Glazing silicone in Overtown
Glazing silicone that has yellowed, blackened or come away spoils the look and lets water in. We remove it without scratching the glass or frame before the new bead goes in. Typical jobs include silicone pulling away from the glass and conservatory leaks at frame and glazing joints, on glass-to-glass joints, glass balustrade bases and glass-to-frame joints.
Mastic can only go onto a dry joint, so outside work in Overtown depends on the weather, and longer journeys are planned in advance. Tell us about access to all the windows and doors, upstairs included.
Every job comes with our 12-month guarantee.

Windows and doors in Overtown
Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that. With historic houses such as Cambusnethan House (about 1.4 miles west) nearby, there’s older building stock in the area around Overtown as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
If you let a flat or house near Wishaw station, leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies. For an older house near a landmark such as Overtown 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
Glass-to-glass joints
Silicone joins glass panels in many frameless designs. We renew it with a clear or matching glazing silicone.
Shower screens
Most shower screen leaks come from the wall or tray joint. Both are resealed with anti-fungal silicone.

Looking after it afterwards
Good habits help new joints last longer. A few tips:
- Inspect the sealant on glazing annually
- Avoid strong solvents on or near the sealant
- Keep air moving in the conservatory
- Don’t use a blade near the sealant
Follow the cure time we give you before the joints get wet so the silicone can set properly. After that, clean glass with a mild cleaner.
Damp patches, drips and condensation along a joint are worth checking. The cause may be sealant or another part, and we will tell you which.
Common questions in Overtown
Can you do glazing silicone in Overtown?
Yes, Overtown is within the area we cover. We work across all of Scotland. Just send an email to info@mrmastic.co.uk with a few details of the job.
I let a flat near Wishaw station. Can you help?
Yes. We work for letting agents and landlords as well as householders, and several properties can go on one quote. You can drop us a line at info@mrmastic.co.uk with the details for a clear quote.
How long will you be here?
It depends on the size of the job, but as a guide it takes anything from an hour or two to most of a day, depending on the size of the job. We will tell you when we quote.
Are you insured?
Yes. We’re fully insured for domestic and commercial work.
What do you need from me for a quote?
The location, the problem and the rough size of the job. If you can, email a few photos.
Will you leave a mess?
We keep the work tidy. Nearby surfaces are protected, and the area is left clean when we finish.
Can you replace a misted double-glazed unit?
That’s not something we do. A misted unit has failed inside, and a glazier needs to replace it.
Should I try DIY first?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.
When it is not the sealant
Sealant is not the answer to every problem, and we’d rather say so up front. Sealant will not put right:
- Cracked or broken glass
- A sealed unit that has misted inside
- Leaks from the roof covering or flashing (a roofer’s job)
If you’re not sure, just email us at info@mrmastic.co.uk and we will give you a straight answer.

What affects the quote in Overtown

We don’t show prices on the website, because the cost depends so much on the job itself. Call for a quick quote.
What to tell us for a quote
The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:
- Whether it has been sealed before

- Where the property is
- Whether it’s a home or a business

What happens on the day
At the end, we look at the finished work together. The work normally takes a few hours, depending on how many joints need doing, depending on the size of the job. In smaller Scottish places, parking is usually less of an issue than access and distance. Tell us how to find the property and how to reach the work.
- We start by finding the leak and making sure sealant is the cause.
- The old sealant is removed from the glass and frame without scratching them.
- We clean the joint with a solvent that suits the glass and frame.
- Glazing silicone suited to the joint is applied and tooled.
- The finished joints are checked and, where it’s safe, tested with water.
Before we arrive
- Where the joints are inside, avoid wetting them before we arrive
- Keep pets and children clear of the area while we work
- Mention any parking rules near the property

Why it’s worth doing now in Overtown
Silicone around glazing needs the right product. A general-purpose tube may not bond well or may react with the frame so we choose a glazing silicone instead. Around Overtown, water from a failed joint in an older stone home can soak into timber and plaster, which is a far bigger job than the sealant.
The cost depends on the amount of work, how much old material has to come out and access to the work. You will have a clear quote before any work starts.

What we are called out for in Overtown
UV light ages silicone, especially on conservatory roofs. Old silicone hardens, cracks and loses its grip to the glass and frame.
The problems people generally mention when they call include:
- New silicone smeared over old sealant
- Water tracking down the inner face of the glass
- Conservatory leaks at frame and glazing joints
- Leaking glazing joints on a rooflight
For site and facilities teams at buildings such as St Aidan's High School, larger buildings have plenty of frames, and the mastic around each one ages.
