Commercial properties we work in
A leak in a commercial building costs more than water. It can close a floor, spoil stock or put a kitchen out of action. We work across all kinds of sites in London.
- Offices and co-working spaces
- Shops and retail units
- Restaurants, cafés and commercial kitchens
- Hotels, guest houses and short lets
- Schools, nurseries and colleges
- Blocks of flats and communal areas
- Warehouses and light industrial units
- Surgeries, clinics and care homes
- Gyms, salons and leisure sites
- Landlords, letting agents and managing agents
How we find leaks on commercial sites
Bigger buildings mean longer pipe runs, more floors and more people affected. We narrow the search down fast, then pinpoint the leak before anything is opened.
Pressure testing by zone
Floors, risers and circuits are isolated and tested one at a time, so we know which part of the building is losing water without shutting the whole site down.
- Heating, hot and cold water
- One zone at a time
- Proves the repair afterwards
Thermal imaging
Heating and hot water leaks show up as warm patches through walls, floors and ceiling voids, so we can trace them without lifting floors or taking ceilings down.
- Heating and hot water
- Underfloor heating
- Ceiling and floor voids
Acoustic tracing
Ground microphones pick up the sound of water escaping under pressure through concrete, paving and car parks, including on long underground supply pipes.
- Underground mains
- Car parks and yards
- Solid concrete floors
Tracer gas
For leaks too small or too deep for other methods. The pipe is filled with a safe hydrogen and nitrogen mix that escapes at the leak and is picked up at the surface.
- Pinpoints the smallest leaks
- Long and buried pipe runs
- Safe, non-toxic gas
Moisture mapping
Readings across walls, floors and ceilings show how far the water has spread and where it is coming from, which is especially useful where one unit leaks into another.
- Leaks between units and floors
- Stained ceiling tiles
- Shows when it has dried out
Inspection cameras
A camera on a flexible cable goes into risers, boxing, ceiling voids and drains, so we can see the problem before anything is cut open.
- Risers and service ducts
- Toilet and washroom boxing
- Drains and wastes
How a commercial visit works
Plan the visit
We talk through the symptoms, the building and your opening hours, and agree a time and a price before anyone comes out.
Isolate and test
Zones are isolated and tested one at a time to find which part of the building is leaking, keeping the rest of the site running.
Pinpoint
Thermal imaging, acoustic tracing, tracer gas or a camera to find the exact spot, confirmed before any opening is made.
Repair and report
A small, targeted opening, the leak repaired and retested, and a written report with photos for your records and your insurer.
Commercial leaks we track down
- Heating systems losing pressure
- Underground mains supply leaks
- Leaks under solid concrete floors
- Leaks in risers, ducts and ceiling voids
- Water coming through between floors and units
- Washroom, kitchen and shower leaks
- Unexplained rises in the water bill
- Trace and access for insurance claims
Plant rooms, risers and service areas
Boiler rooms, pump sets and service corridors: the commercial spaces where hidden leaks do the most damage.

Common questions
How much does commercial leak detection cost?
It depends on the size of the building and how hard the leak is to find, so we agree the price with you before we start. If we find the leak we can usually repair it on the same visit.
Will we have to close while you work?
Usually not. We isolate and test one part of the system at a time and can come early, late or at weekends so the work fits around your trading hours.
Do you provide reports for insurers and landlords?
Yes. You get written findings with photos showing where the leak was, the likely cause and the repair carried out, which you can pass straight to your insurer, landlord or facilities team.
Do you work with managing agents and landlords with several properties?
Yes. We work with landlords, letting agents and managing agents across London and are happy to set up account work, purchase orders and a single point of contact.
Can you come out in an emergency?
Yes. We cover every London borough 24 hours a day. If water is coming through, turn off the stopcock for the affected area if you can do so safely, and call us straight away.
Do you repair the leak as well?
Yes. Once the leak is found we fix it, retest the system and leave it working, so you are not waiting for a second contractor.
