Glazing silicone for homes and businesses in Netherton
We work across Netherton on glazing joints for homes and businesses. From conservatories to shower screens, it’s the same careful method, with a sealant chosen for the joint. We work on conservatory frames, glass balustrade bases and glass-to-glass joints, and people most often call us about a quick top-up bead that didn’t last and shower screens leaking along the wall or tray.
Tenement flats in Scotland’s cities often have windows high above the street, so the mastic outside can go unchecked for years. For a flat in Netherton, access is the first thing to plan.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

Your questions about glazing silicone in Netherton
I let a flat near Westerton station. Can you help?
Yes, landlords and agents are among the people we work for. You can send an email to info@mrmastic.co.uk with the details for a clear quote.
How is work on the outside of a tenement in Netherton generally arranged?
Shared parts of a tenement, such as the roof and outside walls, are usually repaired with the agreement of the owners, often through a property factor. 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.
Can you match the sealant colour?
We help you choose a colour that suits, from white and clear to greys and other shades. The product needed can limit the range.
What sealant do you use on glazing?
Glass needs a sealant made for glazing. Ours is a neutral-cure glazing silicone with anti-fungal products in bathrooms.
How do I get a quote for glazing silicone in Netherton?
We don’t publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
Does someone need to be in?
For indoor joints, yes, someone needs to let us in. Once we’ve agreed the job, you do not need to watch us work.
Do you take out the old sealant first?
Yes. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Is it enough to run a bead over the old sealant?
Silicone doesn’t stick to silicone and water gets between the layers. We cut out the old sealant first.

What else we do in Netherton
Common problems we fix in Netherton
New silicone over old silicone won’t bond. Plenty of leaks come from a quick top-up over the old bead, and water gets between the layers.
People normally contact us after spotting something like this:
- Rooflight joints letting water in
- Conservatory leaks at frame and glazing joints
- New silicone smeared over old sealant
- Silicone pulling away from the glass
Rented homes near Westerton station change hands often, and a shower screen or conservatory joint that leaks is easier to reseal while the property is empty.
Questions to ask before you book
- What preparation is included
- What the quote includes, VAT included or not
- The length of the guarantee
- Whether you can choose the colour
Keeping the joints in good condition
After the cure time, these simple habits help:
- Open vents or windows to let moisture out
- Look over the glazing joints once a year
- Avoid strong solvents on or near the sealant
- Stick to mild cleaners on glass
Clear the conservatory gutters regularly, so water drains away from the joints. Overflowing gutters can cause leaks of their own.
If silicone on glass has cracked, water is already getting in. Resealing now is a small job compared with fixing water damage later.
What glazing silicone looks like in Netherton
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. Sash and case windows are common in older Scottish homes, often pointed into the wall with traditional sand mastic.
For site and facilities teams at buildings such as Knightswood Secondary School, its window and door frames need their mastic kept sound, just like a home’s. In the older streets around Knightswood St Margaret's Parish Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

What the job involves on each surface
Shower screens
Mouldy or lifting sealant on a screen leaks. A full reseal sorts it.
Glass-to-glass joints
Frameless glass corners and panels are joined with silicone. We reseal with a suitable glazing silicone.
DIY versus a professional finish
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach 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 peels away and traps moisture behind it. Everything old must be removed first.
Why it’s worth doing now in Netherton
Replacing a conservatory roof is major work. If the leak is a failed sealant joint, resealing is far simpler. If it’s the roof itself, we will tell you. In a Scottish city tenement, failed sealant affects more than one flat: a leak can come through the ceiling below, and gaps in shared walls or fire-rated joints matter to every flat.
Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all play a part, and we’ll explain the quote if you ask.

What happens on the day
A visit follows a simple pattern: we look at the joints together, protect the area around them, carry out the job and tidy away. It generally takes a few hours, depending on how many joints need doing. Inside a flat in Netherton, 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 check where the water gets in.
- We remove the old sealant carefully.
- We clean the glass and frame so the new silicone bonds.
- We lay the new bead and tool it smooth.
- Each joint is checked and, where possible, water-tested.
How to prepare
- Mention any tricky access
- Let us know about parking restrictions
- For indoor joints, keep the area dry beforehand if you can
