Leak Detection in Rickmansworth
Rickmansworth, Loudwater, Moor Park and Mill End have big plots, long supply pipes and older heating systems, which is exactly where hidden leaks hide.

Leaks in Rickmansworth homes
Rickmansworth homes range from riverside cottages near the Aquadrome to substantial detached houses in Loudwater and Moor Park with long driveways and private supply pipes. The distance between the water meter at the boundary and the stopcock in the house is often thirty metres or more, and every metre is a place a mains leak can hide.
We cover all of WD3. Underground supply pipe leaks are the common call here, found by listening with acoustic equipment along the pipe route and confirming with tracer gas at inspection chambers, so the excavation is a small hole rather than a trench across the lawn. Inside, the older houses have gravity heating systems and copper pipes in screed that we trace with thermal imaging.
Access is easy on private drives, and we protect gravel and paving while we work. Every survey includes a written report with photographs, which Affinity Water and your insurer will accept for supply pipe and trace and access claims.
What we detect in Rickmansworth

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
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 Rickmansworth: questions answered
Can you find a leak on my supply pipe without digging up the drive?
Yes. Acoustic listening and tracer gas locate the leak from the surface, so the repair is a small excavation at the exact point rather than a trench.
Do you cover Loudwater, Moor Park and Chorleywood?
Yes, all of WD3 including Loudwater, Moor Park, Mill End, Croxley Green, Chorleywood and Sarratt.
My water bill has doubled. Is that a leak?
Often. Check the meter with everything off; if it is still turning there is a leak on your side of the meter. We can confirm it and find it in one visit.
How long does a survey in Rickmansworth take?
Most take two to four hours depending on the size of the property and how many pipe runs need checking. We tell you the answer before we leave.
