How we handle glazing silicone in Thornwood
A frameless shower screen depends on its silicone. Leaks usually come from the wall joint or the tray joint and both get fresh anti-fungal silicone. We’re often asked to deal with black or yellowed silicone on glass joints and leaks where conservatory glass meets the frame, across glass-to-glass joints, shower screens and glass-to-frame joints.
Older stone-built tenements in Scotland’s cities were built with sash and case windows, and plenty still have them. In Thornwood, as anywhere, the mastic between frame and wall is what stops draughts and rain getting in.
We stand behind the work with a 12-month guarantee, so you’re not left on your own once the job is done.

What the job involves on each surface
Glass-to-frame joints
Glass-to-frame joints need a sealant that bonds to both. We choose a product that suits both.
Conservatory frames
Conservatory frame joints are a common source of leaks. We remove the failed sealant and renew it.
How we quote for glazing silicone
The price is agreed before any work begins. It’s based on:
- Whether there’s mould to deal with
- The old material and how stubborn it is
- The number of rooms or windows
- Which sealant suits the joint
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’ll give you an honest view and a quote.
Helping us quote
To make quoting easier, please include:
- What’s wrong with the joints now
- Any previous sealing or DIY work
- Whether it’s a home or a business
- A few photos by email, if you can
Getting a quote is simple: let us know the job and the location, and roughly how big it is. A few photos by email make the job easier to understand, and we’ll take it from there.
What we do, step by step
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. For most jobs that takes anything from an hour or two to most of a day, depending on the size of the job. Inside a flat in Thornwood, 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.
- First we agree the joints to be done.
- We cut away the failed silicone.
- We clean and prepare the joint.
- New glazing silicone goes in and is finished neatly.
- The joints are checked before we leave.
Preparing for the visit
- Mention any leaks or damp you’ve noticed
- Mention if the joints have been sealed before
- For business premises, tell us about site rules or sign-in

What happens if it’s left?
Glazing joints need a sealant made for the job. A general-purpose tube may not bond well or may react with the frame so we choose a glazing silicone instead. In a tenement flat in Thornwood, a failed seal is rarely just your problem: a leak can come through the ceiling below, and gaps in shared walls or fire-rated joints matter to every flat.
What you pay reflects the work, not a rough estimate. That’s why we ask a few questions first.

What we cannot put right
Some problems need a builder, plumber or other trade rather than us:
- A frame that needs repairing or replacing
- Leaks from the roof covering or flashing (a roofer’s job)
- Condensation trapped between two panes
Not sure which it is? You can drop us a line at info@mrmastic.co.uk and we’ll tell you honestly.
Joints and surfaces we work on
- Conservatory frames
- Rooflights
- Glass-to-glass joints
- Shower screens
- Glass balustrade bases
- Glass-to-frame joints
When to call us in Thornwood
Not every leak is a sealant problem: failed roof panels, slipped glazing bars and blocked gutters cause them too. We find the cause before we seal anything.
If you can see any of these, it’s time to have the joints looked at:
- Mouldy sealant around glass panels
- Glazing silicone that has cracked or come away
- Water getting into a conservatory at the joints
- Shower screens leaking along the wall or tray
Historic houses such as Tenement House, about 2 miles east, show how far back building around Thornwood goes.

Glazing silicone in Thornwood: local notes
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. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that.
Managing a site like Thornwood Primary School? Then larger buildings have plenty of frames, and the mastic around each one ages. Letting a property close to Partick station? Then a shower screen or conservatory joint that leaks is easier to reseal while the property is empty.

FAQs for Thornwood
I let a flat near Partick station. Can you help?
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’ll give you a clear price.
Who arranges sealant work on the shared parts of a tenement in Thornwood?
It generally goes through the owners together, or through the factor if the building has one. The Tenements (Scotland) Act 2004 covers the common parts where the deeds do not.
Do I have to be there?
For indoor joints, yes, someone needs to let us in. Once we have agreed the job, you don’t need to watch us work.
How long will you be here?
Typically it takes a few hours for most jobs. Bigger jobs take longer, and we’ll tell you how long to expect.
How long before the joint can be used?
Many sealants skin over quickly but take longer to cure fully. We will tell you how long to leave the joint before we leave.
Do you offer different sealant colours?
We help you choose a colour that suits. The choice depends on the product the joint needs.
What information do you need?
Only a few details: the address or postcode, what’s wrong and any access issues. Then drop us a line at info@mrmastic.co.uk.
Do the sealants smell?
That depends on the sealant. Some smell for a while, some hardly at all.
DIY sealant or a professional job?
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.
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
