Traditional burnt sand mastic around sash and case windows and doors in stone and brick for Bunessan, backed by a one-year guarantee. Call for a quick quote.
- Wind and rain getting in round a sash window
- Gaps between timber frames and stone or brick
- Silicone on a period window that looks wrong
Why it’s worth doing now in Bunessan
Not every draught comes from the sashes themselves. 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 once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
Doing several joints on one visit is generally more efficient than separate visits, so it’s worth mentioning everything you’d like done. You’ll get one clear quote for the whole job.

About our sand mastic in Bunessan
For a listed home or one in a conservation area, ask your local planning authority if consent is needed before window work. Like-for-like sand mastic is often the preferred finish. Typical jobs include weathered mastic on the most exposed windows and gaps round a timber door in stone or brick, on timber door frames, brick reveals and period & listed homes.
In and around a place like Bunessan, homes range from older stone-built cottages to newer houses. Exposed frames and sills take the full force of wind-driven rain.
We stand behind the work with a one-year guarantee, so you are not left on your own once the job is done.

How it works
You don’t need to clear the whole room or building, just the space around the work. Everything nearby is protected, and the work takes anything from a few hours to a full day, depending on how many windows in most cases. Outdoor work around Bunessan depends on the weather, as sealant needs a dry surface, so an outdoor job can move if the forecast changes. Work indoors is not affected.
- First we agree which joints need doing.
- We remove the old, loose mastic.
- Deep gaps are packed so the mastic sits at the right depth.
- We apply the mastic by hand and shape it.
- The surface is finished to suit the stone or brick.
Before we arrive
- Keep children and pets away from the work area
- Mention any parking rules near the property
- Move anything stored near the joints

Questions from Bunessan
Does the coastal weather in Bunessan 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.
Can you do sand mastic in Bunessan?
Yes. We work across all of Scotland, and Bunessan is part of that. You can drop us a line at info@mrmastic.co.uk and let us know what needs doing.
Can I choose the sealant colour?
Usually, yes. Sealants come in white, clear, grey and other colours, and we agree the colour with you before work begins.
Can I paint the new mastic?
The usual advice is to leave sand mastic unpainted. Ask us before you decorate around it and we will talk you through it.
Should I try DIY first?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. If it does not work out, we can redo it.
Will the old sealant be removed?
Yes. All of the old material is cut out and the joint cleaned before applying anything new.
Is it possible to take out silicone and use sand mastic instead?
Often, yes. With the silicone removed and the joint cleaned we point it with sand mastic.
Are you fully insured?
Yes, we are fully insured.
Sand mastic in Bunessan: local notes
Bunessan 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 is hard on the mastic around older windows and doors, especially on the side facing the sea. Many older homes in Scotland have sash and case windows, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic.
Homes close to Kilvickeon Church include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame.

What affects the cost of sand mastic
The price is agreed before any work begins. It takes into account:
- When we can work, for business premises
- How easy the joints are to reach
- The size of the job
- Any mould that needs treating
The cost reflects the work involved, not guesswork. That’s why we ask a few questions first.

Different surfaces, different methods
Period and listed homes
Sand mastic is the like-for-like choice for many period homes. If your home is listed, ask your local planning authority about consent.
Sash and case windows
The box of a sash and case window sits in the stone or brick opening. Sand mastic seals the joint round it.
Honest limits
In fairness, some problems need a different trade:
- Crumbling stone or brickwork round the window
- Decisions on consent for listed homes
- Sashes that need overhauling
If you are not sure, just email us at info@mrmastic.co.uk and we’ll give you a straight answer.

What we’re called out for in Bunessan
Some old mastic was never deep enough. Mastic that’s too thin cracks and drops out, which is why we pack deep voids first and get the depth right.
Keep an eye out for any of the following:
- Draughts and rain around sash boxes
- Old sand mastic that has cracked, crumbled or fallen out
- Modern sealant on a period surround
- Window mastic to renew ahead of painting
Around Bunessan, as everywhere, sand mastic is only as good as the preparation behind it.
