Glazing silicone in Wych Cross
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. We work on conservatory frames, shower screens and glass-to-frame joints, and the jobs we see most are new silicone smeared over old sealant and conservatory leaks at frame and glazing joints.
Homes in small places like Wych Cross often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.
Each job carries a 12-month guarantee, large or small.

Glazing silicone in Wych Cross: local notes
Historic houses like Standen (about 3.2 miles north-west) are a reminder that the area around Wych Cross has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Standen, about 3.2 miles north-west, is one of the historic houses in the wider area around Wych Cross. If you look after a building such as Greenfields School, the mastic around its windows and doors needs looking after like any other building’s.

When something else is needed
New sealant can’t fix everything, and we’d rather say so up front. Sealant won’t put right:
- Cracked or broken glass
- A sagging or failing conservatory roof
- Frames that have decayed or split
If in doubt, phone 0345 464 0079 or drop us an email and we’ll say what we think.
Surfaces we seal
- Glass balustrade bases
- Shower screens
- Glass-to-frame joints
- Rooflights
- Glass-to-glass joints
- Conservatory frames
Different surfaces, different methods
Rooflights
We reseal the glazing joints on rooflights. Leaks from the roof itself need a roofer.
Glass-to-glass joints
You see these joints clearly, so we take care to leave a neat bead.
Why act early in Wych Cross
Glazing joints need a sealant made for the job. A general-purpose tube may not bond well or may react with the frame so we choose a glazing silicone instead. Older cottages and farmhouses around Wych Cross can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
What it costs depends on the size of the job, how hard the old material is to remove and access to the work. We give a clear quote before work begins.

Your questions about glazing silicone in Wych Cross
Do you cover Wych Cross for glazing silicone?
Yes, Wych Cross is within the area we cover. Our work covers London and the South East. Just phone 0345 464 0079 or drop us an email with a few details of the job.
I let a flat near East Grinstead station. Can you help?
Yes, rental work is part of what we do. You can ring 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before work begins.
Is it worth trying it myself?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
Does someone need to be in?
That depends on where the joints are. Inside work needs someone to give us access, and for outside work we will agree access with you when we book.
What do you put in the joint?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
Are you fully insured?
Yes. We’re fully insured.
Do you offer different sealant colours?
Usually, yes. Sealants come in white, clear, grey and other colours, and we will agree it with you first.
Will there be a smell?
It depends on the product. Some smell for a while, some hardly at all, and any smell fades as they cure.
How it works
We keep the work tidy and contained to the joints we’re treating. Expect the work to take a few hours for most jobs, and we explain the cure time before we leave. Somewhere like Wych Cross needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- We trace the leak and confirm it’s a sealant joint.
- We remove the old sealant carefully.
- The joint is cleaned and degreased.

How to look after the new joints
Good habits help new joints last longer. Our tips:
- Act on drips or damp patches early
- Clear the conservatory gutters regularly
- Clean glass with a mild cleaner and a soft cloth
- Avoid scraping close to the bead
Gentle products are best near the sealant. Strong solvents can soften or mark it.
Cracked glazing silicone means the joint has failed. Renewing it early keeps it simple compared with fixing water damage later.
What we’re called out for in Wych Cross
Dirt and grease stop silicone sticking. Where the joint wasn’t cleaned and degreased the sealant may lift within a few years.
People normally contact us after spotting one of these:
- Sealant that was laid over old silicone and failed
- Shower screens leaking along the wall or tray
- Drips on the inside of a conservatory window
- Mouldy sealant around glass panels
If you let a flat or house near East Grinstead station, a shower screen or conservatory joint that leaks is easier to reseal while the property is empty.
What your quote should include
- What the cure time is
- What product goes in the joint
- The length of the guarantee
- Who does the work, and how experienced they are
