Leak Detection in Lewisham and Dulwich
Lewisham, Ladywell and Hither Green are Victorian terrace territory, while Dulwich Village and East Dulwich add big period houses and side return extensions. All of them have hidden pipework that ages at the same rate.

Leaks in Lewisham and Dulwich homes
Ladywell, Hither Green and the streets around Lewisham centre are rows of Victorian terraces with suspended timber floors and bathrooms that were added later, often above the kitchen. East Dulwich is much the same but with more side return kitchen extensions and loft conversions. Dulwich Village and West Dulwich have larger Georgian and Victorian houses with long gardens and long supply pipes, plus some post-war estates. Lewisham town centre has new high rise flats with plastic pipework. In the terraces the weak points are old copper pipes joined to new plastic several times over and the waste and overflow on a bath that sits above the hallway.
We cover SE13, SE21 and SE22, including Ladywell, Hither Green, Lewisham centre, Dulwich Village, West Dulwich and East Dulwich. Most calls are a ceiling stain under a bathroom, a musty smell under a side return floor, or a boiler losing pressure. Dye tests on each bath, shower and basin show whether the fitting or the pipe is at fault. Thermal imaging shows heating pipe runs under boards, and tracer gas confirms the point where a pressurised circuit is leaking. Corroded copper under a kitchen floor is checked with a borescope through a small hole before anything is lifted.
Most roads here are permit parking during the day, so we bring the kit in on a trolley and ask for a visitor permit if needed. Dulwich Village roads are more open. We keep the survey tidy and only open up where a repair has been agreed. The written report includes photographs, thermal images and readings and is set out for a trace and access claim on your buildings insurance.
What we detect in Lewisham and Dulwich

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
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
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 Lewisham and Dulwich: questions answered
How quickly can you reach Lewisham or Dulwich?
Usually the next working day. We travel across from Watford, and we group south east London visits so a sooner slot is sometimes possible.
Do you cover East Dulwich and Hither Green?
Yes. All of SE13, SE21 and SE22, including Lewisham, Ladywell, Hither Green, Dulwich Village, West Dulwich and East Dulwich.
My Victorian terrace has a damp patch at the bottom of the stairs. Where would it come from?
In this type of house the usual causes are the bathroom above, a heating pipe under the hall boards, or the supply pipe where it enters under the front step. We test each in turn rather than guessing, starting with moisture readings and thermal imaging.
What does escape of water mean on my policy?
It is the part of a buildings policy that covers damage caused by water leaking from pipes, tanks or appliances. Trace and access is the separate part that pays for locating the leak and making good what was opened. Our report keeps the two apart so each can be claimed.
