Sand mastic for homes and businesses in Kirknewton
Burnt sand mastic is a traditional material that sits naturally against stone and brick. It’s a good fit for period properties where a modern sealant bead would stand out. If you’re dealing with mastic that needs renewing before redecorating and weathered mastic on the most exposed windows, we can put it right.
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.
Big or small, you get the same 12-month guarantee in Kirknewton and across West Lothian.

What happens if it’s left?
New sash windows are a major, costly change, and in listed buildings it may need consent. If the frames are sound, renewing the mastic deals with gaps and draughts at the surround. 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.
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.

Looking after it afterwards
So the new joints stay in good condition:
- Look over the window mastic once a year
- Renew mastic before redecorating the windows
- Go gently near the mastic when preparing windows
- Find out about consent before window work on a listed home
When preparing windows for paint, take care around the mastic. It can be damaged by heavy scraping.
Sound mastic protects the frame. Failed mastic lets water reach the timber, which can lead to rot.
What we can’t put right
In fairness, some problems need a different trade:
- Broken panes
- Decayed frames that need repair
- Crumbling stone or brickwork round the window
If in doubt, drop us a line at info@mrmastic.co.uk and we will say what we think before booking.

How the visit works
A visit follows a simple pattern: we check the joints, protect the area around them, do the work and tidy away. It normally takes a few hours per window, depending on the condition of the joints. Somewhere like Kirknewton may be a longer drive, and the journey is planned ahead. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- We check the window surrounds and agree which joints need renewing.
- We rake out the old mastic and clean the joint.
- Large voids are packed out first, so the mastic isn’t too thick.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- We dress the surface so it sits neatly against the masonry.
Preparing for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Keep pets and children clear of the area while we work
- For business premises, tell us about site rules or sign-in

What sand mastic looks like in Kirknewton
Many older homes in Scotland have sash and case windows, often pointed into the wall with traditional sand mastic. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that.
Homes close to Kirknewton Parish Church include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
