Sand mastic for homes and businesses in Mossbank
Burnt sand mastic is a traditional material that sits naturally against stone and brick. It’s a good fit for period properties where a modern sealant bead would stand out. We work on period & listed homes, stone surrounds and tenement windows, and people most often call us about gaps between timber frames and stone or brick and draughty sash windows at the surround.
Outdoor sealant needs a dry surface, so window work around Mossbank is planned around the weather. Tell us about access to all the windows and doors, upstairs included.
A 12-month guarantee comes as standard, so you are not left on your own once the job is done.

Windows and doors in Mossbank
Mossbank 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. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that.
In and around Mossbank, as anywhere, good sand mastic starts with a clean, dry, properly prepared joint.
Mossbank is in the Shetland Islands. Anywhere in ZE2, we cover sand mastic for homes and businesses. Mossbank is one of 63 towns and villages in the Shetland Islands where we work.
Work in ZE2 works the same way as everywhere else we cover. Sand mastic is available to properties on Smuggabank, Rayburn Road and Burraness and the roads around them. We also cover the places around Mossbank: Firth (1 mile south-west), Scatsta (4 miles south-west), Burravoe (5 miles north-east), Ollaberry (6 miles north-west) and Vidlin (6 miles south).

Keeping the joints in good condition
How long the joints last depends on use and care. Here’s what we suggest:
- Do not run silicone over sand mastic
- Ask a joiner to look at soft timber first
- Take care around the mastic when scraping paint
- Leave the new mastic unpainted
Check the mastic when you check the paintwork. Small cracks are easier to deal with early.
Good mastic helps keep the frame dry. Once it fails, water can sit against the timber and timber that stays wet can rot.
What affects the quote in Mossbank
The quote reflects the job in front of us. We look at:
- The product the joint needs
- How easy the joints are to reach
- When we can work, for business premises
- Any mould that needs treating
The cost reflects the work involved, not a rough estimate. That is why we ask a few questions first.

The process
At the end, we look at the finished work together and explain the cure time. The work normally takes a few hours per window, depending on the condition of the joints, depending on the amount of work. Around Mossbank, distance and access matter more than parking. Let us know how to find you and how to reach the joints.
- We check the window surrounds and agree which joints need renewing.
- We rake out the old mastic and clean the joint.
- We pack any deep gaps so the mastic sits at the right depth.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- The finish is dressed so it sits neatly against the stone or brick.
Preparing for the visit

Questions from Mossbank
Does the coastal weather in Mossbank affect outside sealant?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
Can you do sand mastic in Mossbank?
Yes, Mossbank is within the area we cover. Our work covers the whole of Scotland. You can email us at info@mrmastic.co.uk and let us know what needs doing.
Can sand mastic be painted?
It’s traditionally left unpainted, which is what traditional guidance recommends. Ask us before decorating.
Will there be a smell?
There can be a smell while the sealant cures, which fades as it sets. Opening a window helps.
Is it possible to take out silicone and use sand mastic instead?
Yes, it’s a common request. The old silicone has to come out completely so the mastic beds in well.
Are you ARBOMaster approved?
Yes. Mr Mastic is an ARBOMaster approved applicator.
Is the work guaranteed?
Our 12-month guarantee applies to all our work.
What information do you need?
Just the basics: the address or postcode, what’s wrong and any access issues. After that, simply send an email to info@mrmastic.co.uk.
How the job changes by surface
Tenement and terrace windows
In shared buildings, the windows may be part of a wider repair, so check who is responsible first.
Stone surrounds
We take care not to mark the stone when the old mastic comes out.
Common problems we fix in Mossbank
Previous repairs in cement or silicone often trap water or crack away. They don’t suit the joint and we normally remove them.
Common reasons people contact us are:
- Silicone on a period window that looks wrong
- Tired mastic found when preparing windows for paint
- Mastic round period door frames that has failed
- Gaps between timber frames and stone or brick
Whether the job is in Mossbank itself or nearby, the right material for each joint matters as much as a neat finish.
