About our sand mastic in Croftamie
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. If you have a silicone bead on a sash window that spoils the look and mastic that needs renewing before redecorating, we can put it right, on tenement windows, sash and case windows and stone surrounds alike.
Across smaller places in Scotland, homes range from stone and harled cottages to newer houses, many standing in the open. Exposed frames and sills take the full force of wind-driven rain, so the mastic there works hard.
There’s a 12-month guarantee on every job.

The process
On the day, there’s very little for you to do. Point us to the joints and we’ll get on with it. The job generally takes a few hours for a single window, longer for several. Somewhere like Croftamie may be a longer drive, and the journey is planned ahead. Mention tracks, gates, ferries or anything else about the route.
- We look at the surrounds with you and agree the joints to renew.
- We remove the old, loose mastic.
- Deep gaps are packed so the mastic sits at the right depth.
- We apply the mastic by hand and shape it.
- We dress the finish so it sits neatly against the masonry.
Preparing for the visit
- Clear items away from the joints we’re working on
- Let us know about stairs, lifts or work at height
- Mention any sign-in or site rules at work premises

What sand mastic looks like in Croftamie
Many older homes in Scotland have sash and case windows, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and sound outside sealant is part of that.
For jobs in and around Croftamie, choosing the right material for each joint is as important as a tidy finish.
Croftamie is about 8 miles north-east of Dumbarton, in Stirling.

Why act early in Croftamie
If you are redecorating, renew the mastic first. Painting over failed mastic doesn’t seal it, and the new mastic is traditionally left unpainted. Out of town in Scotland, exposed walls take a lot of weather, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
What you pay reflects the work, not guesswork. That is why we ask a few questions first and agree the price before starting.

Do you need sand mastic in Croftamie?
Over the years, sand mastic weathers. It hardens, cracks and starts to come away from the frame or the masonry.
It’s worth asking for a quote if you see:
- Window mastic to renew ahead of painting
- Patchy fillers round a sash window
- Mastic round period door frames that has failed
- Old sand mastic that has cracked, crumbled or fallen out
Around Croftamie, as everywhere, sand mastic is only as good as the preparation behind it.

DIY versus a professional finish
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 does not work out, we can still put it right.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Don’t paint over the new mastic
- Go gently near the mastic when preparing windows
- Find out about consent before window work on a listed home
- Have rotten timber repaired before new mastic goes in
Keep paint scrapers and sanders off the mastic when redecorating. Hard scraping can loosen it.
Renewing mastic before redecorating saves doing it twice. Painting over failed mastic hides the problem for a while.
