Any of these means the joints need attention:
- Modern sealant on a period surround
- Wind and rain getting in round a sash window
- Open joints round the window box
- Mastic round period door frames that has failed

About our sand mastic in Alloway
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 are dealing with silicone on a period window that looks wrong and gaps between timber frames and stone or brick, we can put it right, on stone surrounds, timber door frames and brick reveals alike.
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.
You’re covered for a year from the day we finish. If there’s a problem with it, please send an email to info@mrmastic.co.uk.

Frames and glazing around Alloway
Alloway is within about 2 miles of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That’s hard on the mastic around older windows and doors, especially on the side facing the sea. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that.
Letting a property close to Ayr station? Then any sash windows need sound mastic to keep draughts and rain out. Homes close to Alloway Kirk include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame.

DIY versus a professional finish
Some sealant jobs are within reach of a careful DIYer, such as a straightforward 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 will not bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
How the job changes by surface
Sash and case windows
Sash windows are where we do most sand mastic work. Each joint round the box is raked out and renewed.
Period and listed homes
Materials matter on listed and conservation-area homes. Sand mastic is often the preferred finish.
How to look after the new joints
So the new joints stay in good condition:
- Find out about consent before window work on a listed home
- Clear gutters so water doesn’t pour onto the windows
- Don’t run silicone over sand mastic
- Leave the new mastic unpainted
Keep gutters and sills clear so water runs away from the surround. Constant wetting wears the mastic faster.
Fine cracks show the mastic is starting to fail. Renewing it then is simpler than waiting until it falls out.

Do I need permission for sand mastic on a listed building?

Do you take out the old sealant first?

Do you hold any approvals?
Yes. We are approved under the ARBOMaster scheme, which is run for the Arbo sealant brand.
What do you put in the joint?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference, and we’ll tell you what we are using.
When will the new mastic be hard?
A skin forms quite soon, but full hardening takes longer. We will tell you what to expect for your job.
