Leak Detection in Hemel Hempstead
Hemel Hempstead spans the New Town neighbourhoods, the old town and Boxmoor, Apsley and Leverstock Green, with leak problems that differ street by street.

Leaks in Hemel Hempstead homes
The New Town neighbourhoods such as Adeyfield, Bennetts End, Highfield, Warners End and Grovehill were built in the 1950s and 60s with solid floors and heating pipes in the screed. Boxmoor and the old town have Victorian houses with suspended floors and long copper runs. Apsley and the canal have newer flats with plastic pipework and shared services.
We cover HP1, HP2 and HP3. In the New Town houses the usual job is a heating leak under the floor, traced with pressure testing and tracer gas and confirmed with the thermal camera. In older Boxmoor houses we look for leaks at pipe joints under bathrooms using dye tests and moisture readings. Supply pipe leaks under front gardens are found with the acoustic ground microphone on paving and tarmac.
Parking varies by neighbourhood but is rarely a problem. The report you receive includes photographs, readings and a clear statement of cause, written for a trace and access claim on your buildings insurance.
What we detect in Hemel Hempstead

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 mains and underground leak detection
Leaking supply pipes under driveways, gardens and concrete floors, located with acoustic and tracer gas kit so only one small excavation is needed.
Mains & underground
Acoustic leak detection
A ground microphone listens for the sound of water escaping under pressure through floors, concrete and paving, and the reading peaks directly over the leak.
Acoustic
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 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 Hemel Hempstead: questions answered
Do you cover all of Hemel Hempstead?
Yes. HP1, HP2 and HP3, including Boxmoor, Apsley, Leverstock Green, Adeyfield, Bennetts End, Grovehill and Warners End.
How do you find a leak under a concrete floor?
We pressure test to confirm it, put tracer gas into the pipework and follow it with the detector across the floor. The gas escapes at the leak and rises through the concrete to show us the spot.
How quickly can you get to Hemel?
It is a short run up the A41 from Watford. Same or next working day in most cases.
Can you find a leak in a flat with shared pipework?
Yes. We test each source in turn and use moisture mapping and thermal imaging to prove the route, which gives the managing agent what they need.
