Leave it or put it right?
New sash windows are a major, costly change and on a listed home, consent may be needed. Where the frames are in good order, new mastic seals the surround. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water through a failed joint keeps working away until it’s fixed.
Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs, plus any working-time requirements on site. Ask us for a quote and we’ll explain what it covers.

Sand mastic for homes and businesses in Ravenstruther
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. We work on timber door frames, stone surrounds and brick reveals, and people most often call us about draughts and rain around sash boxes and failed mastic on an exposed elevation.
Older stone-built homes in Scotland often have sash and case or timber windows set in stone. Those suit a traditional sand mastic or a neutral-cure sealant, not an acetoxy silicone that can attack some stone.
We stand behind the work with a 12-month guarantee.

Frames and glazing around Ravenstruther
Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of 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.
Schools such as Lanark Grammar School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.

Looking after it afterwards
No joint lasts for ever, but care makes a real difference. A few tips:
- Renew mastic before redecorating the windows
- Clear gutters so water does not pour onto the windows
- Leave the new mastic unpainted
- Avoid patching sand mastic with silicone
Avoid painting over the new mastic, which is the traditional advice. Ask us before any decorating around it.
Crumbling mastic lets rain into the joint. That water can reach the timber frame and the wall, so renewing it early is worth it.

Asking for a quote
A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- The type of property
- Pictures of the joints, sent by email
- How many joints, rooms or windows are involved
- Any previous sealing or DIY work
Need a quote? Please send an email to info@mrmastic.co.uk and tell us about the job. You will know what we plan to do, and what it will cost, before any work begins.
Should I try it myself first?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.

Tenement and terrace windows
Rows of sash windows on tenements and terraces often need renewing together. We work on single windows or whole elevations.
Stone surrounds
Stone surrounds suit sand mastic well. It finishes to look like part of the surround.
Common problems we fix in Ravenstruther
Most of it is simply age. Sand mastic is a maintenance item like any pointing, depending on exposure and upkeep.
Look out for any of the following:
- Old sand mastic that has cracked, crumbled or fallen out
- Patchy fillers round a sash window
- Draughts and rain around sash boxes
- Failed mastic on an exposed elevation
Rented homes near Carstairs station change hands often, and older sash windows in a rental need their mastic kept sound to keep the weather out.
