About our sand mastic in Braco
For a listed home or one in a conservation area, ask your local planning authority whether consent is needed for work to windows. Sand mastic is often favoured as a like-for-like material. If you have mastic dropping out of the joint and mastic worn away on windows facing the weather, we can put it right, whatever the surface.
Older stone-built homes in Scotland often have sash and case or timber windows set in stone. Those suit a traditional sand mastic or a neutral-cure sealant, not an acetoxy silicone that can attack some stone.
Big or small, it’s backed by our one-year guarantee.

Tenement and terrace windows
Rows of sash windows on tenements and terraces often need renewing together. We work on single windows or whole elevations.
Sash and case windows
A sash window’s box frame sits in the masonry opening. The gap round it is pointed with sand mastic.
What we do, step by step
There is not much for you to do on the day. Show us the job and we’ll take it from there. The job generally takes a few hours for a single window, longer for several from start to finish. 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 look at the surrounds with you and agree the joints to renew.
- We remove the old, loose mastic.
- Deep gaps are packed so the mastic sits at the right depth.
- The sand mastic is mixed and pressed into the joint by hand.
- We dress the finish so it sits neatly against the masonry.
Getting ready for the visit
- For business premises, tell us about site rules or sign-in
- Mention any tricky access
- Mention if the joints have been sealed before

What affects the quote in Braco
The quote reflects the job in front of us. We take into account:
- Any mould that needs treating
- The old material and how stubborn it is
- The product the joint needs
- How many areas need sealing
What it costs depends on the size of the job, how much old material has to come out and access to the work. We give a clear quote before any work starts.
Helping us quote
To help us quote quickly, let us know:
- Access, such as stairs, a lift or height
- The rough size of the job

We quote each job on its own, so start by telling us what you need. Just drop us a line at info@mrmastic.co.uk with the details.
When it is not the sealant
In fairness, there are a few things sealant won’t fix:
- Putty and glazing repairs
- Rotten sashes, sills or window boxes (a joiner’s job)
- Whether work needs listed building consent
If in doubt, email us at info@mrmastic.co.uk and we will say what we think.

What sand mastic looks like in Braco
Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that. 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.
Around Braco, as everywhere, sand mastic is only as good as the preparation behind it. For an older house near a landmark such as Braco U. F. Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

FAQs for Braco
Do you cover smaller places like Braco?
Yes, smaller places are covered as well as towns. We work across all of Scotland. Just mention lanes, gates or anything else about the route when you book.
Can you do sand mastic in Braco?
Yes. Our work covers the whole of Scotland, and Braco is part of that. You can email us at info@mrmastic.co.uk and tell us what needs doing.
Can I choose the sealant colour?
Most of the time, yes. We will explain which colours are available.
Can you replace silicone on a period window with sand mastic?
In most cases. We remove the silicone and clean the joint, then point it with sand mastic.
Do you remove the old sealant?
Yes, always, and completely. New silicone does not stick to old silicone, so any old material comes out before anything new goes in.
Is it worth trying 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.
Can you quote for more than one area?
Yes, and it often makes sense. Combining jobs makes good use of the visit.
Is it messy?
Not at all. The area is protected while we work and cleaned up afterwards.
Aftercare tips
No joint lasts for ever, but care makes a real difference. A few tips:
- Check the mastic when you check the paintwork
- Avoid patching sand mastic with silicone
- Leave the new mastic unpainted
- Ask the planning authority about consent for listed or conservation-area homes
Avoid sealing over the mastic with silicone. If anything cracks, get it looked at rather than patching it.
Crumbling mastic lets rain into the joint. It can soak into the frame and the surrounding masonry so early renewal protects both.
Why it’s worth doing now in Braco
Gaps round a sash window let in rain and draughts. Left, water can reach the timber and the wall so renewing it early protects the window. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water behind a failed seal does the most damage when nobody’s watching.
Doing several joints on one visit usually makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. We will give you a clear quote for the lot.
