Glazing silicone in Shanklin
Frameless shower screens rely on sealant to keep water in. The joint down the wall and the one along the tray are common leak points and both get fresh anti-fungal silicone. Common call-outs are for black or yellowed silicone on glass joints and leaking glazing joints on a rooflight, across conservatory frames, glass-to-frame joints and shower screens.
Houses in smaller places like Shanklin can stand more in the open than those in a built-up town. The mastic around frames on those walls tends to age faster.
Every job is covered by a one-year guarantee.

How we quote for glazing silicone
Jobs vary more than people expect. The main factors:
- Any working-time requirements on site
- Any mould that needs treating
- How many areas need sealing
- The size of the job
The cost reflects the work involved, not a rough estimate. That’s why we ask about the job first and agree the price before starting.
What we need to know
The more you tell us, the more accurate the quote. When you ask for a quote, tell us:
- Access, such as stairs, a lift or height
- The rough size of the job
- The address or postcode of the job
- Whether it’s a home or a business
For a quick quote, get us on the phone, or send an email if you’d rather. Describe what needs sealing and we’ll explain what’s involved before giving you a price.
Aftercare tips
Aftercare is simple:
- Avoid strong solvents on or near the sealant
- Keep air moving in the conservatory
- Clear the conservatory gutters regularly
- Keep scrapers and blades away from the silicone
On shower screens, wipe or squeegee after use and let the room air. That slows mould growth on the bead.
Cracked glazing silicone means the joint has failed. Renewing it early keeps it simple compared with fixing water damage later.
Can I do it myself?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
When to call us in Shanklin
Sealant laid over old sealant does not last. Many failed joints we see have been topped up rather than cut out leaving a path for water.
These are the problems we’re asked about most:
- Split or lifting silicone on glass
- New silicone smeared over old sealant
- Leaks from the base of a shower screen
- Conservatory leaks at frame and glazing joints
If you live in an older home near St. Paul's Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
Questions to ask before booking
- What the quote includes, VAT included or not
- How the joint is cleaned and prepared
- Whether the sealant suits the joint
- Whether they seal over old material or remove it
What we do, step by step
There is not much for you to do on the day. Point us to the joints and we will get on with it. The work itself takes anything from an hour or two to most of a day, depending on the size of the job from start to finish. A visit to Shanklin is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- First, we check where the water gets in.
- The failed silicone is cut out without marking the glass or frame.
- We clean the glass and frame so the new silicone bonds.
- We lay the new bead and tool it smooth.
- We check the finished joints and test with water where it’s safe.
How to prepare
- Clear items away from the joints we’re working on
- Let us know about stairs, lifts or work at height
- Mention any sign-in or site rules at work premises

Shanklin homes and the weather
Shanklin is close to 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. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For landlords with property near Shanklin station, glazing joints are worth checking at the end of a tenancy, before a small leak grows. If you look after a building such as St Blasius Shanklin CofE Primary Academy, the mastic around its windows and doors needs looking after like any other building’s.

Questions from Shanklin
Is glazing silicone in a coastal place like Shanklin 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. Walls facing the sea are normally the first to need attention.
I let a flat near Shanklin station. Can you help?
Yes. We work for landlords and letting agents as well as homeowners. You can phone 0345 464 0079 or send us an email with the details for a clear quote.
Will there be a smell?
Sometimes, a little. Any smell clears as the sealant cures.
Is a special sealant needed for glass?
We pick a glazing silicone to suit the materials. Neutral-cure silicone is the usual choice, as some acetoxy types can attack certain metals.
Why not top up the existing silicone?
Many leaks we see come from exactly that. We remove the old silicone, clean the joint and reseal.
Where is Mr Mastic based?
We are based in Crawley, and we work across South East England, London and Scotland.
Can you reseal the base of a glass balustrade?
We can, if the base joint is sealed. Send us pictures and we’ll take a look.
What information do you need?
Where the job is, what the problem is and roughly how big it is. Photos by email help too.
How the job changes by surface
Glass balustrade bases
We reseal the joint where the glass meets the base channel. Glass fitting is a separate trade.
Rooflights
We reseal the glazing joints on rooflights. Leaks from the roof itself need a roofer.
