Sand mastic in Sevington
We work across Sevington renewing sand mastic on sash windows and doors. Every joint is cleaned out and filled by hand, finished to suit the masonry. We’re often asked to deal with weathered mastic on the most exposed windows and wind and rain getting in round a sash window, on brick reveals, tenement windows and stone surrounds.
Around Sevington, many homes face open ground, so their windows and doors take the full weather. That exposure dries out and cracks the mastic around frames and sills faster.
All our work comes with our one-year guarantee, wherever you are in Kent.

Landlord and commercial work in Sevington
We also work for property managers and facilities teams in Sevington and across Kent. We can quote a run of properties together, and we are fully insured.
Whether it’s one flat or a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a one-year guarantee.
How the visit works
Every visit runs the same way: we check the joints, protect the area around them, do the work and tidy away. Most jobs take a few hours per window, depending on the condition of the joints. Somewhere like Sevington needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We check the window surrounds and agree which joints need renewing.
- We rake out the old mastic and clean the joint.
- Large voids are packed out first, so the mastic is not too thick.
- We mix the sand mastic and apply it by hand, shaping it to the joint.
- The finish is dressed so it sits neatly against the stone or brick.
Preparing for the visit
- Where the joints are inside, avoid wetting them before we arrive
- Plan for the work area to be out of bounds to pets and children
- Move anything stored near the joints

Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.
What we need to know

When to call us in Sevington
Timber swells and shrinks with the weather. The movement cracks the mastic over time.
The most common problems we see are:
- Old sand mastic that has cracked, crumbled or fallen out
- Mastic worn away on windows facing the weather
- Gaps where the frame meets the masonry
- Tired mastic found when preparing windows for paint
Schools such as Willesborough Junior School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.

Sand mastic in Sevington: local notes
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. With historic houses such as Godinton House (about 3.9 miles north-west) nearby, there’s older building stock in the area around Sevington as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
Homes close to Church of St Mary include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. Letting a property close to Ashford International station? Then older sash windows in a rental need their mastic kept sound to keep the weather out.

How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Keep modern sealant off the mastic
- Ask a joiner to look at soft timber first
- Check the mastic when you check the paintwork
- Make sure water runs off the sill
Leave the new mastic alone while it firms up. It skins over quickly, but takes longer to harden fully.
Crumbling mastic lets rain into the joint. That water can reach the timber frame and the wall so early renewal protects both.
When it is not the sealant
Honest advice matters more to us than a booking, so here’s what sealant can’t fix:
- Putty and glazing repairs
- Planning or listed building consent (your local planning authority decides)
- Crumbling stone or brickwork round the window
Not sure which it is? You can phone 0345 464 0079 or email us and we’ll tell you honestly before booking.
