Glazing & conservatory sealant in Fitzrovia, Greater London
Specialist glazing silicone for Fitzrovia: the right sealant, proper preparation and a neat finish. Call for a quick quote.
- Water getting into a conservatory at the joints
- Leaking glazing joints on a rooflight
- Failed joints on frameless glass
Keeping the joints in good condition
Looking after new joints is easy, and it makes a real difference:
- Use gentle products around the joints
- Look over the glazing joints once a year
- Don’t leave a drip for the next storm
- Keep scrapers and blades away from the silicone
Squeegee a shower screen after each shower and keep the room ventilated. It helps stop mould getting into the silicone.
Act on black or lifting silicone early. Once it starts to peel, water gets behind it and the problem grows.
How we handle glazing silicone in Fitzrovia
Conservatory leaks often start at a sealant joint, where glass meets frame or frame meets wall. We trace the leak to the joint and reseal it, and if it’s something sealant cannot fix, we’ll tell you. We work on glass balustrade bases, glass-to-frame joints and glass-to-glass joints, and the jobs we see most are failed sealant around rooflight glass and shower screens leaking along the wall or tray.
Much of London’s older housing was built with timber sash windows, some still in place and some long since replaced. Either way, the mastic between frame and brickwork is what stops draughts and rain getting in, in Fitzrovia as anywhere.
Whatever the size of the job, you get the same one-year guarantee in Fitzrovia and across Greater London.

Different surfaces, different methods
Glass balustrade bases
We reseal the joint where the glass meets the base channel. We do not install or replace glass.
Conservatory frames
The joints where the conservatory meets the house take a lot of movement. We reseal them with a sealant suited to the frame.
Leave it or put it right?
Resealing can’t fix a failed unit or a cracked panel. We’ll tell you that rather than seal it anyway and point you to a glazier or roofer. 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. Dealing with it early is far simpler.
A failed joint rarely gets cheaper to fix by waiting. If you are not sure whether it needs doing, phone 0345 464 0079 or send us an email and we will give you an honest view and a quote.

Fitzrovia homes and the weather
With historic houses such as Handel Hendrix House (about 0.8 miles south-west) nearby, there’s older building stock in the area around Fitzrovia as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For site and facilities teams at buildings such as All Souls CofE Primary School, its window and door frames need their mastic kept sound, just like a home’s. For landlords with property near London Euston station, a shower screen or conservatory joint that leaks is easier to reseal while the property is empty.

What we’re called out for in Fitzrovia
Dirt and grease stop silicone sticking. Where the joint wasn’t cleaned and degreased the sealant may lift within a few years.
If you can see any of these, it’s time to have the joints looked at:
- Leaks where conservatory glass meets the frame
- Rooflight joints letting water in
- Drips on the inside of a conservatory window
- Cracked silicone between glass panels
As a London address, Fitzrovia can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.
What your quote should include
- How the surfaces are prepared before sealing
- Whether the sealant suits the joint
- How much experience the applicator has
- Whether all the old sealant comes out first
What affects the cost of glazing silicone
The price is agreed before any work begins. It’s based on:
- Whether the work is at height
- Which sealant suits the joint
- How many rooms, windows or areas are involved
- Any working-time requirements on site
Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all make a difference.

Fitzrovia: your questions answered
Is parking a problem for a job in Fitzrovia?
Parking in Fitzrovia, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day run more smoothly.
Do you cover Fitzrovia for glazing silicone?
Yes, Fitzrovia is within the area we cover. Our work covers London and the South East. You can phone 0345 464 0079 or drop us an email and tell us what needs doing.
Is balustrade sealant something you do?
We can, if the base joint is sealed. Photos help us see what’s there when you call 0345 464 0079 or send us an email.
Do I need to be at home?
That depends on where the joints are. For work indoors, someone needs to let us in, and for outside work we’ll agree access with you when we book.
Will the old sealant be removed?
Yes, every time. New sealant won’t bond properly to old, so the joint is cleaned back first.
Is it messy?
We keep the work tidy. Nearby surfaces are protected, and the area is left clean when we finish.
Where do you work from?
We’re a Crawley-based firm, with over 20 years’ experience. We work across South East England, London and Scotland.
Why not top up the existing silicone?
It doesn’t last. Fresh silicone won’t bond to cured silicone, so we remove the old sealant and clean the joint.
