Leak to dry to treated, one company in Mill Hill

Mill Hill's housing stock ranges from 1930s semis and mock-Tudor detached houses around the Ridgeway to post-war estates, bungalows near Highwood Hill and newer flats around Mill Hill East and the Broadway. Many older properties have added flat-roofed extensions and en-suite bathrooms over the decades, while ageing plumbing and converted lofts create ready routes for hidden water to travel unseen between floors.

Areas of Mill Hill we cover

We attend leaks right across Mill Hill and its neighbourhoods, including:

Common leaks in Mill Hill homes

Flat roof leaks on extensions and garages

Mill Hill's 1930s semis and detached houses are frequently extended with flat-roofed kitchens, garages or dormer additions. Felt and older asphalt coverings degrade with age and sun exposure, letting water seep in gradually rather than through an obvious hole. It tracks along joists and down internal walls, often surfacing as damp patches or bulging plaster well away from the actual entry point on the roof.

Bathrooms leaking into rooms below

Many Mill Hill homes have had en-suites or upstairs bathrooms added since original construction, often above kitchens or living rooms. Perished silicone seals around baths, showers and tiling let water escape slowly with everyday use rather than an obvious burst. Over months this saturates the subfloor and ceiling below, showing up as staining, sagging plasterboard or a musty smell before residents realise there is an active leak.

Hidden pipework failures in older and converted properties

Properties around Mill Hill Village and the Broadway mix original 1930s pipework with later alterations for loft conversions and extensions, creating joints and concealed runs that are easy to overlook. Escape of water from a corroded or poorly connected pipe inside a wall or under floorboards can continue unnoticed for weeks, causing timber decay, mould growth and damage to neighbouring flats in converted or subdivided buildings.

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.
