Mastic man in Chatham

Your local mastic man for Chatham

If you’re looking for a mastic man in Chatham, Mr Mastic covers the whole town from our base in Crawley. We reseal baths, showers, basins and kitchen worktops, cut out and replace tired mastic around windows and doors, and seal the external joints that let rain into walls. Jobs range from one mouldy shower tray in a terrace off the High Street to a run of flats that all need doing before new tenants move in.

Every job starts the same way. The old sealant comes out completely, the joint is cleaned back and dried, and only then does a new bead go on. Black spots that keep returning usually mean mould has got underneath the old silicone, and our anti-mould resealing service deals with the cause rather than hiding it for a few weeks.

Dockyard terraces, valley estates and riverside flats

Chatham grew around its Royal Dockyard, founded in the 1560s and closed on 31 March 1984. As the yard drew in workers, streets of Victorian terraced houses filled the ground between the High Street and Luton, once a separate village in the Luton Valley. Many of these homes now have bathrooms fitted into a former back bedroom or a rear extension, often on suspended timber floors that flex as the bath fills. That movement splits stiff, old sealant along the bath edge, and water then finds its way to the kitchen ceiling below.

To the south, Walderslade was mostly countryside until the start of the 20th century, when a speculative builder began its core in Walderslade Bottoms; the area kept growing for decades afterwards. Here we see a lot of replacement uPVC windows and patio doors whose perimeter mastic has hardened, shrunk and come away from the brick.

On the former dockyard land, Chatham Maritime and St Mary’s Island brought a marina and newer housing, much of it flats and townhouses. Newer homes settle in their first few years, and builder sealant in showers and around frames often cracks as a result. Where it has, we cut it out and reseal with a flexible sanitary silicone that copes with the movement.
