Kilburn Glazing Silicone
Our applicators work in Kilburn on glazing silicone for conservatories, rooflights, glass panels and shower screens. Old sealant removed completely, joints prepared properly and a one-year guarantee.
- Glazing silicone that has cracked or come away
- Water running down inside the glass
- Water escaping where a screen meets the wall
What happens on the day
You do not need to clear the whole room or building, only the area right around the joints. We protect the rest, and the work takes anything from an hour or two to most of a day, depending on the size of the job for a typical job. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Kilburn. A visitor permit or a nearby bay makes the visit run more smoothly.
- We start by finding the leak and making sure sealant is the cause.
- We cut out the failed silicone, taking care of the glass and frame.
- Surfaces are cleaned with a solvent suited to glass and the frame.
- Glazing silicone suited to the joint is applied and tooled.
- We look over every joint and, where we can, test it with water.
How to prepare
- Tell us about any water getting in
- For indoor joints, keep the area dry beforehand if you can
- Tell us about any previous sealing or DIY attempts

Advice
Glazing silicone in Kilburn, done properly
Conservatory leaks often start at a sealant joint, where glass meets frame or frame meets wall. We find the joint that is letting water in and renew it and tell you plainly if the cause is something else. Typical jobs include drips on the inside of a conservatory window and silicone pulling away from the glass, on glass-to-frame joints, glass-to-glass joints and glass balustrade bases.
London’s Victorian and Edwardian terraces were built with timber sash windows, and many still have them or their replacements. Either way, the mastic between frame and brickwork is what stops draughts and rain getting in, in Kilburn as anywhere.
A one-year guarantee comes as standard.

When it isn’t the sealant
In fairness, there are a few things sealant won’t fix:
- A broken pane or roof panel
- Misting between the panes of a double-glazed unit (a failed unit for a glazier)
- Rotten or badly damaged frames
If you are not sure, just call 0345 464 0079 or email us and we’ll give you a straight answer before booking.

For landlords and businesses
Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. We can quote for more than one property at once.
We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements.
Different surfaces, different methods
Glass balustrade bases
We reseal the joint where the glass meets the base channel. Glass fitting is a separate trade.
Glass-to-glass joints
Silicone joins glass panels in many frameless designs. We renew it with a clear or matching glazing silicone.

When to call us in Kilburn
Some conservatory leaks aren’t sealant at all: failed roof panels, slipped glazing bars and blocked gutters cause them too. That is why we trace the leak first.
If you can see any of these, it’s time to have the joints looked at:
- Failed joints on frameless glass
- Leaks from the base of a shower screen
- Mouldy sealant around glass panels
- Leaking glazing joints on a rooflight
Letting a property close to Queens Park (London) station? Then a shower screen or conservatory joint that leaks is easier to reseal while the property is empty.

Kilburn homes and the weather
Historic houses like Winfield House (about 1.7 miles east) are a reminder that the area around Kilburn has older buildings as well as new. Where a home is older, 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 Anne's and St Andrew's, frames set in older brick or stone need a sealant that suits the wall as well as the frame. As a London address, Kilburn can be tricky for parking: let us know about parking bays, permits or a driveway.

How to look after the new joints
No joint lasts for ever, but care makes a real difference. Our tips:
- Check the gutters above the glazing for debris
- Ventilate the conservatory to cut condensation
- Do not leave a drip for the next storm
- Do not use a blade near the sealant
Look over the glazing joints every year or so. Spotting a crack early means a simpler fix, before water gets in.
Don’t leave lifting or mouldy silicone on glazing. Once it starts to peel, water gets behind it and the leak gets worse.
Can I do it myself?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
