Window mastic in Possilpark, done properly
From a single sill to a whole house of windows, you will get a clear quote before any work starts. To get one, send an email to info@mrmastic.co.uk with the number of frames and any access details. We work on timber windows & doors, patio & French doors and uPVC windows, and the jobs we see most are cracked sealant at the sill ends and cold air getting in at the frame edge.
Possilpark is in one of Scotland’s four big cities, where many older buildings are sandstone or granite. Natural stone around older windows needs a sealant that will not mark or attack it, which normally means a neutral-cure product or a traditional sand mastic rather than an acetoxy silicone.
You’re covered for a year from the day we finish. If anything isn’t right with it, send an email to info@mrmastic.co.uk.

Surface by surface
Composite doors
Front doors take the weather head on. Those corners get the most care.
Aluminium frames
Aluminium moves with heat, and the frames are often slimmer than uPVC. A neat, narrow bead in a colour to match suits the frame.
What sealant work cannot fix
We’ll always be straight with you, so here’s what new sealant won’t do:
- Penetrating damp from a failed cavity tray or render
- Rotten timber, which needs a joiner first
- A failed sealed unit that has misted up
Not sure which it is? You can drop us a line at info@mrmastic.co.uk and we’ll tell you honestly.

Do you need window mastic in Possilpark?
Water runs down the glass onto the sill, and the ends of the sill, where it meets the wall, are where it gets in. Failed sealant there lets rain into the wall or behind the frame.
The problems people normally mention when they call are:
- Gaps where the sill meets the wall
- Cracked or shrunken mastic around the frame
- Old mastic that has gone black or come away
- Gaps between the frame and the inside reveal
For an older house near a landmark such as St Teresa's R C Church, the joint between an old wall and a newer frame is normally the first place rain gets in.

The process
Every visit runs the same way: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and tidy away. 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. For a job in Possilpark, tell us the floor, how the door entry system works and where we can park nearby.
- We check each frame and agree which ones need doing.
- The old mastic is cut out and the surfaces cleaned back.
- We fit backing rod in deep gaps so the sealant is the right depth.
- We apply a weatherproof sealant to match the frame and tool it neatly.
- Every joint is checked before we leave.
Getting ready for the visit
- For indoor joints, keep the area dry beforehand if you can
- Keep children and pets away from the work area
- Clear the area around the work

Advice
Questions from Possilpark
How is work on the outside of a tenement in Possilpark generally arranged?
Shared parts of a tenement, such as the roof and outside walls, are normally 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. Your title deeds will say who owns the windows.
I let a flat near Ashfield station. Can you help?
Yes. We work for landlords and letting agents as well as homeowners, and several properties can be quoted together. You can drop us a line at info@mrmastic.co.uk with the details for a clear quote.
Can you seal the gap between the frame and the plaster indoors?
Yes. Outside is the weather seal; inside closes the gap to the plaster. We do one or both.
What do you put in the joint?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We explain the product when we quote.
Do you have sealant for grey or black windows?
Yes. We can use white, brown, anthracite grey, black or clear, so the joint suits the frame.
Do I need to be at home?
We need access to the joints, so we will agree that with you when we book. For inside work, that normally means someone being in.
Is the new sealant paintable?
Not if it’s silicone. We choose the product with your decorating in mind, so mention it when you book.
Can you seal over the old sealant?
No. We remove every bit of old sealant first, so the new sealant bonds properly.
Can I do it myself?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
What window mastic looks like in Possilpark
Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that. With historic houses such as Tenement House (about 1.3 miles south-west) nearby, there’s older building stock in the area around Possilpark as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
For site and facilities teams at buildings such as St Aloysius' College, larger buildings have plenty of frames, and the mastic around each one ages. If you let a flat or house near Ashfield station, renewing tired window mastic between tenants heads off draught and damp complaints.

Why act early in Possilpark
If you are painting or rendering, reseal at the same time. A clean new bead makes new paint or render look finished. Private landlords in Possilpark must meet the Repairing Standard, and damp or leaks can fall short of it, so it’s worth fixing failed sealant before a tenant reports it.
