Glazing silicone in Brent Cross
We renew glazing silicone on conservatories, rooflights and glass panels plus shower screens and the bases of glass balustrades. The old sealant comes out, the joint is cleaned and new silicone goes in. Typical jobs include failed joints on frameless glass and sealant that was laid over old silicone and failed, across shower screens, glass-to-glass joints and rooflights.
London homes have every kind of window, from timber sashes in period terraces to aluminium and uPVC in newer blocks. Over the years, the sealant around them shrinks, cracks and pulls away, which is when draughts and damp patches appear in homes in Brent Cross.
Your job is guaranteed for a year, as with all our work.

When to call us in Brent Cross
Silicone will not bond to a dirty surface. If the glass and frame weren’t cleaned properly the sealant may lift within a few years.
It’s worth asking for a quote if you see:
- Split or lifting silicone on glass
- Mouldy sealant around glass panels
- Leaks where conservatory glass meets the frame
- Shower screens leaking along the wall or tray
Homes close to Christ Church Hendon include some older properties, and the joint between an old wall and a newer frame is generally the first place rain gets in.

Why it’s worth doing now in Brent Cross
A new conservatory roof is a big job. Where the water is getting in through sealant, resealing is far simpler. If the roof is the problem, we’ll say so. Converted houses in London often have a bathroom above someone else’s living room, and a slow leak from a failed seal can end up in the flat below. Dealing with it early is far simpler.
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part.

Brent Cross: your questions answered
Is parking an issue for glazing silicone in Brent Cross?
Parking in Brent Cross, 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.
Can you do glazing silicone in Brent Cross?
Yes. We work across London and the South East, and Brent Cross is part of that. You can ring 0345 464 0079 or drop us an email and let us know what needs doing.
Do you do commercial work?
Yes. We work in offices, washrooms, hotels and other commercial premises, as well as homes. Working times can be discussed when we quote.
Should I try DIY first?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Will the old sealant be removed?
Always. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Do I need to be at home?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
I rent my home. Can I book you?
Yes. Check with your landlord; we can send the quote to them too.
What does glazing silicone cost?
Size, access and the old material all affect the cost. Call for a quick quote and we’ll talk you through it.

- We cut away the failed silicone.
- The surfaces are cleaned with a suitable solvent.
- New glazing silicone goes in and is finished neatly.
- The joints are checked before we leave.

How to look after the new joints
To keep the joints looking good and working properly:
- Look over the glazing joints once a year
- Act on drips or damp patches early
- Keep harsh solvents off the silicone
- Don’t use a blade near the sealant
Look over the glazing joints every year or so. Catching a split early keeps the repair small, before water gets in.
Cracked glazing silicone means the joint has failed. Renewing it early keeps it simple compared with fixing water damage later.
What the job involves on each surface
Glass-to-frame joints
Old sealant is removed carefully from the glass and reseal with glazing silicone.
Shower screens
Silicone holds the water in on frameless screens. We renew it without marking the glass.
