Leak detection in Chalfont St Giles

In a big house with radiators on several floors, falling boiler pressure could mean a leak almost anywhere. Our engineer Charlie tests each part alone, then finds the leak before floors come up.

Chalfont St Giles grew up around its green, where the oldest cottages still stand. On the lanes out of the village, houses are larger, often detached, with radiators on two or three floors. Leak detection in Chalfont St Giles often means searching a big system for one weak joint.

A sealed heating system is meant to keep the same pressure week after week. If yours keeps dropping, water is escaping from the pipes somewhere, often without a mark. The job is to find which section is losing it, then the exact point on that section.

Pressure loss in a large detached house

The property

A detached house on a lane outside the village, with radiators on three floors and the heating split into two zones, upstairs and downstairs.

The problem

The boiler needed topping up every three or four days. A heating engineer had checked it and found nothing wrong, and no damp showed anywhere.

How we found it

No sealer had been added. Testing each zone alone showed only upstairs losing pressure. Thermal images then found a warm line across a spare room ceiling, and tracer gas confirmed it.

The outcome

The spot beside a ceiling joist was marked and photographed. The joint was repaired at a price agreed beforehand, and the report went to the owners' insurer.

Gas pipe under a cottage garden, once made safe

The property

A cottage set back from the road near the green. Its gas meter sits in a box by the front gate, with the pipe buried under the garden.

The problem

The owners smelled gas in the front garden and called the gas emergency service. Once the supply was safe, their gas engineer needed to know where to dig.

How we found it

With the pipework already isolated, it was filled with tracer gas, a hydrogen and nitrogen mix. A sensor moved along the pipe's line found the strongest reading beside the path.

The outcome

The point was marked and photographed for the gas engineer, so only a small patch of garden came up. The repair and reconnection were left to them.

Who we help around Chalfont St Giles

Owners of large homes on several floors

Several floors of radiators and more than one heating zone mean a lot of pipe to search. Testing each zone alone shows which floor to start on.

Homes where the gas has been made safe

If you can smell gas, ring the gas emergency service first. Once the supply is safe, we trace the leak so your gas engineer knows where to work.

Owners making an insurance claim

Some insurers want written evidence before agreeing to floors or walls being opened. Our report gives the location, methods, readings and photographs for that conversation.

What your water company can and cannot do

Your water supplier is whichever company your bill names. When its meter readings show water flowing nonstop, it may write to warn of a leak on your side. It looks after everything up to your boundary or meter, and the rest is normally yours. A leak on sealed heating will not move the meter.

How a heating leak is tracked down

Top-up history and sealer

On the phone we want to know your top-up routine, the floors the pipes cross, and whether sealer is in the system, since sealer can hide the leak.

Split the system

Valves are closed so each part of the heating is tested alone against a pressure gauge. Where the gauge falls, that part is the one leaking.

Find it while warm

With the heating running, a thermal camera picks up warmth from the leaking pipe through floors and ceilings. A second method confirms it before the spot is marked.

Tools for heating and gas pipes

Pressure testing

Closing off one section and watching the gauge shows which part of a large system loses water, and a single test can rule out half the house.

Thermal imaging

Escaping heating water warms the floor or ceiling around it. The camera shows that warmth as a coloured patch, so boards stay down while we follow it.

Tracer gas

A hydrogen and nitrogen mix goes into the isolated pipe, escapes at the leak and is picked up at the surface by a sensor. It suits gas and heating pipes.

Before you claim, call your insurer

Check your policy before booking anything. Some insurers ask to approve the work first, and it is easier to know that before the visit than after it. If yours is happy for you to arrange the search, our written report gives the location, methods, readings and photographs for the claim.

Common questions in Chalfont St Giles

What does the price cover on a big house?

You get a price in a call or an email before the booking is made. It covers a half-day or full-day booking, and stays the same even if the leak shows itself early. Tell us how many floors and heating zones you have, so we book enough time.

Our house has four bathrooms. Does that change anything?

It changes which terms apply. No find, no fee on home water leaks does not extend to a house with more than one kitchen, or four or more bathrooms and toilets, so the price we quote is charged however the search goes. The testing itself works the same way.

Should the heating be running when you get here?

Usually, yes. A warm system makes a leaking heating pipe stand out to the thermal camera through floors and ceilings. When you book, we will tell you whether to switch it on before we arrive, and for roughly how long.

I can smell gas. Should I call you?

Not first. If you can smell gas, ring the gas emergency service first. Once they have made the supply safe, tracer gas can show where the isolated pipework is leaking, and we mark the point. The repair and reconnection are for a registered gas engineer.

Do you cover the cottages around the green?

We do. Our leak detection in Buckinghamshire takes in the cottages by the green and the larger houses on the lanes. Older cottages often have pipes on routes added over the years, so testing first shows which one is losing water. Tell us about any alterations.
