How we handle glazing silicone in Crowthorne
We work across Crowthorne on glazing joints for homes and businesses. Conservatories, rooflights, glass panels and shower screens are all part of the job, with a sealant chosen for the joint. If you’re dealing with mouldy sealant around glass panels and glazing silicone that has cracked or come away, we can put it right, whatever the surface.
Plenty of homes in a town like Crowthorne have had conservatories, patio doors or new windows added over the years. Every addition brings more joints, each wearing at its own pace. Leaks normally start at a sill, a frame head or a glazing joint.
All our work is covered by a one-year guarantee.

What affects the quote in Crowthorne
Jobs vary more than people expect. What affects the quote:
- The type of sealant required
- Whether the work is at height
- The size of the job
- Any mould that needs treating
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed. Call for a quick quote and we’ll explain what it covers.
What we need to know
There’s no need for technical detail. Just tell us:
- If someone has resealed it before
- Any access issues, like height or stairs
- A few pictures by email, if you can
- The type of property
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints, and email photos if that is easy.
Different surfaces, different methods
Conservatory frames
The joints where the conservatory meets the house take a lot of movement. We reseal them with a sealant suited to the frame.
Shower screens
Most shower screen leaks come from the wall or tray joint. We reseal both with anti-fungal silicone.
Questions from Crowthorne
I let a flat near Crowthorne station. Can you help?
Yes. We work for landlords and agents as well as householders, and several properties can go on one quote. Just phone 0345 464 0079 or send us an email with the address and what needs doing, and we’ll give you a clear price.
Can you do glazing silicone in Crowthorne?
Yes. Our work covers London and the South East, and Crowthorne is part of that. You can phone 0345 464 0079 or send us an email and tell us what needs doing.
Do I need to be at home?
If the work is inside, we need someone to let us in. After that, you can carry on with your day.
Where is Mr Mastic based?
Our base is in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
How much does glazing silicone cost in Crowthorne?
We don’t publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. You’ll get a clear quote before any work starts.
Will resealing stop my conservatory leaking?
Often, if the leak is at a sealant joint. We trace the leak first before any sealing.
What do you put in the joint?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice, and we’ll tell you what we are using.
Do you take out the old sealant first?
Yes, every time. New silicone doesn’t stick to old silicone, so any old material comes out before anything new goes in.
Do you need glazing silicone in Crowthorne?
Heat and cold make glass and frames move at different rates. In time, the sealant splits or pulls away.
People generally contact us when they notice one of these:
- Conservatory leaks at frame and glazing joints
- Mouldy sealant around glass panels
- New silicone smeared over old sealant
- Water escaping where a screen meets the wall
Homes close to Crowthorne Methodist Church include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
What your quote should include
- What happens if they find a problem under the old sealant
- How long the guarantee is
- Is the old sealant removed completely?
- Whether you can choose the colour
For landlords and businesses
Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. Several properties can be quoted together.
We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements and we will give you a quote.
When something else is needed
Honest advice matters more to us than a booking, so here’s what new sealant will not do:
- Misting between the panes of a double-glazed unit (a failed unit for a glazier)
- A sagging or failing conservatory roof
- Leaks from the roof covering or flashing (a roofer’s job)
If in doubt, ring 0345 464 0079 or email us and we will say what we think.
Surfaces we seal
- Glass balustrade bases
- Conservatory frames
- Glass-to-glass joints
- Shower screens
- Glass-to-frame joints
- Rooflights
Why it’s worth doing now in Crowthorne
A leaking joint won’t fix itself. Left, water can mark floors, damage plaster and rot timber so early action saves a bigger repair. Black mould and gaps in sealant do not fix themselves, and in a busy household in Crowthorne they spread with every shower and every downpour. Replacing the sealant now is the simplest fix.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.
Why us?
- Neat joints and a tidy finish
- 20+ years of sealant experience
- An ARBOMaster approved applicator
- Colour picked to suit the job
