Mastic man in East Grinstead

Sealant jobs we do in East Grinstead

East Grinstead is a short run east of Crawley, where Mr Mastic is based, so we cover the town and nearby villages such as Felbridge regularly. We reseal baths, showers and basins, renew sealant around toilets and kitchen worktops, and replace failed mastic around windows, doors and external joints.

Most calls start with mould. A shower seal that was white a year ago is now speckled grey or black, and bleach no longer shifts it. That’s because the mould has grown into the silicone itself. The only lasting fix is to take it all out, treat and dry the joint and reseal. Our article on why sealant goes mouldy explains what’s happening.

We look at the whole room while we’re there. A basin splashback, the edge of a bath panel or the joint where a screen meets the tray can all be failing quietly, and it’s easier to put everything right in one visit than to come back for each joint in turn.

Medieval High Street, Victorian villas and modern estates

The High Street has one of the longest continuous runs of 14th-century timber-framed buildings in England, and the conservation area around it holds more than 80 listed buildings, including Sackville College, the sandstone almshouse built in 1609. Many of these old buildings now have flats above shops. Timber frames move with the seasons and rarely give a square corner, so a bath or shower seal needs to be flexible and tooled to the shape of the wall rather than to a ruler.

Away from the centre, the town has Victorian and Edwardian houses, later 20th-century estates and newer developments. Some larger historic buildings have been converted, such as the former St Margaret’s Convent, designed by G.E. Street and now apartments. In conversions, bathrooms often sit over someone else’s ceiling, so we take extra care with tray corners and screen ends.

In family homes from the 1960s onwards, the jobs are familiar: bathrooms refitted once or twice with layers of old sealant left behind, and replacement windows whose perimeter mastic has hardened. Where a previous repair has gone wrong, our remedial sealant service puts it right.
