Sealant jobs we do in Epsom
Epsom is a busy commuter town about 14 miles from central London, with a lot of family homes and a lot of bathrooms. Mr Mastic is based in Crawley and covers Epsom and Ewell, coming up to reseal baths, showers, kitchen worktops and the mastic around windows and doors.
Most calls start the same way: a line of black spots along the bath, a shower tray that has begun to leak into the ceiling below, or window sealant that has cracked and come away from the brick. Whatever the job, we cut out every trace of the old bead, clean and dry the joint and lay new sealant that suits it. If mould keeps coming back in your bathroom, our anti-mould resealing page explains what we change to keep it away for longer.
Spa-town streets, interwar estates and the Horton cluster
Epsom grew slowly after its days as a spa. Housebuilding along Burgh Heath Road, College Road and Worple Road began after the land was enclosed in 1869, and terraces followed in the decades after Epsom Court was broken up in the 1890s. Many of these houses have had their bathrooms refitted two or three times, and we often find several layers of old sealant, or a bath that has dropped slightly on an old timber floor and torn its seal.
The town grew again between the wars, with houses on Chase Road and the Copse Edge Avenue estate from 1928, and around 1,500 council houses built between 1920 and 1939. Interwar semis and council-built homes usually have replacement uPVC windows now, and the mastic around frames fitted twenty or more years ago has often hardened and shrunk.
Then there is Horton, where the Epsom Cluster of five psychiatric hospitals was redeveloped in the early 2000s into around 1,850 homes. Those houses and flats are now old enough that their original sealant is reaching the end of its life. Our guide to how long silicone sealant lasts explains the signs to look out for.

Open Downs and exposed streets
Outside, the town sits below the open chalk of Epsom Downs, with Green Belt on three sides. Houses on the higher, more open streets catch more wind and rain, and frames facing south or west take the full afternoon sun. Mastic on those elevations dries out and loses its grip first. We use flexible, weatherproof sealant outside, with backing rod where a gap is deep, so the joint can move with the frame without splitting.
Schools, the hospital and town-centre offices
Epsom has more institutions than most towns its size: Epsom Hospital on Dorking Road, the University for the Creative Arts campus, Epsom College and several secondary schools, as well as offices such as Atkins, one of the town’s largest private employers. Washrooms, changing rooms and staff kitchens in buildings like these see heavy use, and failed sealant is both a hygiene issue and a leak waiting to happen.
We work with facilities teams, care homes and clinics on resealing with anti-bacterial silicone, and our healthcare sealant page covers how we plan that work. Out-of-hours visits can be arranged, and we also reseal for Epsom landlords between tenancies.

Questions from Epsom
Do you cover Ewell and Stoneleigh as well as Epsom?
Yes. We cover the whole of Epsom and Ewell, including Stoneleigh and the streets around Epsom Common and the Downs.
My home is on one of the former Horton hospital sites. Is it time to reseal?
If the sealant is original, it may well be. Those homes date from the early 2000s, and silicone that old has often shrunk, yellowed or gone mouldy.
Can you reseal a bath in an older Victorian terrace with a timber floor?
Yes. We fill the bath with water before sealing, so the bead is laid with the bath at its lowest and copes better with floor movement.
Do you work in schools or clinics during the holidays?
Yes. Holiday and out-of-hours working can be arranged, so washrooms are back in use when people return.
Will you seal over my old window mastic?
No. New sealant won’t bond properly to old, so we cut out the hardened mastic and clean the frame before applying a fresh bead.
