Sand mastic for homes and businesses in Bunnahabhain
Sand mastic has long been used to fill the joint between timber frames and masonry. It’s a mix of sand and a linseed-oil-based binder and built up by hand. On period homes, it looks right where silicone wouldn’t. We’re often asked to deal with open joints round the window box and draughts and rain around sash boxes, across brick reveals, tenement windows and stone surrounds.
Outdoor sealant needs a dry surface, so window work around Bunnahabhain is planned around the weather, and longer journeys are planned in advance. Let us know about access to every frame, including any upstairs.
Whatever the size of the job, you get the same one-year guarantee in Bunnahabhain and across Argyll and Bute.

Can I do it myself?
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so tell us about it when you ask for a quote.
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.
Sand mastic in Bunnahabhain: local notes
Bunnahabhain is within about 1 mile of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on the mastic around older windows and doors, which can dry out and crack sooner where a building faces the weather. Bunnahabhain is in the west of Scotland, which is wetter than the east, so there’s plenty of rain for the mastic around older windows and doors to keep out.
For jobs in and around Bunnahabhain, choosing the right material for each joint is as important as a tidy finish.

Keeping the joints in good condition
Simple care keeps the joints in good condition. Our advice:
- Clear gutters so water does not pour onto the windows
- Have rotten timber repaired before new mastic goes in
- Look over the window mastic once a year
- Keep modern sealant off the mastic
Check the mastic when you check the paintwork. Small cracks are easier to deal with early.
An open joint round the box lets weather through. The longer it’s left, the more the joint opens as more mastic falls out.
Different surfaces, different methods
Timber door frames
Doors face weather and wear, so their mastic can fail sooner. It’s renewed by hand.
Brick reveals
Brick reveals round timber windows are often pointed with sand mastic. It suits older brickwork.
When it is not the sealant
A few problems are outside what sealant work can do:
