Leak to dry to treated, one company in Hendon

Hendon's housing stock ranges from 1930s semi-detached and terraced homes around Church End and West Hendon to Edwardian conversions near The Burroughs and post-war purpose-built blocks such as Grahame Park. This mix of ageing pitched roofs, flat-roofed rear extensions, and multi-occupancy plumbing stacked above one another creates plenty of scope for hidden leaks to develop unnoticed.

Areas of Hendon we cover

We attend leaks right across Hendon and its neighbourhoods, including:

Common leaks in Hendon homes

Flat roof extensions on 1930s semis

Many Hendon semis added kitchen or bathroom extensions with flat felt or asphalt roofs, now decades old. As the covering perishes and blisters, water tracks along joists rather than showing at the obvious point of entry, leaving ceilings damp and ply decking rotten long before ceiling staining reveals a problem.

Converted flats with stacked bathrooms

Around Church End and The Burroughs, Victorian and Edwardian houses split into flats often have bathrooms directly above ground floor rooms. Failed shower trays, cracked grout or perished waste seals let water escape between floors, damaging the ceiling and joists below without any visible leak in the bathroom itself.

Ageing pipework in post-war blocks

Purpose-built flats such as those at Grahame Park rely on plumbing runs shared between neighbouring properties. Corroded joints, perished washers or a failed stopcock seal can send water through party walls or floor voids, affecting a flat below or beside the actual source long before the leak is traced.

Really impressed with the whole experience. The surveyor did a proper, thorough job and didn't rush anything, they got to the root cause of the damp and explained it all clearly. Detailed, professional and reassuring from start to finish. Couldn't recommend them more highly.

Highly recommend to anyone dealing with damp or mould issues.

Tip: If your water meter ticks over with every tap off, or a wall or ceiling stays damp with no obvious cause, there is a hidden leak. Finding it early is far cheaper than repairing the mould and damage it leaves behind.
