How we handle sand mastic in Caddonfoot
Our applicators renew the sand mastic around sash and case windows and doors set in stone or brick. The old mastic is raked out, and new mastic is applied and shaped by hand. We work on stone surrounds, period & listed homes and sash and case windows, and the jobs we see most are window mastic to renew ahead of painting and cement or filler used on old window joints that has cracked.
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.
All of our work is guaranteed for twelve months.

Frames and glazing around Caddonfoot
Sash and case windows are common in older Scottish homes, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that.
Peel House, about 1 mile west, is one of the historic houses in the wider area around Caddonfoot, and older homes nearby need a sealant that suits their walls.

What we’re called out for in Caddonfoot
Timber swells and shrinks with the weather. That movement opens up the mastic joint little by little.
Any of these means the joints need attention:
- Mastic worn away on windows facing the weather
- Crumbling sand mastic round a window
- Silicone on a period window that looks wrong
- Gaps where the frame meets the masonry
Rented homes near Galashiels station change hands often, and any sash windows need sound mastic to keep draughts and rain out.

Leave it or put it right?
Silicone might seem the quicker option, but on period stone or brick it often looks out of place. Sand mastic is the traditional material and blends with the stone or brick. In a place like Caddonfoot, small leaks are easy to put off, but water through a failed joint keeps working away until it’s fixed.
What it costs depends on the size of the job, how hard the old material is to remove and access to the work. You’ll have a clear quote before any work starts.

Looking after it afterwards
So the new joints stay in good condition:
- Ask a joiner to look at soft timber first
- Inspect the joints round the windows every year or so
- Renew mastic before redecorating the windows
- Take care around the mastic when scraping paint
When preparing windows for paint, take care around the mastic. Hard scraping can loosen it.
Gaps round a sash box let in draughts and rain. Left, the gap tends to get bigger as more mastic falls out.
Different surfaces, different methods
Period and listed homes
Materials matter on listed and conservation-area homes. Like-for-like sand mastic is normally favoured.
