Sand mastic for sash & case windows in Stenness, Orkney Islands
Problem with your window and door surrounds in Stenness? We remove the old material, prepare the joints and seal them properly, with a 12-month guarantee.
- Gaps where the frame meets the masonry
- Draughty sash windows at the surround
- Crumbling sand mastic round a window
What happens on the day
We work through the job in order: protect, prepare, seal, tidy. For most jobs that takes a few hours for a single window, longer for several, and the area is left clean. Outdoor work around Stenness depends on the weather, as sealant needs a dry surface, so external jobs may need to move if the day turns wet. Work indoors is not affected.
- We check each window surround and the condition of the joint.
- We rake out the old mastic and clean the joint.
- We fill deep gaps so the new mastic is not too thick.
- We point the joint with sand mastic by hand.
- The finish is dressed neatly.
Before we arrive
- Keep children and pets away from the work area
- Tell us about access, such as stairs, a lift or high-level joints
- Mention any sign-in or site rules at work premises

How we handle sand mastic in Stenness
Fresh sand mastic forms a skin quite soon, but it takes longer to harden fully. Traditionally, sand mastic is left unpainted and we will advise if you are redecorating. We work on period & listed homes, stone surrounds and brick reveals, and the jobs we see most are silicone on a period window that looks wrong and mastic worn away on windows facing the weather.
Outdoor sealant needs a dry surface, so window work around Stenness is planned around the weather, and longer journeys are planned in advance. Tell us about access to all the windows and doors, upstairs included.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

DIY versus a professional finish
If you’re set on DIY, put the effort into 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.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
When something else is needed
Before booking, it’s worth knowing the limits too:
- Timber that has rotted
- Decisions on consent for listed homes
- Crumbling stone or brickwork round the window
Not sure which it is? You can drop us a line at info@mrmastic.co.uk and we’ll tell you honestly before you book.
Surfaces we seal

What sand mastic looks like in Stenness
Stenness is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That’s hard on the mastic around older windows and doors, especially on the side facing the sea. Work on the islands has to be planned around ferry crossings and the weather, so the more notice, the better.
If you live in an older home near Stenness Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
Stenness is about 9 miles west of Kirkwall, in the Orkney Islands. From the centre of Stenness to the outskirts, we cover sand mastic for every kind of property, from flats and houses to offices and hotels. 51 places in the Orkney Islands are on our list.

Why act early in Stenness
Draughts round a sash window are not always the sashes. Open mastic joints round the box can let air in and new mastic seals them. In a place like Stenness, small leaks are easy to put off, but water through a failed joint keeps working away until it’s fixed.
Combining jobs into one visit is normally more efficient than separate visits, so tell us about everything that needs sealing. We will send you a clear quote for the lot.

What affects the cost of sand mastic
You’ll get a clear quote before we start. It’s based on:
- Any working-time requirements on site
- The type of sealant required
- Mould in or behind the old joints
- The number and length of the joints
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you’re not sure whether it needs doing, email us at info@mrmastic.co.uk and we’ll give you an honest view and a quote.
What we need to know
Before you ask for a quote, have a think about:
- The rough size of the job
- What the problem is, such as mould, gaps, leaks or cracking
- How we’d reach the joints
- Whether it’s a home or a business
Call for a quick quote, or email us if that’s easier. Tell us about the joints that need doing and we’ll talk you through the work and send you a clear quote.
What we are called out for in Stenness
Most of it is simply age. Even well-laid mastic needs renewing in time and how long it lasts depends on the weather it faces.
If you can see any of these, it’s time to have the joints looked at:
- Old cement repairs round a window that have failed
- A silicone bead on a sash window that spoils the look
- Mastic that needs renewing before redecorating
- Gaps where the frame meets the masonry
Around Stenness, as everywhere, sand mastic is only as good as the preparation behind it.

Common questions in Stenness
Will you come out to Stenness?
Yes, Stenness is covered. We work across all of Scotland, islands included, and smaller places are part of that. Longer journeys are simply planned in advance.
Does living near the coast affect sand mastic in Stenness?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. The right product, a clean joint and the right depth all help it cope.
How long does the job take?
It depends on the size of the job, but as a guide it takes a few hours for a single window, longer for several. We will give you a better idea when we quote.
Do I have to be there?
That depends on where the joints are. For work indoors, someone needs to let us in.
What do you put in the joint?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
Can you work on commercial sites?
Yes. We can plan bigger jobs in stages.
Should I try DIY first?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. If it doesn’t work out, we can redo it.
Is it possible to take out silicone and use sand mastic instead?
Often, yes. Once the silicone is out and the joint prepared, sand mastic is applied by hand.
Landlord and commercial work in Stenness
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance.
We also work for property managers and facilities teams. We can quote a run of properties together, and we’re fully insured.
