Sand mastic in Innis nan Lìon
Our applicators renew the sand mastic around sash and case windows and doors in stone and brick. Out comes the old, loose mastic, the joint is prepared and new mastic is shaped by hand. We work on timber door frames, sash and case windows and tenement windows, and the jobs we see most are patchy fillers round a sash window and crumbling sand mastic round a window.
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.
There’s a 12-month guarantee on every job, large or small.

Why deal with it now?
Replacing sash windows is a big decision for a period home and on a listed home, consent may be needed. If the frames are sound, renewing the mastic deals with gaps and draughts at the surround. In an older home around Innis nan Lìon, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.

How the job changes by surface
Tenement and terrace windows
In shared buildings, the windows may be part of a wider repair so it’s worth checking responsibilities.
Timber door frames
A neat sand mastic joint round a front door suits a period home.
Work for landlords, hotels and businesses
Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. We can quote for more than one property at once.
If you manage several properties in or around Innis nan Lìon, jobs at different addresses can be quoted together. Just tell us the addresses and what each one needs.
DIY versus a professional finish
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
How it works
We bring everything the job needs with us, so you don’t need to buy or prepare anything. Once we’ve agreed what’s being done, the area is protected and the work begins. It normally takes a few hours for a single window, longer for several. Outdoor work around Innis nan Lìon depends on the weather, as sealant needs a dry surface, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- Each surround is checked first.
- We rake out the old mastic and clean the joint.
- Large voids are packed out.
- We point the joint with sand mastic by hand.

What sand mastic looks like in Innis nan Lìon
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.
