About our sand mastic in Pierowall
Burnt sand mastic is a traditional material blends with stone and brick surrounds. It’s a good fit for period properties where a modern sealant bead would stand out. If you have wind and rain getting in round a sash window and a silicone bead on a sash window that spoils the look, we can put it right, on brick reveals, tenement windows and stone surrounds alike.
Across smaller places in Scotland, homes range from stone and harled cottages to newer houses, many standing in the open. Wind-driven rain finds any gap around a frame or sill, so the mastic there works hard.
You get a one-year guarantee, the same in Pierowall as everywhere else we work.

DIY sealant or a professional job?
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
Why it’s worth doing now in Pierowall
New sash windows are a major, costly change, and in listed buildings it may need consent. If the frames are sound, renewing the mastic deals with gaps and draughts at the surround. In a place like Pierowall, small leaks are easy to put off, but water behind a failed seal does the most damage when nobody’s watching.
Leaving a failed joint generally makes the job bigger, not smaller, as water and mould keep getting in. If you are unsure, drop us a line at info@mrmastic.co.uk for an honest opinion and a quote.

Pierowall questions
Does the coastal weather in Pierowall affect outside sealant?
Coastal homes put outside sealant through more weather than inland ones, so preparation and the right sealant matter all the more. Walls facing the sea are normally the first to need attention.
Do you cover Pierowall for sand mastic?
Yes. We work across all of Scotland, and Pierowall is part of that. Just drop us a line at info@mrmastic.co.uk with a few details of the job.
Do you guarantee sand mastic work?
You get our one-year guarantee to all our work.
What sealant do you use?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
Do you remove the old sealant?
Always. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
How do I get a quote for sand mastic in Pierowall?
It depends on the job, so we quote each one individually. For a quick quote, drop us a line at info@mrmastic.co.uk and tell us what needs doing and where.
What is sand mastic?
Sand plus a binder based on linseed oil. It’s applied by hand and shaped to suit the surround.
Is consent needed for window work on a listed home?
Check with your local planning authority. They’ll tell you if consent is needed for work to your windows.
What sand mastic looks like in Pierowall
Pierowall 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. Work on the islands has to be planned around ferry crossings and the weather, so the more notice, the better.
Homes close to Baptist Church include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
Pierowall is about 24 miles north of Kirkwall, in the Orkney Islands.

Signs you need sand mastic in Pierowall
Paint, silicone or cement used over old mastic causes problems. They do not suit the joint, and they usually need raking out.
Keep an eye out for any of the following:
- Mastic that needs renewing before redecorating
- Gaps between timber frames and stone or brick
- Failed mastic on an exposed elevation
- Cement or filler used on old window joints that has cracked
In and around Pierowall, as anywhere, good sand mastic starts with a clean, dry, properly prepared joint.

Surface by surface
Sash and case windows
Most of our sand mastic work is on sash windows. We renew the mastic round each box.
Stone surrounds
We take care not to mark the stone while raking out the old mastic.
Looking after it afterwards
Good habits help new joints last longer. Our tips:
- Clear gutters so water does not pour onto the windows
- Leave the new mastic unpainted
- Have rotten timber repaired before new mastic goes in
- Ask the planning authority about consent for listed or conservation-area homes
When preparing windows for paint, take care around the mastic. Hard scraping can loosen it.
Renewing mastic before redecorating saves doing it twice. Painting over failed mastic hides the problem for a while.

We regularly work with letting and managing agents. Tell us the address, the job and how access works and we’ll quote.
