Window & door mastic in Blairdardie, Glasgow
Mastic around window and door frames, sills and patio doors for homeowners, landlords and businesses in Blairdardie. Fully insured, ARBOMaster approved and guaranteed for a year.
- Rain getting in at the frame or under the sill
- Rushed sealant from a window installation
- Draughty joints inside around the window
Aftercare tips
Joint life depends on how it’s used and looked after. We suggest:
- Make sure the drainage slots are not blocked
- Keep jet washers away from the mastic
- Walk round the house once a year and look at the joints
- Keep timber frames painted
Clean the frames with mild soapy water, and keep solvents and harsh chemicals off the joint.
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. Catching it early keeps the fix to a reseal.
Window mastic for homes and businesses in Blairdardie
Mr Mastic’s applicators have more than 20 years’ experience with window and door sealants. We are fully insured ARBOMaster approved applicators, and every job is covered by a 12-month guarantee. We work on aluminium frames, timber windows & doors and patio & French doors, and people most often call us about whistling draughts around closed windows and old mastic that has gone black or come away.
Blairdardie is in one of Scotland’s four big cities, where many older buildings are sandstone or granite. Stone needs a sealant that suits it, which normally means a neutral-cure product or a traditional sand mastic rather than an acetoxy silicone.
A 12-month guarantee comes as standard, so you’re covered after we’ve gone.

What happens on the day
A visit follows a simple pattern: we check the joints, protect the area around them, carry out the job and clear up. It normally takes a few hours for a handful of frames, longer for a whole house. Many homes in Scotland’s cities are tenement flats, reached through a shared close and up a common stair. In Blairdardie, it helps to know the floor, the door entry arrangements and the nearest parking.
- We start by checking each window and door with you.
- Next the failed sealant is cut away and the joint cleaned.
- Deep gaps are filled with backing rod to set the depth.
- New exterior sealant goes on in a matching colour and is tooled smooth.
- We clear up and check every joint is fully closed.
How to prepare
- Mention any parking rules near the property
- Let us know if you’ve seen damp or leaks
- Where the joints are inside, avoid wetting them before we arrive

Why act early in Blairdardie
Failed mastic isn’t a reason to replace sound windows. Where the frames are sound, new mastic usually deals with draughts and leaks at the edges. If we find failed glass units or worn seals, we’ll tell you. In a tenement flat in Blairdardie, a failed seal is rarely just your problem: water can reach the flat below, and gaps in shared walls or fire-stopping affect the whole stair.
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
Why choose Mr Mastic in Blairdardie

Windows and doors in Blairdardie
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. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that.
Schools such as Knightswood Secondary School are buildings too, and 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 David's Parish Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. For landlords with property near Drumchapel station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

Different surfaces, different methods
Timber windows & doors
Older timber windows in stone or brick can suit sand mastic rather than modern sealant. We can talk through the options.
Patio & French doors
Patio and French doors have the longest joints on most houses. The threshold and the bottom corners take the most water, so they get particular care.
FAQs for Blairdardie
I let a flat near Drumchapel station. Can you help?
Yes, landlords and agents are among the people we work for. You can drop us a line at info@mrmastic.co.uk with the details for a clear quote.
Who arranges sealant work on the shared parts of a tenement in Blairdardie?
It normally goes through the owners together, or through the factor if the building has one. The Tenements (Scotland) Act 2004 sets the rules for common parts if the deeds don’t, and we can quote for the factor or the owners directly.
Will there be a smell?
There can be a smell while the sealant cures, which fades as it sets. Opening a window helps.
Will new mastic stop draughts?
Often, yes. The gap between frame and wall is a common source of draughts, and sealing the inside and outside joints closes that path.
How long does it take to reseal the windows on a house?
That depends on the number of frames, how they’re reached and the state of the old mastic. You will know the timing when we quote.
Do you work in Blairdardie?
Yes. We cover Blairdardie and the rest of Glasgow, as part of our work across South East England, London and Scotland. To book, email us at info@mrmastic.co.uk.
Can you get sealant to suit coloured frames?
Yes, we choose a colour to suit the frame. Grey and black frames get grey or black sealant, and wood-effect frames usually suit brown.
Should I try DIY first?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
