Leak Detection in Islington
Islington is Georgian and Victorian terraces, converted flats and basements, and in N1 we scanned a hallway floor with thermal imaging to trace a leak without lifting it.

Leaks in Islington homes
Islington, Canonbury, Highbury and Barnsbury have Georgian and Victorian terraces, most divided into flats with a basement or lower ground floor that takes every leak from above. Pipework has been added in every decade since the houses were built and runs through party walls, ceilings and under stone floors.
In Islington we used the thermal camera on a hallway floor to show the pipe runs and the wet patch through the finish, which put the leak in one place before any floor was touched. That is the usual approach across N1, N5 and N7: thermal imaging to map, tracer gas or acoustic listening to pinpoint, moisture readings to show the extent, all in a report the freeholder and insurers can use.
Parking is controlled everywhere, so we carry the equipment in and plan the visit around a bay or a visitor permit. The report covers cause, location and damage with photographs and readings for a trace and access claim.

What we detect in Islington

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
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 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 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 Islington: questions answered
Do you cover Highbury, Canonbury and Holloway?
Yes. N1, N5 and N7 including Canonbury, Highbury, Barnsbury, Holloway and De Beauvoir.
Can you survey a basement flat that keeps getting wet?
Yes. We test the flats above, trace the pipe routes with thermal imaging and map the moisture so the source is proved rather than guessed.
Do you work with freeholders and managing agents?
Yes, regularly. The report is written so responsibility between flats is clear.
How quickly can you get to Islington?
Usually the next working day.
