Sand mastic for homes and businesses in Cowcaddens
Sand mastic skins over fairly quickly but full hardening takes longer. Traditionally, sand mastic is left unpainted and we’ll advise if you are redecorating. Typical jobs include gaps round a timber door in stone or brick and wind and rain getting in round a sash window, across tenement windows, sash and case windows and timber door frames.
Older stone-built tenements in Scotland’s cities were built with sash and case windows, and plenty still have them. Whether you’re in a tenement flat or a house in Cowcaddens, the joint between frame and wall is what keeps the weather out.

Aftercare tips
To keep the joints looking good and working properly:
- Keep sills and gutters clear so water drains away
- Ask a joiner to look at soft timber first
- Don’t run silicone over sand mastic
- Avoid heavy scraping on the mastic joint
Don’t run silicone over the new mastic. If you see a crack, ask us to take a look before trying a quick fix.
Crumbling mastic lets rain into the joint. It can soak into the frame and the surrounding masonry, so renewing it early is worth it.
What we can’t put right
Honest advice matters more to us than a booking, so here’s what new sealant won’t do:
- Decayed frames that need repair
- Planning or listed building consent (your local planning authority decides)
- Crumbling stone or brickwork round the window
If in doubt, email us at info@mrmastic.co.uk and we will say what we think before you book.
Surfaces we seal
- Tenement windows
- Stone surrounds
- Brick reveals
- Period & listed homes
- Timber door frames
- Sash and case windows
Work for landlords, hotels and businesses
We also work for property managers and facilities teams. We can quote a run of properties together, and we are fully insured.
Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. We can quote for more than one property at once.
Leave it or put it right?
Draughts round a sash window aren’t always the sashes. Gaps between the frame and the wall can be just as bad and new mastic seals them. For landlords in Cowcaddens, damp and leaks can be a Repairing Standard issue, so failed sealant is best replaced before it becomes a complaint.
What it costs depends on the size of the job, how hard the old material is to remove and access to the work. You will have a clear quote before any work starts.

- Arbo and Everbuild products
- Old sealant always removed completely

Your questions about sand mastic in Cowcaddens
Who arranges sealant work on the shared parts of a tenement in Cowcaddens?
Shared parts of a tenement, such as the roof and outside walls, are generally repaired with the agreement of the owners, often through a property factor. Where the title deeds are silent, the Tenements (Scotland) Act 2004 fills the gaps. Windows often belong to the individual flat, but it’s worth checking your deeds.
Can you do sand mastic in Cowcaddens?
Yes. Our work covers the whole of Scotland, and Cowcaddens is part of that. Just email us at info@mrmastic.co.uk with a few details of the job.
Will the old sealant be removed?
Yes. We cut out all the old sealant and clean the joint before applying anything new.
What do you put in the joint?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
How do I get a quote for sand mastic in Cowcaddens?
Every job is different, so each one gets its own quote. To get one, send an email to info@mrmastic.co.uk with a short description of the job.
Can you seal over the old sealant?
No. The old sealant always comes out first, so the new joint bonds to clean surfaces.
What guarantee comes with the work?
You get our 12-month guarantee on every job.
What should I tell you?
A short description and the location. We’ll ask anything else we need to know.
How it works
Most of a good job is in the preparation, so that’s where we spend the time. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours per window, depending on the condition of the joints. In a Scottish city, a lot of jobs are in tenement flats, up a common stair from a shared close. In Cowcaddens, it helps to know the floor, the door entry arrangements and the nearest parking.
- First we agree which joints need doing.
- Old mastic and any loose material are raked out.
- We pack any deep voids first.
- The sand mastic is mixed and pressed into the joint by hand.
- The surface is finished to suit the stone or brick.
Preparing for the visit
- Clear items away from the joints we are working on
- Mention any sign-in or site rules at work premises
- Tell us about any previous sealing or DIY attempts

DIY sealant or a professional job?
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
