Plumb Heating Ltd is a Gas Safe registered plumbing and heating company serving Welwyn Garden City and the surrounding AL7 and AL8 postcodes. The engineers who carry out our plumbing and heating work in Welwyn Garden City also handle leak detection – with honest advice and a price agreed before any work begins.
Welwyn Garden City was built in phases, and each era has its own weak points – from original 1920s pipework in Handside to small-bore pipes set in concrete floors in Panshanger. We know where to look, and we find leaks without breaking out more than we need to.

These are the symptoms we hear about most from WGC homeowners:
Many 1960s and 1970s homes have heating pipes buried in the floor slab. A warm area underfoot is often the first sign of a pinhole leak below.
Pressure dropping with no drip from radiators or valves usually means water is escaping from pipework you cannot see.
In town centre flats a leak quickly affects neighbours. Fast, accurate location limits the damage on both sides.
Older homes in Handside and Sherrards Wood have pipework that has been altered many times – a common source of slow, concealed leaks.
Hissing or trickling in walls or under floors when nothing is on means water escaping under pressure.
If your usage has not changed but your bill has, check the meter with everything off – a moving dial confirms a leak.
We use the method best suited to the house and its pipework:
The quickest way to find leaks in pipes buried in concrete – common across Panshanger and the postwar estates. The camera shows the pipe route and the hot spot where water is escaping.
Picks up the sound of escaping water through floors and paving, helping us confirm the exact point before any concrete is broken out.
A harmless gas escapes at the leak and is detected at the surface. Ideal for supply pipes under paths and front gardens.
Here is what to expect from a visit:
We check the symptoms, the boiler pressure history and the age of the property.
These confirm whether the heating or supply is losing water, and how quickly.
Thermal imaging maps the pipework; acoustic detection or tracer gas confirm the exact leak point.
We show you the leak and explain the repair before any work begins.
Repairs are usually completed the same day, with an insurance report if required.
Across Welwyn Garden City's different housing eras:
Pinhole leaks in buried small-bore pipework, typical of 1960s and 1970s homes.
Bathroom and kitchen leaks in town centre apartments, located quickly to limit damage.
Joints and pipes in the original garden city homes, altered over many decades.
Leaks under front gardens and paths, often noticed as low pressure or a higher bill.
Failed seals and trays leaking into ceilings below.
Tired valves and fittings around hot water cylinders.
When pipes are buried in concrete, guessing the location can mean breaking out large areas. Pinpointing it first keeps the job small.
We carry out leak detection across all of Welwyn Garden City and the surrounding Hertfordshire area. These are the locations we cover most regularly:
The original garden city homes west of the railway line, some of the oldest housing in WGC. Older pipework and decades of alterations make concealed leaks behind walls and under floors a common callout. AL8.
Town centre properties and flats, where a leak can affect neighbours below as well as your own home. Fast, accurate location is especially important here. AL8.
1970s housing with pipework often set in solid floors. Pinhole leaks in buried heating pipes are one of the most frequent problems we find in this area – thermal imaging is the quickest way to locate them. AL7.
Postwar estates with homes from the 1950s to the 1980s. Supply pipe leaks and leaks in heating pipework under solid floors are the typical callouts. AL7.
Residential streets with a mix of property types and ages. Bathroom, kitchen and central heating leaks make up most of our work here. AL7.
The historic village of Welwyn and the Digswell area, with period properties and some long external water mains. AL6.
