How we handle glazing silicone in Gunnersbury
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. We are often asked to deal with glazing silicone that has cracked or come away and leaking glazing joints on a rooflight, across glass-to-frame joints, glass-to-glass joints and rooflights.
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.
Whatever the size of the job, you get the same 12-month guarantee in Gunnersbury and across Greater London.

Gunnersbury homes and the weather
Historic houses like Gunnersbury Park (about 0.7 miles north-west) are a reminder that the area around Gunnersbury 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. London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
In the older streets around St Michael's Church, the joint between an old wall and a newer frame is normally the first place rain gets in. If you let a flat or house near Gunnersbury station, leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies. Gunnersbury is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.

Questions from Gunnersbury
Can you do glazing silicone in Gunnersbury?
Yes, Gunnersbury is within the area we cover. Our work covers London and the South East. Just phone 0345 464 0079 or email us with a few details of the job, and we will give you a clear quote.
Is parking an issue for glazing silicone in Gunnersbury?
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.
What guarantee do I get?
There’s a 12-month guarantee on every job, glazing sealant included.
Where do you work from?
Our base is Crawley. Our area covers South East England, London and Scotland.
What sealant do you use?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference.
Can you just put new silicone over the old?
Many leaks we see come from exactly that. We remove the old silicone, clean the joint and reseal.
Can you replace a misted double-glazed unit?
No, our work is the silicone. A glazier replaces glass and units.
Will resealing stop my conservatory leaking?
In many cases, as long as sealant is the cause. We trace the leak first, so you know what you’re paying for.
For landlords and businesses
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
In hotels, rooms out of use cost money, so we plan the work room by room. We have worked in hotels as well as homes and businesses.
Should I try it myself first?
If you’ve already had a go yourself, that is fine. We cut it out and start again.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
What we do, step by step
Before we leave, we go over the finished joints with you and tell you how long to leave it. The visit itself generally takes a few hours, depending on how many joints need doing, depending on how much there is to do. In Gunnersbury, as in most of London, parking needs a little planning. A visitor permit or a nearby bay makes the visit run more smoothly.
- We trace the leak and confirm it’s a sealant joint.
- The failed silicone is cut out without marking the glass or frame.
- The joint is cleaned and degreased.
- We lay the new bead and tool it smooth.
- We check the finished joints and test with water where it’s safe.
Before we arrive
- For business premises, tell us about site rules or sign-in
- Move anything stored near the joints
- Tell us about access, such as stairs, a lift or high-level joints

Advice
What sealant work can’t fix
To be straight with you, some problems need a different trade:
- Rotten or badly damaged frames
- Structural problems with a conservatory roof
- A sealed unit that has misted inside
If you are not sure, just call 0345 464 0079 or send us an email and we will give you a straight answer before you book.
Where we work in Gunnersbury
- Glass-to-frame joints
- Glass-to-glass joints
- Rooflights
- Glass balustrade bases
- Shower screens
- Conservatory frames
Why deal with it now?
Resealing cannot fix a failed unit or a cracked panel. We will tell you that rather than seal it anyway, so you can call the right trade. In a flat in Gunnersbury, failed sealant seldom stays inside your own four walls: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.
Doing several joints on one visit normally makes better use of the time than several visits. We will give you a clear price for the lot.
Why book with us
- Old sealant always removed completely
- Trusted Arbo and Everbuild sealants
- Sanitary silicone with an anti-fungal additive in wet areas
- An ARBOMaster approved applicator
How we quote for glazing silicone
You will get a clear quote before any work starts. It’s based on:
- How many rooms, windows or areas are involved
- Whether the work is at height

- Any mould that needs treating
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. You will know the price before we begin.
Helping us quote
Photos by email are helpful but not essential. Please mention:
- Whether it’s a home or a business
- The address or postcode of the job
- A few photos by email, if you can
- Access, such as stairs, a lift or height
It all starts with a short chat. Describe the problem, the location and the size of the job, and we will talk you through what we’d do. When it suits you, phone 0345 464 0079 or send us an email.
Aftercare tips
After the cure time, these simple habits help:
- Check the gutters above the glazing for debris
- Run a squeegee over the glass when you are done
- Look over the glazing joints once a year
- Act on drips or damp patches early
Check the joints once a year. Catching a split early keeps the repair small.
Damp patches, drips and condensation along a joint are worth checking. It may be sealant, or something else and we’ll find out which.
