Cairston Sand Mastic
Traditional burnt sand mastic around sash and case windows and doors in stone and brick for homeowners, landlords and businesses in Cairston. ARBOMaster approved applicators, fully insured, with a one-year guarantee.
- Modern sealant on a period surround
- Open joints round the window box
- Mastic worn away on windows facing the weather
DIY versus a professional finish
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
How we handle sand mastic in Cairston
On many period windows, sand mastic looks right and suits the building. Newer frames normally get a flexible sealant instead and we will explain which is best for yours. We work on stone surrounds, timber door frames and tenement windows, and the jobs we see most are mastic round period door frames that has failed and draughty sash windows at the surround.
Mastic can only go onto a dry joint, so outside work in Cairston depends on the weather, and longer journeys are planned in advance. Tell us about access to all the windows and doors, upstairs included.
Big or small, it’s backed by our 12-month guarantee.

Cairston questions
Can you do sand mastic in Cairston?
Yes, Cairston is within the area we cover. We work across all of Scotland. You can email us at info@mrmastic.co.uk and tell us what needs doing.
Is sand mastic in a coastal place like Cairston any different?
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. Walls facing the sea are usually the first to need attention.
How long does sand mastic take?
Typically it takes a few hours for a single window, longer for several. Larger jobs naturally take longer, and we will say how long yours will take.
Is sand mastic better than silicone for my windows?
Sand mastic usually suits period timber windows best. On modern frames, we’d normally use a flexible sealant, and we’ll explain why.
Should I try DIY first?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
When will the new mastic be hard?
It forms a skin fairly soon and it hardens fully over a longer time. Timing depends on the weather and the joint.
What information do you need?
The location, the problem and the rough size of the job. Photos by email help too.
I’m a tenant. Can you help?
Yes. Check with your landlord; we can send the quote to them too.
What happens if it’s left?
Not every draught comes from the sashes themselves. Gaps between the frame and the wall can be just as bad and new mastic seals them. In a place like Cairston, small leaks are easy to put off, but water behind a failed seal does the most damage when nobody’s watching.
We do not show prices on the website, because the cost depends so much on the job itself. Call for a quick quote.

When to call us in Cairston
Rain on the window surround works into any crack and loosens it further. Exposed elevations generally fail first.
Look out for these signs:
- Modern sealant on a period surround
- Cement or filler used on old window joints that has cracked
- Window mastic to renew ahead of painting
- Mastic worn away on windows facing the weather
If you look after a building such as stromness primary school, its window and door frames need their mastic kept sound, just like a home’s.

Keeping the joints in good condition
To keep the joints looking good and working properly:
- Avoid heavy scraping on the mastic joint
- Get any rot dealt with first
- Keep modern sealant off the mastic
- Renew mastic before redecorating the windows
When preparing windows for paint, take care around the mastic. Hard scraping can loosen it.
An open joint round the box lets weather through. Left, the gap tends to get bigger as more mastic falls out.
Frames and glazing around Cairston
Cairston is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on the mastic around older windows and doors, which can dry out and crack sooner where a building faces the weather. On the islands, wind and salt spray are hard on outside sealant.
Around Cairston, as everywhere, sand mastic is only as good as the preparation behind it.

What we do, step by step
You don’t need to clear the whole room or building before we come, only the area right around the joints. We protect the rest, and the work takes a few hours for a single window, longer for several for a typical job. In smaller Scottish places, parking is generally 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.
- Old mastic and any loose material are raked out.
- 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
- Tell us if parking is tricky
- Mention if the joints have been sealed before
- On commercial sites, let us know about site rules
