Sand mastic for homes and businesses in Newtonmore
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 older homes, it suits the building far better than silicone. We work on timber door frames, period & listed homes and tenement windows, and people most often call us about gaps where the frame meets the masonry and cracked mastic round a front door frame.
Many older Scottish homes still have timber windows set into stone walls. 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 in Newtonmore and across Highland.

What sealant work cannot fix
In fairness, there are a few things sealant won’t fix:
- Timber that has rotted
- Sash cords, weights and draught-proofing of the sashes
- Broken panes

What the job involves on each surface
Timber door frames
Doors face weather and wear and the mastic can crack early. It’s renewed by hand.
Stone surrounds
Stone openings are rarely perfectly straight, so the joint varies in width. We shape it by hand to follow the stone.
Why it’s worth doing now in Newtonmore
Silicone might seem the quicker option, but on period stone or brick it often looks out of place. Sand mastic suits the building and blends with the stone or brick. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water behind a failed seal does the most damage when nobody’s watching.
Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs. Call for a quick quote and we’ll go through it with you.

Common problems we fix in Newtonmore
Shallow joints are a common cause. A thin layer does not hold well so we make sure the new mastic is the right thickness.
If you can see any of these, it’s time to have the joints looked at:
- Mastic dropping out of the joint
- Gaps where the frame meets the masonry
- Silicone on a period window that looks wrong
- Old cement repairs round a window that have failed
Around Newtonmore, as everywhere, sand mastic is only as good as the preparation behind it.

Frames and glazing around Newtonmore
Many older homes in Scotland have sash and case windows, often pointed into the wall with traditional sand mastic. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that.
Letting a property close to Newtonmore station? Then older sash windows in a rental need their mastic kept sound to keep the weather out.

How the visit works
Once we are on site, we check the joints match what you told us. If anything is different, we explain it before carrying on. After that, the work takes a few hours for a single window, longer for several. In smaller Scottish places, parking is normally less of an issue than access and distance. Let us know how to find you and how to reach the joints, and the visit is planned around that.
- 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
- Mention any sign-in or site rules at work premises
- Tell us about access, such as stairs, a lift or high-level joints
- Let us know about earlier repairs to the joints
How to get a quote
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is, and we will explain how we’d tackle it. Whenever you’re ready, send an email to info@mrmastic.co.uk.
Advice
Other services in Newtonmore
Keeping the joints in good condition
Good habits help new joints last longer. A few tips:
- Keep sills and gutters clear so water drains away
- Get any rot dealt with first
- Do not paint over the new mastic
- Take care around the mastic when scraping paint
Keep gutters and sills clear so water runs away from the surround. Water sitting against the mastic shortens its life.
It’s best to renew mastic before painting the windows. Paint over cracked mastic only covers it up.
Work for landlords, hotels and businesses
Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. We can quote for more than one property at once.
From a single let to a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.

No, it will not last. It may look fine at first, but the new bead soon lifts. The old sealant has to come out completely.
