How we handle glazing silicone in West Hendon
Across West Hendon, we reseal glazing joints in homes, offices and hotels. Conservatories, rooflights, glass panels and shower screens are all part of the job, with a sealant chosen for the joint. If you’re dealing with leaks where conservatory glass meets the frame and leaking glazing joints on a rooflight, we can help.
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 West Hendon.
There’s a 12-month guarantee on every job, whatever its size.

Your questions about glazing silicone in West Hendon
Is parking a problem for a job in West Hendon?
It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. The visit is then planned around what’s available.
I let a flat near Hendon station. Can you help?
Yes, we work for letting agents and landlords. Just ring 0345 464 0079 or send us an email and tell us about the property, and we’ll give you a clear quote.
How do I get a quote for glazing silicone in West Hendon?
There’s no set price, as it depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
Do you cover West Hendon?
Yes. From our base in Crawley, we cover South East England, London and all of Scotland.
What sealant do you use on glazing?
Glass needs a sealant made for glazing. We use neutral-cure glazing silicone and anti-fungal silicone in wet areas.
Which products do you use?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice, and we’ll tell you what we are using.
Can you replace a misted double-glazed unit?
That’s not something we do. Misting between panes means the sealed unit has failed and needs replacing by a glazier.
Can you quote for more than one area?
Yes, and it often makes sense. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
The process
Once we are on site, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours for most jobs. For a job in West Hendon, parking and access are the things to plan: let us know about parking, the floor we will be working on and any lift or shared entrance.
- First, we check where the water gets in.
- We remove the old sealant carefully.
- The joint is cleaned and degreased.
- A neutral-cure glazing silicone is applied and tooled.
- Each joint is checked and, where possible, water-tested.
Before we arrive
- Tell us if parking is tricky
- Keep children and pets away from the work area
- Mention if the joints have been sealed before

We reseal the joint where the glass meets the base channel. Glass fitting is a separate trade.

How we quote for glazing silicone
Your quote is based on your job. We look at:
- Access and height
- The old material and how stubborn it is
- Mould in or behind the old joints
- How many areas need sealing
Combining jobs into one visit usually makes better use of the time than several visits. You will get one clear quote for the whole job.
What to tell us for a quote
Photos help, but a description is a good start. Please mention:
- Where the job is, and your postcode
- A few pictures by email, if you can
- How many joints, rooms or windows are involved
- What the problem is, such as mould, gaps, leaks or cracking
For a quote, phone 0345 464 0079 or email us and tell us where the job is and what the problem looks like. We will send you a clear quote before any work starts.
Aftercare tips
How long the joints last depends on use and care. Here’s what we suggest:
- Inspect the sealant on glazing annually
- Stick to mild cleaners on glass
- Run a squeegee over the glass when you are done
- Act on drips or damp patches early
Use mild cleaners on and around the silicone. Strong solvents can soften or mark it.
Conservatory leaks rarely stay small. Water runs along frames and down walls so it’s best dealt with right away.

What happens if it’s left?
Topping up old silicone can look like a fix, but new silicone will not bond to old and water soon finds its way back. A proper reseal is the lasting answer. Damp from a failed joint spreads quietly in older London brickwork and timber, and by the time it shows on a wall or ceiling in West Hendon, the repair is bigger than the sealant job would have been.
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.

West Hendon homes and the weather
With historic houses such as Heath House (about 3.2 miles south-east) nearby, there’s older building stock in the area around West Hendon 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’s traditional sand mastic. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
As a London address, West Hendon can be tricky for parking: tell us about permits, visitor bays or off-street space when you book. For an older house near a landmark such as St Matthias the Apostle church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. Schools such as The Hyde School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.
