Mastic and sealant work in West Kingsdown
West Kingsdown sits on high ground above the Darent valley, along the A20, in Sevenoaks District, with Swanley about five miles to the north-west and Sevenoaks a little further to the south-west. It is a village of around 6,000 people, much of it built in the 20th century. Mr Mastic covers West Kingsdown from our base in Crawley, resealing bathrooms and kitchens and renewing the mastic around windows, doors and external joints.
Whatever the house, the method is the same. Old sealant is cut and scraped out completely, mould is treated, the joint is cleaned and dried, and a new bead is laid in a product that suits the surface and the room. Silicone laid over silicone always fails, so we never do it. If you’re trying to work out who to call, our guide to choosing a mastic man sets out what to ask.
From smallholdings to a commuter village
For centuries Kingsdown was a scattered farming community, and its church, St Edmund King and Martyr, is first mentioned in 1287. After the First World War the land began to break up into holiday homes, shacks, garages and smallholdings, and as London commuters arrived the village grew, mostly on the north-east side of the A20. By the 1980s it was home to around 5,000 people.
Later building added cul-de-sacs of family houses and park home estates for older residents, while Knatts Valley and East Hill, to the south-west, are rural housing areas in their own right. The result is a varied village of bungalows, family houses and park homes rather than one uniform estate.
Each brings its own sealant work: extensions where new walls meet old, bathrooms refitted in older bungalows, and park homes, where showers and baths sit on lighter floors that flex more than a solid slab and need a properly flexible seal.
Woodland plots, extensions and a hilltop position
Many homes here sit among trees on large, sloping plots, and the village is on high ground. External joints get shade and damp on one side and sun on the other, and frames under trees collect debris and green growth. We clean back, cut out failed mastic and use a flexible weatherproof sealant, with backing rod where the gap is deep.
Where an extension meets the original house, the join between the two often moves slightly, and both inside and outside the sealant there tends to crack first. In park homes, we take care with access and work tidily in compact bathrooms. On the east side of the village, off Pells Lane, the Grade II listed smock windmill is a reminder that some buildings here need a lighter touch than others. Our anti-mould resealing page explains how we deal with stubborn mould in small, poorly ventilated rooms.
Village shops, schools and rental homes
Shops, takeaways and businesses along the A20 and in the village centre all have kitchens and washrooms that need resealing from time to time, and the primary school on Fawkham Road is best resealed during the holidays. Out-of-hours working can be arranged for commercial jobs.
We also work for landlords and letting agents. Rented homes need sound seals at every change of tenant, and we can quote for several properties together, with a short written note of what we found at each one.

What we do in West Kingsdown
- Bathroom & kitchen resealing: Every joint in the bathroom and kitchen, from the bath edge to the worktop, stripped back and resealed with anti-fungal silicone.
- Window & door mastic: Hardened, gappy mastic around frames, sills and French or patio doors cut out and renewed to keep draughts and rain out.
- Commercial & hotel sealant: Commercial washrooms, kitchens and wet areas resealed floor by floor, so only a few rooms are out of use at once.
- Remedial sealant & repairs: Messy, layered or wrong-product sealant cut out and replaced with the right sealant, laid the right way.
- Fire-rated sealant: Fire-rated sealant for service penetrations and frame gaps where it has been specified, applied to the tested details.
- External & façade joints: Expansion joints in brick, render and cladding cut out and renewed at the right depth so they can move without splitting.
- New-build mastic & snagging: Snagging sealant for new homes and plot-by-plot mastic for builders and developers.
- Floor & skirting joints: Gaps under skirting boards, tile movement joints and concrete floor joints sealed with a product that suits the traffic.
- Regrouting: Crumbling grout in showers and wet areas raked out and refilled, so water stays out of the wall behind.
- Glazing & conservatory sealant: Conservatory, rooflight, glass panel and shower screen joints resealed with glazing silicone.
- Gutter, fascia & soffit sealing: Exterior joints at gutters, fascias and soffits resealed to stop drips and staining down the wall.

Do you cover all of West Kingsdown?
Yes. We cover the whole village on both sides of the A20, including Knatts Valley and East Hill, and nearby Swanley and the Sevenoaks area.
Can you reseal a shower in a park home?
Yes. We use a flexible sanitary silicone suited to the lighter floors in park homes, and work tidily in small bathrooms.
The sealant where my extension meets the house keeps cracking. Can you fix it?
Yes. That joint moves, so we cut out the old sealant and use a flexible product, with backing rod where the gap is deep.
Our window frames are under trees and the mastic has gone green. What can you do?
We clean the frame, remove the failed mastic and reseal with a weatherproof product.
Do you reseal kitchens in older bungalows?
Yes. We reseal worktops, sinks and upstands, using food-safe sealant where needed.

Yes. We reseal between tenancies and when tenants report mould or leaks.
Can you reseal a bathroom in a chalet bungalow with a sloping ceiling?
Yes. Awkward corners, short walls and baths tucked under the eaves are common in older village homes, and we work around them neatly, cutting the old bead out by hand where a tool won’t reach.
