Mastic man in Redhill

Resealing and mastic work across Redhill

Redhill is a railway town through and through. It grew up around the Brighton line in the 1840s and still sits at the meeting point of three railway routes, with plenty of commuters, flats and family homes to match. Mr Mastic is based in Crawley, a short drive down the A23, and Redhill is one of the towns we cover most often.

We reseal showers, baths, basins and kitchens, replace tired window mastic and seal external joints. A common Redhill call is a shower that has started leaking through to the room below. Usually the seal has split where the tray meets the wall. Our page on leaking shower sealant explains how to spot it early, and we can put it right with a full strip-out and reseal, never a quick line over the top.

From Warwick Town terraces to lakeside new builds

The town began as a settlement called Warwick Town after a turnpike road was built in 1818, taking the name Redhill in 1856. Its first station opened in 1841, and much of the older housing close to the centre is Victorian and Edwardian, with the Redstone Hill conservation area to the east. In these houses, bathrooms have often been squeezed into small back rooms, and old timber floors flex enough to tear a stiff bead of sealant.

Redhill also has a good share of conversions and flats. In Earlswood, on the town’s southern edge, the former Royal Earlswood asylum has been turned into apartments at Royal Earlswood Park, and more flats have gone up in and around the town centre. In a block of flats, a failed shower seal rarely stays one person’s problem, because the water finds the ceiling below.

Towards Merstham, the Watercolour neighbourhood was built between 2008 and 2012 around lakes and wildlife habitat. Homes of that age often still have the builder’s sealant, which has had years of settling and daily use. Our new build mastic page covers what we look for in newer homes.
