Glazing silicone in Cowcaddens, done properly
Across Cowcaddens, we reseal glazing joints in homes, offices and hotels. Conservatories, rooflights, glass panels and shower screens are all part of the job. If you’re dealing with failed sealant around rooflight glass and split or lifting silicone on glass, we can put it right, on conservatory frames, glass-to-glass joints and glass-to-frame joints alike.
Older stone-built tenements in Scotland’s cities were built with sash and case windows, and plenty still have them. In Cowcaddens, as anywhere, the mastic between frame and wall is what stops draughts and rain getting in.

Cowcaddens: your questions answered
How do repairs to the shared parts of a tenement in Cowcaddens 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 do not.
Can you help a landlord with a rental near Charing Cross (Glasgow) station?
Yes, rental work is part of what we do. Just send an email to info@mrmastic.co.uk and tell us about the property, and we will send you a clear quote.
Is it enough to run a bead over the old sealant?
Topping up is a common cause of leaks. A proper job means cutting out, cleaning and resealing.
What do you need from me for a quote?
Just the basics: the address or postcode, what’s wrong and any access issues. After that, simply email us at info@mrmastic.co.uk.
Can you match the sealant colour?
Most of the time, yes. We will explain which colours are available.
Do you have insurance?
Yes. We are fully insured.
When is the sealant fully cured?
That depends on the sealant used, so follow the cure time we give you when we finish.
Is the work guaranteed?
Our one-year guarantee covers every job.

What happens on the day
We bring everything the job needs with us, so you don’t need to buy or prepare anything. After a quick look at the joints together, we protect the area and start. Most jobs take anything from an hour or two to most of a day, depending on the size of the job. Parking in city streets around Cowcaddens can be tight or controlled, so it helps to know about permits or nearby bays. For flats, mention the door entry system and any shared-stair arrangements.
- First, we trace the leak and check it’s coming through a sealant joint.
- We cut out the failed silicone, taking care of the glass and frame.
- Surfaces are cleaned with a solvent suited to glass and the frame.

Glazing silicone in Cowcaddens: local notes
Much of Glasgow is built from red and blond sandstone, and porous sandstone needs a sealant that will not mark it. Historic houses like Tenement House (about 0.3 miles west) are a reminder that the area around Cowcaddens has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
For landlords with property near Charing Cross (Glasgow) station, leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies. Historic houses such as Tenement House, about 0.3 miles west, show how far back building around Cowcaddens goes, and older homes nearby need a sealant that suits their walls. If you look after a building such as St Aloysius' College, larger buildings have plenty of frames, and the mastic around each one ages.

Surface by surface
Glass-to-frame joints
Silicone at the glass edge seals it into the frame. A failed bead lets water in.
Rooflights
We reseal the glazing joints on rooflights. Leaks from the roof itself need a roofer.
Aftercare tips
How long the joints last depends on use and care. Here’s what we suggest:
- Inspect the sealant on glazing annually
- Use gentle products around the joints
- Run a squeegee over the glass when you’re done
- Open vents or windows to let moisture out
Keep the new joints dry for as long as we advise. From then on, a mild glass cleaner is all it needs.
Act on black or lifting silicone early. Peeling silicone lets water in behind and the leak gets worse.
Why it’s worth doing now in Cowcaddens
A quick bead over the old sealant might stop a drip for a while, but new silicone will not bond to old, and the leak normally returns. A proper reseal is the lasting answer. For landlords in Cowcaddens, damp and leaks can be a Repairing Standard issue, so failed sealant is best replaced before it becomes a complaint.
