Mastic and sealant work in Peacehaven
Few towns on the south coast are laid out like Peacehaven. Founded by Charles Neville in 1916 and renamed Peacehaven in February 1917, it was planned on an American-style grid, with Roads running east to west and Avenues running north to south across the South Coast Road, now the A259. The result is a town of homes built plot by plot, each a little different, sitting on chalk cliffs high above the Channel.
Mr Mastic covers Peacehaven from our base in Crawley. We reseal baths, showers, kitchens and basins, renew the mastic around windows and doors, and seal external joints that take the full force of the coastal weather. Everything starts with the old sealant coming out completely, because a new bead laid over a failed one will not hold.
Built plot by plot on the cliff top
Peacehaven grew out of the plotlands movement, when families from the cities bought small plots and put up simple homes for weekends and holidays. Some of the earliest were old railway carriages, and others were former army huts brought over from North Camp near Seaford. A few of those huts still survive, recognisable by their oblong shape, usually end-on to the road, with outer walls of concrete block. Once services reached the plots, owners began building more substantial houses, and roads were paved from the late 1950s, starting at Telscombe Cliffs and working east.
That history means almost every house here has been extended, rebuilt or altered at some point, often by different owners in different decades. For sealant, that brings joints between old and new walls, extensions with their own windows and roof lines, and bathrooms fitted into spaces that were never planned for them. Newer housing has been added too, alongside the listed Halcombe Farm House and Hoddern Farm House.
Inside, we often find several layers of old sealant, or a bath that has dropped slightly on a timber floor. We strip it all back and reseal with flexible sanitary silicone. Our silicone removal page explains why getting the old bead out properly matters so much.
Forty metres up and nothing between you and the sea
Peacehaven sits on fairly flat land above chalk cliffs around 40 to 50 metres high, with no shelter from the south. Wind-driven rain and salt spray hit window frames, door thresholds and render joints hard, and the strong summer sun on south-facing frames dries external mastic out sooner than it would inland. Once a joint opens, rain is pushed in behind the frame and shows up as damp on the reveal inside.
Outside, we cut out cracked or shrunken mastic, clean back to sound brick or render, fit backing rod where the gap is deep and use a durable, weatherproof sealant. On low houses most frames can be reached from the ground or a short ladder, so the work is usually quick. Our external joints page covers the other places we seal.
Shops, schools and holiday-home owners
The Co-operative Meridian Shopping Centre is Peacehaven’s main retail hub, and the town also has cafés, pubs, restaurants and a leisure centre. Peacehaven Community School and the primary schools at Peacehaven Heights, Meridian and Telscombe Cliffs all have washrooms that need resealing from time to time, and out-of-hours working can be arranged for commercial jobs.
We also work for landlords and owners of rented homes. Between tenancies is the best time to reseal, as the bathroom can be left alone while the silicone cures.

Questions we’re asked in Peacehaven
Do you cover all of Peacehaven?
Yes. We cover North, West and East Peacehaven, the Roads and Avenues either side of the A259, and neighbouring Telscombe Cliffs and East Saltdean.
Why does the mastic on my sea-facing windows crack so fast?
Peacehaven is high and exposed, so sun, wind and salt spray dry out old mastic until it can no longer move with the frame. A flexible, weatherproof replacement lasts much better.
My house has been extended a few times. Can you seal where old meets new?
Yes. Joints between older walls and extensions move slightly, so we use a flexible sealant and backing rod where the gap is deep.
Damp keeps appearing beside my window inside. Could it be the outside sealant?
Often it is. Rain driven into a cracked joint gets behind the frame. We check the outside mastic and the sill joint and replace what has failed.
Can you reseal a bath on a timber floor that moves?
Yes. We fill the bath before sealing so the bead is laid at its heaviest, and use a flexible sanitary silicone.
Do you work for landlords in Peacehaven?
Yes. We reseal between lets and can quote for more than one property at a time.
Do I need to be in while you work outside?
Not always, as long as we can reach the frames safely. We will agree access with you when we quote.
