How we handle glazing silicone in Clestrain
Glazing joints need a sealant made for glass. We use a neutral-cure glazing silicone that is suited to glass and the frame, finished with a neat, even bead. We work on rooflights, glass-to-frame joints and glass balustrade bases, and common reasons people get in touch are leaks where conservatory glass meets the frame and stained, discoloured glazing silicone.
Across smaller places in Scotland, homes range from stone and harled cottages to newer houses, many standing in the open. Exposed frames and sills take the full force of wind-driven rain.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

Keeping the joints in good condition
A little care helps the new joints last. Our advice:
- Keep air moving in the conservatory
- Clear the conservatory gutters regularly
- Check the silicone on glass every year or so
- Wipe the screen down after showering
Squeegee a shower screen after each shower and keep the room ventilated. It helps stop mould getting into the silicone.
Don’t leave lifting or mouldy silicone on glazing. Peeling silicone lets water in behind and the leak gets worse.
Clestrain: your questions answered
Does living near the coast affect glazing silicone in Clestrain?
Near the sea, outside joints face more wind, rain and salt than they would inland, so the choice of sealant and the preparation matter even more. It’s worth checking the walls that face the sea first.
Is Clestrain in your area for glazing silicone?
Yes, Clestrain is within the area we cover. Our work covers the whole of Scotland. You can drop us a line at info@mrmastic.co.uk and tell us what needs doing.
Is it worth trying it myself?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs.
What do you put in the joint?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference, and we’ll explain our choice.
Where are you based?
Our base is in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
Do you reseal glass shower screens?
Yes, it’s a common job. The screen is resealed with anti-fungal silicone suited to bathrooms.
Can landlords and businesses book you?
Yes, often. Several properties can be quoted together, and between tenancies is a good time for the work.
Is balustrade sealant something you do?
We can, if the base joint is sealed. Photos help us see what’s there when you email us at info@mrmastic.co.uk.
Should I try it myself first?
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.

How the visit works
We work through the job in order: 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, and the area is left clean. For a place like Clestrain, longer drives are planned in advance. Mention tracks, gates, ferries or anything else about the route.
- We start by finding the leak and making sure sealant is the cause.
- 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.
- New glazing silicone goes in and is tooled to a neat finish.
- We look over every joint and, where we can, test it with water.
How to prepare
- Where the joints are inside, avoid wetting them before we arrive
- Mention any tricky access
- For business premises, tell us about site rules or sign-in

What we can’t put right
We’d rather tell you now than do work that won’t last, so these are the limits:
- A broken pane or roof panel
- A frame that needs repairing or replacing
- A sagging or failing conservatory roof
Not sure which it is? You can send an email to info@mrmastic.co.uk and we’ll tell you honestly.

Common problems we fix in Clestrain
Heat and cold make glass and frames move at different rates. In time, the sealant splits or pulls away.
If you can see any of these, it’s time to have the joints looked at:
- Water getting into a conservatory at the joints
- Leaking glazing joints on a rooflight
- Drips on the inside of a conservatory window
- Glazing silicone that has cracked or come away
For jobs in and around Clestrain, choosing the right material for each joint is as important as a tidy finish.

What the job involves on each surface
Glass balustrade bases
The base of a glass balustrade is generally sealed. Failed sealant there lets water collect.
Glass-to-glass joints
Where two panes meet, the silicone joint takes all the movement. The bead needs to be tidy and fully bonded.
Leave it or put it right?
Fixing a leaking screen early protects what’s underneath. A small leak can reach the floor below before it shows. Out of town in Scotland, exposed walls take a lot of weather, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
What it costs depends on the size of the job, how much old material has to come out and how easy the joints are to reach. We give a clear quote before we start, so you know where you stand.

Frames and glazing around Clestrain
Clestrain is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That is hard on glazing joints and frame seals, especially on the side facing the sea. Work on the islands has to be planned around ferry crossings and the weather, so the more notice, the better.
Around Clestrain, as everywhere, glazing silicone is only as good as the preparation behind it.
