About our glazing silicone in Isbister
Many conservatory leaks come down to failed sealant at the glass-to-frame or frame-to-wall joints. We find the joint that’s letting water in and renew it, and if it’s something sealant can’t fix, we’ll tell you. We work on glass-to-frame joints, conservatory frames and shower screens, and the jobs we see most are water tracking down the inner face of the glass and mouldy sealant around glass panels.
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, so the mastic there works hard.
All of our work is guaranteed for twelve months, in Isbister and everywhere else we cover.

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 is fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
Isbister homes and the weather
Isbister 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. Both are hard on glazing joints and frame seals, which can dry out and crack sooner where a building faces the weather. Work on the islands has to be planned around ferry crossings and the weather, so give us as much notice as you can.
For jobs in and around Isbister, choosing the right material for each joint is as important as a tidy finish.

Signs you need glazing silicone in Isbister
Not every leak is a sealant problem: broken panels, roof problems and blocked gutters can all let water in. We find the cause before we seal anything.
It’s worth asking for a quote if you see:
- Failed sealant around rooflight glass
- Glass-to-glass joints that have split
- Water getting into a conservatory at the joints
- Drips on the inside of a conservatory window
In and around Isbister, as anywhere, good glazing silicone starts with a clean, dry, properly prepared joint.
What to look for in a quote
- How long to leave it before use
- How the colour is chosen
- How much experience the applicator has
- What the quote includes, VAT included or not
Keeping the joints in good condition
Simple care keeps the joints in good condition. We recommend:
- Stick to mild cleaners on glass
- Look over the glazing joints once a year
- Act on drips or damp patches early
- Keep scrapers and blades away from the silicone
Look over the glazing joints every year or so. Catching a split early keeps the repair small, before water gets in.
Act on black or lifting silicone early. Peeling silicone lets water in behind and the leak gets worse.
How it works
At the end, we look at the finished work together. The work normally takes anything from an hour or two to most of a day, depending on the size of the job, depending on the size of the job. Outdoor work around Isbister depends on the weather, as sealant needs a dry surface, so an outdoor job can move if the forecast changes. Indoor work goes ahead whatever the weather.
- We trace the leak and confirm it’s a sealant joint.
- The failed silicone is cut out without marking the glass or frame.
- The joint is cleaned and degreased.
- We lay the new bead and tool it smooth.
- Each joint is checked and, where possible, water-tested.
Getting ready for the visit
- Clear the area around the work
- Mention any leaks or damp you’ve noticed
- Let us know about earlier repairs to the joints

Advice
Questions from Isbister
Will you come out to Isbister?
Yes, Isbister is covered. We work across all of Scotland, islands included, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Does the coastal weather in Isbister 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.
What do you put in the joint?
Each joint gets the product that suits it. Movement, water and weather all affect the choice, and we will tell you what we are using.
Can you reseal a frameless shower screen?
Yes. We remove the old sealant and reseal the wall and tray joints.
Will the old sealant be removed?
Yes, every time. New sealant won’t bond properly to old, so the joint is cleaned back first.
Are you insured?
Yes. We are fully insured for every job we do.
Is it enough to run a bead over the old sealant?
Silicone does not stick to silicone, so a top-up soon lets water through. The old bead always comes out first.
How long will you be here?
As a guide, most jobs take a few hours, depending on how many joints need doing. Larger jobs naturally take longer.
