Sand mastic for homes and businesses in Balmore
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 period homes, it looks right where silicone wouldn’t. We work on tenement windows, sash and case windows and brick reveals, and people most often call us about a silicone bead on a sash window that spoils the look and draughts and rain around sash boxes.
Older stone-built homes in Scotland often have sash and case or timber windows set in stone. Those suit a traditional sand mastic or a neutral-cure sealant, not an acetoxy silicone that can attack some stone.
Our work is backed for twelve months, in Balmore and everywhere else we cover.

Should I try it myself first?
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.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
Common problems we fix in Balmore
Timber swells and shrinks with the weather. That movement opens up the mastic joint little by little.
People normally contact us after spotting something like this:
- Draughts and rain around sash boxes
- Old cement repairs round a window that have failed
- Crumbling sand mastic round a window
- Gaps where the frame meets the masonry
For site and facilities teams at buildings such as Bishopbriggs Academy, larger buildings have plenty of frames, and the mastic around each one ages.

Balmore homes and the weather
Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that. Balmore is in the west of Scotland, which is wetter than the east, which means the mastic around older windows and doors has to cope with a lot of rain.
Rented homes near Bishopbriggs station change hands often, and cracked sand mastic around sash windows lets in the draughts tenants complain about. For an older house near a landmark such as Cadder Parish Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

What to tell us for a quote

- Whether it’s a home or a business
- Whether it has been sealed before
- How many joints, rooms or windows are involved
- How we’d reach the joints
We quote each job on its own, so the first step is telling us about yours. Simply send an email to info@mrmastic.co.uk and describe the job and send pictures if you have them.
How to look after the new joints
Good habits help new joints last longer. A few tips:
- Keep modern sealant off the mastic
- Take care around the mastic when scraping paint
- Get any rot dealt with first
- Inspect the joints round the windows every year or so
Leave the new mastic unpainted, which is the traditional advice. Ask us before any decorating around it.
Once mastic starts to crumble, rain gets in. It can soak into the frame and the surrounding masonry so early renewal protects both.
