Leak Detection in Pinner
Pinner, Hatch End and Eastcote are Metroland at its best, with 1930s houses that have been extended, re-plumbed and lived in for ninety years.

Leaks in Pinner homes
The houses around Pinner village, Hatch End and Eastcote were built for the Metropolitan line in the 1920s and 30s with suspended floors at the front, solid floors at the back, and copper heating pipes added in the 1960s and 70s. Loft conversions and rear extensions have since put bathrooms over kitchens and living rooms.
We cover all of HA5. The most common call is a boiler losing pressure, which we chase with a pressure test, thermal imaging of the pipe runs and tracer gas to pinpoint the leak in the screed. Bathroom leaks over kitchens are traced fitting by fitting with dye and moisture readings so the report says exactly what is at fault.
Parking is unrestricted on most roads. You receive a written report with photographs and readings in the format insurers accept for trace and access claims, and a fixed price for any repair before it starts.
What we detect in Pinner

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
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
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 Pinner: questions answered
Do you cover Hatch End and Eastcote?
Yes. All of HA5 including Pinner Green, Hatch End and Eastcote.
Can you find a heating leak without lifting the floor?
Yes. Thermal imaging shows the pipe run through the floor finish and tracer gas confirms the leak point, so only a small area is opened for the repair.
How soon can you visit Pinner?
Usually the same or next working day.
What do I need to do before you arrive?
Nothing special. If you can, note when the pressure drops or the meter turns, and clear access to the boiler and stopcock.
Suspect a leak in Pinner?
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.
