Find the leak. Keep the doors open.
Hidden leaks under shop floors, fit-outs and car parks, pinpointed without digging, so the store keeps trading.
Why retailers use us.
A leak in a shop is a stock problem, a safety problem and a footfall problem all at once. Our methods are non-invasive, so there is usually nothing to dig up or cordon off.
Nothing lifted on a hunch
Thermal, acoustic and tracer-gas kit finds the source through tiles, concrete and fitted joinery. Any opening-up is small, deliberate and in the right place.
Same-day find and repair
We aim to find and repair the leak on the same visit wherever the job allows, so one leak does not turn into a week of buckets and warning signs.
One supplier, every branch
Engineers based across England, Scotland and Wales. Property and facilities teams get one number, one report format and one invoice for the whole estate.
Reports insurers accept
Every investigation ends with a written report and thermal images, ready for your insurer or loss adjuster on a trace-and-access claim.
Leaks we find in retail premises.
From a slow supply-pipe leak inflating the water bill to a ceiling drip from the unit upstairs. If water is going where it shouldn’t, we can find where it starts.
Water mains & underground
Supply pipes under car parks, service yards and slab floors. The usual suspect behind a water bill that has quietly doubled.
Find out moreHeating & pipework
Commercial central heating and underfloor systems losing pressure. Tracer gas and thermal imaging find the break with the floor still in place.
Find out moreRoof & ceiling leaks
Flat roofs, rooflights, box gutters and drips from the unit above. We trace the water back to where it gets in, which is rarely where it shows up.
Find out moreUnder-floor & slab
Pipes buried in screed beneath tiles, vinyl and timber. Located from above, so the shop floor stays whole.
Find out moreWashrooms & staff areas
Customer toilets, staff kitchens and cleaners’ cupboards. Small rooms with a lot of pipework, and the source of most damp patches next door.
Find out moreDrains & CCTV surveys
Blocked, cracked or leaking drains in service yards and beneath units, surveyed with CCTV drain cameras and pressure testing.
Find out moreDamp & structural ingress
Penetrating damp, basement stock rooms and party walls. Moisture mapping shows what is a leak and what is condensation.

Insurance claimsHow a survey works.
Four steps from the first phone call to a marked-up floor and a report in your inbox.
Call us
Tell us what you have seen: a damp patch, a pressure drop, a bill that jumped. We match the right engineer and kit to the job and agree a time for the visit.
Engineer on site
A qualified leak engineer arrives with thermal imaging, acoustic sensors, tracer gas and correlators in the van. Every engineer has at least ten years’ experience.
Non-invasive survey
We test, listen and scan until the evidence points to one spot. Water, heating or drainage, above ground or below, with the floor and fit-out left alone.
Pinpointed and reported
You get the exact location, thermal images and a written report for your insurer. Where the repair is straightforward we aim to complete it on the same visit.

See the full processThe equipment we use.
Leak detection is a question of evidence. We bring every method to every job, so the answer comes from agreement between them rather than a guess from one.
Thermal imaging cameras
Show the temperature difference a hot-water or heating leak leaves in tiles, plaster and screed.
Acoustic listening & ground mics
Hear pressurised water escaping beneath concrete, tarmac and block paving.
Tracer gas detection
A safe hydrogen and nitrogen mix put through the pipe escapes at the break and is picked up at the surface.
Leak correlators
Two sensors on a water main calculate the position of the leak between them.
Borescope cameras
See inside voids, ducts and behind fitted units through a hole the size of a coin.
Moisture meters
Map how far the water has travelled and separate a leak from condensation.
CCTV drain cameras
Survey drains, gullies and interceptors from the inside.
Pressure testing
Confirm which circuit is losing water before anyone starts looking for it.
Drone roof inspection
Survey large flat roofs and rooflights without scaffolding or a cherry picker.
Retail premises we work in.
Every retail format has its own way of hiding a leak. We have seen most of them.
Supermarkets & grocery
Chillers, condensate lines and busy back-of-house plumbing on a floor that never really closes.
View sectorShopping centres
Multi-tenant leaks, service corridors and units stacked above units.
View sectorRetail parks
Long supply runs under car parks and shared service yards, often unmapped.
View sectorHigh-street shops
Older buildings, shared walls and fit-outs that hide the pipework.
View sectorForecourts & convenience
Water supply and car-wash feeds beneath the hardstanding, found without breaking it up.
View sectorCar showrooms
Big slab floors, valet bays and glass frontages that show every damp patch.
View sectorRestaurants & cafés
Kitchens, cellars and the ceiling of the customer downstairs.
View sectorFacilities & property teams
One supplier for the whole portfolio, with the same report format on every site.

What we found at a few of the shops and salons we have visited recently.
Shop water main: two leaks found and repaired
Water was escaping from the external supply. We found two leak points, replaced the section of main and the stopcock, and the retest passed.
Hairdresser: ceiling leak traced to the flat above
Water was coming through the salon ceiling. Dye tests traced it to a cracked bath waste in the flat upstairs.
Salon: rising water bill traced to a toilet valve
The bill had gone up and the meter never stopped. The cause was a toilet float valve, which we isolated so the meter stopped.

The things store, property and facilities managers ask us most.
Will we have to close the shop?
Rarely. Surveys are non-invasive, so there is usually no digging or floor-lifting to cordon off, and in most cases the shop can keep trading while we work.
How do you find a leak under the floor without lifting it?
By combining methods. Thermal imaging shows the temperature change from a hot pipe, acoustic sensors hear water escaping under pressure, and tracer gas rises through concrete and tile to a detector on the surface. When the methods agree, we mark the spot.
How quickly can an engineer attend?
We have engineers based across England, Scotland and Wales, so we can usually get to you fast. We aim to find and repair the leak on the same day wherever the job allows. Call 0333 567 2615 for availability in your area.
Do you repair the leak as well?
Yes. Where the repair is straightforward we aim to complete it on the same visit. For anything bigger, you get the exact location and a report so your own contractor can go straight to it.
Will the report be accepted by our insurer?
Our reports are written for insurance claims: the cause, the location, thermal images and what was done. Businesses and loss adjusters use them for trace-and-access claims.
Can you cover all our branches?
Yes. With 25 engineers nationwide we look after single kiosks and whole estates. Facilities and property teams get one number and the same report format on every site.
Are you accredited and insured?
We carry £5 million public liability insurance and are accredited by CIPHE, WIAPS, WaterSafe and SPATA. Every engineer has at least ten years’ leak detection experience.
