About our sand mastic in Sayers Common
Sand mastic is the traditional way to point the gap between a timber window frame and the stone or brick around it. It’s made from sand and a linseed-oil-based binder, applied by hand. On period homes, it looks right where silicone wouldn’t. We work on period & listed homes, stone surrounds and brick reveals, and people most often call us about a silicone bead on a sash window that spoils the look and wind and rain getting in round a sash window.
Somewhere as small as Sayers Common, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.
Whatever the size of the job, it’s backed by our one-year guarantee in Sayers Common and across West Sussex.

Should I try it myself first?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
What sealant work can’t fix
Some problems need a builder, plumber or other trade rather than us:
- Broken panes
- Timber that has rotted
- Sashes that need overhauling
If in doubt, phone 0345 464 0079 or drop us an email and we will say what we think before booking.

Leave it or put it right?
Gaps round a sash window let in rain and draughts. Water can get to the frame and the masonry, so dealing with it now protects both. In a small place like Sayers Common, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.

Signs you need sand mastic in Sayers Common
Some old mastic was never deep enough. A thin layer doesn’t hold well, which is why we pack deep voids first and get the depth right.
If you can see any of these, it’s time to have the joints looked at:
- Old cement repairs round a window that have failed
- Modern sealant on a period surround
- Mastic worn away on windows facing the weather
- Mastic dropping out of the joint
If you live in an older home near Christ Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
