How we handle sand mastic in Crathes
Sand mastic doesn’t last for ever and gaps open up round the frame. We rake it out and renew it so the surround looks right again. If you have modern sealant on a period surround and failed mastic on an exposed elevation, we can put it right, whatever the surface.
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 our one-year guarantee.

Different surfaces, different methods
Stone surrounds
Stone openings are rarely perfectly straight, so the joint varies in width. We shape it by hand to follow the stone.
Sash and case windows
Most of our sand mastic work is on sash windows. We renew the mastic round each box.
When something else is needed
In fairness, there are a few things sealant won’t fix:
- Broken panes
- Sashes that rattle, stick or won’t open
- Damaged stone surrounds
If in doubt, send an email to info@mrmastic.co.uk and we will say what we think before you book.

DIY sealant or a professional job?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
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.
How the visit works
Most of a good job is in the preparation, so that is where we spend the time. Joints are cleaned back and dried before anything new goes in. All told, the work takes anything from a few hours to a full day, depending on how many windows. Outdoor work around Crathes depends on the weather, as sealant needs a dry surface, so an outdoor job can move if the forecast changes. Work indoors isn’t affected.
- Each surround is checked first.
- We rake out the old mastic and clean the joint.
- We fill deep gaps so the new mastic isn’t too thick.
- New sand mastic is applied and shaped by hand.
- The finish is dressed neatly.
Before we arrive
- Where the joints are inside, avoid wetting them before we arrive
- Let us know about parking restrictions
- Tell us about access, such as stairs, a lift or high-level joints

Common problems we fix in Crathes
Over the years, sand mastic weathers. It dries out, cracks and loses its grip from the frame or the masonry.
The most common problems we see are:
- Failed mastic on an exposed elevation
- Draughts and rain around sash boxes
- Old sand mastic that has cracked, crumbled or fallen out
- Modern sealant on a period surround
Whether the job is in Crathes itself or nearby, the right material for each joint matters as much as a neat finish.
