Glazing silicone for homes and businesses in Willesden Green
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 both get fresh anti-fungal silicone. Common call-outs are for glass-to-glass joints that have split and water escaping where a screen meets the wall, across conservatory frames, glass-to-frame joints and shower screens.
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.

How to look after the new joints
Good habits help new joints last longer. A few tips:
- Avoid scraping close to the bead
- Check the gutters above the glazing for debris
- Avoid strong solvents on or near the sealant
- Get a new leak looked at quickly
Keep the new joints dry for as long as we advise so the silicone can set properly. After that, clean glass with a mild cleaner.
A small conservatory leak soon spreads. Water travels along the frame and into the wall so it’s best dealt with right away.
The process
There isn’t much for you to do on the day. Show us the job and we’ll take it from there. The job generally takes anything from an hour or two to most of a day, depending on the size of the job from start to finish. In a London area like Willesden Green, the main things to plan are parking and access: tell us about permits, visitor bays or off-street space, which floor we are working on and whether there’s a lift.
- First we agree the joints to be done.
- We cut away the failed silicone.
- The surfaces are cleaned with a suitable solvent.
- New glazing silicone goes in and is finished neatly.
- We inspect the work and test it where we can.
How to prepare
- Try not to wet indoor joints just before the visit
- Clear the area around the work
- Mention if the joints have been sealed before

What glazing silicone looks like in Willesden Green
Compared with the north and west, the South East gets less rain, 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 north-east) are a reminder that the area around Willesden Green has older buildings as well as new. 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.
If you look after a building such as Donnington Primary School, its window and door frames need their mastic kept sound, just like a home’s. As a London address, Willesden Green can be tricky for parking: let us know about parking bays, permits or a driveway.

Leave it or put it right?
Fixing a leaking screen early protects what’s underneath. 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.
Combining jobs into one visit is generally more efficient than separate visits, so tell us about everything that needs sealing. We will give you a clear price for the lot.

What affects the quote in Willesden Green
Every job gets its own quote. This is what makes a difference:
- Whether the work is at height
- Which sealant suits the joint
- The size of the job
- The old material and how stubborn it is
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.
What we need to know
There’s no need for technical detail. Just tell us:
- Roughly how big the job is
- Access, such as stairs, a lift or height
- Where the job is, and your postcode
- Whether it has been sealed before
Quotes start with a quick conversation. Describe the problem, the location and the size of the job, and we will explain how we’d tackle it. Whenever you’re ready, ring 0345 464 0079 or drop us an email.
Surface by surface
Glass-to-frame joints
Silicone at the glass edge seals it into the frame. A failed bead lets water in.
Rooflights
We reseal the glazing joints on rooflights. If the leak is from the roof around it, a roofer needs to look.
Willesden Green: your questions answered
Can parking be tricky for a visit in Willesden Green?
Parking in Willesden Green, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day run more smoothly, so mention what’s available when you book.

Yes, rental work is part of what we do. Just phone 0345 464 0079 or send us an email and tell us about the property, and we’ll send you a clear quote.

What else we do in Willesden Green
Do you need glazing silicone in Willesden Green?
New silicone over old silicone won’t bond. Many failed joints we see have been topped up rather than cut out leaving a path for water.
The problems people usually mention when they call are:
- Conservatory leaks at frame and glazing joints
- Water running down inside the glass
- Mouldy sealant around glass panels
- Water escaping where a screen meets the wall
For landlords with property near Kensal Rise station, glazing joints are worth checking at the end of a tenancy, before a small leak grows.
What to look for in a quote
- Who turns up on the day
- What happens if they find a problem under the old sealant
- Whether they seal over old material or remove it
- What the quote includes, VAT included or not
When something else is needed
New sealant cannot fix everything, and we will tell you before work begins. Sealant will not put right:
- A sealed unit that has misted inside
- Failed flashing around a conservatory
- A sagging or failing conservatory roof
If in doubt, ring 0345 464 0079 or drop us an email and we’ll say what we think before you book.
