Residential leak detection in West Midlands

For a West Midlands home, damp flooring and unusual water use may have more than one cause. ADI investigates concealed leaks across Birmingham, Coventry, Solihull and the Black Country. The Coventry investigation below identified both a faulty toilet valve and a damaged pipe beneath the hallway, with different follow-up work for each.

Coventry: two faults behind unexplained water loss

In an ADI residential investigation in Coventry, water pooled beneath the stairs and damp affected the hallway and bathroom. Separate tests identified a faulty toilet cistern valve and a damaged hot-water pipe beneath the hallway floor.

Tracer gas helped locate the concealed pipe fault. The damaged section was replaced and held pressure during the recorded retest. The toilet valve still needed replacement: it remained a separate recommendation.

The two findings required separate decisions: the concealed pipe was repaired and retested, while the toilet valve still required replacement. Continuing symptoms should be checked against the work actually completed.

Water leak detection for your home

The right investigation starts with the symptoms. These are the residential problems ADI can help trace.

Non-invasive methods for hidden water leaks

Your engineer selects tests to suit the suspected leak and available access. Not every survey needs every piece of equipment.

Read the surface evidence
Moisture and temperature patterns help guide checks. Thermal imaging does not see through walls, and a damp reading alone does not identify the source.
Test suitable pipework
Pressure testing, acoustics and tracer gas can help narrow the affected section. The system and available isolation determine which tests can be used.
Confirm what can be reached
Cameras and controlled water tests can investigate accessible voids, bathrooms or ingress. The report records findings and limits; further access may still be required.

Help for homeowners, landlords and residents

Houses and bungalows

A survey can follow a suspected leak from the incoming supply through to concealed hot, cold and heating pipes. Where the supply runs a long way under a garden, drive or forecourt, give the stop tap and meter positions and an approximate pipe route before the visit.

What to do when you spot a leak

Flats and maisonettes

One leak can affect several homes in a block, and the stain is often some way from its source. Say which flats are involved, whether the pipework is shared, and who holds access to risers, tank rooms and the flat above, so permission can be arranged before the engineer arrives.

Rented and managed homes

A landlord, a tenant or a managing agent can arrange the survey. Settle beforehand who authorises the work and who will let the engineer in, particularly where one address covers several occupied flats. The written findings and photographs can then go to whoever organises the repair.

Questions about leak detection in West Midlands

Does this cover the county or the wider West Midlands region?

The West Midlands county comprises Birmingham, Coventry, Dudley, Sandwell, Solihull, Walsall and Wolverhampton. It is distinct from the wider West Midlands region. Provide the property postcode to confirm survey arrangements and availability.

Can there be two separate causes of water loss?

Yes. The Coventry investigation found a faulty toilet valve and a concealed pipe fault. Repairing one did not remove the need to address the other, so the report separated completed work from recommendations.

Do I need to lift flooring before the engineer arrives?

No. Provide photographs and details of the symptoms and floor construction. The engineer selects suitable tests, and any additional opening up should be discussed and agreed separately.

What information is needed for a survey quote?

Provide the full postcode, property type, symptoms, previous investigations and access restrictions. Confirm the nominated site contact and who can authorise work. The office will discuss the scope, quote and current availability.
