Sand mastic for homes and businesses in Elderslie
Our applicators renew the sand mastic around sash and case windows and doors in stone and brick. The old mastic is raked out, and new mastic is applied and shaped by hand. If you are dealing with window mastic to renew ahead of painting and mastic dropping out of the joint, we can help, whatever the surface.
Outdoor sealant needs a dry surface, so window work around Elderslie is planned around the weather. Let us know about access to every frame, including any upstairs.

Why deal with it now?
Before painting the windows, it pays to renew the mastic. Paint over cracked mastic won’t stop the gaps, and the new mastic is traditionally left unpainted. Exposed walls in smaller Scottish places take a lot of wind and rain, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
We don’t show prices on the website, because each job is priced on what it involves. Call for a quick quote and we’ll talk you through it.

What else we do in Elderslie
Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. A few tips:
- Look over the window mastic once a year
- Go gently near the mastic when preparing windows
- Have rotten timber repaired before new mastic goes in
- Ask the planning authority about consent for listed or conservation-area homes
Leave the new mastic unpainted, as traditional guidance advises. Ask us before any decorating around it.
Sound mastic protects the frame. Failed mastic lets water reach the timber, which can lead to rot.
Windows and doors in Elderslie
Elderslie 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. Sash and case windows are common in older Scottish homes, often pointed into the wall with traditional sand mastic.
For an older house near a landmark such as East Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame. Rented homes near Johnstone station change hands often, and older sash windows in a rental need their mastic kept sound to keep the weather out.
