Sand mastic in Widewall: local notes
Widewall is close to 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. On the islands, wind and salt spray are hard on outside sealant.
For jobs in and around Widewall, choosing the right material for each joint is as important as a tidy finish.
Widewall is about 12 miles south of Kirkwall, in the Orkney Islands. We provide sand mastic to homes and businesses in Widewall and nearby, as part of our work across the Orkney Islands. Across the Orkney Islands, we cover 51 places, Widewall among them.

Sand mastic in Widewall, done properly
For a listed home or one in a conservation area, ask your local planning authority if consent is needed before window work. Like-for-like sand mastic is often the preferred finish. If you have draughty sash windows at the surround and cracked mastic round a front door frame, we can help, whatever the surface.
Mastic can only go onto a dry joint, so outside work in Widewall depends on the weather. Tell us about access to all the windows and doors, upstairs included.
Every job comes with our one-year guarantee, wherever you are in the Orkney Islands.

What happens on the day
We work through the job in order: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours for a single window, longer for several and we leave things clean and tidy. For a place like Widewall, longer drives are planned in advance. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- We start by checking each surround and agreeing the joints to renew.
- We rake out the old mastic and clean the joint.
- Deep voids are packed so the mastic is the right thickness.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- The mastic is finished to sit tidily against the stone or brick.
Preparing for the visit
- Tell us if parking is tricky
- Clear items away from the joints we’re working on
- For indoor joints, keep the area dry beforehand if you can

Advice
Leave it or put it right?
Not every filler suits an old window surround. Sand mastic is the like-for-like choice and that can be important for listed homes. Out of town in Scotland, exposed walls take a lot of weather, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.

Signs you need sand mastic in Widewall
Some old mastic was never deep enough. Mastic that is too thin cracks and drops out so we make sure the new mastic is the right thickness.
Any of these means the joints need attention:
- Mastic dropping out of the joint
- Failed mastic on an exposed elevation
- Gaps where the frame meets the masonry
- Draughty sash windows at the surround
Around Widewall, as everywhere, sand mastic is only as good as the preparation behind it.

Your questions about sand mastic in Widewall
Is Widewall in your area for sand mastic?
Yes, Widewall is within the area we cover. We work across all of Scotland. Just drop us a line at info@mrmastic.co.uk with a few details of the job.
Does the coastal weather in Widewall affect outside sealant?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
What does sand mastic cost?
There’s no set price, as it depends on the job: how much there is, what’s there now, how we reach it and what it needs. You’ll get a clear quote before any work starts.
Can you work on commercial sites?
Yes. Commercial and hotel work is a large part of what we do. Working times can be discussed when we quote.
I’m a tenant. Can you help?
We can work for tenants, landlords or agents. Just make sure your landlord agrees.
Will there be a smell?
Some sealants have a smell while they cure, which fades as it sets. Ventilation helps.
Do I need permission for sand mastic on a listed building?
It’s best to ask your local planning authority first. Sand mastic is often favoured as like for like, but they decide.
Are you insured?
Yes. We’re fully insured, with over 20 years’ experience in sealant work.
How the job changes by surface
Stone surrounds
We take care not to mark the stone when the old mastic comes out.
Period and listed homes
Period homes look their best with traditional materials, and sand mastic is one of them.
Looking after it afterwards
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Go gently near the mastic when preparing windows
- Check the mastic when you check the paintwork
- Sort the mastic before the decorators arrive
- Clear gutters so water doesn’t pour onto the windows
Leave the new mastic unpainted, which is the traditional advice. Ask us before any decorating around it.
Crumbling mastic lets rain into the joint. It can soak into the frame and the surrounding masonry, so renewing it early is worth it.
DIY sealant or a professional job?
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
When it is not the sealant
It helps to know what we can’t do:
- Masonry that needs repairing
- Putty and glazing repairs
- Sash cords, weights and draught-proofing of the sashes
Not sure which it is? You can drop us a line at info@mrmastic.co.uk and we will tell you honestly.
