Leak to dry to treated, one company in Arnos Grove

Arnos Grove is dominated by 1930s semi-detached and terraced houses built around the Piccadilly line's arrival, many with later single-storey rear and side extensions under flat roofs. Original bathrooms sit above kitchens with plumbing runs largely unchanged since construction, while post-war conversions into flats have added extra kitchens and bathrooms stacked awkwardly through older floor structures, raising the odds of a hidden leak going unnoticed.

Common leaks in Arnos Grove homes

Original 1930s bathroom plumbing wearing out unseen

Many Arnos Grove semis still run bathroom waste and supply pipework installed when the houses were built, tucked beneath floorboards and behind boxed-in panels. Joints and washers perish gradually rather than failing outright, so water can seep into joists and ceiling voids for months. Homeowners often only discover the problem once a ceiling below stains or sags, by which point the timber and plaster have already absorbed significant moisture.

Flat-roofed extensions prone to slow leaks

Rear kitchen extensions and converted garages are common across Arnos Grove's interwar streets, many finished with flat felt or asphalt roofing that has a shorter working life than the original pitched tiles. Once the membrane splits or pools with standing water, moisture tracks along roof timbers and down into the wall cavity below rather than dripping straight through, so damage to plasterboard and insulation can be well underway before any staining appears indoors.

Bathrooms leaking into flats below in converted houses

A number of the larger period houses around Arnos Grove and Bowes Park have been split into flats, with bathrooms stacked directly above neighbouring kitchens or living rooms. Grout and sealant around baths and shower trays degrade with normal use, and escaping water can run along old joists before showing as a stain on the ceiling of the flat beneath, making the true source of the leak harder to trace without opening up the floor.

★★★★★

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.

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.
