- Patchy fillers round a sash window

How to look after the new joints
A little care helps the new joints last. Our advice:
- Ask a joiner to look at soft timber first
- Make sure water runs off the sill
- Check the mastic when you check the paintwork
- Plan mastic work ahead of painting
When preparing windows for paint, take care around the mastic. Hard scraping can loosen it.
Small cracks are a sign the mastic is ageing. Renewing it then is simpler than waiting until it falls out.
Sand mastic in Cardonald, done properly

Cardonald: your questions answered
Can you do sand mastic in Cardonald?
Yes. Our work covers the whole of Scotland, and Cardonald is part of that. Just drop us a line at info@mrmastic.co.uk with a few details of the job.
How is work on the outside of a tenement in Cardonald usually arranged?
The owners of the flats normally agree repairs to shared parts like the roof and outside walls, and many buildings have a factor to arrange it. The Tenements (Scotland) Act 2004 sets out how that works where the title deeds don’t. Your title deeds will say who owns the windows.
What sealant do you use?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
Can old silicone round a sash window be swapped for sand mastic?
Yes, it’s a common request. All the old silicone is removed first so the mastic can sit properly.
Where is Mr Mastic based?
We’re based in Crawley, and we work across South East England, London and Scotland.
Should I try DIY first?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
How do I get a quote for sand mastic in Cardonald?
It depends on the job, so we quote each one individually. For a quick quote, send an email to info@mrmastic.co.uk and tell us what needs doing and where.
Is it possible to paint over sand 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.

What we’re called out for in Cardonald
Age is the main cause. Sand mastic is a maintenance item like any pointing, depending on exposure and upkeep.
It’s worth asking for a quote if you see:
- Modern sealant on a period surround
- Cement or filler used on old window joints that has cracked
- Tired mastic found when preparing windows for paint
- Gaps where the frame meets the masonry
For landlords with property near Hillington East station, cracked sand mastic around sash windows lets in the draughts tenants complain about.
Questions to ask before you book
- Whether they’re fully insured
- The length of the guarantee
- Who does the work, and how experienced they are
- Whether you can choose the colour
Leave it or put it right?
Not every filler suits an old window surround. Sand mastic is the like-for-like choice, which can matter on listed and conservation-area homes. For landlords in Cardonald, damp and leaks can be a Repairing Standard issue, so failed sealant is best replaced before it becomes a complaint.
Combining jobs into one visit is normally more efficient than separate visits. We’ll send you a clear quote for the lot.

The process
When we get to you, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. After that, the work takes a few hours for a single window, longer for several. Parking in city streets around Cardonald can be tight or controlled, so it helps to know about permits or nearby bays. For flats, mention the door entry system and any shared-stair arrangements.
- Each surround is checked first.
- The joint is raked out and cleaned.
- We fill deep gaps so the new mastic is not too thick.
- New sand mastic is applied and shaped by hand.
- The finish is dressed neatly.

Sand mastic in Cardonald: local notes
Historic houses like Pollok House (about 2 miles south-east) are a reminder that the area around Cardonald has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. 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.
For site and facilities teams at buildings such as Lourdes Secondary School, its window and door frames need their mastic kept sound, just like a home’s. For an older house near a landmark such as St Nicholas' Cardonald Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
Cardonald is about 2 miles south-east of Renfrew, in Glasgow. Jobs in Cardonald get the same care as everywhere else we work: the old material taken out, joints prepared properly and a 12-month guarantee. Cardonald is one of 183 towns and villages in Glasgow where we work for sand mastic.

Should I try it myself first?
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
