Skinflats Sand Mastic
Sand mastic for Skinflats, by sealant specialists with 20+ years’ experience. Rated 4.9 on Google from 180+ five-star reviews.
- Old sand mastic that has cracked, crumbled or fallen out
- Gaps where the frame meets the masonry
- Silicone on a period window that looks wrong
Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. A few tips:
- Make sure water runs off the sill
- Get any rot dealt with first
- Check the mastic when you check the paintwork
- Go gently near the mastic when preparing windows
Avoid sealing over the mastic with silicone. If you see a crack, ask us to take a look before trying a quick fix.
Once mastic starts to crumble, rain gets in. That water can reach the timber frame and the wall, so renewing it early is worth it.
Sand mastic for homes and businesses in Skinflats
Sand mastic does not last for ever and gaps open up round the frame. We rake it out and renew it and tidies the surround. Typical jobs include gaps between timber frames and stone or brick and mastic round period door frames that has failed, on period & listed homes, timber door frames and brick reveals.
Older stone-built homes in Scotland often have sash and case or timber windows set in stone. The sealant has to suit the stone, which rules out acetoxy silicones that can mark or attack it.
You get a one-year guarantee, the same in Skinflats as everywhere else we work.

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 does not work out, we can still put it right.
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so just mention it when you contact us.
Different surfaces, different methods
Period and listed homes
A traditional finish suits a period property, and sand mastic is one of them.
Brick reveals
Gaps between frame and brick let in rain and draughts. Renewing the mastic closes it.
Questions from Skinflats
Is sand mastic in a coastal place like Skinflats any different?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.

Yes, Skinflats is covered. We work across all of Scotland, from towns to the smallest places. Longer journeys are simply planned in advance.
Where are you based?
Our base is Crawley. We work across South East England, London and Scotland.

What sand mastic looks like in Skinflats
Skinflats is within about 2 miles of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on the mastic around older windows and doors, which can dry out and crack sooner where a building faces the weather. 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.
Letting a property close to Falkirk Grahamston station? Then any sash windows need sound mastic to keep draughts and rain out.
