About our glazing silicone in Forty Hill
Cracked, stained or lifting silicone on glass looks poor and can leak. It comes off cleanly, without marking the glass before the new bead goes in. We work on glass-to-frame joints, rooflights and conservatory frames, and people most often call us about mouldy sealant around glass panels and conservatory leaks at frame and glazing joints.
From mansion-block windows to modern glazing in new flats, London has every kind of frame. Over the years, the sealant around them shrinks, cracks and pulls away, letting in draughts and water.
We guarantee the work for a year. If something is not right with it in that time, tell us and we will put it right.

Can I do it myself?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
If you’ve already had a go yourself, that is fine. We cut it out and start again.
Aftercare tips
Simple care keeps the joints in good condition. Our advice:
- Squeegee the shower screen after each use
- Get a new leak looked at quickly
- Ventilate the conservatory to cut condensation
- Avoid strong solvents on or near the sealant
Squeegee a shower screen after each shower and keep the room ventilated. That slows mould growth on the bead.
If silicone on glass has cracked, water is already getting in. Resealing now is a small job compared with fixing water damage later.
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 water soon finds its way back. Cutting out and resealing properly lasts. In a London flat, a failed joint rarely stays your problem alone: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.
Leaving a failed joint generally makes the job bigger, not smaller. If you’re unsure, phone 0345 464 0079 or drop us an email for an honest opinion and a quote.

Glazing silicone in Forty Hill: local notes
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. In London conversions and blocks, the lease decides who is responsible for the frames, so it’s worth checking before booking.
Managing a site like Worcesters Primary School? Then its window and door frames need their mastic kept sound, just like a home’s. Rented homes near Turkey Street station change hands often, and a shower screen or conservatory joint that leaks is easier to reseal while the property is empty.

We do. Forty Hill is part of the area we cover, and the service is the same as everywhere else.

Yes, it’s a common job. The screen is resealed with anti-fungal silicone suited to bathrooms.

That depends on where the joints are. For work indoors, someone needs to let us in, and for outside work we’ll agree access with you when we book.
The process
Most of a good job is in the preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new goes in. In total, it normally takes a few hours, depending on how many joints need doing. In Forty Hill, flats, stairs and shared entrances are part of the routine. 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.
- We remove the old sealant carefully.
- The joint is cleaned and degreased.
- A neutral-cure glazing silicone is applied and tooled.
- We check the finished joints and test with water where it’s safe.
Preparing for the visit
- Mention any parking rules near the property
- Plan for the work area to be out of bounds to pets and children
- Let us know if you’ve seen damp or leaks

Common problems we fix in Forty Hill
The wrong sealant is a common cause. Not every silicone sticks properly to glass, and acetoxy types can attack some frame materials.
Any of these means the joints need attention:
- Water tracking down the inner face of the glass
- Mouldy sealant around glass panels
- Split or lifting silicone on glass
- Water getting into a conservatory at the joints
As a London address, Forty Hill can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.
