Leak Detection in Chiswick
Chiswick is Victorian and Edwardian houses in Bedford Park, Grove Park and the Glebe, riverside cottages at Strand on the Green and modern flats along the river. Many have been extended, which is where leaks tend to appear.

Leaks in Chiswick homes
Bedford Park has large late Victorian houses, many with later side returns, loft conversions and basements. The terraces of the Glebe and the roads behind the main shopping parade are smaller Victorian and Edwardian houses, often divided into flats or extended into the garden with a new kitchen and bathroom. Grove Park adds Edwardian houses and interwar semis, Strand on the Green has older cottages near the river, and the riverside developments are modern flats with plastic pipework. Rear extensions with new bathrooms over old kitchens, and underfloor heating laid in extension screeds, are frequent sources of hidden leaks.
We cover the whole of W4. Typical calls are a bath or shower leaking into the kitchen below, a warm patch on an extension floor, a boiler losing pressure and a damp wall that returns after redecoration. Dye testing of baths, showers and wastes finds the fitting at fault. Thermal imaging follows heating and underfloor pipework through screed and floorboards. Tracer gas pinpoints the leak in pipework that will not hold pressure. For supply pipes under front gardens and side passages the acoustic ground microphone locates it from the surface.
Chiswick is permit controlled almost everywhere, so we plan for the zone and bring the equipment in on a trolley. Where a house is in a conservation area and the finishes matter, we locate the leak as precisely as the methods allow so the opening is small and in the right place. Plan for the survey to take between two and four hours. The written report with photographs, thermal images and readings is prepared for a trace and access claim on your buildings insurance.
What we detect in Chiswick

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
Underfloor heating leak detection
A leaking underfloor heating loop is found by isolating circuits at the manifold, then mapping the pipes with thermal imaging and tracer gas.
Underfloor heating
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
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 Chiswick: questions answered
How quickly can you reach Chiswick?
Usually the next working day from Watford, with same-day visits sometimes possible for an active leak.
Which parts of Chiswick do you cover?
All of W4: Bedford Park, Turnham Green, the Glebe, Grove Park, Strand on the Green, Gunnersbury, Chiswick Park and the riverside developments.
My new rear extension has underfloor heating and the floor is damp. Is that a leak?
It can be. We pressure test the underfloor loops at the manifold and use thermal imaging to follow the warm pipe. That shows whether the loop is leaking or whether the moisture is coming from elsewhere, such as the old external wall.
Does a dye test damage the bath or tiles?
No. The dye is rinsed away afterwards. It simply shows whether water from the bath, shower tray, waste or overflow is the water appearing below.
