Sand mastic for homes and businesses in Dreghorn
Sand mastic is the traditional way to point the gap between a timber window frame and the stone or brick around it. It’s a mix of sand and a linseed-oil-based binder, applied by hand. On older homes, it suits the building far better than silicone. Typical jobs include mastic dropping out of the joint and cracked mastic round a front door frame, on sash and case windows, stone surrounds and brick reveals.
Many older Scottish homes still have timber windows set into stone walls. The sealant has to suit the stone, which rules out acetoxy silicones that can mark or attack it.
Big or small, it’s backed by our one-year guarantee in Dreghorn and across North Ayrshire.

Keeping the joints in good condition
Good habits help new joints last longer. A few tips:
- Make sure water runs off the sill
- Have rotten timber repaired before new mastic goes in
- Avoid heavy scraping on the mastic joint
- Leave the new mastic unpainted
Look at the mastic when you look over the windows. Small cracks are easier to deal with early.
Good mastic helps keep the frame dry. Failed mastic lets water reach the timber and timber that stays wet can rot.

The process
We work through the job in order: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours for a single window, longer for several, and the area is left clean. Around Dreghorn, distance and access matter more than parking. Tell us how to find the property and how to reach the work.
- We start by checking each surround and agreeing the joints to renew.
- We rake out the old mastic and clean the joint.
- We pack any deep gaps so the mastic sits at the right depth.
- We mix the sand mastic and apply it by hand, shaping it to the joint.
- We dress the surface so it sits neatly against the masonry.
Getting ready for the visit

Related advice
Should I try it myself first?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.

Dreghorn homes and the weather
Dreghorn is within about 3 miles of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That’s hard on the mastic around older windows and doors, especially on the side facing the sea. The west of Scotland is wetter than the east, so there’s plenty of rain for the mastic around older windows and doors to keep out.
Girgenti House, about 3.6 miles north, is one of the historic houses in the wider area around Dreghorn. For site and facilities teams at buildings such as Greenwood Academy, larger buildings have plenty of frames, and the mastic around each one ages.
