How we handle glazing silicone in Edgware Bury
Glass replacement is not something we do, and misting between panes means a failed sealed unit. Our work is the sealant joints and that’s often where the water gets in. We’re often asked to deal with failed joints on frameless glass and a quick top-up bead that didn’t last, across glass balustrade bases, conservatory frames and rooflights.
Many London homes are flats, with windows high above the street. Who looks after the outside of the frames can depend on the lease, so check that first.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

The process
On the day, we look over the joints with you first. Surfaces next to the work are protected before we start. Most jobs take a few hours for most jobs. In Edgware Bury, as in most of London, parking needs a little planning. A visitor permit or a nearby bay makes the visit run more smoothly.
- We find where water is getting in and check whether it’s a sealant joint.
- We cut out the failed silicone, taking care of the glass and frame.
- The glass and frame are cleaned and degreased.
- We apply a neutral-cure glazing silicone and tool it smooth.
- We look over every joint and, where we can, test it with water.
Getting ready for the visit
- Clear the area around the work
- Let us know about parking restrictions
- Mention any tricky access

What else we do in Edgware Bury
What glazing silicone looks like in Edgware Bury
Historic houses like Headstone Manor (about 4.1 miles south-west) are a reminder that the area around Edgware Bury has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. In a converted house or block, who looks after the windows depends on the lease, so check that before booking.
In the older streets around St Andrew, frames set in older brick or stone need a sealant that suits the wall as well as the frame. If you let a flat or house near Elstree & Borehamwood station, glazing joints are worth checking at the end of a tenancy, before a small leak grows.

Your questions about glazing silicone in Edgware Bury
I let a flat near Elstree & Borehamwood station. Can you help?
Yes, we work for landlords and agents. Just phone 0345 464 0079 or drop us an email and tell us about the property, and we will send you a clear quote.
Is parking a problem for a job in Edgware Bury?
London parking needs a little planning, so let us know about permits, bays or a driveway when you book. That way the visit can be planned around it.
Do you cover Edgware Bury?
Yes. We’re based in Crawley and work across South East England, London and Scotland.
How much does glazing silicone cost in Edgware Bury?
We don’t publish prices, because the cost 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.
Should I try DIY first?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Will the old sealant be removed?
Yes, always, and completely. New silicone doesn’t stick to old silicone, so any old material comes out before anything new goes in.
How long does glazing silicone take?
Typically it takes anything from an hour or two to most of a day, depending on the size of the job. Bigger jobs take longer, and we’ll tell you how long to expect.
Do you seal glass balustrade bases?
Yes, we reseal the joint at the base channel. We don’t install or replace the glass.
When to call us in Edgware Bury
The wrong sealant is a common cause. Some products don’t bond well to glass, and acetoxy types can attack some frame materials.
Keep an eye out for any of the following:
- Leaks where conservatory glass meets the frame
- Drips on the inside of a conservatory window
- A quick top-up bead that didn’t last
- Rooflight joints letting water in
If you look after a building such as Broadfields Primary School, the mastic around its windows and doors needs looking after like any other building’s.
Questions to ask before you book
- Whether VAT is included
- How hidden problems are handled
- Whether they’re fully insured
- What product goes in the joint
Keeping the joints in good condition
Aftercare is simple:
- Look over the glazing joints once a year
- Use a gentle glass cleaner and a soft cloth
- Check the gutters above the glazing for debris
- Act on drips or damp patches early
On shower screens, wipe or squeegee after use and let the room air. It helps stop mould getting into the silicone.
Drips or damp near a glazing joint shouldn’t be ignored. It may be sealant, or something else and we’ll find out which.
Quotes for glazing silicone in Edgware Bury
You’ll get a clear quote before any work starts. It’s based on:
- How many rooms, windows or areas are involved
- Which sealant suits the joint
- Whether there’s mould to deal with
- The old material and how stubborn it is
We don’t show prices on the website, because each job is priced on what it involves. For a quick quote, please call 0345 464 0079 or drop us an email.
What to tell us for a quote
The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:
- Access, such as stairs, a lift or height
- Whether it has been sealed before
- How many joints, rooms or windows are involved
- What’s wrong with the joints now
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints.
Should I try it myself first?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
Why it’s worth doing now in Edgware Bury
Dealing with a leaking shower screen early protects the floor and ceiling. Water from a failed joint can soak into the floor before it shows. In a London flat, a failed joint rarely stays your problem alone: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
What you pay reflects the work, not guesswork. That is why we ask about the job first and agree the price before starting.

We reseal the glazing joints on rooflights. Leaks from the roof itself need a roofer.
Conservatory frames
The joints where the conservatory meets the house take a lot of movement. We reseal them with a sealant suited to the frame.
