Leak detection in Harleston for older town houses

Behind a Harleston front door, the supply may be very old and shared with next door. Our engineer Charlie finds which length leaks, then pins the point from the surface.

Georgian houses and older buildings line the main streets of Harleston, a small South Norfolk market town near the Waveney and the Suffolk border. Many are joined to their neighbours. Plumbing in houses like these has usually been altered several times, and that shapes leak detection in Harleston.

That history matters once water goes missing. The supply may be old metal rather than plastic, it may feed two houses, and nobody may know its exact route. So our first job is deciding which stretch of pipe is losing water, before anyone hunts for the point.

Typical leaks in Harleston's older houses

A forgotten pipe to an old outhouse

The property

A Georgian house on a main street. Its supply comes from a pavement meter, and an old branch off it once fed an outhouse tap in the yard.

The problem

Anglian Water wrote about constant use. The owner had already replaced a dripping stop tap indoors, but the meter still crept round overnight.

How we found it

Once the indoor stop tap was shut, the meter still crept. The main supply was quiet under the ground microphone, but a hiss came from the yard, on the forgotten branch; tracer gas confirmed it.

The outcome

We marked and photographed the spot. Cutting off and capping the unused branch was quoted separately and finished on the visit, and the meter then stood still.

Stain under a cottage bathroom, with every pipe sound

The property

An older cottage near Harleston with its bathroom fitted into a back bedroom, above the sitting room's old plaster ceiling.

The problem

A brown stain kept returning on the sitting room ceiling after showers over the bath. A plumber had checked under the bath panel and found nothing.

How we found it

Moisture readings mapped the stain. Both supply pipes held a pressure test and the waste stayed dry, but water splashed along a gap in the bath seal lifted the readings; thermal imaging agreed.

The outcome

No pipe was at fault. We marked and photographed the gap, and the owner had the seal redone by their own builder, with no floor opened.

Harleston owners we often hear from

Town houses on an old shared pipe

Some joined houses still draw water through one pipe that divides indoors. When Anglian Water writes to one household, we test each branch to put the leak on the right side.

Cottages with oil-fired heating

Whatever the fuel, a boiler gauge that keeps falling usually means water is escaping somewhere. Count the days between refills and check for any sealant poured in; both change how we test.

Cottage owners with a stain under the bathroom

Bathrooms in older cottages were often squeezed in later, over timber floors and fragile ceilings. Tray, waste and pipes are each tried separately before a single tile is lifted.

Shared supplies in Harleston

Anglian Water supplies Harleston. Its part usually ends at the boundary or the meter, and onward from there the pipe is normally the owner's. Where joined older houses take one supply, the leak may be on a stretch serving both homes. If you suspect yours is shared, say so early.

Working through an older house's pipes

1

Split the pipework

Supply, heating and hot water are isolated one after another. Whichever loses water or pressure becomes the focus, which spares searching every room of an old house.

2

Find the leaking stretch

On a shared or much altered supply, closing valves and stop taps in sequence reveals the failing section. Seized valves slow this down, so check yours turn.

3

Pin down the point

We trace that section from above ground, then a second method checks the result. Marking and photographing the point means any opening starts in the right place.

The tests that suit older houses

Pressure testing

A section is closed off and its gauge watched; if the needle sinks, that part leaks. Old metal and new plastic both suit it, provided the valves shut properly.

Acoustic listening

Metal pipe carries leak noise further than plastic does. We follow it with a ground microphone under steps, paths and lawns, and start looking where it is loudest.

Thermal imaging

Run the heating or hot water and a camera picks out warm pipe routes in floors and walls. Thick old masonry limits what it sees, so another test always backs it up.

Places we reach from Harleston

Bungay, Beccles, Halesworth and Eye, across the river in Suffolk, are old market towns as well. Diss, Poringland and the farms and hamlets of the valley are part of our leak detection in Norfolk.

Opening up an old floor for a claim

Taking up old boards or a stone floor is where a claim gets expensive, so it pays to open in one place. Our report marks that place, with the location, methods, readings and photographs. Exposure is the only true proof of a leak, and whether the claim succeeds is up to your insurer.

Common questions in Harleston

Yes, the search happens from the surface. Sound, heat and gas tests follow the pipe while boards and tiles stay where they are. Only the marked point needs opening for the repair, and we show you exactly where that will be.

Shared supplies sit outside no find, no fee on home water leaks, so the agreed price stands whatever we find; full conditions are on our terms page. Mention the shared pipe and your neighbour’s stop tap when booking, as we may need to get into both houses.

Usually, yes. Thermal imaging only works once the pipes are warm, so leave the heating on unless we say otherwise on the phone. Mention any sealant in the system when you book; some of our tests will not work with it present.

It can happen. Pressure on a weak pipe, whether from testing or a repair, can expose fresh leaks elsewhere along it; those would be priced as extra work. Repairs are guaranteed for 3 months, but only for the parts we put in, not the older pipes around them.

We need parking without charge within 100 m of the property, so warn us if the street outside is restricted. Any parking charges or tolls are passed on at cost. Once that is settled, visits are usually booked within 24 to 48 hours.
