New Cross Glazing Silicone
Problem with your glazing joints in New Cross? We cut out the old, prepare the joints and apply the right sealant, with a one-year guarantee.
- Leaks where conservatory glass meets the frame
- Sealant that was laid over old silicone and failed
- Water running down inside the glass
Glazing silicone in New Cross, done properly
We don’t replace glass and a misted double-glazed unit needs a glazier. What we do is the silicone around the glass, which is where many leaks start. We work on rooflights, glass-to-glass joints and conservatory frames, and common reasons people get in touch are water running down inside the glass and stained, discoloured glazing silicone.
Much of London’s older housing was built with timber sash windows, some still in place and some long since replaced. Whatever is in the opening now, the joint between frame and wall is what keeps the weather out.
A one-year guarantee comes with the work, just as it does everywhere we cover.

Windows and doors in New Cross
The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. In a converted house or block, who looks after the windows depends on the lease, so it’s worth checking before booking.
For an older house near a landmark such as St James's Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. Schools such as Myatt Garden Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.

What we do, step by step
All our tools and materials come with us in the van, so you don’t need to buy or prepare anything. After a quick look at the joints together, we protect the area and start. It normally takes anything from an hour or two to most of a day, depending on the size of the job. In a London area like New Cross, the main things to plan are parking and access: let us know about parking, the floor we will be working on and any lift or shared entrance.
- We find where water is getting in and check whether it’s a sealant joint.
- Old silicone is cut away from the glass and frame without scratching either.
- The glass and frame are cleaned and degreased.
- Glazing silicone suited to the joint is applied and tooled.
- The finished joints are checked and, where it’s safe, tested with water.
How to prepare
- For business premises, tell us about site rules or sign-in
- Try not to wet indoor joints just before the visit
- Mention any tricky access

Advice
Your questions about glazing silicone in New Cross
I let a flat near New Cross station. Can you help?
Yes. We work for letting agents and landlords as well as householders. You can ring 0345 464 0079 or drop us an email with the details for a clear quote.
Can parking be tricky for a visit in New Cross?
London parking needs a little planning, so let us know about permits, bays or a driveway when you book. The visit is then planned around what’s available.
Do you work in New Cross?
Yes. From our base in Crawley, we cover South East England, London and all of Scotland, and that includes New Cross.
Is a special sealant needed for glass?
We pick a glazing silicone to suit the materials. Neutral-cure products suit most glass and frames.
Can I add another job to the visit?
Yes, and it often makes sense. Doing several areas at once is normally more efficient, so mention them when you ask for a quote.
How long should I leave it?
It depends on the product. We tell you how long to leave it before we go.
Do you hold any approvals?
Yes. We hold ARBOMaster approved applicator status, and we are fully insured.
Do I need to be at home?
That depends on where the joints are. Inside work needs someone to give us access, and for outside work we will agree access with you when we book.
Can I do it myself?
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so tell us about it when you ask for a quote.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Why act early in New Cross
Dealing with a leaking shower screen early protects the floor and ceiling. Water from a failed joint can soak into the floor before it shows. Converted houses in London often have a bathroom above someone else’s living room, 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.
The cost reflects the work involved, not a rough estimate. That is why we ask about the job first.

Quotes for glazing silicone in New Cross
Every job gets its own quote. These are the things that affect it:
- Which sealant suits the joint
- How many areas need sealing
- How easy the joints are to reach
- Working hours on commercial sites
Leaving a failed joint generally makes the job bigger, not smaller, as water and mould keep getting in. If you’re not sure whether it needs doing, call 0345 464 0079 or email us for an honest opinion and a quote.
Asking for a quote
When you call or email, it’s useful to know:
- Access, such as stairs, a lift or height
- Where the job is, and your postcode
- Roughly how big the job is
- Pictures of the joints, sent by email
It all starts with a short chat. Describe the problem, the location and the size of the job. When it suits you, ring 0345 464 0079 or drop us an email.
Honest limits
Honest advice matters more to us than a booking, so here’s what sealant cannot fix:
- A sagging or failing conservatory roof
- Frames that have decayed or split
- Water coming through the roof rather than a sealant joint
If you’re not sure, just phone 0345 464 0079 or email us and we will give you a straight answer before booking.
Joints and surfaces we work on
- Glass-to-frame joints
- Glass-to-glass joints
- Conservatory frames
- Shower screens
- Glass balustrade bases
- Rooflights
Signs you need glazing silicone in New Cross
Shower screen silicone gets wet every day. Mould grows into the bead and the joint starts to lift.
Common reasons people contact us include:
- Shower screens leaking along the wall or tray
- Sealant that was laid over old silicone and failed
- Mouldy sealant around glass panels
- Water tracking down the inner face of the glass
New Cross is in London, so parking needs planning: let us know about parking bays, permits or a driveway.
What to look for in a quote
- Which colour the sealant will be
- What product goes in the joint
- Is VAT in the price?
- When the joint can take water or movement
Keeping the joints in good condition
After the cure time, these simple habits help:
- Use a gentle glass cleaner and a soft cloth
- Clear the conservatory gutters regularly
- Check the silicone on glass every year or so
- Keep scrapers and blades away from the silicone
Don’t use blades or scrapers near the bead when cleaning the glass. Stick to a soft cloth.
A small conservatory leak soon spreads. Water runs along frames and down walls, so get it looked at when you first see it.
