Your local mastic man for Banstead
Banstead sits high on the North Downs in the borough of Reigate and Banstead, with the open slopes of Banstead Downs to the north and Banstead Heath and Burgh Heath to the south. Its housing is mostly low density and set among a lot of green space, and the town is largely made up of family homes that have been lived in, improved and refitted for decades. Mr Mastic covers Banstead from our base in Crawley, a short drive up the A217, and we reseal baths, showers, basins and worktops, and renew the mastic around windows and doors.
A good reseal starts with taking the old bead out completely. We cut and scrape away every trace of the failed sealant, treat any mould that has crept underneath, let the joint dry, and only then run a fresh bead with a product suited to the job. If your bathroom sealant keeps turning black within a year, our article on why sealant goes mouldy explains what is usually behind it.
Interwar estates, detached houses and High Street flats
Banstead stayed a small downland village until the late nineteenth century, when better roads and the railway brought gradual growth. The big change came between the wars. Nork, on the west side of the A217 around Banstead station, was a newly built estate by the mid-1920s, when its first residents formed an association to press for made-up roads and street lighting. Further building followed around Banstead Village in the early 1930s, and the middle of the century added some low-density council housing.
The result is a town of mainly detached and semi-detached houses. At the 2011 Census, Nork ward had more than 1,600 detached homes and fewer than 200 terraced ones, while Banstead Village ward had a far larger share of flats, over 900 of them. Some of those flats are new: the old Council House was partly demolished in 2002 and rebuilt as the Holmewood House apartments, keeping its original frontage.
In the older family houses, bathrooms and kitchens have usually been replaced two or three times, and we often find sealant laid over sealant, baths that have dropped slightly on their feet, and worktop joints that have opened up. Replacement uPVC windows from the 1990s and 2000s are now reaching the age where the external mastic is hard, cracked and pulling away from the brick.

Hilltop houses and flats near the village centre
Being up on the Downs means Banstead’s houses catch the wind and the weather, and the joints around windows, patio doors and render stops work hard. We cut out the old exterior mastic, clean back to sound brick or render, add backing rod where a gap is deep, and finish with a flexible, weatherproof sealant. Our external joint sealing page covers the details.
In the flats around the High Street and in newer blocks like Holmewood House, the concern is usually the neighbour below. A tired shower seal can let water track under the tray for months before a stain appears on the ceiling downstairs. We can arrange access through a managing agent, and the town centre gets busy, so we plan parking before we arrive.
High Street shops, schools and lettings
Banstead High Street runs from the war memorial to the library and is lined with independent shops, cafés, restaurants, estate agents and solicitors’ offices. Staff toilets, kitchenettes and café prep areas all need sound sealant to pass inspection and stay hygienic, and we can work before opening or after closing so trading is not interrupted.
With six estate agencies in the town, there is a steady lettings market, and landlords often call us between tenancies or when a tenant reports mould. We also look at washrooms and changing areas for schools, which are best tackled during the holidays.

Questions we’re asked in Banstead
Do you cover all of Banstead?
Yes. We cover Banstead Village, Nork, Burgh Heath and the roads around Banstead Downs and Banstead Heath, and nearby Tadworth and Woodmansterne too.
My 1930s semi has had three bathrooms over the years. Will you take all the old sealant out?
Yes. Every layer comes out, down to clean tile and bath edge, because new silicone will not bond properly to old.
I live in a flat near the High Street and the ceiling below has a stain. Could it be my shower?
It often is. A failed seal around the tray or screen lets water creep underneath; we can reseal it, though a leaking pipe would need a plumber.
Can you replace the mastic around my uPVC windows on a windy hilltop road?
Yes. We remove the cracked mastic, clean the frame and brickwork and apply a flexible exterior sealant that copes with movement and weather.
Do you reseal for letting agents in Banstead?
Yes. We can reseal between tenancies and quote for several properties at once.
Can you work in a café or shop before it opens?
Yes. Early-morning or evening working can be arranged for commercial jobs.
How soon can I use the bath after resealing?
We will tell you the cure time for the product used, usually around 24 hours before it gets wet.
