Leak Detection in Letchworth and Baldock
Letchworth has the first garden city houses with roughcast walls and timber floors, plus later estates to the south and east. Baldock adds a Georgian high street and the Clothall Common estate.

Leaks in Letchworth and Baldock homes
The early garden city houses around the town centre, Norton and Willian were built in the early 1900s in the Arts and Crafts style. They have roughcast render, suspended timber floors and plumbing that has been renewed many times since. The Jackmans and Grange estates and the Lordship area were built after the war with solid floors and heating pipes in screed. Baldock has Georgian and older houses along the high street with thick walls, Victorian terraces behind them and the 1980s and 90s houses of Clothall Common with plastic pipework. Ashwell, Weston and Wallington add cottages and barn conversions with underfloor heating.
We cover SG6 and SG7, including Norton, Willian, Jackmans, the Grange, Lordship, Baldock, Clothall Common, Ashwell, Weston and Wallington. The common calls are a ceiling stain under a bathroom in a garden city house and a boiler losing pressure in a post-war house. Low pressure at the taps often means a supply pipe is leaking. Thermal imaging suits the timber floors of the older houses because the warm pipes show through the boards. Tracer gas suits the screed floors and the thick walls in Baldock. The acoustic ground microphone finds supply pipe leaks under front gardens and paths.
Parking is easy on most garden city roads and on the estates, and tighter along the Baldock high street, where we carry the equipment in. Floors are protected and any opening up stays at the marked point. You receive a written report with photographs, thermal images and readings that explains the cause and the location in plain terms. It is written for a trace and access claim on your buildings insurance. The detection, the access and the repair are shown separately so the claims handler can see each part.
What we detect in Letchworth and Baldock

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
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
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 Letchworth and Baldock: questions answered
How soon can you get to Letchworth or Baldock?
Usually the next working day. Both towns are at the top of the A1(M) from Watford, so we plan visits there with Hitchin and Stevenage. If water is coming through a ceiling, say so when you call and we will give you an honest time.
Which parts of Letchworth and Baldock do you cover?
All of SG6 and SG7, including Norton, Willian, Jackmans, the Grange, Lordship, Baldock, Clothall Common, Ashwell, Weston and Wallington.
My garden city house has roughcast render. Does that make a difference to a leak?
It can hide one. A damp patch on rendered masonry often shows on the inside before the outside. Thermal imaging and a moisture meter show where the water is sitting and whether it is coming from a pipe, a bathroom fitting or the outside of the building.
What does trace and access cover actually pay for?
It pays for locating a hidden leak and for making good the floor, wall or ceiling opened to reach it. The pipe repair itself is usually not covered. Our report keeps the three parts separate so your insurer can see what each one is.
