How we handle glazing silicone in Shawbost
Glass, frames and walls all move at different rates, so the sealant between them does a lot of work. Once it splits or comes away, water finds a way through. We replace it with a glazing silicone that suits the glass and frame. We work on conservatory frames, glass balustrade bases and glass-to-frame joints, and the jobs we see most are silicone pulling away from the glass and mouldy sealant around glass panels.
Many older Scottish homes still have timber windows set into stone walls. Those suit a traditional sand mastic or a neutral-cure sealant, not an acetoxy silicone that can attack some stone.
Big or small, you get the same 12-month guarantee.

Do you need glazing silicone in Shawbost?
Silicone will not bond to a dirty surface. Where the joint wasn’t cleaned and degreased the sealant may lift within a few years.
Keep an eye out for these signs:
- Black or yellowed silicone on glass joints
- A quick top-up bead that didn’t last
- Leaking glazing joints on a rooflight
- Silicone pulling away from the glass
In and around Shawbost, as anywhere, good glazing silicone starts with a clean, dry, properly prepared joint.

Glazing silicone in Shawbost: local notes
Shawbost is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on glazing joints and frame seals, which can dry out and crack sooner where a building faces the weather. Shawbost is in the west of Scotland, which is wetter than the east, so there’s plenty of rain for glazing joints and frame seals to keep out.
Whether the job is in Shawbost itself or nearby, the right material for each joint matters as much as a neat finish.

What the job involves on each surface
Shower screens
Most shower screen leaks come from the wall or tray joint. Both are resealed with anti-fungal silicone.
Conservatory frames
Conservatory frame joints are a common source of leaks. We remove the failed sealant and renew it.
Should I try it myself first?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
If you’ve already had a go yourself, that’s fine. We cut it out and start again.

When it isn’t the sealant

- Water coming through the roof rather than a sealant joint
- A sagging or failing conservatory roof
- Frames that have decayed or split
Not sure which it is? You can drop us a line at info@mrmastic.co.uk and we’ll tell you honestly before booking.
What we seal
- Glass-to-glass joints
- Glass balustrade bases

Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Clean glass with a mild cleaner and a soft cloth
- Wipe the screen down after showering
- Act on drips or damp patches early
- Clear the conservatory gutters regularly
Do not use blades or scrapers near the bead when cleaning the glass. Stick to a soft cloth.
Shower screen leaks can go unnoticed. Water can soak into the floor or reach the room below before you spot it.
What happens if it’s left?
You don’t need new glazing because the sealant has gone. If the glass and frame are sound, new silicone is often all it takes. Around Shawbost, 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.
