Glazing Silicone in City of Westminster
Glazing silicone for conservatories, rooflights, glass panels and shower screens for householders, landlords and businesses in City of Westminster. Fully insured, ARBOMaster approved and guaranteed for a year.
- Failed sealant around rooflight glass
- Split or lifting silicone on glass
- A quick top-up bead that didn’t last
Aftercare tips
To keep the joints looking good and working properly:
- Inspect the sealant on glazing annually
- Squeegee the shower screen after each use
- Use gentle products around the joints
- Get a new leak looked at quickly
Don’t use blades or scrapers near the bead when you clean. A soft cloth or sponge is best.
If silicone on glass has cracked, water is already getting in. Resealing now is a small job compared with fixing water damage later.
Glazing silicone for homes and businesses in City of Westminster
We don’t replace glass, and misting between panes means a failed sealed unit. Our work is the sealant joints and that’s often where the water gets in. If you have sealant that was laid over old silicone and failed and mouldy sealant around glass panels, we can put it right, whatever the surface.
London homes have every kind of window, from timber sashes in period terraces to aluminium and uPVC in newer blocks. The mastic around them dries out and cracks with age, letting in draughts and water.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

Questions from City of Westminster
Is parking an issue for glazing silicone in City of Westminster?
Parking in City of Westminster, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day run more smoothly, so mention what’s available when you book.
Do you work for landlords with property near Bond Street station?
Yes, landlords and agents are among the people we work for. Just phone 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll send you a clear quote.
Can you match the sealant colour?
Yes. White, clear and grey are common, and other colours are available for many products, and we agree the colour with you before work begins.
Can you reseal a frameless shower screen?
Yes, it’s a common job. We use anti-fungal silicone made for wet areas.
Are you insured?
Yes. Full insurance covers our work, and we can confirm the details when we quote.
How long will you be here?
As a guide, most jobs take anything from an hour or two to most of a day, depending on the size of the job. Bigger jobs take longer.
Is balustrade sealant something you do?
We can. The old sealant is removed and the joint resealed using a sealant that suits the materials.
Do you replace glass?
No. A misted unit has failed inside and needs replacing by a glazier.
Signs you need glazing silicone in City of Westminster
On shower screens, constant water and cleaning products wear silicone. Mould grows into the bead and the joint starts to lift.
The most common problems we see are:
- Split or lifting silicone on glass
- Drips on the inside of a conservatory window
- Sealant that was laid over old silicone and failed
- Failed joints on frameless glass
City of Westminster is in London, so parking needs planning: let us know about parking bays, permits or a driveway.
What your quote should include
- Whether they seal over old material or remove it
- Whether they’re fully insured
- What product goes in the joint
- Who turns up on the day

Frames and glazing around City of Westminster
In a converted house or block, who looks after the windows depends on the lease, so it’s worth checking before booking. Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Letting a property close to Bond Street station? Then leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies. If you live in an older home near St Mark's, the joint between an old wall and a newer frame is normally the first place rain gets in.

Leave it or put it right?
Topping up old silicone can look like a fix, but new silicone won’t bond to old and water soon finds its way back. Cutting out and resealing properly lasts. Converted houses in London often have a bathroom above someone else’s living room, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Putting it right early is much less trouble.
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.

- Leaks from the roof covering or flashing (a roofer’s job)
