Balornock: your questions answered
I let a flat near Bishopbriggs station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. Just drop us a line at info@mrmastic.co.uk with the address and what needs doing, and we’ll give you a clear quote.
How is work on the outside of a tenement in Balornock usually arranged?
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. 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.
Do you come to Balornock?
Yes. We cover Balornock and the rest of Glasgow, as part of our work across South East England, London and Scotland. For a quote, email us at info@mrmastic.co.uk.
Can I do it myself?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. If it doesn’t work out, we can redo it.
Can you do upstairs windows?
Yes, where it’s safe. Higher or awkward frames may need extra access, and we’ll confirm what’s needed.
Can I add another job to the visit?
Yes, we can. Several rooms, windows or areas can go on one quote.
Can you seal over the old sealant?
No. We remove every bit of old sealant first, so the new joint bonds to clean surfaces.
Can I paint over the new sealant?
That depends on the product. Some hybrid sealants can be painted; silicone can’t. Mention any painting plans before work begins.

What affects the cost of window mastic
Your quote is based on your job. We take into account:
- How much there is to do
- Any mould that needs treating
- How many rooms, windows or areas are involved
- The old material and how stubborn it is
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.
What we need to know
A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- Any previous sealing or DIY work
- The rough size of the job
- The address or postcode of the job
- What the problem is, such as mould, gaps, leaks or cracking
To get a quote, email us at info@mrmastic.co.uk with the location and a short description of the problem. We’ll send you a clear quote before any work starts.
How it works
When we get to you, we check the joints match what you told us. If anything is different, we explain it before carrying on. Most jobs then take a few hours for a handful of frames, longer for a whole house. Inside a flat in Balornock, the job is planned with you; outside, shared parts may need the factor or other owners involved. It helps to know which it is when you get in touch.
- We check each frame and agree which ones need doing.
- Next the failed sealant is cut away and the joint cleaned.
- Deep gaps are filled with backing rod to set the depth.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- Finally we tidy up and check each joint.
Getting ready for the visit
- Let us know about stairs, lifts or work at height
- On commercial sites, let us know about site rules
- Let us know about earlier repairs to the joints

Should I try it myself first?
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.
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so tell us about it when you ask for a quote.
What sealant work cannot fix
We won’t take on work that won’t last, so these are the limits:
- A frame that has rotted at the joint
- A failed sealed unit that has misted up
- Damp coming through the wall itself rather than the frame joint
If in doubt, send an email to info@mrmastic.co.uk and we will say what we think before you book.

For landlords and businesses
From a single let to a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a one-year guarantee.
We also work for property managers and facilities teams. We can quote a run of properties together, and we are fully insured.
Why deal with it now?
Draughts and leaks don’t always mean new windows. If the frames and glass are in good order, resealing the joints is often all that’s needed. Problems with the glass or gaskets are for a window company, and we’ll say so. Scottish rain finds any gap around a frame or wall joint, and in Balornock, damp can spread through stone and plaster before anyone sees it.
What it costs depends on the amount of work, how much old material has to come out and how easy the joints are to reach. You’ll have a clear quote before any work starts.
Why us?
- Neat joints and a tidy finish
- A 12-month guarantee on all work
- Trusted Arbo and Everbuild sealants
- Anti-fungal silicone where joints get wet

What the job involves on each surface
Timber windows & doors
Soft or rotten wood can’t be sealed successfully. We will point out any rot we find, as that’s a job for a joiner.
uPVC windows
We clean the frame edge carefully so the plastic isn’t marked, then the sealant goes in between frame and wall.
What window mastic looks like in Balornock
The Tenements (Scotland) Act 2004 sets out how owners share the upkeep of common parts like the roof and outside walls, often through a property factor. Windows normally belong to the flat, but the title deeds have the final say. Glasgow’s tenements are largely red and blond sandstone, and sandstone is porous, so any sealant against it has to be one that won’t stain or attack it.
Letting a property close to Bishopbriggs station? Then cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. In the older streets around Colston Wellpark Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
