Drain Unblocking in Merton — Local Specialists
Merton spans from the affluent streets around Wimbledon Common to the flat, former industrial areas of Mitcham and Colliers Wood. The River Wandle runs through the borough and its flood plain covers parts of Mitcham and Colliers Wood. Victorian and Edwardian terraces are common in Raynes Park and South Wimbledon, with older clay drainage that can block with root intrusion.
Merton is two boroughs in one, and the drainage reflects it. Up in the affluent south and west, the streets around Wimbledon Common, Wimbledon Village and Raynes Park sit on higher, well-drained ground, but the large gardens and commons are full of mature trees whose roots are forever seeking out the old clay pipes beneath Victorian and Edwardian terraces — root intrusion is our most common call here. Down in the north and east, the flatter, formerly industrial land of Mitcham and Colliers Wood sits in the flood plain of the River Wandle, and that low-lying ground holds water and presses on buried drainage, while many old industrial yards were redeveloped without fully replacing their ageing pipe runs.
We cover every corner of the borough — Wimbledon, Morden, Mitcham, Colliers Wood, Raynes Park, South Wimbledon and Motspur Park. Our engineers jet, rod, cut roots and carry out CCTV surveys, and we handle both sides of Merton’s character: clearing root-filled clay drains under the period terraces of Raynes Park and South Wimbledon, and dealing with the slow, silted runs and surface-water issues common on the Wandle flood plain around Mitcham and Colliers Wood.
If your house has a large garden or sits near a common, regular drain maintenance is worth scheduling, because a root-cut now is far cheaper than a collapsed pipe later. And for anyone buying a period terrace, a CCTV survey will show whether the original clay line has been invaded by roots or opened at the joints. Call 020 8050 8258 and we will come out, find the cause and fix it properly.
