Heating and supply leaks, Sandy

Leak detection in Sandy for heating and supply pipe leaks

Sandy's 1970s homes often have heating pipes set in solid floors, so a boiler that keeps losing pressure usually means a leak underneath. Our engineer Charlie traces it from the surface.

Two building booms shaped Sandy: overspill estates for families leaving London in the 1970s, then more housing in the 1990s. Leak detection in Sandy often comes back to that first wave, where many of the houses have heating pipes, some quite thin, set in concrete floors.

The 1990s homes tend to have plastic supply pipes, en suites and, in some, underfloor heating. Plastic pipe leaks quietly, which matters when we come to listen for it. If the house is let, say so when you book, and tell us who has the keys.

What a typical Sandy leak looks like

Heating leak hidden under kitchen units

The property

A 1970s terrace from the town's first big expansion, its thin heating pipes buried in the concrete floor, with a newer fitted kitchen.

The problem

Since a kitchen refit, the boiler had needed topping up every couple of days. Nothing looked wet, and a service found the boiler sound.

How we found it

No sealer had been added, and isolating the boiler showed the pipework was losing the pressure. Once warm, the heating showed as a hot strip on the camera along the plinth under the sink; tracer gas confirmed it.

The outcome

The plinth and one base unit came out, and the floor was opened over the mark. The repair was quoted separately, done while we were there and guaranteed for 3 months.

Empty house between lets, meter still turning

The property

A 1990s semi, let through an agent and empty between tenants, with blue plastic pipe under the front lawn from a pavement meter.

The problem

At the check-out visit the agent saw the meter moving with every tap off and nobody living there, yet the garden stayed dry.

How we found it

Closing the stop tap under the sink left the meter turning. Plastic pipe gave little sound, so we filled the line with tracer gas, which rose under the path, where a faint hiss agreed.

The outcome

We marked and photographed the spot for the landlord, and the path was opened in one place before the new tenants moved in. The repair was quoted separately.

Sandy homeowners and landlords we help

Owners topping up the boiler

Refilling the boiler every few days while nothing looks wet usually points to a hidden heating leak. Mention any sealer you have added, as it can stop the tests working.

Landlords between tenants

An empty house with the meter still turning needs checking before the next tenant arrives. We need keys, working stop taps and the meter reachable.

Households with a letter about the meter

When the water company reports constant use on your meter, we split inside from outside at the stop tap, then follow the outside pipe to the house.

Testing your own meter in Sandy

Bedfordshire is split between water companies, so check which one is named on your bill. Water leak detection in Sandy can start with you: turn everything off, note the meter and look again after an hour. If it has crept on, shut the inside stop tap and try again. Still moving means a leak outside, on the pipe from the meter, which is usually the owner's.

How we trace a Sandy heating leak

1

Top-ups, floors and sealer

Three questions come first: how often the boiler needs refilling, whether the pipes are in solid floors or under boards, and if sealer is in the system.

2

Pressure and isolation

With the system at pressure, the boiler and then each part of the pipework are shut off in turn. Whichever part keeps losing pressure on the gauge holds the leak.

3

Heat first, then proof

Once the heating is warm, the camera shows where warmth escapes into the floor. Only when a second test lands in the same place is the spot marked and photographed.

Methods that suit Sandy homes

Thermal imaging

Warm water leaking into a concrete floor leaves a patch the camera can see, clearest after the heating has run and weaker under thick rugs or wood.

Pressure testing

A gauge on a sealed section shows whether it holds. On heating it narrows the search to one circuit, and afterwards it proves the repair.

Acoustic listening

For external leak detection on a supply pipe, a ground microphone moves over lawn or paving to catch the hiss of pressurised water; quiet plastic pipe is harder.

Heating leaks and your home policy

If you have trace and access cover, check it applies to heating leaks as well as the water supply, and ask if the insurer wants to agree the work. We agree the detection price before you book and quote any repair separately. The report follows payment and gives the location, methods, readings and photographs.

Common questions in Sandy

Yes, so mention it when you book. Sealant in a heating system can stop testing working, which means a leak may not show on the day. Knowing beforehand lets us plan the visit, so tell us roughly when it went in.

No. Central heating sits outside no find, no fee on home water leaks. A heating visit costs the price you agreed before booking. That price buys our time on site, booked in half-day or full-day blocks, and a quick find leaves it unchanged.

Not to find it: that is done from the surface. Once the spot is confirmed, a small area over it is opened for the repair, which we can usually do ourselves, quoted separately, leaving the rest of the floor whole.

It is. Each loop is closed at the manifold in turn to find the one losing pressure, then followed with thermal imaging once the floor is warm. A membrane or insulation wrapped round the pipes may limit what can be seen.

Visits are usually booked within 24 to 48 hours. Lines are open 8am to 8pm, every day: ring 07700 102 008 and say how often the boiler needs refilling, or whether the meter moves with every tap in the house closed.
