Window mastic in Old Balornock, done properly
Colour matters on a frame. We can seal in white, brown, anthracite grey, black or clear, so the line suits the frame instead of standing out. We work on aluminium frames, window sills and patio & French doors, and common reasons people get in touch are old mastic that has gone black or come away and hard, cracked sealant around windows.
Sash and case windows are a feature of older tenements in all four Scottish cities, though many have since been replaced. Whether you’re in a tenement flat or a house in Old Balornock, the joint between frame and wall is what keeps the weather out.
All of our work is guaranteed for twelve months, in Old Balornock and everywhere else we cover.

When to call us in Old Balornock
Sun, frost and rain wear sealant out. Sunlight dries the surface out, until it loses its stretch and starts to crack.
Most people get in touch after spotting one of these:
- Cracked or shrunken mastic around the frame
- Cracked internal joints between frame and plaster
- Gaps where the sill meets the wall
- Old mastic that has gone black or come away
Managing a site like St. Roch's Secondary School? Then larger buildings have plenty of frames, and the mastic around each one ages.

What sealant work can’t fix

- Penetrating damp from a failed cavity tray or render
- Draughts through the window seals rather than the frame

Windows and doors in Old Balornock
Under the Tenements (Scotland) Act 2004, shared parts of a tenement, such as the roof and outside walls, are looked after by the owners together, and many buildings use a factor to arrange it. Who owns the windows depends on the title deeds. Many older homes in Scotland have sash and case windows, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic.
For landlords with property near Barnhill station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. For an older house near a landmark such as Our Lady of Good Counsel Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Why it’s worth doing now in Old Balornock
A cracked joint around a frame lets rain into the wall. Left long enough, it can stain inside walls, spoil plaster and rot wooden frames. Resealing now is a small job by comparison. Scottish rain finds any gap around a frame or wall joint, and in Old Balornock, damp can spread through stone and plaster before anyone sees it.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you are not sure whether it needs doing, send an email to info@mrmastic.co.uk and we will give you an honest view and a quote.

Questions from Old Balornock
Do you cover Old Balornock for window mastic?
Yes, Old Balornock is within the area we cover. Our work covers the whole of Scotland. You can drop us a line at info@mrmastic.co.uk and tell us what needs doing.
How do repairs to the shared parts of a tenement in Old Balornock get organised?
Most tenements arrange shared repairs through the owners or a property factor. The Tenements (Scotland) Act 2004 covers the common parts where the deeds don’t, and we can quote for the factor or the owners directly.
What sealant do you use?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
Can new window sealant be painted?
Most silicone can’t be painted. If you plan to paint, tell us first and we can use a paintable sealant where it suits the joint.
Can I do it myself?
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.
Do you work on first-floor windows?
Yes, where it’s safe. Higher or awkward frames may need extra access, and we will confirm what’s needed.
Do you work for landlords and businesses?
Yes, often. Several properties can go on one quote, and between tenancies is a good time for the work.
How much does window mastic cost in Old Balornock?
It depends on the job, so we quote each one individually. For a quick quote, drop us a line at info@mrmastic.co.uk with a short description of the job.
DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
What the job involves on each surface
Patio & French doors
Water at the foot of a door frame is not always the mastic: worn seals, blocked drainage slots or a poor threshold detail can be the cause. We check before we reseal.
Window sills
Every drop off the glass ends up on the sill, so the sill ends and the joint under the frame are vital. Each is cleaned out and resealed.
How it works
Most of a good job is in the preparation, so that’s where we spend the time. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours for a few frames, or a day or more for a whole house. For a tenement in Old Balornock, work inside your flat is between us and you, while shared parts may need the factor or neighbours to agree. Tell us which applies when you book.
- First we look at every frame and agree the list.
- The old mastic is cut out and the surfaces cleaned back.
- Deep gaps are filled with backing rod to set the depth.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- We clear up and check every joint is fully closed.
Preparing for the visit
- For indoor joints, keep the area dry beforehand if you can
- Tell us about any previous sealing or DIY attempts
- On commercial sites, let us know about site rules
