How we handle glazing silicone in Grindiscol
We do not replace glass, and misting between panes means a failed sealed unit. What we do is the silicone around the glass and that’s often where the water gets in. If you have leaks where conservatory glass meets the frame and stained, discoloured glazing silicone, we can help.
Outdoor sealant needs a dry surface, so window work around Grindiscol is planned around the weather. Let us know about access to every frame, including any upstairs.
The work is covered for a year after we finish. If anything is not right with it, drop us a line at info@mrmastic.co.uk.

Grindiscol homes and the weather
Grindiscol is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That is hard on glazing joints and frame seals, especially on the side facing the sea. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and sound outside sealant is part of that.
Managing a site like Anderson High School? Then larger buildings have plenty of frames, and the mastic around each one ages. If you live in an older home near Bressay Kirk, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
Grindiscol is in the Shetland Islands. We provide glazing silicone to homes and businesses in Grindiscol, as part of our work across the Shetland Islands. Across the Shetland Islands, we cover 63 places, and Grindiscol is one of them.

Aftercare tips
How long the joints last depends on use and care. Here’s what we suggest:
- Ventilate the conservatory to cut condensation
- Use gentle products around the joints
- Get a new leak looked at quickly
- Stick to mild cleaners on glass
Look over the glazing joints every year or so. Catching a split early keeps the repair small.
Shower screen leaks can go unnoticed. Water can soak into the floor or reach the room below long before you see it.

From a single let to a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.

How the job changes by surface
Shower screens
Silicone holds the water in on frameless screens. We reseal without scratching the glass.
Rooflights
We reseal the glazing joints on rooflights. If the leak is from the roof around it, a roofer needs to look.

Advice

What happens if it’s left?
Dealing with a leaking shower screen early protects the floor and ceiling. A small leak can reach the floor below before you notice. Exposed walls in smaller Scottish places take a lot of wind and rain, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
Leaving a failed joint generally makes the job bigger, not smaller. If you’re unsure, send an email to info@mrmastic.co.uk and we will give you an honest view and a quote.

Should I try it myself first?
Some sealant jobs are within reach of a careful DIYer, 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.
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so just mention it when you contact us.
