Mould Removal in Merton

Damp & Mould in Merton’s Housing Stock

Merton splits between Wimbledon's Victorian and Edwardian avenues and the more modest stock of Mitcham and Morden — inter-war semis, the borough's share of the giant St Helier cottage estate, and Victorian terraces along the Wandle valley. The rental market is busiest in Colliers Wood, South Wimbledon, and Mitcham, where converted terraces and aging semis produce a fairly even mix of condensation and fabric-related damp; low-lying Wandle-side streets have a genuine high-water-table component.
