Sand mastic for homes and businesses in Braidwood
Sand mastic skins over fairly quickly but full hardening takes longer. Traditionally, sand mastic is left unpainted, so ask us before you decorate. We work on sash and case windows, timber door frames and tenement windows, and the jobs we see most are open joints round the window box and modern sealant on a period surround.
Mastic can only go onto a dry joint, so outside work in Braidwood depends on the weather. Tell us about access to all the windows and doors, upstairs included.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we will put it right.

Can I do it myself?
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

Braidwood: your questions answered
I let a flat near Carluke station. Can you help?
Yes, landlords and agents are among the people we work for. Just email us at info@mrmastic.co.uk with the address and what needs doing, and we’ll give you a clear quote.
Do you cover smaller places like Braidwood?
Yes. Braidwood is within the area we cover, which takes in towns, villages and rural addresses. We work across all of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
Do I have to be there?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
Are you insured?
Yes. We are fully insured.
When will the new mastic be hard?
The surface skins quite quickly, then hardens over a longer period. The weather and joint depth both affect it.
Which is right for my windows, sand mastic or modern sealant?
Sand mastic generally suits period timber windows best. On modern frames, we’d normally use a flexible sealant, and we will explain why.
What do you put in the joint?
Each joint gets the product that suits it. Movement, water and weather all affect the choice, and we will tell you what we are using.
Is it possible to take out silicone and use sand mastic instead?
Yes, we do this often. All the old silicone is removed first so the mastic can sit properly.
Why it’s worth doing now in Braidwood
Before painting the windows, it pays to renew the mastic. Painting over failed mastic doesn’t seal it, and the new mastic is traditionally left unpainted. 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.
The cost depends on how much there is to do, how much old material has to come out and access to the work. You will have a clear quote before any work starts, so you know where you stand.
Why choose Mr Mastic in Braidwood
- Sanitary silicone with an anti-fungal additive in wet areas

Sand mastic in Braidwood: local notes
Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of 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.
Managing a site like Carluke High School? Then larger buildings have plenty of frames, and the mastic around each one ages. Rented homes near Carluke station change hands often, and any sash windows need sound mastic to keep draughts and rain out.

Different surfaces, different methods
Brick reveals
Sand mastic is also used where timber frames meet brick. It gives a traditional finish.
Stone surrounds
Old stone surrounds are often uneven, so the joint varies in width. Sand mastic is shaped by hand to suit.
What affects the cost of sand mastic
Every job gets its own quote. This is what makes a difference:
- Whether there’s mould to deal with
- When we can work, for business premises
- How many rooms, windows or areas are involved
- Whether old sealant or filler has to be cut out
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. We take all of that into account in your quote.
Helping us quote
Photos by email are helpful but not essential. Try to tell us:
