Mastic man in Northfleet

Sealant jobs we do in Northfleet

Northfleet runs along the Thames immediately west of Gravesend, and for two centuries its riverside was given over to cement works, a shipyard and heavy industry. The last cement plant closed in 2008, and the old industrial land is now becoming new housing as part of Ebbsfleet Garden City. Mr Mastic covers Northfleet from our base in Crawley, resealing bathrooms and kitchens and renewing mastic around windows and doors in old and new homes alike.

On a brand-new flat or a hundred-year-old terrace, we never just add another line of silicone. The old sealant is cut out, the joint cleaned of mould and soap and left dry, and a new bead goes on that fits the gap. Our article on how long silicone sealant lasts explains why even good joints need renewing in time.

From cement-town terraces to a riverside new town

Much of Northfleet’s older housing went up as the cement industry grew through the nineteenth century, and flint walls can still be found in the area. Rosherville takes its name from a building scheme that began with new houses in 1830, and Perry Street, once a separate hamlet, is now fully built up. In older terraces, bathrooms are often in a rear extension or a converted bedroom, and the bath may sit on a timber floor that moves. That movement tears a stiff seal, so we use flexible sanitary silicone laid with the bath full.

The biggest change is on the river. Harbour Village is being built by Bellway on the site of the former Northfleet Cement Works, with 532 homes mixing one- and two-bedroom flats with two- to four-bedroom houses. Further east, the former Henley cable works at Cable Wharf is being redeveloped for housing. New homes like these settle in their first years, and the sealant around baths, trays and kitchen worktops often splits early. Our new build mastic page explains what we check.

Further south, Northfleet Green, Nash Street and Istead Rise have more suburban houses, where the usual jobs are tired bath seals and hardened window mastic.
