Sand mastic for sash & case windows in Crown, Highland
Problem with your window and door surrounds in Crown? We remove the old material, prepare the joints and seal them properly.
- Failed mastic on an exposed elevation
- Mastic dropping out of the joint
- Tired mastic found when preparing windows for paint
Keeping the joints in good condition
Good habits help new joints last longer. A few tips:
- Look over the window mastic once a year
- Renew mastic before redecorating the 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 alone while it firms up. It forms a skin fairly soon but needs longer to fully harden.
Once mastic starts to crumble, rain gets in. It can soak into the frame and the surrounding masonry, so renewing it early is worth it.
Sand mastic in Crown
Traditional burnt sand mastic that sits naturally against stone and brick. It’s a good fit for period properties where a modern sealant bead would stand out. If you’re dealing with open joints round the window box and a silicone bead on a sash window that spoils the look, we can put it right.
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, so the mastic there works hard.
A 12-month guarantee comes as standard, so you are not left on your own once the job is done.

What else we do in Crown
Leave it or put it right?
Cement-based fillers and modern sealants don’t always suit a period surround. Sand mastic is the like-for-like choice and that can be important for listed homes. In an older home around Crown, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.
The cost depends on the amount of work, how hard the old material is to remove and how easy the joints are to reach. You’ll have a clear quote before any work starts.

Advice
Signs you need sand mastic in Crown
Decorating can disturb tired mastic. Many people find it crumbling when they prepare the windows, which is a good time to renew it.
Signs it’s time to call us include:
- Gaps where the frame meets the masonry
- Old sand mastic that has cracked, crumbled or fallen out
- Old cement repairs round a window that have failed
- Mastic worn away on windows facing the weather
Schools such as Millburn Academy are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.

Crown homes and the weather
Crown 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. Many older homes in Scotland have sash and case windows, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic.
If you let a flat or house near Inverness station, any sash windows need sound mastic to keep draughts and rain out.
Crown is about 1 mile north-east of Inverness, in Highland. We carry out sand mastic for homes and businesses in Crown and nearby. We cover 253 towns and villages across Highland.
