Mastic and sealant work in Steyning
Steyning is a small Sussex town with a very long history. It had a market, a royal mint and a church before the Domesday Book, and it sits at the north end of the River Adur gap in the South Downs, about four miles north of Shoreham-by-Sea. The town still has old timber-framed buildings alongside later ones, and that mix of ages shapes the sealant work we do here.
Mr Mastic covers Steyning from our base in Crawley. We reseal baths, showers and kitchens in homes of every age and renew failing mastic around windows and doors, matching the product and finish to the building. With old houses especially, the aim is a neat, flexible joint that keeps rain out without looking out of place.
Timber frames, Victorian brick and later homes
The 2001 census counted 2,530 households in the town. Some live in properties that are centuries old, and the High Street includes listed buildings such as the Old Town Hall at 38 High Street, built in 1886, and the Grade II listed Norfolk Arms. Just across the parish boundary in Bramber, St Mary’s House is a timber-framed house built around 1470, which shows how far back the local building tradition goes.
Older buildings rarely have straight lines. Frames have twisted, walls have moved and gaps around windows vary along their length. Stiff modern mastic pulls away from joints like that, so we use flexible sealants and tool them by hand. For traditional timber windows, a sand mastic finish can suit better than a smooth silicone bead; our guide to sand mastic on sash and case windows explains why.
Many Steyning homes are more recent, and in those the jobs are familiar ones: bath and shower seals that have gone black, basins that have come away from the wall, and uPVC frames whose mastic has hardened.
Old streets, small bathrooms and listed fabric
Older houses and cottages often have small bathrooms fitted into spaces that were never designed for them, with sloping floors and uneven walls. Getting a good seal around a bath or shower tray there means removing every trace of the old sealant, building up deep gaps properly and finishing a bead that can cope with movement. Our bathroom resealing page covers how we do it.
If your home is listed, check with Horsham District Council before changing anything to its windows. Resealing an existing joint is usually routine, but we will always use a sealant and colour suited to the original materials, and we work carefully around old timber, brick and render.
High Street pubs, shops and the grammar school
Steyning has a good spread of businesses for its size: the Star Inn, the Chequer Inn and the White Horse, along with restaurants, cafés and shops, a health centre, a library and a leisure centre. Steyning Grammar School, founded in 1614, now has around 1,950 pupils. Kitchens, toilets, changing rooms and showers in places like these get heavy use, and we can work out of hours or in school holidays.
We also reseal rented flats and houses for landlords, often in the gap between tenancies.

What we do in Steyning
- Bathroom & kitchen resealing: Bathroom and kitchen joints taken back to a clean, dry surface and finished with fresh anti-fungal silicone that won’t lift.
- Window & door mastic: Window and door mastic that has dried out in the sun replaced with a weather-resistant joint that can move with the frame.
- Commercial & hotel sealant: Hotels, offices, washrooms and welfare areas resealed room by room, with out-of-hours working possible to arrange.

- External & façade joints: Split or perished joints in walls and cladding replaced with exterior sealant designed to stretch with the building.
- New-build mastic & snagging: Failed builder sealant in new homes put right, and plot mastic for developers.
- Floor & skirting joints: Movement joints in tiled and concrete floors, and skirting gaps, sealed so they stay tidy and keep dirt out.
- Regrouting: Crumbling grout in showers and wet areas raked out and refilled, so water stays out of the wall behind.

Questions from Steyning
Do you cover all of Steyning?
Yes. We cover the whole town and the neighbouring villages of Bramber, Upper Beeding and Botolphs, and further out towards Shoreham-by-Sea.
Can you seal around old timber windows?
Yes. We remove the failed material by hand and use a flexible sealant or a sand mastic finish, depending on the window and the building.
My cottage bathroom floor isn’t level. Will a new seal still work?
Yes, if it is done properly. We fill deep or uneven gaps in stages and use a sanitary silicone that can take some movement.
Do I need permission to reseal windows on a listed building?
Like-for-like resealing is usually routine, but you should check with Horsham District Council before changing anything on a listed building.
Can you work at a pub or café on the High Street?
Yes. We can reseal kitchens and toilets early in the day or after closing so you don’t lose trade.
Do you work in schools during the holidays?
Yes. School toilets, changing rooms and kitchens can be booked in for holidays or out-of-hours slots.
Why has my shower seal gone black after a year?
Mould grows where moisture sits on or under the bead. We remove it fully, treat the joint and reseal with an anti-fungal sanitary silicone.
My basin has pulled away from the wall. Can you reseal it?
Yes, once it is firmly fixed. If the basin is loose, it needs securing first; then we remove the old bead and lay a new sanitary silicone joint along the wall and splashback.
