Glazing silicone in Lionel
Many conservatory leaks come down to failed sealant, where glass meets frame or frame meets wall. We trace the leak to the joint and reseal it and tell you plainly if the cause is something else. If you are dealing with silicone pulling away from the glass and mouldy sealant around glass panels, we can help, on rooflights, glass-to-frame joints and glass-to-glass joints alike.
In and around a place like Lionel, homes range from older stone-built cottages to newer houses. Wind-driven rain finds any gap around a frame or sill, so the mastic there works hard.
Your job is guaranteed for a year, as with all our work.

Do you need glazing silicone in Lionel?
Sunlight breaks sealant down, especially on conservatory roofs. It goes brittle, cracks and stops sticking to the glass and frame.
Common reasons people contact us include:
- Stained, discoloured glazing silicone
- Split or lifting silicone on glass
- Leaking glazing joints on a rooflight
- Cracked silicone between glass panels
For site and facilities teams at buildings such as Lionel School, the mastic around its windows and doors needs looking after like any other building’s.
What your quote should include
- Which colour the sealant will be
- Whether all the old sealant comes out first
- What product goes in the joint
- How the joint is cleaned and prepared
What happens if it’s left?
Replacing windows or a shower screen isn’t needed for a failed joint. If the glass and frame are sound, new silicone is often all it takes. Around Lionel, 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.
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.

The process
On the day, there’s very little for you to do. Show us the job and we’ll take it from there. The job generally takes a few hours for most jobs from start to finish. Somewhere like Lionel may be a longer drive, and the journey is planned ahead. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- We find where water is getting in and check whether it’s a sealant joint.
- Old silicone is cut away from the glass and frame without scratching either.
- Surfaces are cleaned with a solvent suited to glass and the frame.
- Glazing silicone suited to the joint is applied and tooled.
- The finished joints are checked and, where it’s safe, tested with water.
How to prepare
- Tell us if parking is tricky
- Keep children and pets away from the work area

Related advice
DIY versus a professional finish
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.
When it isn’t the sealant
In fairness, some problems need a different trade:
- A sealed unit that has misted inside
- Structural problems with a conservatory roof
- Frames that have decayed or split
Not sure which it is? You can email us at info@mrmastic.co.uk and we’ll tell you honestly before booking.
Surfaces we seal
- Glass-to-frame joints
- Glass-to-glass joints
- Shower screens

Lionel questions
Does the coastal weather in Lionel affect outside sealant?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. The right product, a clean joint and the right depth all help it cope.
Will you come out to Lionel?
Yes, we do. 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.
Is the work guaranteed?
You get our 12-month guarantee to every job we do.
Why not top up the existing silicone?
Topping up is a common cause of leaks. A proper job means cutting out, cleaning and resealing.
Can you replace a misted double-glazed unit?
We do not replace glass. We look after the sealant joints and can tell you if a unit seems to have gone.
Can landlords and businesses book you?
Yes. We work in homes, commercial premises and hotels.
Do you work for hotels and businesses?
Yes. We can plan bigger jobs in stages.
Do you take out the old sealant first?
Yes, every time. New sealant will not bond properly to old, so any old material comes out before anything new goes in.
Frames and glazing around Lionel
Lionel is within about 1 mile of 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. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that.
Around Lionel, as everywhere, glazing silicone is only as good as the preparation behind it.
