Kingsbury questions
Do you cover Kingsbury for glazing silicone?
Yes. Our work covers London and the South East, and Kingsbury is part of that. You can ring 0345 464 0079 or email us and let us know what needs doing.
Do you work for landlords with property near Hendon station?
Yes, we work for letting agents and landlords. You can call 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before work begins.
What should I tell you?
A short description and the location, plus pictures if you have them. If we need more, we’ll ask.
How long should I leave it?
Cure times vary by product and the temperature. Before we leave, we’ll tell you the cure time.
How do I get a quote for glazing silicone in Kingsbury?
It depends on the job, so we quote each one individually. To get one, phone 0345 464 0079 or drop us an email and tell us what needs doing and where.
Do you take out the old sealant first?
Always. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
Which silicone is used for glass joints?
We use a neutral-cure glazing silicone suited to glass and the frame. In bathrooms, we use anti-fungal silicone.
Can a conservatory leak be sealed?
In many cases, as long as sealant is the cause. We trace the leak first before any sealing.
Glazing silicone in Kingsbury
Frameless shower screens rely on sealant to keep water in. The joint down the wall and the one along the tray are common leak points, and we reseal both. If you have water getting into a conservatory at the joints and rooflight joints letting water in, we can put it right, on glass balustrade bases, conservatory frames and shower screens alike.
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 Kingsbury.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we’ll put it right.

Landlords, agents and businesses in Kingsbury
Housing providers, facilities teams and property managers book us too in Kingsbury and across Greater London. Several sites can go on one quote.
Letting agents often deal with us directly. Tell us the address, the job and how access works and we will quote.
How we quote for glazing silicone
You will get a clear quote before any work starts. It’s based on:
- Any working-time requirements on site
- How many rooms, windows or areas are involved
- The type of sealant required
- Access and height
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part, and we’ll explain the quote if you ask.
What to tell us for a quote
To help us quote quickly, let us know:
- How many joints, rooms or windows are involved
- If it’s domestic, commercial or a hotel
- Where the property is
- Any access issues, like height or stairs
Quotes start with a quick conversation. Tell us what’s wrong, where it is and how much there is, and we will explain how we’d tackle it. Whenever you’re ready, phone 0345 464 0079 or email us.
What sealant work cannot fix
We’ll always be straight with you, so here’s what new sealant will not do:
- Frames that have decayed or split
- Misting between the panes of a double-glazed unit (a failed unit for a glazier)
- Leaks from the roof covering or flashing (a roofer’s job)
If in doubt, call 0345 464 0079 or send us an email and we will say what we think before booking.

What we’re called out for in Kingsbury
Sunlight breaks sealant down and roof joints get the most sun. Old silicone hardens, cracks and loses its grip on the glass.
Look out for these signs:
- Leaks from the base of a shower screen
- Mouldy sealant around glass panels
- Leaks where conservatory glass meets the frame
- Drips on the inside of a conservatory window
For site and facilities teams at buildings such as Kingsbury Green Primary School, its window and door frames need their mastic kept sound, just like a home’s.

Windows and doors in Kingsbury
Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Headstone Manor (about 3.5 miles west) are a reminder that the area around Kingsbury has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
Kingsbury is in London, so parking needs planning: let us know about parking bays, permits or a driveway. For landlords with property near Hendon station, leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies.

What we do, step by step
On the day, we start by going over the job with you, so there are no surprises. Surfaces next to the work are protected before we start. Most jobs take a few hours for most jobs. In a London area like Kingsbury, the main things to plan are parking and access: tell us about permits, visitor bays or off-street space, which floor we’re working on and whether there’s a lift.
- We start by finding the leak and making sure sealant is the cause.
- Old silicone is cut away from the glass and frame without scratching either.
- Surfaces are cleaned with a solvent suited to glass and the frame.
- We apply a neutral-cure glazing silicone and tool it smooth.
- We check the joints and, where safe, run water over them.
How to prepare
- For business premises, tell us about site rules or sign-in
- Let us know about earlier repairs to the joints
- Plan for the work area to be out of bounds to pets and children

Looking after it afterwards
To keep the joints looking good and working properly:
- Look over the glazing joints once a year
- Clear the conservatory gutters regularly
- Keep harsh solvents off the silicone
- Wipe the screen down after showering
Keep the new joints dry for as long as we advise. After that, clean glass with a mild cleaner.
Act on black or lifting silicone early. Once it starts to peel, water gets behind it and the problem grows.
Can I do it myself?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly.
