Leak Detection in West Hampstead
West Hampstead and Hampstead are mansion blocks and Victorian conversions where a bathroom leak in one flat becomes a ceiling stain in another, as an NW6 dye test showed.

Leaks in West Hampstead homes
West Hampstead, South Hampstead and Hampstead proper are full of large Victorian houses converted into flats, mansion blocks with shared risers, and a few streets of newer apartments near the stations. Bathrooms sit over other people's living rooms and the pipework runs through ceilings that nobody owns outright.
In West Hampstead we traced a bathroom leak with a dye test: the bath was filled with red dye and each route, the waste, the overflow and the seals, was tested in turn while the ceiling below was checked with moisture readings. The result named the exact fitting at fault, which is what the neighbour and both insurers needed. Where pipework rather than fittings is suspected, thermal imaging and tracer gas do the rest.
Parking is controlled everywhere, so we plan for a visitor permit or bay and carry the equipment in. The report covers cause and route with photographs, readings and the extent of damage for a trace and access claim.

What we detect in West Hampstead

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
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 reports
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
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
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 leaksFrom 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 West Hampstead: questions answered
Do you cover Hampstead, Belsize Park and Kilburn as well?
Yes. NW6 and NW3 including West Hampstead, South Hampstead, Hampstead, Belsize Park, Swiss Cottage and Kilburn.
What is a dye test?
We add coloured dye to the bath, shower or basin and test each route the water can take. The colour shows up below at the point of escape, so the fitting at fault is identified without guesswork.
The leak is coming from the flat above. Can you still help?
Yes. With access to the flat above we test it fitting by fitting. If access is refused, we document what we can see below and advise the managing agent.
How quickly can you come to West Hampstead?
Usually the next working day.
