Can I do it myself?
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.
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
How we handle glazing silicone in Upton
A frameless shower screen depends on its silicone. Leaks normally come from the wall joint or the tray joint and both get fresh anti-fungal silicone. Common call-outs are for stained, discoloured glazing silicone and a quick top-up bead that didn’t last, on shower screens, glass-to-frame joints and conservatory frames.
London homes have every kind of window, from timber sashes in period terraces to aluminium and uPVC in newer blocks. The mastic around them dries out and cracks with age, letting in draughts and water.
All of our work is guaranteed for twelve months, in Upton and everywhere else we cover.

How we quote for glazing silicone
Some jobs are bigger than they look, and some smaller. What affects the quote:
- How easy the joints are to reach
- Whether there’s mould to deal with
- How many rooms, windows or areas are involved
- Any working-time requirements on site
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part.
What we need to know
When you call or email, it’s useful to know:
- Where the property is
- Photos by email, if that is easy
- Any previous sealing or DIY work
- Access, such as stairs, a lift or height
If you are in Upton and need glazing silicone, ring 0345 464 0079 or drop us an email. Tell us what the problem is and where, and we’ll agree the price before any work begins.
Aftercare tips
No joint lasts for ever, but care makes a real difference. A few tips:
- Look over the glazing joints once a year
- Wipe the screen down after showering
- Open vents or windows to let moisture out
- Keep conservatory gutters clear of leaves
Use mild cleaners on and around the silicone. Strong solvents can soften or mark it.
Cracked glazing silicone means the joint has failed. Resealing now is a small job, compared with repairing damaged frames or plaster.
What happens if it’s left?
A leaking joint will not fix itself. Left, water can mark floors, damage plaster and rot timber so early action saves a bigger repair. Converted houses in London often have a bathroom above someone else’s living room, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Putting it right early is much less trouble for homes in Upton.
Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs, plus any working-time requirements on site. Call for a quick quote and we will go through it with you.

The process
On the day, there’s very little for you to do. Point us to the joints and we will get on with it. The work itself takes anything from an hour or two to most of a day, depending on the size of the job. In Upton, as in most of London, parking needs a little planning. It helps if you can point us to a visitor permit or a bay close to the door.
- We find where water is getting in and check whether it’s a sealant joint.
- The old sealant is removed from the glass and frame without scratching them.
- The glass and frame are cleaned and degreased.
- We apply a neutral-cure glazing silicone and tool it smooth.
- The finished joints are checked and, where it’s safe, tested with water.
Before we arrive
- For business premises, tell us about site rules or sign-in
- Move anything stored near the joints
- Let us know about earlier repairs to the joints

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 are ready, call 0345 464 0079 or send us an email.

Frames and glazing around Upton
In a converted house or block, who looks after the windows depends on the lease, so check that before you book. With historic houses such as Valentines Mansion (about 2.8 miles north-east) nearby, there’s older building stock in the area around Upton as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
For site and facilities teams at buildings such as Elmhurst Primary School, larger buildings have plenty of frames, and the mastic around each one ages. For an older house near a landmark such as St Peter's Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. If you let a flat or house near Forest Gate station, a shower screen or conservatory joint that leaks is easier to reseal while the property is empty.

Old sealant is removed carefully from the glass before new glazing silicone goes in.
Glass balustrade bases
Glass balustrades sit in a channel that’s often finished with sealant. Failed sealant there lets water collect.
