Leak to dry to treated, one company in Colliers Wood

Colliers Wood's housing stock ranges from 1960s and 1970s high-rise blocks around the town centre to Victorian and Edwardian terraces converted into flats near Christchurch Road, plus newer riverside apartments along the Wandle. This mix of ageing tower block plumbing risers, subdivided terrace bathrooms and modern flood-plain developments creates varied conditions for hidden leaks to take hold unnoticed.

Areas of Colliers Wood we cover

Common leaks in Colliers Wood homes

High-rise flats with shared risers and flat roofs

The tower blocks around Colliers Wood town centre rely on communal risers and flat roofing that were never designed to last indefinitely. A failed roof membrane or a corroded pipe joint several floors up can send water tracking down through ceiling voids, showing up as a stain two or three flats below long before anyone traces the actual source.

Converted Victorian terraces with stacked bathrooms

Many terraced houses near Christchurch Road and Merton Park have been split into flats, often with a bathroom built directly above another on a floor plan never intended for it. Perished seals around baths and shower trays let water seep into old timber joists, so damp patches on a ground floor ceiling frequently mean a leak has been running unseen upstairs for some time.

Riverside developments near the Wandle

Newer apartment blocks built close to the River Wandle bring pressurised plumbing systems, en suite bathrooms and multiple wet rooms stacked over living spaces. Escape of water from a failed compression fitting or a cracked shower tray seal can travel through party floors into neighbouring units, causing damage that is often discovered only once it reaches a lower flat's plasterboard.

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.
