How we handle glazing silicone in East Finchley
Not every silicone suits glass. We use a neutral-cure glazing silicone that is suited to glass and the frame, finished with a neat, even bead. If you are dealing with water tracking down the inner face of the glass and glass-to-glass joints that have split, we can help.
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 East Finchley as anywhere.
Our work is backed for twelve months.

Signs you need glazing silicone in East Finchley
Dirt and grease stop silicone sticking. If the glass and frame weren’t cleaned properly, the bead can peel away early.
Keep an eye out for these signs:
- Silicone pulling away from the glass
- A quick top-up bead that didn’t last
- Leaks from the base of a shower screen
- Leaks where conservatory glass meets the frame

East Finchley homes and the weather
With historic houses such as Heath Hall (about 1.1 miles south) nearby, there’s older building stock in the area around East Finchley as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
East Finchley is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book. If you look after a building such as Holy Trinity CofE Primary School, its window and door frames need their mastic kept sound, just like a home’s.

Your questions about glazing silicone in East Finchley
Can you do glazing silicone in East Finchley?
Yes, East Finchley 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, and we’ll send you a clear quote.
Can you help a landlord with a rental near New Southgate station?
Yes. We work for letting agents and landlords as well as homeowners, and several properties can go on one quote. You can phone 0345 464 0079 or drop us an email with the details for a clear quote.
Can you quote for more than one area?
Yes. Several rooms, windows or areas can go on one quote.
Do you remove the old sealant?
Yes. We cut out all the old sealant and clean the joint.
Can you replace a misted double-glazed unit?
No. A misted unit has failed inside, and a glazier needs to replace it.
Do I need to be at home?
If the work is inside, we need someone to let us in. After that, you can carry on with your day.
Can I choose the sealant colour?
Generally, yes. Sealants come in white, clear, grey and other colours for many products, and we agree the colour with you before work begins.
When is the sealant fully cured?
Most sealants are touch-dry well before they’re fully cured. We will tell you how long to leave the joint.
DIY sealant or a professional job?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
Why act early in East Finchley
You do not need new glazing because the sealant has gone. If the glass and frame are sound, new silicone is often all it takes. In London conversions, one flat’s bathroom is often above another flat’s ceiling, and a slow leak from a failed seal can end up in the flat below. Putting it right early is much less trouble for homes in East Finchley.

What affects the quote in East Finchley
Call for a quick quote. The main things that affect it are:
- Access and height
- How much old sealant there is and how hard it is to remove
- The number of rooms or windows
- Whether there’s mould to deal with
Doing several joints on one visit normally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. We’ll give you a clear price for the lot.

What we do, step by step
On the day, we look over the joints with you first, so there are no surprises. We protect the surfaces around the joints before any work begins. The work usually takes a few hours for most jobs. In East Finchley, as in most of London, parking needs a little planning. A visitor permit or a nearby bay makes the visit run more smoothly.
- We trace the leak and confirm it’s a sealant joint.
- The failed silicone is cut out without marking the glass or frame.
- The joint is cleaned and degreased.
- We lay the new bead and tool it smooth.
- Each joint is checked and, where possible, water-tested.
Before we arrive
- Let us know about earlier repairs to the joints
- Tell us about access, such as stairs, a lift or high-level joints
- For business premises, tell us about site rules or sign-in

How to look after the new joints
How long the joints last depends on use and care. We suggest:
- Keep air moving in the conservatory
- Keep conservatory gutters clear of leaves
- Act on drips or damp patches early
- Keep harsh solvents off the silicone
Check the joints once a year. Spotting a crack early means a simpler fix.
Act on black or lifting silicone early. Peeling silicone lets water in behind and the problem grows.
