How we handle sand mastic in West Stoke
We renew sand mastic around sash windows and doors in stone and brick. Out comes the old, loose mastic, the joint is prepared and new mastic is shaped by hand. We’re often asked to deal with window mastic to renew ahead of painting and draughts and rain around sash boxes, on period & listed homes, brick reveals and stone surrounds.
Mastic can only go onto a dry, clean joint, so window work in West Stoke is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
All our work is covered by our one-year guarantee.

What is sand mastic?
Sand mastic is a traditional material for pointing round windows and doors. It’s made with sand and a linseed-oil-based binder.
Will it make a mess?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
How long does sand mastic take to harden?
Not straight away. The skin forms first, and the full set comes later, and we’ll tell you what to expect.
Do I need to be at home?
We need access to the joints, so we’ll agree that with you when we book. Indoors, that normally means someone at home.
What information do you need?
Tell us what needs doing and where, with photos by email if possible. We will ask anything else we need to know.
Which products do you use?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We will tell you what we’re using and why.
Why it’s worth doing now in West Stoke
Gaps round a sash window let in rain and draughts. Water can get to the frame and the masonry so renewing it early protects the window. In a small place like West Stoke, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
A failed joint rarely gets cheaper to fix by waiting. If you’re not sure whether it needs doing, phone 0345 464 0079 or send us an email for an honest opinion and a quote.

What sealant work can’t fix
Sealant is not the answer to every problem, and we’d rather say so up front. It won’t solve:
- Decisions on consent for listed homes
- Cracked or broken glass
- Sashes that need overhauling
If you are not sure, just call 0345 464 0079 or email us and we will give you a straight answer before you book.
What we seal
- Timber door frames
- Tenement windows
- Period & listed homes
- Stone surrounds
- Sash and case windows
- Brick reveals
Sand mastic in West Stoke: local notes
Historic houses like West Dean House (about 3.2 miles north-east) are a reminder that the area around West Stoke has older buildings as well as new. 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. 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.
If you look after a building such as Bishop Luffa School, its window and door frames need their mastic kept sound, just like a home’s. Letting a property close to Fishbourne station? Then any sash windows need sound mastic to keep draughts and rain out.

Should I try it myself first?
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly.
Different surfaces, different methods
Stone surrounds
Old stone surrounds are often uneven, so the gap is not the same all the way round. We shape it by hand to follow the stone.
Period and listed homes
Sand mastic is the like-for-like choice for many period homes. If your home is listed, ask your local planning authority about consent.
When to call us in West Stoke
Timber swells and shrinks with the weather. The movement cracks the mastic little by little.
The problems people usually mention when they call are:
- Weathered mastic on the most exposed windows
- Wind and rain getting in round a sash window
- Old cement repairs round a window that have failed
- Window mastic to renew ahead of painting
For an older house near a landmark such as Church of St Andrew, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
Questions to ask before booking
- Whether they’re fully insured
- How the colour is chosen
- How the surfaces are prepared before sealing
- Who turns up on the day
Aftercare tips
Once the sealant has cured, a few habits help it last:
- Ask a joiner to look at soft timber first
- Check with your local planning authority if your home is listed
- Keep modern sealant off the mastic
- Go gently near the mastic when preparing windows
Don’t run silicone over the new mastic. If anything cracks, get it looked at rather than patching it.
Small cracks are a sign the mastic is ageing. Renewing it then is simpler than waiting until it falls out.
What happens on the day
We work through the job in order: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours per window, depending on the condition of the joints and we leave things clean and tidy. For a village or hamlet like West Stoke, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- We look at the surrounds with you and agree the joints to renew.
- Old mastic and any loose material are raked out.
- We pack any deep voids first.
- The sand mastic is mixed and pressed into the joint by hand.
- The surface is finished to suit the stone or brick.
Getting ready for the visit
- Mention if the joints have been sealed before
- For indoor joints, keep the area dry beforehand if you can
- Keep pets and children clear of the area while we work
