About our glazing silicone in Norbury
A frameless shower screen depends on its silicone. The joint down the wall and the one along the tray are common leak points and both get fresh anti-fungal silicone. We work on glass-to-glass joints, conservatory frames and glass balustrade bases, and people most often call us about new silicone smeared over old sealant and glazing silicone that has cracked or come away.
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, in Norbury as anywhere.
All our work comes with a one-year guarantee.

Norbury: your questions answered
I let a flat near Norbury station. Can you help?
Yes, landlords and agents are among the people we work for. You can phone 0345 464 0079 or email us with the details for a clear quote.
Can you do glazing silicone in Norbury?
Yes. We work across London and the South East, and Norbury is part of that. Just phone 0345 464 0079 or send us an email with a few details of the job.
Where is Mr Mastic based?
We’re based in Crawley, West Sussex, and we work across South East England, London and Scotland.
Can you do several jobs on one visit?
Of course. Doing several areas at once is normally more efficient.
Is balustrade sealant something you do?
Yes. The old sealant is removed and the joint resealed using a sealant that suits the materials.
Can I do it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Do you guarantee glazing sealant work?
You get our one-year guarantee on all our work.
How long will you be here?
A typical job takes a few hours, depending on how many joints need doing, including the preparation. We’ll confirm how long when we quote.
How the job changes by surface
Rooflights
Rooflight glazing joints are cut out and renewed. Leaks from the roof itself need a roofer.
Glass-to-frame joints
We cut the old silicone from the glass without scratching it before new glazing silicone goes in.
Frames and glazing around Norbury
Rainfall in the South East is lower than in much 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 you book.
In the older streets around St Oswald, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. As a London address, Norbury can be tricky for parking: let us know about parking bays, permits or a driveway.

How it works

After that, the work takes a few hours, depending on how many joints need doing. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Norbury. It helps if you can point us to a visitor permit or a bay close to the door.

Advice
Why act early in Norbury
You don’t need new glazing because the sealant has gone. Sound glass and frames normally just need resealing. Damp from a failed joint spreads quietly in older London brickwork and timber, and once it shows in Norbury, the repair is bigger than a sealant job.
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. You will know the price before we begin.
Why book with us
- Arbo and Everbuild products
- Neat joints and a tidy finish
- Colour picked to suit the job
- An ARBOMaster approved applicator

Work for landlords, hotels and businesses
Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.
Letting agents often deal with us directly. Tell us the address, the job and how access works.
Can I do it myself?
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
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.

When to call us in Norbury
Silicone will not bond to a dirty surface. If the glass and frame weren’t cleaned properly, the bead can peel away early.
Any of these means the joints need attention:
- Water running down inside the glass
- Split or lifting silicone on glass
- Water getting into a conservatory at the joints
- Leaking glazing joints on a rooflight
Letting a property close to Norbury station? Then leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies.

When it isn’t the sealant
We’d rather tell you now than do work that won’t last, so these are the limits:
- Condensation trapped between two panes
- Water coming through the roof rather than a sealant joint
- Structural problems with a conservatory roof
Not sure which it is? You can call 0345 464 0079 or email us and we will tell you honestly before booking.
