About our glazing silicone in Cathcart
We work across Cathcart on glazing joints for homes and businesses. Conservatories, rooflights, glass panels and shower screens are all part of the job. Common call-outs are for rooflight joints letting water in and water getting into a conservatory at the joints, on shower screens, glass-to-glass joints and glass-to-frame joints.
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 Cathcart, the joint between frame and wall is what keeps the weather out.
Each job carries a 12-month guarantee, large or small.

Can I do it myself?
A DIY attempt does not rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
Do you need glazing silicone in Cathcart?
Using a sealant not made for glass causes many failures. Some products do not bond well to glass, and acetoxy types can attack some frame materials.
Signs it’s time to call us include:
- Shower screens leaking along the wall or tray
- Water running down inside the glass
- Glass-to-glass joints that have split
- Split or lifting silicone on glass
In the older streets around Cathcart South Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
Questions to ask before you book
- Whether you can choose the colour
- Whether VAT is included
- How the surfaces are prepared before sealing
- Whether the sealant suits the joint

Keeping the joints in good condition
To keep the joints looking good and working properly:
- Check the gutters above the glazing for debris
- Do not leave a drip for the next storm
- Inspect the sealant on glazing annually
- Run a squeegee over the glass when you are done
Keep conservatory gutters clear, so water drains away from the joints. Overflowing gutters can cause leaks of their own.
A leaking shower screen may not show at first. It can damage the floor or the ceiling below long before you see it.
Cathcart questions
Do you cover Cathcart for glazing silicone?
Yes. We work across all of Scotland, and Cathcart is part of that. Just email us at info@mrmastic.co.uk with a few details of the job, and we’ll give you a clear price.
Who arranges sealant work on the shared parts of a tenement in Cathcart?
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 do not. Your title deeds will say who owns the windows.
Where are you based?
We are based in Crawley, and we work across South East England, London and Scotland.
Is a special sealant needed for glass?
A neutral-cure glazing silicone suited to glass and the frame. In bathrooms, we use anti-fungal silicone.
What sealant do you use?
Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We’ll tell you what we are using and why.
Do you replace glass?
No. A misted unit has failed inside and needs replacing by a glazier.
Will resealing stop my conservatory leaking?
In many cases, as long as sealant is the cause. We trace the leak first before any sealing.
Will it make a mess?
We keep the work tidy. We protect what’s around the joints.
What happens on the day
On the day, there’s very little for you to do. Point us to the joints and we’ll get on with it. The work itself takes anything from an hour or two to most of a day, depending on the size of the job, including the tidy-up. Inside a flat in Cathcart, the job is planned with you; outside, shared parts may need the factor or other owners involved. Tell us which applies when you book.
- First, we trace the leak and check it’s coming through a sealant joint.
- Old silicone is cut away from the glass and frame without scratching either.
- We clean the joint with a solvent that suits the glass and frame.
- New glazing silicone goes in and is tooled to a neat finish.
- The finished joints are checked and, where it’s safe, tested with water.
Before we arrive
- Clear items away from the joints we’re working on
- Let us know about earlier repairs to the joints
- Tell us about any water getting in

Glazing silicone in Cathcart: local notes
The west of Scotland is wetter than the east, so there’s plenty of rain for glazing joints and frame seals to keep out. Historic houses like Pollok House (about 2.1 miles west) are a reminder that the area around Cathcart has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
Rented homes near Cathcart station change hands often, and leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies. If you look after a building such as Shawlands Academy, the mastic around its windows and doors needs looking after like any other building’s.

Different surfaces, different methods
Shower screens
Silicone holds the water in on frameless screens. We renew it without marking the glass.
Rooflights
Rooflight leaks can come from the sealant or the roof. We check which it is.
What we can’t put right
In fairness, some problems need a different trade:
- Misting between the panes of a double-glazed unit (a failed unit for a glazier)
- Failed flashing around a conservatory
- Glass that needs replacing
