Before you demolish in Greenwich

Why Leak Detection Before Demolition

Preserve your London property

London property values mean unnecessary demolition is extremely costly. Our non-invasive methods locate leaks to within 30cm accuracy — often without lifting a single floorboard or removing a single tile.

Insurance-approved methods

Our leak detection reports and methodology are accepted by all major UK home insurers. We liaise directly with loss adjusters and provide the documentation needed to support escape-of-water claims under your buildings insurance policy.

Subsidence and damp

Long-term hidden leaks cause foundation movement in London's clay soil. If you have unexplained cracks appearing in walls, rising damp with no obvious source, or a persistently high water bill — a leak detection survey can rule out or confirm a hidden leak.

Water bill check: if your Thames Water bill has increased unexplainably, or your meter continues ticking with all taps off, you likely have a hidden leak. The average hidden pipe leak wastes 400–500 litres per day — costing £300–£500 per year in wasted water.

Leak Detection Greenwich: frequently asked

How much does leak detection cost in Greenwich?

Leak detection in Greenwich from Prestige Engineers starts from £200 for an acoustic or thermal imaging survey of a standard property. More complex properties or multi-method surveys are priced from £300–£450. Trace and access (exposing the leak after location) is charged separately. We cover Greenwich, Woolwich, Eltham, Charlton.

Can you detect leaks without breaking floors or walls in Greenwich?

Yes — our acoustic listening equipment, thermal imaging cameras and tracer gas methods locate leaks non-invasively to within 30cm of the leak source. In the majority of cases across Greenwich properties we locate the leak without breaking any floors, walls or tiles.

Will my insurance cover leak detection in Greenwich?

Most home insurance policies include trace and access cover — the process of locating and exposing a hidden leak. Check your policy wording for "trace and access" or "escape of water". We provide our reports in the format required by insurers and can liaise directly with loss adjusters in Greenwich.

How do I know if I have a hidden leak in Greenwich?

Common signs of a hidden leak in Greenwich properties: unexplained damp patches on walls, ceilings or floors; a rising water bill with no change in usage; your water meter ticking with all taps turned off; soft or springy spots in flooring; mould or mildew growth with no obvious moisture source.
