How we handle glazing silicone in Westbourne Green
Glazing silicone is a maintenance item. Weather and movement take their toll, and once it cracks, water follows. Renewing it keeps glazing joints doing their job. We work on shower screens, glass balustrade bases and glass-to-frame joints, and common reasons people get in touch are a quick top-up bead that didn’t last and water getting into a conservatory at the joints.
London’s Victorian and Edwardian terraces were built with timber sash windows, and many still have them or their replacements. Whatever is in the opening now, the joint between frame and wall is what keeps the weather out.
Our work is backed for twelve months, in Westbourne Green and everywhere else we cover.

What the job involves on each surface
Glass balustrade bases
The base of a glass balustrade is usually sealed. When it fails, water can sit in the channel.
Glass-to-glass joints
Where two panes meet, the silicone joint takes all the movement. The bead needs to be tidy and fully bonded.
Why act early in Westbourne Green
Replacing a conservatory roof is major work. If the leak is a failed sealant joint, resealing is far simpler. If it’s the roof itself, we’ll tell you. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and once it shows in Westbourne Green, the repair is bigger than a sealant job.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, plus any working-time requirements on site. Call for a quick quote and we’ll explain what it covers.

How to look after the new joints
Good habits help new joints last longer. Our tips:
- Check the silicone on glass every year or so
- Keep scrapers and blades away from the silicone
- Clear the conservatory gutters regularly
- Get a new leak looked at quickly
Gentle products are best near the sealant. Harsh solvents may damage the bead.
Cracked glazing silicone means the joint has failed. Renewing it early keeps it simple, compared with repairing damaged frames or plaster.
What affects the quote in Westbourne Green
Jobs vary more than people expect. What affects the quote:
- The number of rooms or windows
- When we can work, for business premises
- Whether the work is at height
- The number and length of the joints
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.
What to tell us for a quote
What to tell us when you ask for a quote:
- How many joints, rooms or windows are involved

Your questions about glazing silicone in Westbourne Green
Is parking an issue for glazing silicone in Westbourne Green?
In much of London, parking needs planning: a visitor permit or a bay close to the door helps a lot, so mention what’s available when you book.
I let a flat near London Paddington station. Can you help?
Yes, we work for letting agents and landlords. Just phone 0345 464 0079 or drop us an email and tell us about the property, and we will give you a clear price.
What do you need from me for a quote?
Only a few details: where it is, what you’ve noticed and how we reach it. Then phone 0345 464 0079 or drop us an email.
Is it possible to redo the silicone on a shower screen?
Yes, we do these often. The screen is resealed with anti-fungal silicone suited to bathrooms.
Can I add another job to the visit?
Yes. More than one area can go on one quote.
Do you take out the old sealant first?
Always. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
Is a special sealant needed for glass?
We pick a glazing silicone to suit the materials. Neutral-cure silicone is the usual choice.
Can you match the sealant colour?
We’ll suggest a colour to suit the surroundings. The choice depends on the product the joint needs.
What sealant work cannot fix
To be straight with you, there are a few things sealant won’t fix:
- A broken pane or roof panel
- Water coming through the roof rather than a sealant joint
- Frames that have decayed or split
If in doubt, ring 0345 464 0079 or send us an email and we’ll say what we think.

What glazing silicone looks like in Westbourne Green
With historic houses such as Kensington Palace (about 1 mile south) nearby, there’s older building stock in the area around Westbourne Green as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. In London conversions and blocks, the lease decides who is responsible for the frames, so check that before you book.
Westbourne Green is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book. Letting a property close to London Paddington station? Then a shower screen or conservatory joint that leaks is easier to reseal while the property is empty. Homes close to St Mary Magdalene include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
