids from roof leaks shows as cold patches on the ceiling. We can trace where it's coming in even if the visible stain is far from the actual leak point.

Hidden pipe runs

If your plumbing layout isn't documented, thermal imaging shows us where the pipes actually are. This is invaluable when planning access to repair a leak without damaging unrelated areas.

Common Questions

Got questions? Here's the quick answers.

How much does thermal imaging leak detection cost in Chatham?

Thermal imaging leak detection costs £120-£200 for a full survey across Chatham and surrounding areas. If we find and repair the leak on the same visit, we often waive the detection fee, you just pay £180-£400 for the combined service depending on the repair complexity.

How long does thermal leak detection take?

Scanning and locating a hidden leak takes 1-3 hours depending on the size of the area and how elusive the leak is. Once found, most repairs take another within 2 hours. Expect a half-day visit for detection and repair combined, whether you're in Rochester High Street, Walderslade, or Railway Street.

Can thermal imaging find any leak?

It's very effective for leaks that create temperature differences, hot heating leaks, cold mains leaks, and moisture from slow drips. Very deep leaks through multiple floors or behind thick insulation are harder. We combine it with pressure testing and acoustic listening for complete coverage We cover all Chatham areas including ME4, ME1, and ME7 postcodes.

Will you have to damage my walls to find the leak?

Thermal imaging is non-invasive, no drilling or damage to locate the leak. Only once we've pinpointed it do we make a small, precise access hole to expose the pipe and repair it. Far less damage than exploratory searches We cover all Chatham areas including ME4, ME1, and ME7 postcodes.

My heating is losing pressure, can thermal imaging find it?

Yes, leaking heating pipes show up clearly as warm spots on floors or walls. We'll scan the system, locate the leak, and repair it. Most central heating leaks are under floors or behind radiators, thermal imaging finds them quickly We cover all Chatham areas including ME4, ME1, and ME7 postcodes.

Can you detect leaks behind tiles?

Yes, thermal imaging works through tiles. Moisture behind tiles creates a different thermal signature to dry areas. We can see where water is escaping through failed grout or sealant without removing tiles We cover all Chatham areas including ME4, ME1, and ME7 postcodes.

What if you can't find the leak with thermal imaging?

We combine thermal imaging with pressure testing and acoustic listening. This triple approach finds virtually all leaks. If it's genuinely undetectable (very rare), we'll discuss exploratory options or refer to specialist leak detection companies with ground-penetrating radar We cover all Chatham areas including ME4, ME1, and ME7 postcodes.

Is the thermal camera safe around electrics and pipes?

Yes, thermal cameras are completely non-contact. They just detect infrared radiation, no electricity, no radiation emitted. Safe to use around all household systems We cover all Chatham areas including ME4, ME1, and ME7 postcodes.
