Sand mastic in Beith
We renew sand mastic around sash windows and doors in stone and brick. Out comes the old, loose mastic, the joint is prepared and new mastic is shaped by hand. If you have window mastic to renew ahead of painting and mastic worn away on windows facing the weather, we can help.
Mastic can only go onto a dry joint, so outside work in Beith depends on the weather, and longer journeys are planned in advance. Let us know about access to every frame, including any upstairs.
A one-year guarantee comes as standard, so you’re covered after we’ve gone.

Your questions about sand mastic in Beith
Do you cover smaller places like Beith?
Yes, Beith is covered. Our work covers the whole of Scotland, and smaller places are part of that. Longer journeys are simply planned in advance.
Do you work for landlords with property near Glengarnock station?
Yes. We work for landlords and agents as well as householders, and several properties can be quoted together. Just send an email to info@mrmastic.co.uk with the address and what needs doing, and we will send you a clear quote.
Is sand mastic better than silicone for my windows?
It depends on the window. On many period windows, sand mastic looks right and suits the building, while modern frames normally get a flexible sealant.
Will you leave a mess?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
Is the work guaranteed?
There’s a 12-month guarantee on every job.
Can sand mastic be painted?
Sand mastic is normally left unpainted, as guidance on traditional windows advises. Talk to us before any painting near it.
Do you work for hotels and businesses?
Yes. Hotels, offices and other businesses use us, and we’re fully insured.
Should I check with the council before work on a listed or conservation-area home?
Your local planning authority is the one to ask. They’ll tell you if consent is needed.
DIY sealant or a professional job?
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
How to look after the new joints
No joint lasts for ever, but care makes a real difference. A few tips:
- Ask the planning authority about consent for listed or conservation-area homes
- Plan mastic work ahead of painting
- Avoid heavy scraping on the mastic joint
- Don’t paint over the new mastic
Do not run silicone over the new mastic. If anything cracks, get it looked at rather than patching it.
Crumbling mastic lets rain into the joint. That water can reach the timber frame and the wall, so renewing it early is worth it.

How the visit works
Good joint work is mostly preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. All told, the work takes anything from a few hours to a full day, depending on how many windows. Outside jobs in Beith need a dry day, because sealant won’t bond to a wet joint, so external jobs may need to move if the day turns wet. Work indoors isn’t affected.

Sand mastic in Beith: local notes
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. 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.
In the older streets around Old Parish Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame. Rented homes near Glengarnock station change hands often, and older sash windows in a rental need their mastic kept sound to keep the weather out.
