How we handle sand mastic in Skelbo Muir
Across Skelbo Muir, we renew sand mastic around sash and case windows. Each joint is raked out, prepared and pointed by hand, finished to suit the masonry. We work on stone surrounds, tenement windows and brick reveals, and people most often call us about tired mastic found when preparing windows for paint and draughts and rain around sash boxes.
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.
Whatever the size of the job, you get the same one-year guarantee.

Skelbo Muir homes and the weather
Skelbo Muir is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That is hard on the mastic around older windows and doors, especially on the side facing the sea. Sash and case windows are common in older Scottish homes, often pointed into the wall with traditional sand mastic.
In and around Skelbo Muir, as anywhere, good sand mastic starts with a clean, dry, properly prepared joint.
Skelbo Muir is about 24 miles north of Nairn, in Highland. Jobs in Skelbo Muir get the same care as everywhere else we work: the old material taken out, joints prepared properly and a 12-month guarantee. Skelbo Muir is one of 253 towns and villages in Highland we cover for sand mastic.

How to look after the new joints
Simple care keeps the joints in good condition. We recommend:
- Get any rot dealt with first
- Don’t run silicone over sand mastic
- Sort the mastic before the decorators arrive
- Find out about consent before window work on a listed home
Leave the new mastic unpainted, which is the traditional advice. If you are redecorating, ask us first.
Sound mastic protects the frame. Once it fails, water can sit against the timber and timber that stays wet can rot.
Honest limits
Before you book, it’s worth knowing the limits:
- Cracked or broken glass
- Rotten sashes, sills or window boxes (a joiner’s job)
- Sashes that need overhauling
If you are not sure, just send an email to info@mrmastic.co.uk and we will give you a straight answer before booking.

Why it’s worth doing now in Skelbo Muir
Before painting the windows, it pays to renew the mastic. Paint over cracked mastic will not stop the gaps, and the new mastic is traditionally left unpainted. Out of town in Scotland, exposed walls take a lot of weather, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
Doing several joints on one visit usually makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. We’ll give you a clear quote for the lot.

What else we do in Skelbo Muir
DIY versus a professional finish
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
Your questions about sand mastic in Skelbo Muir
I let a flat near Golspie station. Can you help?
Yes, landlords and agents are among the people we work for. Just drop us a line at info@mrmastic.co.uk with the address and what needs doing, and we will send you a clear quote.
Do you cover smaller places like Skelbo Muir?
Yes, smaller places are covered as well as towns. We work across all of Scotland. Just mention lanes, gates or anything else about the route when you book.
When will the new mastic be hard?
It takes a while. It skins first and hardens fully later and we’ll give you an idea for your job.
What exactly is sand mastic?
It’s a mix of sand and a linseed-oil-based binder. It’s applied by hand and shaped to suit the surround.
Can I choose the sealant colour?
We help you choose a colour that suits, from white and clear to greys and other shades. The product needed can limit the range.
How long will you be here?
A typical job takes a few hours for a single window, longer for several, including the preparation. We’ll confirm how long when we quote.
Is the work guaranteed?
Every job comes with our one-year guarantee.
Is it OK to seal over old sealant?
No, because it fails. The old sealant always comes out first, so the new joint bonds to clean surfaces.
Signs you need sand mastic in Skelbo Muir
