Leak Detection in Putney
Putney has Victorian terraces off the High Street, Edwardian houses in West Putney and mansion blocks and estates in Roehampton, each with its own way of hiding a leak.

Leaks in Putney homes
The streets either side of Putney High Street are mostly Victorian terraces with suspended timber ground floors, cellars at the front and bathrooms added above kitchens. West Putney has larger Edwardian houses on wider plots. Roehampton is different again. It has post-war estates on communal heating and shared risers, the 1920s Dover House estate of cottage style houses, and private blocks of flats by the Heath. Along the river there are modern apartment buildings. Mansion blocks and estates bring shared pipework, so a leak often shows in one flat and starts in another.
We cover the whole of SW15, including West Putney, Putney Heath, Roehampton and Putney Vale. The usual calls are a ceiling stain under a neighbour's bathroom, a central heating system that needs topping up each week, and a damp patch low on a cellar wall. In the terraces we lift nothing to begin with. Thermal imaging and moisture readings show the wet area and a dye test on the bath and shower above narrows it down. In mansion blocks we test the flat above by source and trace the route with moisture mapping. Heating leaks are confirmed with a pressure test and found with tracer gas.
Parking in central Putney is controlled on most streets, so we bring the equipment in on a trolley and use a visitor permit where one is available. Roehampton estates usually have visitor spaces. We protect carpets and work room by room. Afterwards you get a written report with photographs, thermal images and readings, prepared for a trace and access claim. That can be on your own buildings policy or the block's.
What we detect in Putney

Water leak detection
Hidden leaks behind walls, under floors and in ceilings, pinpointed with thermal, acoustic and tracer gas kit before anything is opened up.
Water leaks
Central heating leak detection
A boiler that keeps dropping pressure means water is escaping somewhere in the heating circuit. We find the pipe or fitting and fix it.
Heating leaks
Tracer gas leak detection
A safe hydrogen and nitrogen mix is put into the drained pipe, rises through the floor or wall and is picked up by the detector directly above the leak.
Tracer gas
Thermal imaging leak surveys
A thermal imaging camera shows warm pipe runs and cool wet patches through floors and walls, so the leak is seen before anything is opened.
Thermal imaging
Trace and access insurance reports
Leak detection carried out and documented the way insurers expect, with a report your claims handler can act on straight away.
Insurance reportsFrom your first call to a leak you can see in the report
Call or WhatsApp with a few photos and a line about the symptoms. We ask a handful of questions, agree a fixed price and book the survey, usually for the same or the next day.
On arrival we pressure test the mains, hot water and heating, check the meter and test the escaping water, so we know what we are looking for before the detection starts.
Thermal imaging, the acoustic ground microphone and tracer gas are used as the pipework dictates until the leak is marked on the floor or wall.
You get a written report with readings, thermal images and photographs, ready for a trace and access claim. If you want the leak fixed, we open that one spot and repair it.
Leaks in Putney: questions answered
How soon can you get to Putney?
Usually the next working day. Putney is a run down from Watford through west London, and we can sometimes fit an urgent visit in sooner if water is coming through a ceiling.
Which parts of Putney do you cover?
All of SW15: central Putney, West Putney, Putney Heath, Roehampton, Putney Vale and the riverside.
I live in a Roehampton block with communal heating. Can you still find the leak?
Yes. We work with the managing agent to isolate what we can. Thermal imaging, moisture mapping and acoustic listening on the risers and the pipework in your flat then show where the water is coming from.
Is it safe to use tracer gas in a flat?
Yes. It is a mix of hydrogen and nitrogen put into a drained pipe at low pressure, and the detector reads it as it escapes at the leak. It is a detection method only and has nothing to do with gas appliances or the gas supply.
Suspect a leak in Putney?
Call now and we will tell you straight away whether it needs a same-day visit. Or send a photo of the stain, the meter or the boiler gauge on WhatsApp.
