How we handle sand mastic in Wallaceton
On many period windows, sand mastic looks right and suits the building. On modern frames we’d normally use a flexible sealant and we’ll explain which is best for yours. We’re often asked to deal with gaps between timber frames and stone or brick and old sand mastic that has cracked, crumbled or fallen out, across period & listed homes, sash and case windows and stone surrounds.
Many older Scottish homes still have timber windows set into stone walls. The sealant has to suit the stone, which rules out acetoxy silicones that can mark or attack it.
All our work is covered by a one-year guarantee.

How we quote for sand mastic
We do not publish a price list, because jobs vary so much. What we look at:
- How many rooms, windows or areas are involved
- The size of the job
- Whether the work is at height
- The old material and how stubborn it is
The cost reflects the work involved, not a rough estimate. That’s why we ask a few questions first.

- Access, such as stairs, a lift or height
- What’s wrong with the joints now
- Pictures of the joints, sent by email

Why it’s worth doing now in Wallaceton
An open joint round the frame lets weather in. Left, water can reach the timber and the wall so renewing it early protects the window. Around Wallaceton, water from a failed joint in an older stone home can soak into timber and plaster.
What it costs depends on how much there is to do, how much old material has to come out and how easy the joints are to reach. You’ll have a clear quote before any work starts.
What you get with us
- Neat joints and a tidy finish
- Any old sealant cut out fully, not covered over
- Anti-fungal sanitary silicone in wet areas
- Approved under the ARBOMaster scheme
What the job involves on each surface
Stone surrounds
Stone surrounds suit sand mastic well. The finish blends with the masonry.
Tenement and terrace windows
Rows of sash windows on tenements and terraces often need renewing together. We can do one window or several.

Can landlords and businesses book you?
Yes. As well as homeowners, we work for landlords, agents, businesses and hotels in Wallaceton.
Can sand mastic be painted?
Sand mastic is normally left unpainted, which is what traditional guidance recommends. Talk to us before any painting near it.
Is it messy?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
How long does sand mastic take to go off?
Not straight away. It skins first and hardens fully later, and we will tell you what to expect.
How the visit works
Every visit runs the same way: we look at the joints together, protect the area around them, carry out the job and tidy away. It usually takes a few hours for a single window, longer for several. Outside jobs in Wallaceton need a dry day, because sealant won’t bond to a wet joint, so an outdoor job can move if the forecast changes. Indoor work goes ahead whatever the weather.
- First we agree which joints need doing.
- We remove the old, loose mastic.
- Deep gaps are packed so the mastic sits at the right depth.
- The sand mastic is mixed and pressed into the joint by hand.
- The surface is finished to suit the stone or brick.
Getting ready for the visit
- For indoor joints, keep the area dry beforehand if you can
- Move anything stored near the joints
- Keep pets and children clear of the area while we work

What sand mastic looks like in Wallaceton
Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that. 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.
For jobs in and around Wallaceton, choosing the right material for each joint is as important as a tidy finish. Around Wallaceton, as everywhere, sand mastic is only as good as the preparation behind it.

Looking after it afterwards
After the cure time, these simple habits help:
- Go gently near the mastic when preparing windows
- Check with your local planning authority if your home is listed
- Avoid patching sand mastic with silicone
- Don’t paint over the new mastic
Leave the new mastic alone while it firms up. It forms a skin fairly soon but needs longer to fully harden.
Small cracks are a sign the mastic is ageing. It’s easier to renew it before it drops out.
