Signs you need glazing silicone in Avery Hill
Silicone will not bond to a dirty surface. Where the joint wasn’t cleaned and degreased the sealant may lift within a few years.
It’s worth asking for a quote if you see:
- Sealant that was laid over old silicone and failed
- Glazing silicone that has cracked or come away
- Cracked silicone between glass panels
- Shower screens leaking along the wall or tray
As a London address, Avery Hill can be tricky for parking: let us know about parking bays, permits or a driveway.

How we handle glazing silicone in Avery Hill
We work across Avery Hill on glazing joints for homes and businesses. Conservatories, rooflights, glass panels and shower screens are all part of the job, with a sealant chosen for the joint. If you’re dealing with leaking glazing joints on a rooflight and stained, discoloured glazing silicone, we can help, on shower screens, conservatory frames and rooflights alike.
Many London homes are flats, with windows high above the street. Who looks after the outside of the frames can depend on the lease, so check that first, and access in Avery Hill is something to talk through when you book.
A one-year guarantee comes as standard, so you’re covered after we’ve gone.

What happens if it’s left?
A quick bead over the old sealant might stop a drip for a while, but silicone does not stick to silicone, and the leak usually returns. A proper reseal is the lasting answer. In a flat in Avery Hill, failed sealant seldom stays inside your own four walls: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
Why book with us
- Sealant colour chosen to suit
- A 12-month guarantee on all work
- Experience in homes, commercial sites and hotels
- You choose the colour before work begins

How the job changes by surface
Conservatory frames
Conservatory frame joints are a common source of leaks. We remove the failed sealant and renew it.
Glass-to-frame joints
Where glass sits in a frame, silicone keeps water out. A failed bead lets water in.
The process
Good joint work is mostly preparation, and we don’t rush it. Every joint is cleaned and dried before new material goes in. All told, the work takes anything from an hour or two to most of a day, depending on the size of the job. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. If the building has a concierge, managing agent or access rules, tell us when you book.
- 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.
- A neutral-cure glazing silicone is applied and tooled.
- Each joint is checked and, where possible, water-tested.
Before we arrive
- Where the joints are inside, avoid wetting them before we arrive
- Let us know if you’ve seen damp or leaks
- Mention any sign-in or site rules at work premises

What glazing silicone looks like in Avery Hill
Historic houses like Eltham Palace (about 1.2 miles west) are a reminder that the area around Avery Hill has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. In a converted house or block, who looks after the windows depends on the lease, so it’s worth checking before booking.
Managing a site like Stationers' Crown Woods Academy? Then larger buildings have plenty of frames, and the mastic around each one ages. Rented homes near Falconwood station change hands often, and glazing joints are worth checking at the end of a tenancy, before a small leak grows.

Aftercare tips
Aftercare is simple, and it makes a real difference:
- Wipe the screen down after showering
- Check the gutters above the glazing for debris
- Don’t use a blade near the sealant
- Check the silicone on glass every year or so
Use mild cleaners on and around the silicone. Strong solvents can soften or mark it.
Drips or damp near a glazing joint shouldn’t be ignored. It may be sealant, or something else and we will find out which.
