Mastic man in Merton

Your local mastic man for Merton

Mr Mastic is a mastic and silicone specialist based in Crawley, and the London Borough of Merton is one of the areas we cover. We take out stained, peeling or cracked sealant and replace it with a clean, durable bead: around baths and shower trays, along kitchen worktops and basins, at the foot of the toilet and around windows, doors and the outside of the house.

Merton has a bit of everything, from tall Victorian houses in Wimbledon to interwar semis in Morden and big council-built estates on the borough’s southern edge. A good reseal looks the same in all of them: old material fully removed, the surface cleaned and dried, and the right sealant applied in one smooth line. If your bath seal keeps going black or coming away from the tiles, that’s usually a sign the last job skipped one of those steps.

Wimbledon terraces, Morden semis and the St Helier estate

The north and west of the borough are the oldest parts. Wimbledon, Wimbledon Park, Raynes Park and Merton Park are mostly Victorian and Edwardian houses, and the council protects many of these streets: there are 29 conservation areas in Merton, among them Wimbledon Village, Wimbledon North, Wimbledon Hill Road, Wimbledon West and the John Innes areas in Merton Park. Older houses move with the seasons, so we use flexible sealants on bathrooms fitted against old walls and around period window frames.

Morden is different. After the Underground arrived in 1926, a new suburb grew up around the station, mostly semi-detached houses with gardens, with mansion blocks along the main roads. Many of these homes now have their second or third bathroom, and the sealant around baths that were fitted on timber floors often tears as the bath flexes.

To the south, the London County Council built the St Helier estate between 1928 and 1936, part of it in Morden and part in neighbouring Sutton. Mitcham, with its Cricket Green conservation area, adds its own mix of older and newer homes. Across all of these, we see the same pattern: bathrooms resealed in a hurry, over old silicone, which fails within months.
