Glazing silicone for homes and businesses in George Green
Cracked, stained or lifting silicone on glass looks poor and can leak. It comes off cleanly, without marking the glass and reseal the joint. We work on glass balustrade bases, shower screens and rooflights, and the jobs we see most are rooflight joints letting water in and glass-to-glass joints that have split.
Around George Green, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.
All our work comes with a 12-month guarantee.

George Green questions
Will you come out to George Green?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
I let a flat near Langley station. Can you help?
Yes. We work for landlords and letting agents as well as homeowners. Just call 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 replace a misted double-glazed unit?
That is not something we do. Misting between panes means the sealed unit has failed and needs replacing by a glazier.
Do you remove the old sealant?
Yes. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
Can you reseal the base of a glass balustrade?
Yes. We cut out the failed sealant and reseal the base joint with a suitable product.
What does glazing silicone cost?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. You’ll get a clear quote before work begins.
How long does the job take?
As a guide, most jobs take anything from an hour or two to most of a day, depending on the size of the job. Larger jobs naturally take longer.
Where is Mr Mastic based?
Our base is Crawley. We work across South East England, London and Scotland.
When something else is needed
In fairness, there are a few things sealant will not fix:
- Frames that have decayed or split
- A roof that has moved or dropped
- Leaks from the roof covering or flashing (a roofer’s job)
If you are not sure, just ring 0345 464 0079 or send us an email and we will give you a straight answer.

What we do, step by step
When we arrive, we start by going over the job with you, so you know exactly what we’re doing. Surfaces next to the work are protected before any work begins. The work generally takes anything from an hour or two to most of a day, depending on the size of the job. In a small place like George Green, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- First we agree the joints to be done.
- We cut away the failed silicone.
- We clean and prepare the joint.
- We apply and tool the new silicone.

Work for landlords, hotels and businesses
We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements and we’ll quote.
Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. Several properties can go on one quote.
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.
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
What affects the quote in George Green
You’ll get a clear quote before we start. It takes into account:
- Whether old sealant or filler has to be cut out
- Which sealant suits the joint
- How many rooms, windows or areas are involved
- How easy the joints are to reach
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, along with when we can work on site. Ask us for a quote and we will go through it with you.
Helping us quote
The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:
- Whether it’s a home or a business
- Photos by email, if that is easy
- How we’d reach the joints
- Any previous sealing or DIY work
For a quick quote, get us on the phone, or send an email if you’d rather. Tell us about the joints that need doing and we will explain what’s involved before giving you a price.

What we are called out for in George Green
On shower screens, constant water and cleaning products wear silicone. Mould grows into the bead and the edges begin to peel.
People generally contact us after spotting something like this:
- Stained, discoloured glazing silicone
- Failed sealant around rooflight glass
- Water tracking down the inner face of the glass
- Sealant that was laid over old silicone and failed
If you live in an older home near Parish Church of St Mary, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Frames and glazing around George Green
Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Windsor Castle (about 3.3 miles south-west) are a reminder that the area around George Green 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 look after a building such as Wexham Court Primary School, larger buildings have plenty of frames, and the mastic around each one ages. Letting a property close to Langley station? Then a shower screen or conservatory joint that leaks is easier to reseal while the property is empty.

Different surfaces, different methods
Rooflights
Rooflights get the full force of the weather. The sealant around the glass and frame wears faster than most.
Glass-to-frame joints
Silicone at the glass edge seals it into the frame. A failed bead lets water in.
