How we handle sand mastic in Newstead
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 older homes, it suits the building far better than silicone. We are often asked to deal with draughts and rain around sash boxes and mastic dropping out of the joint, on sash and case windows, timber door frames and period & listed homes.
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.
A 12-month guarantee comes as standard, so you are not left on your own once the job is done.

Aftercare tips
Aftercare is simple, and it makes a real difference:
- Keep sills and gutters clear so water drains away
- Ask us before painting near the mastic
- Check the mastic when you check the paintwork
- Renew mastic before redecorating the windows
Do not run silicone over the new mastic. If you see a crack, ask us to take a look rather than patching it.
Good mastic helps keep the frame dry. Failed mastic lets water reach the timber, which can lead to rot.

How it works
Good joint work is mostly preparation, and we don’t rush it. Joints are cleaned back and dried before anything new goes in. All told, the work takes anything from a few hours to a full day, depending on how many windows. Outdoor work around Newstead depends on the weather, as sealant needs a dry surface, so an outdoor job can move if the forecast changes. Work indoors isn’t affected.
- First, we look at the surrounds with you and agree what needs doing.
- The loose and crumbling mastic is raked out and the joint cleaned.
- Large voids are packed out first, so the mastic is not too thick.
- The mastic is mixed, pressed into the joint by hand and shaped.
- We dress the surface so it sits neatly against the masonry.
Preparing for the visit
- For indoor joints, keep the area dry beforehand if you can
- Keep children and pets away from the work area
- On commercial sites, let us know about site rules

Advice
Sand mastic in Newstead: local notes
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. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and sound outside sealant is part of that.
Rented homes near Tweedbank station change hands often, and cracked sand mastic around sash windows lets in the draughts tenants complain about.

Leave it or put it right?
Draughts round a sash window aren’t always the sashes. Gaps between the frame and the wall can be just as bad, and renewing the mastic closes them. Out of town in Scotland, exposed walls take a lot of weather, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
The cost depends on the amount of work, how hard the old material is to remove and access to the work. You will have a clear quote before any work starts, so you know where you stand.
