About our sand mastic in Beare Green
Old sand mastic cracks, crumbles and falls out over time and gaps open up round the frame. We rake it out and renew it and tidies the surround. We’re often asked to deal with old sand mastic that has cracked, crumbled or fallen out and draughty sash windows at the surround, on sash and case windows, timber door frames and stone surrounds.
Around Beare Green, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.
Your job is guaranteed for a year, as with all our work.

The process
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours for a single window, longer for several, and the area is left clean. Somewhere as small as Beare Green, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- Each surround is checked first.
- The joint is raked out and cleaned.
- Large voids are packed out.
- We point the joint with sand mastic by hand.
- The finish is dressed neatly.
How to prepare
- Mention if the joints have been sealed before
- Mention any sign-in or site rules at work premises
- Tell us about any water getting in

How to look after the new joints
Simple care keeps the joints in good condition. Our advice:
- Ask a joiner to look at soft timber first
- Don’t run silicone over sand mastic
- Go gently near the mastic when preparing windows
- Find out about consent before window work on a listed home
Keep gutters and sills clear so water runs away from the surround. Constant wetting wears the mastic faster.
Gaps round a sash box let in draughts and rain. The longer it’s left, the more the joint opens.
Beare Green questions
Will you come out to Beare Green?
Yes. Beare Green is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Can you help a landlord with a rental near Holmwood station?
Yes, landlords and agents are among the people we work for. Just ring 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll give you a clear quote.
Where are you based?
We’re based in Crawley, West Sussex, and we work across South East England, London and Scotland.
Can you match the sealant colour?
We help you choose a colour that suits. The product needed can limit the range.
What do you need from me for a quote?
Only a few details: the address or postcode, what’s wrong and any access issues. Then call 0345 464 0079 or email us.
What’s sand mastic made of?
A traditional pointing material made from sand and a linseed-oil-based binder for the joint between timber frames and masonry.
Can old silicone round a sash window be swapped for sand mastic?
Often, yes. With the silicone removed and the joint cleaned, sand mastic is applied by hand.
Can I paint the new mastic?
Sand mastic is normally left unpainted, as guidance on traditional windows advises. Talk to us before any painting near it.
Should I try it myself first?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
Work for landlords, hotels and businesses
We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements and we will quote.
Landlords and letting agents in Beare Green can book us as well as homeowners. Sealant work between tenants is a simple way to keep a property in good order.
What happens if it’s left?
A silicone bead can be quicker, but on period stone or brick it often looks out of place. Sand mastic suits the building and blends with the stone or brick. Where a wall is exposed, as many are in small places like Beare Green, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. You will know the price before we begin.

Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For landlords with property near Holmwood station, older sash windows in a rental need their mastic kept sound to keep the weather out. For an older house near a landmark such as Church of St Mary Magdalene, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. For site and facilities teams at buildings such as The Weald CofE Primary School, its window and door frames need their mastic kept sound, just like a home’s.
