How we handle glazing silicone in New Addington
Not every silicone suits glass. We use a neutral-cure glazing silicone, which suits glass and most frame materials, finished with a neat, even bead. Common call-outs are for new silicone smeared over old sealant and conservatory leaks at frame and glazing joints, on glass balustrade bases, rooflights and conservatory frames.
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, letting in draughts and water.
We stand behind the work with a one-year guarantee, so you are not left on your own once the job is done.

How to look after the new joints
Aftercare is simple, and it makes a real difference:
- Wipe the screen down after showering
- Open vents or windows to let moisture out
- Inspect the sealant on glazing annually
- Avoid scraping close to the bead
Keep the new joints dry for as long as we advise. After that, clean glass with a mild cleaner.
Cracked glazing silicone means the joint has failed. Resealing now is a small job compared with fixing water damage later.

When it is not the sealant
A few problems are outside what sealant work can do:
- A broken pane or roof panel
- A sealed unit that has misted inside
- Leaks from the roof covering or flashing (a roofer’s job)
If in doubt, call 0345 464 0079 or drop us an email and we will say what we think before booking.

How we quote for glazing silicone
Every job gets its own quote. These are the things that affect it:
- How much there is to do
- How much old sealant there is and how hard it is to remove
- Mould in or behind the old joints
- When we can work, for business premises
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
What to tell us for a quote
What to tell us when you ask for a quote:
- The rough size of the job
- A few pictures by email, if you can
- The type of property
- The problem you’ve noticed
Quotes start with a quick conversation. Describe the problem, the location and the size of the job, and we will explain how we’d tackle it. Whenever you are ready, ring 0345 464 0079 or drop us an email.
Can I do it myself?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
What we do, step by step
We work through the job in order: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours, depending on how many joints need doing, and the area is left clean. For a job in New Addington, parking and access are the things to plan: let us know about parking, the floor we’ll be working on and any lift or shared entrance.
- We look at the glazing and agree which joints need resealing.

Advice
Windows and doors in New Addington
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. Historic houses like Addington Palace (about 1.5 miles north-west) are a reminder that the area around New Addington has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
If you live in an older home near St Edward King and Confessor, the joint between an old wall and a newer frame is usually the first place rain gets in. New Addington is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.

What we’re called out for in New Addington
Heat and cold make glass and frames move, and they don’t move by the same amount. Over years, that movement tears the silicone.
Common reasons people contact us include:
- Water running down inside the glass
- Water getting into a conservatory at the joints
- Glass-to-glass joints that have split
- New silicone smeared over old sealant
For landlords with property near Hayes (Kent) station, glazing joints are worth checking at the end of a tenancy, before a small leak grows.
