Frames and glazing around Muirend
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. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that.
If you let a flat or house near Muirend station, any sash windows need sound mastic to keep draughts and rain out. Managing a site like Hillpark Secondary School? Then its window and door frames need their mastic kept sound, just like a home’s. For an older house near a landmark such as Merrylea Parish Church, the joint between an old wall and a newer frame is generally the first place rain gets in.

Sand mastic in Muirend

We work on sash and case windows, stone surrounds and tenement windows, and common reasons people get in touch are mastic that needs renewing before redecorating and crumbling sand mastic round a window.
In a Scottish city, many flats have windows two, three or four floors up, where failing mastic is easy to miss. Access is the first thing to plan for a job in Muirend, and in a tenement the outside of the building may be a shared repair.

How the job changes by surface
Brick reveals
An open joint at a brick reveal lets weather in. New mastic seals the gap.
Timber door frames
Period doors in stone or brick openings are often pointed with sand mastic. The method is the same as for windows.
Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. A few tips:
- Look over the window mastic once a year
- Get any rot dealt with first
- Sort the mastic before the decorators arrive
- Avoid heavy scraping on the mastic joint
Make sure water drains away from the window surround. Water sitting against the mastic shortens its life.
Fine cracks show the mastic is starting to fail. It’s easier to renew it before it drops out.

Advice
Your questions about sand mastic in Muirend
How do repairs to the shared parts of a tenement in Muirend get organised?
Most tenements arrange shared repairs through the owners or a property factor. The Tenements (Scotland) Act 2004 sets the rules for common parts if the deeds don’t.
I let a flat near Muirend 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 quote.
Which is right for my windows, sand mastic or modern sealant?
That depends on your windows. Period windows in stone or brick generally suit sand mastic, while modern frames normally get a flexible sealant.
Do you take out the old sealant first?
Yes. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
What guarantee comes with the work?
Our 12-month guarantee covers every job.
Can sand mastic be painted?
The usual advice is to leave sand mastic unpainted. Ask us before you decorate around it and we will advise.
What’s sand mastic made of?
Sand mastic is a traditional material for pointing round windows and doors. It combines sand with a linseed-oil-based binder.
Can new sealant go over the old?
No, and we never do. It can look neat for a few weeks, but the new layer lifts away from the old one. The old sealant has to come out completely.
Work for landlords, hotels and businesses
We regularly work with letting and managing agents. Tell us the address, the job and how access works.
Housing providers, facilities teams and property managers book us too in Muirend and across Glasgow. We can quote a run of properties together, and we’re fully insured.
Should I try it myself first?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
