Damp, mould & leak services in Merton

Merton's housing spans Victorian and Edwardian terraces around Colliers Wood and South Wimbledon, 1930s semis in Morden and Raynes Park, mansion blocks near Wimbledon Park, and post-war estates towards Mitcham and St Helier. This mix of ageing lead and cast iron pipework, flat-roofed extensions, and converted flats stacked above one another means hidden leaks travel easily between floors before anyone notices a problem.

Common leaks in Merton homes

Converted flats and leaks between floors

Many Victorian terraces in South Wimbledon and Colliers Wood have been split into flats, often with a bathroom built directly above a neighbour's kitchen or lounge. A failed shower tray seal or slow pipe joint can soak through the floor structure for months, showing up as a stain or bulging ceiling below long before the upstairs occupant realises anything is wrong.

Flat roof extensions prone to slow water ingress

Rear and side return extensions are common across Merton's terraced streets, particularly in Merton Park and Wimbledon Chase, and many carry flat or low-pitch roofs. Perished felt, cracked flashing or blocked outlets let rainwater seep in gradually rather than pour through, so damp patches and sagging plasterboard often appear well after the covering has actually failed.

Ageing pipework in 1930s semis and estates

The semi-detached housing stock around Morden, Raynes Park and St Helier dates largely from the interwar period, with original or partially replaced plumbing runs beneath solid floors and within cavity walls. Corroded joints and perished washers can leak steadily into the sub-floor void, and because the water has nowhere visible to go, it is often the flooring or a musty smell that gives the fault away.

What our customers say

Excellent
Rated 5.0 / 5 based on 21 reviews on
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.
