Glazing & conservatory sealant in Croydon, Greater London
Professional glazing silicone in and around Croydon, with every bit of old sealant taken out first and a 12-month guarantee.
- Water getting into a conservatory at the joints
- Leaks from the base of a shower screen
- Stained, discoloured glazing silicone
Glazing silicone in Croydon, done properly
Frameless shower screens rely on sealant to keep water in. The joint down the wall and the one along the tray are common leak points, and we reseal both. If you have silicone pulling away from the glass and water escaping where a screen meets the wall, we can help, whatever the surface.
London has a lot of flats and conversions, where windows are often on upper floors. In a converted house or block, the lease generally says who is responsible for the windows, so it’s worth checking before booking, and access in Croydon is something to talk through when you book.
All our work comes with a one-year guarantee.

How it works
At the end, we look at the finished work together. The visit itself normally takes a few hours for most jobs, depending on the size of the job. For a job in Croydon, parking and access are the things to plan: let us know about parking, the floor we will be working on and any lift or shared entrance.
- First, we check where the water gets in.
- The failed silicone is cut out without marking the glass or frame.
- We clean the glass and frame so the new silicone bonds.
- A neutral-cure glazing silicone is applied and tooled.
- We check the finished joints and test with water where it’s safe.
Before we arrive
- Tell us about any water getting in
- Mention if the joints have been sealed before
- Plan for the work area to be out of bounds to pets and children

Windows and doors in Croydon
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.
If you live in an older home near St Andrew's, the joint between an old wall and a newer frame is usually the first place rain gets in. Rented homes near South Croydon station change hands often, and leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies.
Croydon is about 9 miles south of London, in Greater London. Jobs in Croydon get the same care as everywhere else we work: old sealant removed completely, careful preparation and a 12-month guarantee. Our Greater London coverage runs to 764 places, and Croydon is one of them. Our London page covers work nearby.
We cover every part of CR0, CR2, CR9 and CR8 for glazing silicone and the streets around it. That includes homes and businesses on High Street, Church Road and Ruskin Square and the roads around them. Being close to the A235 and B243, Croydon is easy for our applicators to reach for glazing silicone. Other places close to Croydon include South Croydon (1 mile south), Coombe (1 mile east), Addiscombe (2 miles north-east), Ashburton (2 miles north-east) and Woodside (2 miles north-east). Larger places within reach include London (9 miles north), City of Westminster (10 miles north), Marylebone (11 miles north), Kensington (10 miles north-west), St Pancras (11 miles north) and Shoreditch (11 miles north).
What’s near Croydon
Locally, jobs take us to homes and businesses close to Cambridge Tutors College, Rutherford School and Keg & Grill pub and the streets around them. There’s a railway station in Croydon itself: South Croydon station. A little further out are Croydon Airport Visitor Centre (1.2 miles south-west) and Croydon University Hospital (1.7 miles north). Green spaces nearby include Roundshaw Downs and Duppas Hill.
Work for landlords, hotels and businesses
Landlords and agents in Croydon can book us as well as homeowners. Resealing between tenancies is a simple way to keep a property in good order before the next move-in.
Housing providers, facilities teams and property managers book us too. Several sites can be quoted together, and we’re fully insured for the work.
Looking after it afterwards
No joint lasts for ever, but care makes a real difference. Our tips:
- Squeegee the shower screen after each use
- Get a new leak looked at quickly
- Look over the glazing joints once a year
- Don’t use a blade near the sealant
Don’t use blades or scrapers near the bead when cleaning the glass. A soft cloth or sponge is best.
A small conservatory leak soon spreads. Water runs along frames and down walls, so get it looked at when you first see it.
Do you need glazing silicone in Croydon?
The wrong sealant is a common cause. Some products do not bond well to glass, and acetoxy types can attack some frame materials.
It’s worth asking for a quote if you see:
- Silicone pulling away from the glass
- Failed joints on frameless glass
- Mouldy sealant around glass panels
- Water escaping where a screen meets the wall
Croydon is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.
Before booking anyone
- How the colour is chosen
- When the joint can take water or movement
- How hidden problems are handled
- How the joint is cleaned and prepared
Why deal with it now?
Replacing windows or a shower screen is not needed for a failed joint. Sound glass and frames normally just need resealing. In a flat in Croydon, failed sealant seldom stays inside your own four walls: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all play a part.
What you get with us
- Over 20 years’ experience
- An ARBOMaster approved applicator
- We agree the colour with you first
- A choice of colours where the product allows

How we quote for glazing silicone
Some jobs are bigger than they look, and some smaller. What affects the quote:
- The type of sealant required
- The number of rooms or windows
- The number and length of the joints
- Whether old sealant or filler has to be cut out
Doing several joints on one visit is generally more efficient than separate visits, so tell us about everything that needs sealing. We’ll send you a clear quote for the lot.
Asking for a quote
Before you ask for a quote, have a think about:
- Whether it has been sealed before
- How we’d reach the joints
- The problem you’ve noticed
- A few pictures by email, if you can
The more we know about the job, the more useful the quote. Tell us where the job is, what’s wrong and how much there is, and add pictures by email if you can.
