Leak detection in Hemel Hempstead

In Hemel Hempstead, leaks often hide in solid floors: underfloor heating in a home extension, or a pipe under a business unit. We test until one pipe proves to be leaking, then trace it from above and mark the spot.

Hemel Hempstead was among the first new towns after the war, built around an older market town that already had Victorian houses. Much of the town dates from those new town years, and some homes have since been extended, sometimes with underfloor heating set into the new floor.

A large business area sits on the town's eastern side, so water leak detection in Hemel Hempstead covers units and yards as well as homes. Business pipes often run under concrete from a meter near the site entrance, and most owners would rather keep trading.

Common Hemel Hempstead jobs

A business water bill with no water in sight

The property

A workshop unit on one of the business estates, with a kitchen and two toilets at the back fed by a plastic pipe under the concrete floor.

The problem

The water bill had jumped, yet staff had seen no water anywhere. With the unit shut and nothing running, the meter near the site entrance kept turning.

How we found it

Closed off in turn, the toilet branch failed a pressure test while the kitchen held. Tracer gas fed into it rose through a crack in the floor by the partition wall.

The outcome

We marked and photographed the crack. Payment had been taken before the visit, the business passed the report to its landlord's insurer, and the floor repair was quoted separately.

Underfloor loop leaking in a rear extension

The property

A new town semi with a single-storey kitchen extension, heated by underfloor pipes from a small manifold in the utility room.

The problem

The boiler pressure kept sinking within days of a top-up. Floors looked dry, and a heating engineer had checked the boiler and found nothing wrong.

How we found it

Shutting the three loops one at a time showed the one under the dining end losing pressure. With the floor warmed up, thermal imaging picked out a spreading patch; tracer gas confirmed it.

The outcome

We marked the tile and photographed it, so only a small area of floor needed lifting. The repair was quoted separately.

Who we help around Hemel Hempstead

Owners of extensions with underfloor heating

Pressure that drops with no damp anywhere is the usual sign. We close the loops at the manifold one at a time, then trace the leaking one across the floor.

Businesses on the town's estates

A unit's bill can jump long before any water shows. For business bookings we may take payment before confirming, and cancellations need at least a working day's warning.

Households with a leak outside

If the meter keeps turning with the stop tap closed, water is escaping between the two, under a lawn, path or drive. That stretch is where we listen.

Affinity Water on homes and business sites

Affinity Water supplies Hemel Hempstead. The company's part of the pipework stops at the meter or boundary; the rest usually falls to the owner. On business estates the meter may sit by the site entrance, and one meter can feed more than one unit, so find out what yours supplies before we visit.

Narrowing a Hemel Hempstead leak down

1

Supply, heating or hot water

Our engineer Charlie tests each system on its own. The meter shows whether mains water is escaping, the boiler gauge whether the heating is, and the hot side can be shut off separately.

2

Down to one run of pipe

Closing valves, branches or underfloor loops one by one shrinks the search to a single length: the yard pipe, a toilet branch, or one loop in an extension floor.

3

Pinpoint, confirm and mark

We pick the method that suits that length and find the leak, and a different test must agree. Only then do we mark it and take photographs for your report.

Methods for Hemel Hempstead homes and units

Thermal imaging for underfloor heating

Underfloor heating leak detection in Hemel Hempstead needs a warm floor. Each loop then shows on the camera, and a leak appears as warmth widening away from the pipe.

Acoustic listening outside

Under lawns, paths or yards, a ground microphone tracks the sound of water forced from the pipe. For external leak detection in Hemel Hempstead it is our usual first tool.

Tracer gas

Plastic pipe under thick concrete can be almost silent. So we fill the isolated pipe with a hydrogen and nitrogen mix, and a detector finds where it surfaces above the leak.

Business policies and the landlord's insurer

If you rent a unit, your landlord may insure the building rather than you, so check whose policy covers pipework before booking. For trace and access in Hemel Hempstead homes, read the policy and find out whether your insurer expects to approve the visit beforehand. Our report gives the location, methods, readings and photographs.

Common questions in Hemel Hempstead

We can, for shops, offices and industrial units, using the same tests as in homes. For businesses, payment may be taken before the date is confirmed, and no find, no fee on home water leaks does not apply to business premises.

At the manifold, usually in a cupboard or utility room, every loop can be shut off separately. We isolate them in turn until one fails to keep its pressure, then follow that loop across the warm floor using thermal imaging.

Only over the marked spot, once the leak is confirmed and the repair agreed; never to search. Pipe laid in ducting, wrapped in insulation or under a membrane limits what any survey can see, and we will tell you if that applies.

Clear access to the rooms the pipes cross, to the meter and stop tap, to every valve, and to the manifold if the floor is heated. Stop taps and valves must turn for testing to work, and free parking has to be within 100 m.

Visits are usually booked within 24 to 48 hours, and lines are open 8am to 8pm, every day. If it is a unit, let us know when the site is open and who has keys to the meter cupboard or yard.
