Sand mastic for homes and businesses in Airdriehill
Sand mastic is the traditional way to point the gap between a timber window frame and the stone or brick around it. It’s made from sand and a linseed-oil-based binder, applied by hand. On older homes, it suits the building far better than silicone. We work on stone surrounds, timber door frames and period & listed homes, and common reasons people get in touch are cement or filler used on old window joints that has cracked and wind and rain getting in round a sash window.
Across smaller places in Scotland, homes range from stone and harled cottages to newer houses, many standing in the open. Exposed frames and sills take the full force of wind-driven rain, so the mastic there works hard.
Your job is guaranteed for a year, as with all our work.

- We check the window surrounds and agree which joints need renewing.
- We rake out the old mastic and clean the joint.

Advice
Keeping the joints in good condition
Simple care keeps the joints in good condition. We recommend:
- Have rotten timber repaired before new mastic goes in
- Ask us before painting near the mastic
- Check the mastic when you check the paintwork
- Renew mastic before redecorating the windows
Avoid sealing over the mastic with silicone. If anything cracks, get it looked at rather than patching it.
Fine cracks show the mastic is starting to fail. Renewing it then is simpler than waiting until it falls 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 chosen for how the joint moves and where it is, then guaranteed for a year.
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.
What sand mastic looks like in Airdriehill
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.
In the older streets around Clarkston Church, the joint between an old wall and a newer frame is normally the first place rain gets in. Schools such as Airdrie Academy are buildings too, and the mastic around its windows and doors needs looking after like any other building’s. For landlords with property near Drumgelloch station, cracked sand mastic around sash windows lets in the draughts tenants complain about.

Why act early in Airdriehill
If you are redecorating, renew the mastic first. Painting over failed mastic does not seal it, and the new mastic is traditionally left unpainted. Around Airdriehill, water from a failed joint in an older stone home can soak into timber and plaster.
