Glazing silicone in Banknock
Our work covers conservatory joints, rooflights and glass panels plus shower screens and the bases of glass balustrades. The old sealant comes out, the joint is cleaned and new silicone goes in. We work on rooflights, conservatory frames and glass balustrade bases, and common reasons people get in touch are leaking glazing joints on a rooflight and stained, discoloured glazing silicone.
Mastic can only go onto a dry joint, so outside work in Banknock depends on the weather. Let us know about access to every frame, including any upstairs.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

Why deal with it now?
A leaking joint will not fix itself. Water can damage frames, walls, flooring and furniture, so it pays to deal with it early. Exposed walls in smaller Scottish places take a lot of wind and rain, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference.

Looking after it afterwards
Good habits help new joints last longer. A few tips:
- Squeegee the shower screen after each use
- Open vents or windows to let moisture out
- Stick to mild cleaners on glass
- Do not leave a drip for the next storm
Check the joints once a year. Spotting a crack early means a simpler fix, before water gets in.
A small conservatory leak soon spreads. Water travels along the frame and into the wall, so get it looked at when you first see it.
What affects the quote in Banknock
We quote each job individually. These are the things that affect it:
- The size of the job
- Whether old sealant or filler has to be cut out
- Working hours on commercial sites
- Any mould that needs treating
Leaving a failed joint normally makes the job bigger, not smaller, as water and mould keep getting in. If you are not sure whether it needs doing, drop us a line at info@mrmastic.co.uk for an honest opinion and a quote.
What to tell us for a quote
You do not need to know the technical terms. It helps if you can tell us:
- What’s wrong with the joints now
- If it’s domestic, commercial or a hotel
- Roughly how big the job is
- Photos by email, if that’s easy

Frames and glazing around Banknock
Sash and case windows are common in older Scottish homes, often pointed into the wall with traditional sand mastic. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and sound outside sealant is part of that.
If you look after a building such as Abronhill High School, its window and door frames need their mastic kept sound, just like a home’s. Letting a property close to Cumbernauld station? Then leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies. Homes close to Haggs Parish Church include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame.

FAQs for Banknock
I let a flat near Cumbernauld station. Can you help?

Can you do glazing silicone in Banknock?
Yes, Banknock is within the area we cover. Our work covers the whole of Scotland. Just drop us a line at info@mrmastic.co.uk with a few details of the job.
Is a special sealant needed for glass?
Glass needs a sealant made for glazing. We use neutral-cure glazing silicone and anti-fungal silicone in wet areas.
Is it worth trying it myself?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. If it doesn’t work out, we can redo it.
Do you fit new glass or sealed units?
No. We renew the sealant. A glazier replaces glass and units.
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.
