Sand mastic for homes and businesses in Yorkhill
We work across Yorkhill renewing sand mastic on sash windows and doors. Every joint is cleaned out and filled by hand, finished to suit the masonry. We’re often asked to deal with cracked mastic round a front door frame and open joints round the window box, across brick reveals, period & listed homes and tenement windows.
Yorkhill is in one of Scotland’s four big cities, where many older buildings are sandstone or granite. Natural stone around older windows needs a sealant that won’t mark or attack it, so acetoxy silicones, which can attack some stone, are best avoided.
Whatever the size of the job, it’s backed by our one-year guarantee.

Frames and glazing around Yorkhill
Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that. Yorkhill is in the west of Scotland, which is wetter than the east, so there’s plenty of rain for the mastic around older windows and doors to keep out.
Rented homes near Partick station change hands often, and any sash windows need sound mastic to keep draughts and rain out. If you look after a building such as Church Street Primary School, larger buildings have plenty of frames, and the mastic around each one ages.

What else we do in Yorkhill
When to call us in Yorkhill
Shallow joints are a common cause. Mastic that’s too thin cracks and drops out so we make sure the new mastic is the right thickness.
Look out for these signs:
- Mastic round period door frames that has failed
- Draughts and rain around sash boxes
- A silicone bead on a sash window that spoils the look
- Mastic worn away on windows facing the weather
Tenement House, about 1.2 miles east, is one of the historic houses in the wider area around Yorkhill, and older homes nearby need a sealant that suits their walls.
What your quote should include
- Which sealant they’ll use, and why
- Whether they seal over old material or remove it
- What the cure time is
- Whether they’re fully insured
Looking after it afterwards
After the cure time, these simple habits help:
- Ask a joiner to look at soft timber first
- Keep modern sealant off the mastic
- Make sure water runs off the sill
- Plan mastic work ahead of painting
Look at the mastic when you look over the windows. Catching cracks early keeps repairs small.
Sound mastic protects the frame. Failed mastic lets water reach the timber and timber that stays wet can rot.
How the job changes by surface
Stone surrounds
Stone openings are rarely perfectly straight, so the gap is not the same all the way round. Sand mastic is shaped by hand to suit.
Timber door frames
Period doors in stone or brick openings are often pointed with sand mastic. We renew it the same way as on windows.
Yorkhill questions
I let a flat near Partick station. Can you help?
Yes, rental work is part of what we do. Just email us at info@mrmastic.co.uk and tell us about the property, and we will give you a clear price.
Can you do sand mastic in Yorkhill?
Yes. We work across all of Scotland, and Yorkhill is part of that. You can drop us a line at info@mrmastic.co.uk and tell us what needs doing.
Can I paint the new mastic?
Traditional guidance is not to paint over sand mastic. Ask us before you decorate around it and we’ll advise.
Can you replace silicone on a period window with sand mastic?
Yes. We remove the silicone and clean the joint, then point it with sand mastic.
Does someone need to be in?
It depends on the job. For work indoors, someone needs to let us in, and for outside work we’ll agree access with you when we book.
Is it messy?
Very little: the area around the joints is protected first, and we tidy up before we go.
Is there any odour?
Sometimes, a little. Any smell clears as the sealant cures, and ventilation helps.
Which is right for my windows, sand mastic or modern sealant?
It depends on the window. Period windows in stone or brick generally suit sand mastic, while modern frames normally get a flexible sealant.
