How we handle glazing silicone in Castletown
Frameless shower screens rely on sealant to keep water in. Leaks generally come from the wall joint or the tray joint, and we reseal both. We work on shower screens, glass balustrade bases and conservatory frames, and people most often call us about silicone pulling away from the glass and cracked silicone between glass panels.
In and around a place like Castletown, homes range from older stone-built cottages to newer houses. Wind-driven rain finds any gap around a frame or sill.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

Why act early in Castletown
You don’t need new glazing because the sealant has gone. Sound glass and frames usually just need resealing, and we will tell you if that’s not the case. Around Castletown, water from a failed joint in an older stone home can soak into timber and plaster.
What it costs depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before work begins, so you know where you stand.

- Fully insured
- Homes, businesses and hotels

Castletown: your questions answered
Do you cover Castletown for glazing silicone?
Yes, Castletown is within the area we cover. Our work covers the whole of Scotland. You can email us at info@mrmastic.co.uk and let us know what needs doing, and we will give you a clear price.
Is glazing silicone in a coastal place like Castletown any different?
Near the sea, outside joints face more wind, rain and salt than they would inland, so the choice of sealant and the preparation matter even more. It’s worth checking the walls that face the sea first.
Will the old sealant be removed?
Yes, every time. New silicone does not stick to old silicone, so any old material comes out before anything new goes in.
Do the sealants smell?
It depends on the product. Some products have a noticeable smell, others very little.
Do you fit new glass or sealed units?
No. We renew the sealant. A glazier replaces glass and units.
Where are you based?
Our base is Crawley, with over 20 years’ experience. Our area covers South East England, London and Scotland.
Do I have to be there?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
What sealant do you use on glazing?
A glazing-grade silicone is best. We use neutral-cure glazing silicone with anti-fungal products in bathrooms.
Quotes for glazing silicone in Castletown
You will get a clear quote before we start. It takes into account:
- How many rooms, windows or areas are involved
- Whether old sealant or filler has to be cut out
- Whether there’s mould to deal with
- The size of the job
There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote.
What we need to know
When you call or email, these details help:
- Any access issues, like height or stairs
- What’s wrong with the joints now
- The rough size of the job
- If it’s domestic, commercial or a hotel
The more we know about the job, the more useful the quote. Tell us where the job is, what’s wrong and how much there is, and add photos by email if you can.
When something else is needed
New sealant can’t fix everything, and we’ll tell you before any work starts. It will not solve:
- Misting between the panes of a double-glazed unit (a failed unit for a glazier)
- Frames that have decayed or split
- A roof that has moved or dropped
If in doubt, drop us a line at info@mrmastic.co.uk and we will say what we think.
Where we work in Castletown
- Conservatory frames
- Glass-to-glass joints
- Shower screens
- Glass-to-frame joints
- Glass balustrade bases
- Rooflights
Can I do it myself?
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
Do you need glazing silicone in Castletown?
Silicone will not bond to a dirty surface. Where the joint wasn’t cleaned and degreased, the bead can peel away early.
These are the problems we are asked about most:
- A quick top-up bead that didn’t last
- Shower screens leaking along the wall or tray
- Leaking glazing joints on a rooflight
- Mouldy sealant around glass panels
In the older streets around St Trothan's Church, the joint between an old wall and a newer frame is normally the first place rain gets in.

How the job changes by surface
Conservatory frames
Frame joints face sun and rain all year. A fresh bead seals them again.
Rooflights
We reseal the glazing joints on rooflights. Leaks from the roof itself need a roofer.

Windows and doors in Castletown
Castletown 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. 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.
In and around Castletown, as anywhere, good glazing silicone starts with a clean, dry, properly prepared joint.

- First, we check where the water gets in.
- The failed silicone is cut out without marking the glass or frame.
