Window mastic in Bellahouston
A cold draught around a closed window often comes from the frame edge. A new joint stops the air getting through and quietens the whistle on windy days. If the draught is through the window seals instead, we will tell you. We work on uPVC windows, timber windows & doors and patio & French doors, and the jobs we see most are draughty joints inside around the window and cold air getting in at the frame edge.
Older stone-built tenements in Scotland’s cities were built with sash and case windows, though many have since been replaced. Whether you’re in a tenement flat or a house in Bellahouston, the joint between frame and wall is what keeps the weather out.
Whatever the size of the job, it’s backed by our one-year guarantee.

For landlords and businesses
We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements and we’ll quote.
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
Why it’s worth doing now in Bellahouston
Once mastic fails, rain can get between the frame and the wall. Over time that can mean damp patches, damaged plaster and rotting timber. A reseal is a much smaller job. For landlords in Bellahouston, damp and leaks can be a Repairing Standard issue, so failed sealant is best replaced before it becomes a complaint.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, along with when we can work on site. Call for a quick quote and we will go through it with you.

How the job changes by surface
Aluminium frames
Metal frames expand in the sun and are often slim, with little room for error. A neat, narrow bead in a colour to match suits the frame.
Window sills
Stone and concrete sills have their own joints, including the one between the sill and the frame above. We seal those with a sealant suited to masonry.
Bellahouston: your questions answered
Do you cover Bellahouston for window mastic?
Yes. Our work covers the whole of Scotland, and Bellahouston is part of that. Just send an email to info@mrmastic.co.uk with a few details of the job.
Who arranges sealant work on the shared parts of a tenement in Bellahouston?
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. Where the title deeds are silent, the Tenements (Scotland) Act 2004 fills the gaps. Your title deeds will say who owns the windows.
Can you work on commercial sites?
Yes. We work in offices, washrooms, hotels and other commercial premises, as well as homes. We can talk about working times when we quote.
Can new window sealant be painted?
It depends on the sealant. Some hybrid sealants can be painted; silicone cannot. Mention any painting plans before work begins.
Do you guarantee window mastic?
Yes, with our 12-month guarantee. Keeping drainage clear and checking the joints yearly helps them last.
Is it OK to seal over old sealant?
No. New silicone will not bond to old silicone, and anything trapped underneath, including mould and water, stays there. We remove it all first.
Are you ARBOMaster approved?
Yes. We are an ARBOMaster approved applicator.
What do you put in the joint?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
Looking after it afterwards
So the new joints stay in good condition:
- Clear any debris from frame drain holes
- Walk round the house once a year and look at the joints
- Repaint timber before it’s bare
- Wash the frames with mild soapy water
Silicone can’t usually be painted, so mention any painting plans before we start. There are paintable sealants for joints that need it.
A failed joint lets water into the wall a little at a time. You might not see it until plaster blows or a damp patch appears inside. Early resealing stops it reaching that point.
What affects the cost of window mastic
Some jobs are bigger than they look, and some smaller. The main factors:
- The old material and how stubborn it is
- Whether the work is at height
- The amount of work
- How many areas need sealing
What it costs depends on the amount of work, how much old material has to come out and access to the work. You’ll have a clear quote before any work starts, so you know where you stand.
Helping us quote
You do not need to know the technical terms. Just tell us:
- Any access issues, like height or stairs
- How many joints, rooms or windows are involved
- What’s wrong with the joints now
- If someone has resealed it before

Window mastic in Bellahouston: local notes
Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that. The Tenements (Scotland) Act 2004 sets out how owners share the upkeep of common parts like the roof and outside walls, and many buildings use a factor to arrange it. Who owns the windows depends on the title deeds.
If you look after a building such as Bellahouston Academy, its window and door frames need their mastic kept sound, just like a home’s. Letting a property close to Dumbreck station? Then sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. In the older streets around Ibrox Parish Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

What happens on the day
At the end, we look at the finished work together and tell you how long to leave it. The visit itself usually takes most of a day for a typical house, less for a few frames, depending on the amount of work. In a city area like Bellahouston, parking may be by permit or pay-and-display, so tell us what’s nearby. If you’re in a flat, let us know how we get in at the street door.
- First, we go round the frames with you and agree the list.
- The old mastic is cut out and scraped back to clean surfaces.
- Where the gap is deep, backing rod goes in first.
- The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
- We tool each bead neatly and check every joint is closed.
Preparing for the visit
- Try not to wet indoor joints just before the visit
- Clear the area around the work
- For business premises, tell us about site rules or sign-in

Advice
Honest limits
New sealant can’t fix everything, and we’d rather say so up front. Sealant will not put right:
- Penetrating damp from a failed cavity tray or render
- A frame that has rotted at the joint
- A sash or casement that will not close properly
If in doubt, email us at info@mrmastic.co.uk and we will say what we think before you book.
