How we handle sand mastic in Skirling
We renew sand mastic around sash windows and doors set in stone or brick. The old mastic is raked out, the joint is prepared and new mastic is shaped by hand. We work on period & listed homes, tenement windows and stone surrounds, and people most often call us about mastic dropping out of the joint and tired mastic found when preparing windows for paint.
Outdoor sealant needs a dry surface, so window work around Skirling is planned around the weather. Let us know about access to every frame, including any upstairs.

What sand mastic looks like in Skirling
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.
For jobs in and around Skirling, choosing the right material for each joint is as important as a tidy finish. Around Skirling, as everywhere, sand mastic is only as good as the preparation behind it.

Related advice
Can I do it myself?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
Landlord and commercial work in Skirling
We work for landlords and letting agents as well as householders. Sealant work between tenants keeps a property looking cared for.
Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.
Why act early in Skirling
Gaps round a sash window let in rain and draughts. Water can get to the frame and the masonry so renewing it early protects the window. In an older home around Skirling, damp from a failed joint can get into timber and plaster.
The cost depends on the amount of work, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before any work starts, so you know where you stand.

Aftercare tips
Good habits help new joints last longer. A few tips:
- Ask us before painting near the mastic
- Make sure water runs off the sill
- Avoid heavy scraping on the mastic joint
- Get any rot dealt with first
Do not run silicone over the new mastic. If you see a crack, ask us to take a look rather than patching it.
It’s best to renew mastic before painting the windows. Paint over cracked mastic only covers it up.
