Damp, Mould & Leak Advice

The common causes of plumbing leaks and the non-destructive methods used to trace them accurately before damage spreads.

Neither green nor black mould is automatically worse: colour cannot identify the species or risk, so the moisture source and exposure matter most.

Tenants have strong legal rights when a landlord ignores damp and mould, and a documented survey is often the fastest way to compel repairs.

Black mould on a bedroom ceiling is nearly always condensation. Learn the causes, how to treat it safely, and how to stop it returning.

Found a water leak in London? Shut off your stopcock, call a plumber, then arrange leak detection and drying to stop lasting damp and mould.

Damp and mould are common in Southwark's Georgian and Victorian housing because of solid walls and non-breathable repairs that trap moisture.

If you rent and find black mould, report it to your landlord in writing with photos immediately, keep records, and understand your legal protections.

Learn how to spot bathtub leaks early, trace the source, repair it correctly, and dry the structure before damage spreads.

Black mould on carpet is caused by trapped moisture in the fibres and underlay, poses real health risks, and rarely clears without fixing the source.

Structural drying removes trapped moisture from a building's fabric after leaks, floods or damp, using monitored equipment to protect the property from lasting damage.

Black mould spores are microscopic cells that spread through the air and regrow wherever moisture is present, so fixing the damp source is essential.

A shower leak spreads fast through joists and plaster, so learn the signs, find the true source, and fix it before it becomes structural damp.
