Glazing silicone in St John's, done properly
Our work covers conservatory joints, rooflights and glass panels plus shower screens and the bases of glass balustrades. The old sealant comes out, the joint is cleaned and new silicone goes in. If you are dealing with mouldy sealant around glass panels and rooflight joints letting water in, we can put it right.
In a smaller place like St John's, some walls face open ground and catch the full force of the weather, so exposed windows and doors face the weather head on. The mastic around frames on those walls tends to age faster.
You get a one-year guarantee, the same in St John's as everywhere else we work.

Your questions about glazing silicone in St John's
Will you come out to St John's?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Can you help a landlord with a rental near Woking station?
Yes, rental work is part of what we do. Just phone 0345 464 0079 or send us an email and tell us about the property, and we’ll give you a clear price.
Do you take out the old sealant first?
Yes, every time. New silicone does not stick to old silicone, so the joint is cleaned back first.
Why not top up the existing silicone?
A top-up rarely holds. Fresh silicone won’t bond to cured silicone so we take it all out and start clean.
How long should I leave it?
That depends on the sealant used, so please follow the time we give you.
Do you replace glass?
No, our work is the silicone. A glazier replaces glass and units.
What sealant do you use on glazing?
A neutral-cure glazing silicone that suits the glass and frame. In bathrooms, we use anti-fungal silicone.
Do you reseal glass shower screens?
Yes. We remove the old sealant and reseal the wall and tray joints.

What the job involves on each surface
Shower screens
Mouldy or lifting sealant on a screen leaks. A full reseal sorts it.
Glass balustrade bases
Glass balustrades sit in a channel that is often finished with sealant. Failed sealant there lets water collect.
Keeping the joints in good condition
After the cure time, these simple habits help:
- Clean glass with a mild cleaner and a soft cloth
- Check the silicone on glass every year or so
- Keep conservatory gutters clear of leaves
- Do not leave a drip for the next storm
Avoid scraping near the new silicone when cleaning the glass. Stick to a soft cloth.
Drips or damp near a glazing joint shouldn’t be ignored. It may be sealant, or something else, and we will tell you which.
Glazing silicone in St John's: local notes
The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you live in an older home near St John's Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame. For site and facilities teams at buildings such as The Winston Churchill School A Specialist Sports College, its window and door frames need their mastic kept sound, just like a home’s. If you let a flat or house near Woking station, a shower screen or conservatory joint that leaks is easier to reseal while the property is empty.

What affects the quote in St John's
For a quick quote, just ask. What matters most is:
- Access and height
- Working hours on commercial sites
- The amount of work
- The product the joint needs
Combining jobs into one visit usually makes better use of the time than several visits, so tell us about everything that needs sealing. We’ll send you a clear quote for the lot.
What we need to know
You don’t need to know the technical terms. It helps if you can tell us:
- If it’s domestic, commercial or a hotel
- What’s wrong with the joints now
- Any previous sealing or DIY work
- Roughly how big the job is
Every job is quoted individually, so start by telling us what you need. Just call 0345 464 0079 or send us an email with the details, and photos are welcome.
DIY sealant or a professional job?
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so just mention it when you contact us.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Landlord and commercial work in St John's
If you manage several properties in or around St John's, jobs at different addresses can be quoted together. Send us the addresses and the work at each, and pictures by email help.
We work for landlords and letting agents as well as homeowners. Resealing between tenancies keeps a property looking cared for before the next move-in.
When something else is needed
Some problems need a builder, plumber or other trade rather than us:
- A frame that needs repairing or replacing
- Leaks from the roof covering or flashing (a roofer’s job)
- Cracked or broken glass
Not sure which it is? You can call 0345 464 0079 or send us an email and we’ll tell you honestly.
Joints and surfaces we work on
- Glass-to-glass joints
- Glass balustrade bases
- Shower screens
- Conservatory frames
- Glass-to-frame joints
- Rooflights
The process
Before we leave, we go over the finished joints with you. The visit itself generally takes a few hours for most jobs, depending on how much there is to do. For a job in St John's, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- We start by finding the leak and making sure sealant is the cause.
- Old silicone is cut away from the glass and frame without scratching either.
- We clean the joint with a solvent that suits the glass and frame.
- We apply a neutral-cure glazing silicone and tool it smooth.
- The finished joints are checked and, where it’s safe, tested with water.
Preparing for the visit
- For indoor joints, keep the area dry beforehand if you can
- Mention if the joints have been sealed before
- Let us know about parking restrictions
