How we handle glazing silicone in Brompton
Glass and frames expand and contract differently, so the sealant between them does a lot of work. When it cracks or lets go, water gets in. We cut it out and reseal with a glazing silicone suited to the joint. Typical jobs include water tracking down the inner face of the glass and sealant that was laid over old silicone and failed, on rooflights, conservatory frames and glass-to-frame joints.
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.
Our work is backed for twelve months, in Brompton and everywhere else we cover.

Can I do it myself?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
Why deal with it now?
Leaks get worse, not better. Left, water can mark floors, damage plaster and rot timber, so it pays to deal with it early. 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 for homes in Brompton.
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all make a difference.

Windows and doors in Brompton
In a converted house or block, who looks after the windows depends on the lease, so check that before booking. 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.
As a London address, Brompton can be tricky for parking: tell us about permits, visitor bays or off-street space when you book. If you look after a building such as Hellenic College of London, its window and door frames need their mastic kept sound, just like a home’s.

FAQs for Brompton
Is Brompton in your area for glazing silicone?
Yes, Brompton is within the area we cover. Our work covers London and the South East. You can ring 0345 464 0079 or send us an email and let us know what needs doing.

Is it worth trying it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Is there any odour?
Some sealants have a smell while they cure, but it fades. Opening a window helps.
Do you hold any approvals?
Yes. We hold ARBOMaster approved applicator status and we are fully insured too.
Can you reseal the base of a glass balustrade?
We can, if the base joint is sealed. Send us photos and we’ll take a look when you ring 0345 464 0079 or email us.
Why not top up the existing silicone?
Topping up is a common cause of leaks. We remove the old silicone, clean the joint and reseal.
When is the sealant fully cured?
That depends on the sealant used, so follow the cure time we give you.

We will not take on work that won’t last, so here’s what sealant cannot put right:

Common problems we fix in Brompton
The wrong sealant is a common cause. Not every silicone sticks properly to glass, and acetoxy types can attack some frame materials.
Signs it’s time to call us include:
- Leaks from the base of a shower screen
- Cracked silicone between glass panels
- Water getting into a conservatory at the joints
- Leaking glazing joints on a rooflight
If you live in an older home near Church of St Simon Zelotes, frames set in older brick or stone need a sealant that suits the wall as well as the frame.
What your quote should include
- What happens if they find a problem under the old sealant
- How the colour is chosen
- Is the old sealant removed completely?
- What insurance they hold
Looking after it afterwards
Looking after new joints is easy:
- Don’t use a blade near the sealant
- Check the silicone on glass every year or so
- Keep conservatory gutters clear of leaves
- Ventilate the conservatory to cut condensation
Keep the new joints dry for as long as we advise so the silicone can set properly. From then on, a mild glass cleaner is all it needs.
A leaking shower screen may not show at first. Water can soak into the floor or reach the room below long before you see it.
