Before you demolish in City of London
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.
