Chesham Mastic Man: Window Mastic, Bathroom Resealing & More

Old town, steep hills, lots of character

Chesham sits in the Chess valley with houses climbing the hills on every side.

The Old Town around Church Street has timber-framed and brick cottages, while Newtown and Waterside have Victorian terraces with small windows and tight reveals. Up the hills, Chesham Bois, Pond Park and Lye Green have semis and detached homes from the 1930s onwards, many with replacement uPVC windows that are now two decades old.

Builders working on extensions, loft conversions and new homes around the town use us to finish the sealant properly.

Chesham is famous for the Metropolitan line's far end and its brewing and woodware past. Narrow Old Town lanes and steep drives make access tricky, so we bring compact equipment and plan the visit with you.

Showers, baths and en-suites

We remove every trace of the old silicone, kill the mould, let the joint dry and reseal with anti-mould sanitary silicone. It is the only way to stop black mould coming straight back.

Kitchens, wet rooms and utility rooms get the same careful approach.

We are also a sealant contractor and specialist applicator for commercial work: façade and curtain wall sealant, concrete joint sealing, polysulphide where needed, new-build snagging and plot mastic, with RAMS.
