What the job involves on each surface
Sash and case windows
Sash windows are where we do most sand mastic work. Each joint round the box is raked out and renewed.
Period and listed homes
Many older homes were built with sand mastic round the windows. On listed buildings, check with your planning authority first.
Sand mastic in Scarwell
Old sand mastic cracks, crumbles and falls out over time and gaps open up round the frame. We rake it out and renew it so the surround looks right again. We are often asked to deal with wind and rain getting in round a sash window and modern sealant on a period surround, on brick reveals, period & listed homes and timber door frames.
In and around a place like Scarwell, homes range from older stone-built cottages to newer houses. Exposed frames and sills take the full force of wind-driven rain.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

Can I do it myself?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
When something else is needed
New sealant cannot fix everything, and we will tell you before we start. Sealant won’t put right:
- Whether work needs listed building consent
- Decayed frames that need repair
- Cracked or broken glass
If in doubt, drop us a line at info@mrmastic.co.uk and we’ll say what we think before booking.

Scarwell questions
Is sand mastic in a coastal place like Scarwell 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. It’s worth checking the walls that face the sea first.
Can you do sand mastic in Scarwell?
Yes. Our work covers the whole of Scotland, and Scarwell is part of that. You can drop us a line at info@mrmastic.co.uk and let us know what needs doing.
How long does sand mastic take?
As a guide, most jobs take a few hours for a single window, longer for several. Larger jobs naturally take longer, and we’ll say how long yours will take.
Which products do you use?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference.
How long does sand mastic take to go off?
It forms a skin fairly soon and it hardens fully over a longer time. Timing depends on the weather and the joint.
Can I paint the new mastic?
It’s traditionally left unpainted, which is what traditional guidance recommends. Talk to us before any painting near it.
Is the work guaranteed?
Our 12-month guarantee applies on every job.
What exactly is sand mastic?
Sand plus a binder based on linseed oil. It’s applied by hand and finished to sit neatly against the masonry.
The process
All our tools and materials come with us in the van. After a quick look at the joints together, we protect the area and start. Most jobs take a few hours for a single window, longer for several. Outside jobs in Scarwell need a dry day, because sealant will not bond to a wet joint, so external jobs may need to move if the day turns wet. Work indoors isn’t affected.
- We look at the surrounds with you and agree the joints to renew.
- Old mastic and any loose material are raked out.
- We pack any deep voids first.
- We apply the mastic by hand and shape it.
- The surface is finished to suit the stone or brick.
Preparing for the visit
- Let us know about earlier repairs to the joints
- Clear items away from the joints we are working on
- Tell us if parking is tricky

Sand mastic in Scarwell: local notes
Scarwell is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That’s hard on the mastic around older windows and doors, especially on the side facing the sea. Island jobs need planning around ferries and the weather, so give us as much notice as you can.
For an older house near a landmark such as Quoyloo Parish Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
Scarwell is about 14 miles north-west of Kirkwall, in the Orkney Islands. Every kind of property in Scarwell is covered for sand mastic, old or new, large or small. Every job comes with our one-year guarantee. Across the Orkney Islands, we cover 51 places, Scarwell among them.
All of KW16 is within our area for sand mastic. Scarwell is on the B9056, which makes it straightforward to reach with everything needed for sand mastic. Nearby, we also carry out sand mastic in Skeabrae (2 miles east), Dounby (3 miles east), Tenston (3 miles south-east), Hourston (4 miles east) and The Barony (4 miles north). Island and remote addresses take a little more planning, so tell us where you are when you ask for a quote.
Near you in Scarwell
A little further out are Skara Brae Visitor Centre (1.6 miles south) and Earl's Palace (4.1 miles north). Green spaces nearby include The Loons and Loch of Banks RSPB nature reserve and Loch of Isbister.
Why act early in Scarwell
Draughts round a sash window are not always the sashes. Gaps between the frame and the wall can be just as bad, and renewing the mastic closes them. Exposed walls in smaller Scottish places take a lot of wind and rain, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
Doing several joints on one visit normally makes better use of the time than several visits. You’ll get one clear quote for the whole job.
