Sand mastic in Cousland
Fresh sand mastic forms a skin quite soon but full hardening takes longer. Traditional guidance is not to paint over it, so ask us before you decorate. If you have draughty sash windows at the surround and cement or filler used on old window joints that has cracked, we can put it right, whatever the surface.
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 Cousland as everywhere else we work.

Common questions in Cousland
Will you come out to Cousland?
Yes, Cousland is covered. We work across all of Scotland, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Is Cousland in your area for sand mastic?
Yes, Cousland is within the area we cover. We work across all of Scotland. You can send an email to info@mrmastic.co.uk and tell us what needs doing, and we will give you a clear quote.
Do you work for hotels and businesses?
Yes. Commercial and hotel work is a large part of what we do. We can talk about working times when we quote.
Will you leave a mess?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
Will the old sealant be removed?
Yes. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
Do I need permission for sand mastic on a listed building?
Checking first is sensible. Your local planning authority can say if consent is needed for listed or conservation-area properties.
How do I get a quote for sand mastic in Cousland?
It depends on the job, so we quote each one individually. To get one, email us at info@mrmastic.co.uk with a short description of the job.
Do I have to be there?
That depends on where the joints are. Inside work needs someone to give us access, and for outside work we will agree access with you when we book.
Windows and doors in Cousland
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. 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.

What we can’t put right
We’d rather tell you now than do work that will not last, so here’s what sealant cannot put right:
- Sash cords, weights and draught-proofing of the sashes
- Masonry that needs repairing
- Rotten sashes, sills or window boxes (a joiner’s job)
Not sure which it is? You can email us at info@mrmastic.co.uk and we will tell you honestly before booking.
What we seal
- Sash and case windows
- Tenement windows
- Timber door frames
- Stone surrounds
- Brick reveals
- Period & listed homes
Aftercare tips
No joint lasts for ever, but care makes a real difference. A few tips:
- Ask us before painting near the mastic
- Check the mastic when you check the paintwork
- Go gently near the mastic when preparing windows
- Keep modern sealant off the mastic
Leave the new mastic unpainted, as traditional guidance advises. Ask us before any decorating around it.
Gaps round a sash box let in draughts and rain. The longer it’s left, the more the joint opens.
Why it’s worth doing now in Cousland
Not every filler suits an old window surround. Sand mastic is the like-for-like choice, which can matter on listed and conservation-area homes. Exposed walls in smaller Scottish places take a lot of wind and rain, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs, plus any working-time requirements on site. Call for a quick quote and we’ll explain what it covers.

When to call us in Cousland
Previous repairs in cement or silicone often trap water or crack away. They don’t move with the timber and we normally remove them.
It’s worth asking for a quote if you see:
- Mastic worn away on windows facing the weather
- Open joints round the window box
- Draughty sash windows at the surround
- Patchy fillers round a sash window
For landlords with property near Wallyford station, any sash windows need sound mastic to keep draughts and rain out.
