How we handle sand mastic in Canisbay
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. Common call-outs are for tired mastic found when preparing windows for paint and cement or filler used on old window joints that has cracked, on sash and case windows, stone surrounds and brick reveals.
Outdoor sealant needs a dry surface, so window work around Canisbay is planned around the weather, and longer journeys are planned in advance. Tell us about access to all the windows and doors, upstairs included.

Why it’s worth doing now in Canisbay
Not every draught comes from the sashes themselves. Open mastic joints round the box can let air in, and renewing the mastic closes them. In a place like Canisbay, small leaks are easy to put off, but water through a failed joint keeps working away until it’s fixed.
Leaving a failed joint generally makes the job bigger, not smaller. If you are unsure, email us at info@mrmastic.co.uk for an honest opinion and a quote.

Sash and case windows
The box of a sash and case window sits in the stone or brick opening. The gap round it is pointed with sand mastic.
Sand mastic in Canisbay: local notes
Canisbay is within about 1 mile of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on the mastic around older windows and doors, which can dry out and crack sooner where a building faces the weather. Many older homes in Scotland have sash and case windows, often pointed into the wall with traditional sand mastic.
In and around Canisbay, as anywhere, good sand mastic starts with a clean, dry, properly prepared joint. If you live in an older home near Canisbay Parish Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
Canisbay is about 15 miles east of Thurso, in Highland. Homes, rented property, offices and hotels in Canisbay is covered for sand mastic. The work is guaranteed for a year. Canisbay is one of 253 places in Highland we cover.

DIY versus a professional finish
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.

Questions from Canisbay
Does the coastal weather in Canisbay affect outside sealant?
Near the sea, outside joints face more wind, rain and salt than they would inland, so preparation and the right sealant matter all the more. It’s worth checking the walls that face the sea first.
Is Canisbay in your area for sand mastic?
Yes. Our work covers the whole of Scotland, and Canisbay is part of that. You can drop us a line at info@mrmastic.co.uk and tell us what needs doing, and we’ll give you a clear price.
Is sand mastic better than silicone for my windows?
For period timber windows in stone or brick, sand mastic is often the better fit. Modern frames normally suit a flexible sealant, and we’ll explain why.
Is there any odour?
It depends on the product. Some products have a noticeable smell, others very little.
Do you have insurance?
Yes. We are fully insured, and we can confirm the details when we quote.
Do you hold any approvals?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
How long does the job take?
As a guide, most jobs take anything from a few hours to a full day, depending on how many windows. Bigger jobs take longer, and we will say how long yours will take.
Is the work guaranteed?
Every job comes with our one-year guarantee, and we’re fully insured.

Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Go gently near the mastic when preparing windows
- Renew mastic before redecorating the windows
- Find out about consent before window work on a listed home
- Ask us before painting near the mastic
Leave the new mastic unpainted, which is the traditional advice. If you’re redecorating, ask us first.
Sound mastic protects the frame. Failed mastic lets water reach the timber, which can lead to rot.
Landlord and commercial work in Canisbay
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance.
Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.
How the visit works
At the end, we look at the finished work together and explain the cure time. The visit itself normally takes a few hours for a single window, longer for several, depending on the amount of work. In smaller Scottish places, parking is usually less of an issue than access and distance. Tell us how to find the property and how to reach the work, and the visit is planned around that.
- We check the window surrounds and agree which joints need renewing.
- Old, loose mastic is raked out and the joint cleaned.
- Large voids are packed out first, so the mastic isn’t too thick.
- We mix the sand mastic and apply it by hand, shaping it to the joint.
- The mastic is finished to sit tidily against the stone or brick.
Getting ready for the visit
- Mention any tricky access
- Where the joints are inside, avoid wetting them before we arrive
- For business premises, tell us about site rules or sign-in
