About our sand mastic in Bowmore
Sand mastic suits most period window surrounds. On modern frames we’d normally use a flexible sealant, and we’ll talk through which suits your home. If you are dealing with mastic worn away on windows facing the weather and tired mastic found when preparing windows for paint, we can put it right, on sash and case windows, brick reveals and stone surrounds alike.
Outdoor sealant needs a dry surface, so window work around Bowmore is planned around the weather, and longer journeys are planned in advance. Let us know about access to every frame, including any upstairs.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

Why it’s worth doing now in Bowmore
Not every draught comes from the sashes themselves. Open mastic joints round the box can let air in, and renewing the mastic closes them. Exposed walls in smaller Scottish places take a lot of wind and rain, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

Common questions in Bowmore
Is sand mastic in a coastal place like Bowmore any different?
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.
Will you come out to Bowmore?
Yes, Bowmore is covered. We work across all of Scotland, and smaller places are part of that. Longer journeys are simply planned in advance.
Will you leave a mess?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
Are you fully insured?
Yes. Full insurance covers our work, and we can confirm the details when we quote.
Should I try DIY first?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Are you ARBOMaster approved?
Yes. We hold ARBOMaster approved applicator status.
Which products do you use?
Each joint gets the product that suits it. Movement, water and weather all affect the choice, and we’ll tell you what we are using.
Is it OK to seal over old sealant?
No, because it fails. The old sealant always comes out first, so the new sealant bonds properly.

When something else is needed
In fairness, some problems need a different trade:
- Cracked or broken glass
- Timber that has rotted
- Sashes that need overhauling
Not sure which it is? You can email us at info@mrmastic.co.uk and we’ll tell you honestly.
Surfaces we seal
- Timber door frames
- Tenement windows
- Sash and case windows
- Stone surrounds
- Period & listed homes
- Brick reveals
Aftercare tips
So the new joints stay in good condition:
- Go gently near the mastic when preparing windows
- Sort the mastic before the decorators arrive
- Check with your local planning authority if your home is listed
- Ask a joiner to look at soft timber first
Do not touch or press the mastic while it hardens. It forms a skin fairly soon, but takes longer to harden fully.
Good mastic helps keep the frame dry. Once it fails, water can sit against the timber and timber that stays wet can rot.

What sand mastic looks like in Bowmore
Bowmore is within about 1 mile of 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. The west of Scotland is wetter than the east, which means the mastic around older windows and doors has to cope with a lot of rain.
Around Bowmore, as everywhere, sand mastic is only as good as the preparation behind it. Whether the job is in Bowmore itself or nearby, the right material for each joint matters as much as a neat finish.
Bowmore (Gaelic: Bogh Mòr) is in Argyll and Bute. From the centre of Bowmore to the outskirts, sand mastic is available for homes and businesses alike. Across Argyll and Bute, we cover 118 places, Bowmore among them. You can also see our page for Glasgow, roughly 78 miles from Bowmore.

DIY versus a professional finish

Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
