Sand mastic for homes and businesses in Fettercairn
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. We work on period & listed homes, stone surrounds and timber door frames, and common reasons people get in touch are gaps between timber frames and stone or brick and old cement repairs round a window that have failed.
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.
Whatever the size of the job, it’s backed by our 12-month guarantee.

Common problems we fix in Fettercairn
Shallow joints are a common cause. A thin layer doesn’t hold well so we make sure the new mastic is the right thickness.
Keep an eye out for these signs:
- Draughts and rain around sash boxes
- Cement or filler used on old window joints that has cracked
- Gaps where the frame meets the masonry
- Gaps round a timber door in stone or brick
Homes close to Fettercairn Parish Church include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
Questions to ask before you book

What happens if it’s left?
New mastic over crumbling mastic won’t hold. We remove the loose material first so the new mastic stays put. Exposed walls in smaller Scottish places take a lot of wind and rain, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether the work is at height. Your quote takes all of that into account.
What you get with us
- Experience in homes, commercial sites and hotels
- Anti-fungal silicone where joints get wet
- One-year guarantee on every job
- Any old sealant cut out fully, not covered over
Surface by surface
Tenement and terrace windows
Rows of sash windows on tenements and terraces often need renewing together. We work on single windows or whole elevations.
Stone surrounds
We take care not to mark the stone while raking out the old mastic.
The process
When we get to you, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours per window, depending on the condition of the joints. Outdoor work around Fettercairn depends on the weather, as sealant needs a dry surface, so an outdoor job can move if the forecast changes. Indoor work goes ahead whatever the weather.
- We check each window surround and the condition of the joint.
- The joint is raked out and cleaned.
- We fill deep gaps so the new mastic isn’t too thick.
- New sand mastic is applied and shaped by hand.
- The finish is dressed neatly.
How to prepare
- Clear items away from the joints we’re working on
- Keep children and pets away from the work area
- Let us know if you’ve seen damp or leaks
Getting a quote
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and email photos if that is easy.

What sand mastic looks like in Fettercairn
Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that. Many older homes in Scotland have sash and case windows, often pointed into the wall with traditional sand mastic.
For landlords with property near Laurencekirk station, cracked sand mastic around sash windows lets in the draughts tenants complain about.

Keeping the joints in good condition
Good habits help new joints last longer. A few tips:
- Ask the planning authority about consent for listed or conservation-area homes
- Look over the window mastic once a year
- Do not paint over the new mastic
- Keep sills and gutters clear so water drains away
Leave the new mastic alone while it firms up. It skins over quickly but needs longer to fully harden.
Sound mastic protects the frame. Once it fails, water can sit against the timber and timber that stays wet can rot.

Yes. We work in offices, washrooms, hotels and other commercial premises. Working times can be discussed when we quote.
What we can’t put right
