Sand mastic in Borestone
Our applicators renew the sand mastic around sash and case windows and doors set in stone or brick. The old mastic is raked out, and new mastic is applied and shaped by hand. We are often asked to deal with gaps between timber frames and stone or brick and mastic that needs renewing before redecorating, across period & listed homes, timber door frames and stone surrounds.
Mastic can only go onto a dry joint, so outside work in Borestone depends on the weather. 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.

Why deal with it now?
New sash windows are a major, costly change, and in listed buildings it may need consent. Where the frames are in good order, new mastic seals the surround. 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.
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part, and we’ll explain the quote if you ask.
Why us?
- Tidy, careful work
- More than 20 years in sealant work
- ARBOMaster approved applicator
- A 12-month guarantee on all work

Questions from Borestone
Do you cover smaller places like Borestone?
Yes, Borestone is covered. Our work covers the whole of Scotland, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Is Borestone in your area for sand mastic?
Yes. We work across all of Scotland, and Borestone is part of that. You can drop us a line at info@mrmastic.co.uk and let us know what needs doing, and we’ll send you a clear quote.
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. We use products from Arbo and Everbuild.
What do you need from me for a quote?
Where the job is, what the problem is and roughly how big it is. Photos by email help too.
What is sand mastic?
It’s a mix of sand and a linseed-oil-based binder. It’s built up in the joint by hand and finished to sit neatly against the masonry.
Will the old sealant be removed?
Always. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Can I do it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Is sand mastic better than silicone for my windows?
That depends on your windows. On many period windows, sand mastic looks right and suits the building, while modern frames normally get a flexible sealant.
What affects the quote in Borestone
For a quick quote, just ask. The main things that affect it are:
- Any working-time requirements on site
- The number and length of the joints
- Whether there’s mould to deal with
- The type of sealant required
Leaving a failed joint usually makes the job bigger, not smaller, because water and mould keep working on it. If you are unsure, drop us a line at info@mrmastic.co.uk for an honest opinion and a quote.
Asking for a quote
What to tell us when you ask for a quote:
- Where the property is
- How we’d reach the joints
- Any previous sealing or DIY work
- If it’s domestic, commercial or a hotel
We quote each job on its own. Just drop us a line at info@mrmastic.co.uk with the details and send pictures if you have them.

Sand mastic in Borestone: local notes
Sash and case windows are common in older Scottish homes, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that.
If you let a flat or house near Stirling station, any sash windows need sound mastic to keep draughts and rain out.

DIY sealant or a professional job?
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.
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
Looking after it afterwards
After the cure time, these simple habits help:
- Look over the window mastic once a year
- Ask the planning authority about consent for listed or conservation-area homes
- Get any rot dealt with first
- Take care around the mastic when scraping paint
Look at the mastic when you look over the windows. Small cracks are easier to deal with early.
Sound mastic protects the frame. Once it fails, water can sit against the timber, which can lead to rot.
The process
We bring everything the job needs with us, so there’s nothing for you to buy. Once we’ve agreed what’s being done, we protect the area and start. It normally takes a few hours per window, depending on the condition of the joints. In smaller Scottish places, parking is usually less of an issue than access and distance. Let us know how to find you and how to reach the joints.
- We check each window surround and the condition of the joint.
- The joint is raked out and cleaned.
- Large voids are packed out.
- We point the joint with sand mastic by hand.
- The finish is dressed neatly.
Preparing for the visit
- Let us know about earlier repairs to the joints
- Where the joints are inside, avoid wetting them before we arrive
- Plan for the work area to be out of bounds to pets and children
