Sand mastic for homes and businesses in Cairnie
We work across Cairnie renewing sand mastic on sash windows and doors. Every joint is cleaned out and filled by hand, finished to suit the masonry. Common call-outs are for patchy fillers round a sash window and open joints round the window box, on brick reveals, tenement windows and sash and case windows.
Mastic can only go onto a dry joint, so outside work in Cairnie depends on the weather, and longer journeys are planned in advance. Let us know about access to every frame, including any upstairs.
We stand behind the work with a 12-month guarantee, so you’re covered after we have gone.

How the job changes by surface
Tenement and terrace windows
Windows above ground floor need the right access. Tell us the height and we will confirm what’s needed.
Stone surrounds
Stone surrounds suit sand mastic well. It finishes to look like part of the surround.
What happens if it’s left?
Before painting the windows, it pays to renew the mastic. Painting over failed mastic does not seal it, and the new mastic is traditionally left unpainted. 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.
The cost reflects the work involved, not guesswork. That is why we ask a few questions first and agree the price before starting.
Why book with us

Your questions about sand mastic in Cairnie
Will you come out to Cairnie?
Yes, Cairnie is covered. We work across all of Scotland, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
I let a flat near Huntly station. Can you help?
Yes. We work for landlords and letting agents as well as householders. You can drop us a line at info@mrmastic.co.uk with the details for a clear quote.
Does someone need to be in?
It depends on the job. Inside work needs someone to give us access, and for outside work we’ll agree access with you when we book.
Are you an approved applicator?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
Can you seal over the old sealant?
No. The old sealant always comes out first, so the new joint bonds to clean surfaces.
Can I paint the new mastic?
The usual advice is to leave sand mastic unpainted. If you’re redecorating the window, ask us first and we will talk you through it.
Can I do it myself?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
Do you take out the old sealant first?
Yes. Sealing over the old bead is the commonest cause of early failure, so we never do it.
What we do, step by step
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours per window, depending on the condition of the joints, and the area is left clean. For a place like Cairnie, longer drives are planned in advance. Mention tracks, gates, ferries or anything else about the route.
- We check each window surround and the condition of the joint.
- We rake out the old mastic and clean the joint.
- Large voids are packed out.
- We point the joint with sand mastic by hand.
- The finish is dressed neatly.
How to prepare
- Mention if the joints have been sealed before
- For indoor joints, keep the area dry beforehand if you can
- Clear items away from the joints we’re working on

Frames and glazing around Cairnie
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. 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.
If you live in an older home near Cairnie Parish Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

How to look after the new joints
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Check the mastic when you check the paintwork
- Ask a joiner to look at soft timber first
- Renew mastic before redecorating the windows
- Keep sills and gutters clear so water drains away
Leave the new mastic unpainted, as traditional guidance advises. If you’re redecorating, ask us first.
An open joint round the box lets weather through. The longer it’s left, the more the joint opens.
What we are called out for in Cairnie
Some old mastic was never deep enough. A thin layer does not hold well, which is why we pack deep voids first and get the depth right.
Signs it’s time to call us include:
- Mastic that needs renewing before redecorating
- Mastic dropping out of the joint
- Modern sealant on a period surround
- Old cement repairs round a window that have failed
If you let a flat or house near Huntly station, any sash windows need sound mastic to keep draughts and rain out.
