Willesden questions
Is parking an issue for glazing silicone in Willesden?
London parking needs a little planning, so let us know about permits, bays or a driveway when you book. The visit is then planned around what’s available.
Do you work for landlords with property near Kensal Rise station?
Yes. We work for landlords and letting agents as well as householders, and several properties can be quoted together. You can ring 0345 464 0079 or send us an email with the details for a clear quote.
Can you match the sealant colour?
In most cases you can choose. We’ll tell you which colours the right product comes in and agree one before work begins.
Do you work in Willesden?
We do. Our applicators work in Willesden, and the service is the same as everywhere else.
Do you have insurance?
Yes. We’re fully insured.
Do you replace glass?
No. Misting between panes means the sealed unit has failed and needs replacing by a glazier.
How long does glazing silicone take?
A typical job takes a few hours, depending on how many joints need doing, including the preparation. Your quote will say how long we expect yours to take.
Will resealing stop my conservatory leaking?
It depends on the cause. Sealant joints we can renew but roof and panel problems need another trade.
Glazing silicone in Willesden, done properly
Frameless shower screens rely on sealant to keep water in. Leaks normally come from the wall joint or the tray joint and both get fresh anti-fungal silicone. Common call-outs are for split or lifting silicone on glass and conservatory leaks at frame and glazing joints, on shower screens, glass-to-frame joints and glass balustrade bases.
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, letting in draughts and water.
Each job carries a 12-month guarantee, whatever its size.

Do you need glazing silicone in Willesden?
Sealant laid over old sealant doesn’t last. Many failed joints we see have been topped up rather than cut out, and water gets between the layers.
Most people get in touch when they notice something like this:
- Shower screens leaking along the wall or tray
- Rooflight joints letting water in
- Split or lifting silicone on glass
- Water tracking down the inner face of the glass
For landlords with property near Kensal Rise station, a shower screen or conservatory joint that leaks is easier to reseal while the property is empty.

Frames and glazing around Willesden
London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Fenton House (about 2.5 miles east) are a reminder that the area around Willesden 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.
Willesden is in London, so parking needs planning: let us know about parking bays, permits or a driveway. In the older streets around Church of St Andrew, the joint between an old wall and a newer frame is generally the first place rain gets in.

Surface by surface
Rooflights
A rooflight faces rain and sun from above. The sealant around the glass and frame wears faster than most.
Glass-to-frame joints
The sealant must stick to glass and frame alike. We use a glazing silicone suited to each.
Leave it or put it right?
Glazing joints need a sealant made for the job. General-purpose sealant from a DIY shop may not suit glass or the frame so we choose a glazing silicone instead. 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.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you’re not sure whether it needs doing, phone 0345 464 0079 or send us an email for an honest opinion and a quote.

Aftercare tips
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Wipe the screen down after showering
- Keep harsh solvents off the silicone
- Avoid scraping close to the bead
- Clear the conservatory gutters regularly
Do not use blades or scrapers near the bead when you clean. A soft cloth or sponge is best.
Damp patches, drips and condensation along a joint are worth checking. It may be sealant, or something else and we’ll find out which.
How it works
There’s no need to move everything out, only the area right around the joints. We protect the rest, and the job takes anything from an hour or two to most of a day, depending on the size of the job in most cases. For a job in Willesden, parking and access are the things to plan: let us know about parking, the floor we’ll be working on and any lift or shared entrance.
- First, we check where the water gets in.
- The failed silicone is cut out without marking the glass or frame.
- The joint is cleaned and degreased.
- A neutral-cure glazing silicone is applied and tooled.
- We check the finished joints and test with water where it’s safe.
Before we arrive
- Tell us if parking is tricky
- Tell us about access, such as stairs, a lift or high-level joints
- Keep children and pets away from the work area
