Castle Green: your questions answered
Is parking an issue for glazing silicone in Castle Green?
Parking in Castle Green, as in most of London, takes a little planning: a visitor permit or a bay close to the door helps a lot.
Is Castle Green in your area for glazing silicone?
Yes, Castle Green is within the area we cover. We work across London and the South East. You can phone 0345 464 0079 or email us and let us know what needs doing.
Is a special sealant needed for glass?
We use a neutral-cure glazing silicone that suits the glass and frame. Shower screens get anti-fungal silicone.
Do you fit new glass or sealed units?
That is not something we do. Misting between panes means the sealed unit has failed and needs replacing by a glazier.
Can you fix a leaking conservatory?
If the water is coming in through failed sealant joints, yes. If it’s a broken panel, failed unit or roof problem, we will tell you.
Can I do it myself?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. If it doesn’t work out, we can redo it.
Are you fully insured?
Yes. We are fully insured.
Are you an approved applicator?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
Glazing silicone for homes and businesses in Castle Green
Glazing silicone that has yellowed, blackened or come away looks poor and can leak. We remove it without scratching the glass or frame and reseal the joint. Common call-outs are for leaking glazing joints on a rooflight and water getting into a conservatory at the joints, across shower screens, rooflights and glass-to-glass joints.
From mansion-block windows to modern glazing in new flats, London has every kind of frame. The mastic around them dries out and cracks with age, which is when draughts and damp patches appear in homes in Castle Green.
Whatever the size of the job, it’s backed by our 12-month guarantee in Castle Green and across Greater London.

DIY sealant or a professional job?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Why act early in Castle Green
A quick bead over the old sealant might stop a drip for a while, but new silicone won’t bond to old, and the leak normally returns. 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.
Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs, plus any working-time requirements on site. Call for a quick quote and we’ll explain what it covers.
Why book with us
- Rated 4.9 stars on Google
- A sealant colour to suit the surroundings
- Approved under the ARBOMaster scheme
- Anti-fungal silicone where joints get wet

What affects the cost of glazing silicone
The quote reflects the job in front of us. We look at:
- The number of rooms or windows
- Which sealant suits the joint
- Mould in or behind the old joints
- The size of the job
What it costs depends on the size of the job, how much old material has to come out and how easy the joints are to reach. We give a clear quote before any work starts, so you know where you stand.
Asking for a quote
A few details help us give you an accurate quote. When you ask for a quote, tell us:
- What’s wrong with the joints now
- If it’s domestic, commercial or a hotel
- The address or postcode of the job
- Access, such as stairs, a lift or height
We don’t publish a price list, because every job is different. Instead, your job gets its own clear quote. To get started, ring 0345 464 0079 or email us.
Keeping the joints in good condition
A little care helps the new joints last. We recommend:
- Keep scrapers and blades away from the silicone
- Keep air moving in the conservatory
- Don’t leave a drip for the next storm
- Check the silicone on glass every year or so
Use mild cleaners on and around the silicone. Strong solvents can soften or mark it.
Act on black or lifting silicone early. Peeling silicone lets water in behind and the problem grows.

What we do, step by step

Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Castle Green. It helps if you can point us to a visitor permit or a bay close to the door.

What the job involves on each surface
Rooflights
We reseal the glazing joints on rooflights. If the leak is from the roof around it, a roofer needs to look.
Glass-to-frame joints
Glass-to-frame joints need a sealant that bonds to both. We use a glazing silicone suited to each.
Windows and doors in Castle Green
In London conversions and blocks, the lease decides who is responsible for the frames, so check that before you book. The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Managing a site like Jo Richardson Community School? Then the mastic around its windows and doors needs looking after like any other building’s. In the older streets around St John the Divine, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. As a London address, Castle Green can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.
