About our glazing silicone in Stornoway
Across Stornoway, we reseal glazing joints in homes, offices and hotels. From conservatories to shower screens, it’s the same careful method. We work on glass balustrade bases, rooflights and glass-to-glass joints, and the jobs we see most are failed sealant around rooflight glass and stained, discoloured glazing silicone.
Older stone-built homes in Scotland often have sash and case or timber windows set in stone. Those suit a traditional sand mastic or a neutral-cure sealant, not an acetoxy silicone that can attack some stone.
A 12-month guarantee comes as standard, so you are covered after we have gone.

Frames and glazing around Stornoway
Stornoway is within about 1 mile of 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. Island jobs need planning around ferries and the weather, so give us as much notice as you can.
For jobs in and around Stornoway, choosing the right material for each joint is as important as a tidy finish.

How the job changes by surface
Glass-to-frame joints
Glass-to-frame joints need a sealant that bonds to both. We choose a product that suits both.
Shower screens
Mouldy or lifting sealant on a screen leaks. A full reseal sorts it.
Work for landlords, hotels and businesses
We also work for property managers and facilities teams. Several sites can be quoted together, and we’re fully insured for the work.
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. A few tips:
- Keep harsh solvents off the silicone
- Check the silicone on glass every year or so
- Clear the conservatory gutters regularly
- Squeegee the shower screen after each use
Look over the glazing joints every year or so. Spotting a crack early means a simpler fix, before water gets in.
Shower screen leaks can go unnoticed. Water can soak into the floor or reach the room below before you spot it.

Advice
Can I do it myself?
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. Everything old must be removed first.
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
Your questions about glazing silicone in Stornoway
Does the coastal weather in Stornoway affect outside sealant?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
Do you cover smaller places like Stornoway?
Yes, smaller places are covered as well as towns. Our work covers the whole of Scotland, including the islands, where work is planned around ferry crossings. Let us know about access, parking and anything unusual about getting there when you book.
Do you reseal glass shower screens?
Yes. The old bead comes off without marking the glass before cleaning and resealing.
Can I do it myself?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs.
How long before the joint can be used?
Many sealants skin over quickly but take longer to cure fully. We will tell you how long to leave the joint.
What information do you need?
Only a few details: the address or postcode, what’s wrong and any access issues. After that, simply email us at info@mrmastic.co.uk.
Do you work for letting agents?
Yes, we do. We work in homes, commercial premises and hotels, and we’re fully insured.
How much does glazing silicone cost in Stornoway?
We do not publish prices, because the cost depends on the job: its size, the old material, access and the product needed. You will get a clear quote before we start.
Do you need glazing silicone in Stornoway?
Glass and frames expand and contract with the temperature at different rates. In time, the sealant splits or pulls away.
These are the problems we’re asked about most:
- Sealant that was laid over old silicone and failed
- Leaks from the base of a shower screen
- Failed joints on frameless glass
- Water tracking down the inner face of the glass
In and around Stornoway, as anywhere, good glazing silicone starts with a clean, dry, properly prepared joint.

Leave it or put it right?
A leaking joint won’t fix itself. Water can damage frames, walls, flooring and furniture so early action saves a bigger repair. 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.
Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part.
