About our sand mastic in Bekesbourne
Sand mastic is the traditional way to point the gap between a timber window frame and the stone or brick around it. It’s a mix of sand and a linseed-oil-based binder, applied by hand. On period homes, it looks right where silicone wouldn’t. If you have cracked mastic round a front door frame and gaps where the frame meets the masonry, we can put it right, on timber door frames, stone surrounds and tenement windows alike.
Homes in small places like Bekesbourne often stand in the open, with little to shelter their windows from wind and rain. That exposure dries out and cracks the mastic around frames and sills faster.
Every job comes with a 12-month guarantee.

DIY versus a professional finish
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Frames and glazing around Bekesbourne
With historic houses such as Goodnestone Park (about 3.3 miles east) nearby, there’s older building stock in the area around Bekesbourne as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you let a flat or house near Bekesbourne station, cracked sand mastic around sash windows lets in the draughts tenants complain about. Homes close to Church of St Peter include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame.

How to look after the new joints
Aftercare is simple:
- Check with your local planning authority if your home is listed
- Look over the window mastic once a year
- Have rotten timber repaired before new mastic goes in
- Clear gutters so water doesn’t pour onto the windows
Look at the mastic when you look over the windows. Small cracks are easier to deal with early.
Sound mastic protects the frame. Failed mastic lets water reach the timber, which can lead to rot.

Advice
Why it’s worth doing now in Bekesbourne
Gaps round a sash window let in rain and draughts. Left, water can reach the timber and the wall, so dealing with it now protects both. In a small place like Bekesbourne, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Doing several joints on one visit is normally more efficient than separate visits, so tell us about everything that needs sealing. We will give you a clear price for the lot.

Bekesbourne: your questions answered
Can you do sand mastic in Bekesbourne?
Yes. Our work covers London and the South East, and Bekesbourne is part of that. You can ring 0345 464 0079 or send us an email and tell us what needs doing.
I let a flat near Bekesbourne station. Can you help?
Yes, we work for letting agents and landlords. Just call 0345 464 0079 or drop us an email and tell us about the property, and we will give you a clear quote.
Do you remove the old sealant?
Yes, every time. New silicone doesn’t stick to old silicone, so the joint is cleaned back first.
Can you seal over the old sealant?
No, because it fails. We remove every bit of old sealant first, so the new joint bonds to clean surfaces.
Can I paint the new mastic?
It’s traditionally left unpainted, which is what traditional guidance recommends. Ask us before decorating.
Is the work guaranteed?
All our work has a 12-month guarantee.
Will there be a smell?
That depends on the sealant. Some products have a noticeable smell, others very little.
How long does sand mastic take to harden?
It skins over fairly quickly but takes longer to harden fully. We’ll tell you what to expect for your job.
Common problems we fix in Bekesbourne
Decorating can disturb tired mastic. It’s often found when windows are being prepared for paint, which is a good time to renew it.
Signs it’s time to call us include:
- Crumbling sand mastic round a window
- Open joints round the window box
- Tired mastic found when preparing windows for paint
- Failed mastic on an exposed elevation
If you look after a building such as St. Anselm's Catholic School, larger buildings have plenty of frames, and the mastic around each one ages.

- Whether VAT is included
- How long to leave it before use
