Glazing silicone for homes and businesses in Well Hill
Conservatory leaks often start at a sealant joint, where glass meets frame or frame meets wall. We find the joint that’s letting water in and renew it, and if it’s something sealant can’t fix, we’ll tell you. If you have silicone pulling away from the glass and new silicone smeared over old sealant, we can help.
London homes have every kind of window, from timber sashes in period terraces to aluminium and uPVC in newer blocks. Over the years, the sealant around them shrinks, cracks and pulls away, which is when draughts and damp patches appear in homes in Well Hill.
All our work comes with a one-year guarantee, wherever you are in Greater London.

How we quote for glazing silicone
You’ll get a clear quote before we start. It takes into account:
- How much old sealant there is and how hard it is to remove
- How many rooms, windows or areas are involved
- Whether there’s mould to deal with
- Whether the work is at height
Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all make a difference.
What we need to know
When you call or email, it’s useful to know:
- Access, such as stairs, a lift or height
- The rough size of the job
- Where the property is
- Pictures of the joints, sent by email
Every job is quoted individually, so the first step is telling us about yours. Just ring 0345 464 0079 or drop us an email with the details, and photos are welcome.
What we do, step by step
We work through the job in order: protect, prepare, seal, tidy. For most jobs that takes a few hours, depending on how many joints need doing. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Well Hill. It helps if you can point us to a visitor permit or a bay close to the door.

Advice
Keeping the joints in good condition
To keep the joints looking good and working properly:
- Squeegee the shower screen after each use
- Check the gutters above the glazing for debris
- Avoid scraping close to the bead
- Look over the glazing joints once a year
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.
Act on black or lifting silicone early. Peeling silicone lets water in behind and the problem grows.
Why act early in Well Hill
Dealing with a leaking shower screen early protects the floor and ceiling. A small leak can reach the floor below before it shows. In London conversions, one flat’s bathroom is often above another flat’s ceiling, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Dealing with it early is far simpler for homes in Well Hill.

Common problems we fix in Well Hill
Shower screen silicone gets wet every day. Mould gets into it and the joint starts to lift.
Signs it’s time to call us include:
- Water getting into a conservatory at the joints
- Glass-to-glass joints that have split
- Water tracking down the inner face of the glass
- A quick top-up bead that didn’t last
If you look after a building such as Chelsfield Primary School, the mastic around its windows and doors needs looking after like any other building’s.

Windows and doors in Well Hill
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 a converted house or block, who looks after the windows depends on the lease, so it’s worth checking before booking.
Letting a property close to Knockholt station? Then leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies. In the older streets around Mission Chapel, the joint between an old wall and a newer frame is normally the first place rain gets in.
