Glazing silicone in Netherne on-the-Hill, done properly
Glazing silicone is a maintenance item. Sun, rain and movement wear it down and cracked joints let water in. Resealing puts that right. We work on shower screens, glass-to-frame joints and conservatory frames, and common reasons people get in touch are mouldy sealant around glass panels and sealant that was laid over old silicone and failed.
Much of London’s older housing was built with timber sash windows, some still in place and some long since replaced. Either way, the mastic between frame and brickwork is what stops draughts and rain getting in.
There’s a 12-month guarantee on every job, large or small.

What affects the cost of glazing silicone
For a quick quote, just ask. The main things that affect it are:
- The size of the job
- The number of rooms or windows
- Which sealant suits the joint
- Whether old sealant or filler has to be cut out
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you are unsure, call 0345 464 0079 or email us for an honest opinion and a quote.
What we need to know
There’s no need for technical detail. Just tell us:
- Any access issues, like height or stairs
- Any previous sealing or DIY work
- Roughly how big the job is
- Photos by email, if that’s easy
Call for a quick quote, or send an email if you’d rather. Describe what needs sealing and we’ll explain what’s involved before giving you a price.
What happens if it’s left?
Fixing a leaking screen early protects what’s underneath. A small leak can reach the floor below before it shows. 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. Putting it right early is much less trouble for homes in Netherne on-the-Hill.
The cost reflects the work involved, not a rough estimate. That’s why we ask about the job first.
Why book with us
- Domestic, commercial and hotel work
- Neat joints and a tidy finish

- An ARBOMaster approved applicator

Questions from Netherne on-the-Hill
Is parking an issue for glazing silicone in Netherne on-the-Hill?
Parking in Netherne on-the-Hill, as in most of London, takes a little planning: a visitor permit or a bay close to the door helps a lot, so mention what’s available when you book.
Do you work for landlords with property near Coulsdon South station?
Yes, rental work is part of what we do. Just call 0345 464 0079 or drop us an email and tell us about the property, and we will give you a clear price.
Can I add another job to the visit?
Yes. Tell us about everything you’d like done.
Are you insured?
Yes, we are fully insured.
Are you ARBOMaster approved?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
Is a special sealant needed for glass?
Glass needs a sealant made for glazing. We use neutral-cure glazing silicone with anti-fungal products in bathrooms.
How much does glazing silicone cost in Netherne on-the-Hill?
The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote and we will talk you through it.
Can you work on commercial sites?
Yes. Commercial and hotel work is a large part of what we do, as well as homes. We can talk about working times when we quote.
Do you need glazing silicone in Netherne on-the-Hill?
Heat and cold make glass and frames move, and they do not move by the same amount. In time, the sealant splits or pulls away.
People usually contact us after spotting something like this:
- Sealant that was laid over old silicone and failed
- Leaks where conservatory glass meets the frame
- Failed sealant around rooflight glass
- Cracked silicone between glass panels
If you look after a building such as Coulsdon Sixth Form College, its window and door frames need their mastic kept sound, just like a home’s.

Exposed frame joints wear with the weather. A fresh bead seals them again.
Glass-to-frame joints
We cut the old silicone from the glass without scratching it and reseal with glazing silicone.
Glazing silicone in Netherne on-the-Hill: local notes
The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. In a converted house or block, who looks after the windows depends on the lease, so check that before booking.
Netherne on-the-Hill is in London, so parking needs planning: let us know about parking bays, permits or a driveway. In the older streets around Church of St Margaret, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Keeping the joints in good condition
Aftercare is simple, and it makes a real difference:
- Look over the glazing joints once a year
- Wipe the screen down after showering
- Use a gentle glass cleaner and a soft cloth
- Check the gutters above the glazing for debris
Gentle products are best near the sealant. Strong solvents can soften or mark it.
Act on black or lifting silicone early. Once it starts to peel, water gets behind it and the leak gets worse.
