Windows and doors in Provanmill
Historic houses like Provand's Lordship (about 1.6 miles south-west) are a reminder that the area around Provanmill 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. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that.
For landlords with property near Alexandra Parade station, older sash windows in a rental need their mastic kept sound to keep the weather out.

How we handle sand mastic in Provanmill
Sand mastic skins over fairly quickly but full hardening takes longer. Traditionally, sand mastic is left unpainted, so ask us before you decorate. Typical jobs include gaps between timber frames and stone or brick and mastic that needs renewing before redecorating, across stone surrounds, brick reveals and tenement windows.
Older stone-built tenements in Scotland’s cities were built with sash and case windows, and plenty still have them. In Provanmill, as anywhere, the mastic between frame and wall is what stops draughts and rain getting in.
You get a 12-month guarantee, the same in Provanmill as everywhere else we work.

What we’re called out for in Provanmill
Most of it is simply age. Even well-laid mastic needs renewing in time, depending on exposure and upkeep.
Most people get in touch after spotting something like this:
- Weathered mastic on the most exposed windows
- Silicone on a period window that looks wrong
- Mastic round period door frames that has failed
- Patchy fillers round a sash window
Homes close to Our Lady of Good Counsel Church include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
What your quote should include
- How long the guarantee is
- Are they insured?
- What the quote includes, VAT included or not
- Which sealant they’ll use, and why
What happens if it’s left?
Silicone might seem the quicker option, but on period stone or brick it often looks out of place. Sand mastic suits the building and finishes neatly against the masonry. For landlords in Provanmill, damp and leaks can be a Repairing Standard issue, so failed sealant is best replaced before it becomes a complaint.
The cost depends on the amount of work, how much old material has to come out and access to the work. We give a clear quote before any work starts.

How the visit works
Once we’re on site, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. Most jobs then take anything from a few hours to a full day, depending on how many windows. Many homes in Scotland’s cities are tenement flats, reached through a shared close and up a common stair. For a job in Provanmill, tell us the floor, how the door entry system works and where we can park nearby.
- We check the window surrounds and agree which joints need renewing.
- The loose and crumbling mastic is raked out and the joint cleaned.
- Large voids are packed out first, so the mastic isn’t too thick.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- We dress the surface so it sits neatly against the masonry.
Getting ready for the visit

Keeping the joints in good condition
Good habits help new joints last longer. A few tips:
- Avoid patching sand mastic with silicone
- Check the mastic when you check the paintwork
- Do not paint over the new mastic
- Check with your local planning authority if your home is listed
Make sure water drains away from the window surround. Water sitting against the mastic shortens its life.
Renewing mastic before redecorating saves doing it twice. Painting over failed mastic hides the problem for a while.
Surface by surface

Quotes for sand mastic in Provanmill
Some jobs are bigger than they look, and some smaller. The main factors:
- Working hours on commercial sites
- The number of rooms or windows
- How easy the joints are to reach
- The old material and how stubborn it is
Leaving a failed joint usually makes the job bigger, not smaller, as water and mould keep getting in. If you’re not sure whether it needs doing, email us at info@mrmastic.co.uk for an honest opinion and a quote.

Common questions in Provanmill
Can you do sand mastic in Provanmill?
Yes. We work across all of Scotland, and Provanmill is part of that. Just drop us a line at info@mrmastic.co.uk with a few details of the job.
How do repairs to the shared parts of a tenement in Provanmill get organised?
Shared parts of a tenement, such as the roof and outside walls, are usually repaired with the agreement of the owners, often through a property factor. 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.
Will you leave a mess?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
Can old silicone round a sash window be swapped for sand mastic?
Yes, it’s a common request. The old silicone has to come out completely so the mastic can sit properly.
Should I check with the council before work on a listed or conservation-area home?
It’s best to ask your local planning authority first. Sand mastic is often favoured as like for like, but they decide.
What information do you need?
Just the basics: the address or postcode, what’s wrong and any access issues. After that, simply email us at info@mrmastic.co.uk.
Do you offer different sealant colours?
We will suggest a colour to suit the surroundings, from white and clear to greys and other shades. The choice depends on the product the joint needs.
Will there be a smell?
Some sealants have a smell while they cure, but it fades. Ventilation helps.
