Sand mastic for homes and businesses in Upton Grey
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 and built up by hand. On older homes, it suits the building far better than silicone. Typical jobs include open joints round the window box and mastic round period door frames that has failed, on period & listed homes, brick reveals and timber door frames.
Around Upton Grey, 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.
You’re covered for a year from the day we finish. If there’s a problem with it, please ring 0345 464 0079 or email us.

What we are called out for in Upton Grey
Some old mastic was never deep enough. A thin layer does not hold well so we make sure the new mastic is the right thickness.
The problems people usually mention when they call include:
- Mastic dropping out of the joint
- Patchy fillers round a sash window
- Draughty sash windows at the surround
- Mastic worn away on windows facing the weather
For landlords with property near Hook station, any sash windows need sound mastic to keep draughts and rain out.

Aftercare tips
Once the sealant has cured, a few habits help it last:
- Go gently near the mastic when preparing windows
- Keep modern sealant off the mastic
- Have rotten timber repaired before new mastic goes in
- Find out about consent before window work on a listed home
When preparing windows for paint, take care around the mastic. It can be damaged by heavy scraping.
Crumbling mastic lets rain into the joint. It can soak into the frame and the surrounding masonry so early renewal protects both.
Can I do it myself?
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 fails, we can still redo it.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
