Sand mastic for homes and businesses in Weston Turville
Sand mastic has long been used to fill the joint between timber frames and masonry. It’s made from sand and a linseed-oil-based binder, applied by hand. On older homes, it suits the building far better than silicone. We work on brick reveals, period & listed homes and sash and case windows, and common reasons people get in touch are gaps round a timber door in stone or brick and mastic that needs renewing before redecorating.
Homes around Weston Turville range from older properties to newer houses, and their windows range just as widely. Each frame material needs the right sealant against the right wall.
A one-year guarantee comes as standard, so you are not left on your own once the job is done.

Should I try it myself first?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Surface by surface
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.
Stone surrounds
Old stone surrounds are often uneven, so the gap isn’t the same all the way round. Sand mastic is shaped by hand to suit.
The process
There isn’t much for you to do on the day. Show us the job and we will take it from there. The job generally takes a few hours per window, depending on the condition of the joints, including the tidy-up. For a job in Weston Turville, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- We look at the surrounds with you and agree the joints to renew.
- Old mastic and any loose material are raked out.
- Deep gaps are packed so the mastic sits at the right depth.
- The sand mastic is mixed and pressed into the joint by hand.
- We dress the finish so it sits neatly against the masonry.
How to prepare
- Tell us if parking is tricky
- Tell us about access, such as stairs, a lift or high-level joints
- For business premises, tell us about site rules or sign-in

It’s a mix of sand and a linseed-oil-based binder. It’s built up in the joint by hand and shaped to suit the surround.
Can you seal over the old sealant?

Check with your local planning authority. They’ll tell you if consent is needed.
Sand mastic in Weston Turville: local notes
Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Homes close to Church of St Mary the Virgin include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Looking after it afterwards
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Keep modern sealant off the mastic
- Check with your local planning authority if your home is listed
- Do not paint over the new mastic
- Make sure water runs off the sill
Avoid sealing over the mastic with silicone. If you see a crack, ask us to take a look rather than patching it.
An open joint round the box lets weather through. Left, the gap tends to get bigger.
What we can’t put right
In fairness, there are a few things sealant will not fix:
- Whether work needs listed building consent
- Rotten sashes, sills or window boxes (a joiner’s job)
- Cracked or broken glass
