Glazing silicone in Kenton, done properly
Glazing silicone that has yellowed, blackened or come away spoils the look and lets water in. We remove it without scratching the glass or frame and reseal the joint. If you have cracked silicone between glass panels and rooflight joints letting water in, we can help, whatever the surface.
From mansion-block windows to modern glazing in new flats, London has every kind of frame. Over the years, the sealant around them shrinks, cracks and pulls away, which is when draughts and damp patches appear in homes in Kenton.
Big or small, it’s backed by our one-year guarantee in Kenton and across Greater London.

Kenton: your questions answered
Is Kenton in your area for glazing silicone?
Yes, Kenton is within the area we cover. Our work covers London and the South East. You can ring 0345 464 0079 or send us an email and tell us what needs doing.
Is parking an issue for glazing silicone in Kenton?
London parking needs a little planning, so let us know about permits, bays or a driveway when you book. The visit is then planned around what’s available.
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.
How long will you be here?
It depends on the size of the job, but as a guide it takes a few hours, depending on how many joints need doing. We will tell you when we quote.
Do you do commercial work?
Yes. Commercial and hotel work is a large part of what we do. Working times can be discussed when we quote.
Do you seal glass balustrade bases?
Yes, where the base is finished with sealant. Send us photos and we’ll take a look when you call 0345 464 0079 or drop us an email.
What sealant do you use on glazing?
We pick a glazing silicone to suit the materials. Neutral-cure products suit most glass and frames.
What does glazing silicone cost?
It depends on the job, so we quote each one individually. For a quick quote, call 0345 464 0079 or email us and tell us what needs doing and where.
DIY sealant or a professional job?
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
If you are set on DIY, put the effort into 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.
Quotes for glazing silicone in Kenton
You will get a clear quote before any work starts. It takes into account:
- Working hours on commercial sites
- The product the joint needs
- How easy the joints are to reach
- The number and length of the joints
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference.
What to tell us for a quote
Photos help, but a description is a good start. Please mention:
- What the problem is, such as mould, gaps, leaks or cracking
- Where the property is
- The type of property
- Pictures of the joints, sent by email
Call for a quick quote, or email us if that’s easier. Describe what needs sealing and we’ll talk you through the work before giving you a price.
Looking after it afterwards
To keep the joints looking good and working properly:
- Don’t leave a drip for the next storm
- Check the silicone on glass every year or so
- Open vents or windows to let moisture out
- Keep scrapers and blades away from the silicone
Keep the new joints dry for as long as we advise. From then on, a mild glass cleaner is all it needs.
Act on black or lifting silicone early. Peeling silicone lets water in behind and the problem grows.

- Surfaces are cleaned with a solvent suited to glass and the frame.

Honest advice matters more to us than a booking, so here’s what new sealant will not do:
- A broken pane or roof panel
