Glazing silicone in Sutton Common
We don’t replace glass and a misted double-glazed unit needs a glazier. Our work is the sealant joints, which is where many leaks start. If you have failed sealant around rooflight glass and drips on the inside of a conservatory window, we can help, on glass-to-glass joints, glass balustrade bases and rooflights alike.
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.
You’re covered for a year from the day we finish. If there’s a problem with it, please call 0345 464 0079 or drop us an email.

Leave it or put it right?
Resealing cannot fix a failed unit or a cracked panel. We’ll tell you that rather than seal it anyway and point you to a glazier or roofer. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and once it shows in Sutton Common, the repair is bigger than a sealant job.
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
Why book with us
- Colour agreed with you before we start
- ARBOMaster approved applicator
- White, clear, grey or coloured to suit, where the product allows
- Any old sealant cut out fully, not covered over

What affects the cost of glazing silicone
The quote reflects the job in front of us. We look at:
- Whether the work is at height
- Mould in or behind the old joints
- Whether old sealant or filler has to be cut out
- The type of sealant required
A failed joint rarely gets cheaper to fix by waiting. If you are unsure, phone 0345 464 0079 or email us and we’ll give you an honest view and a quote.
Asking for a quote
A few details help us give you an accurate quote. When you ask for a quote, tell us:
- Any previous sealing or DIY work
- Roughly how big the job is
- A few photos by email, if you can
- Whether it’s a home or a business
For a quick quote, get us on the phone, or email us if that is easier. Tell us about the joints that need doing and we’ll explain what’s involved before giving you a price.
When something else is needed
Some problems need a builder, plumber or other trade rather than us:
- Structural problems with a conservatory roof
- A broken pane or roof panel
- Misting between the panes of a double-glazed unit (a failed unit for a glazier)
If you are not sure, just call 0345 464 0079 or email us and we’ll give you a straight answer.
Surfaces we seal
- Glass-to-glass joints
- Conservatory frames
- Glass balustrade bases
- Rooflights
- Shower screens
- Glass-to-frame joints
Should I try it myself first?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Windows and doors in Sutton Common
In London conversions and blocks, the lease decides who is responsible for the frames, so it’s worth checking before booking. Historic houses like Nonsuch Mansion (about 2.1 miles south-west) are a reminder that the area around Sutton Common has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
Rented homes near St Helier station change hands often, and a shower screen or conservatory joint that leaks is easier to reseal while the property is empty. In the older streets around St Lawrence Church, the joint between an old wall and a newer frame is normally the first place rain gets in.

What we do, step by step
You do not need to clear the whole room or building before we come, only the area right around the joints. We protect the rest, and the job takes a few hours for most jobs in most cases. In Sutton Common, flats, stairs and shared entrances are part of the routine. Mention any building rules, key holders or managing agents when you book.
- First we agree the joints to be done.
- We cut away the failed silicone.
- The surfaces are cleaned with a suitable solvent.
- We apply and tool the new silicone.
- We inspect the work and test it where we can.
Before we arrive
- Tell us about access, such as stairs, a lift or high-level joints
- Move anything stored near the joints
- For indoor joints, keep the area dry beforehand if you can

Sutton Common: your questions answered
I let a flat near St Helier station. Can you help?
Yes, we work for landlords and letting agents. You can call 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before any work starts.
Is Sutton Common in your area for glazing silicone?
Yes. We work across London and the South East, and Sutton Common is part of that. You can ring 0345 464 0079 or drop us an email and tell us what needs doing, and we’ll give you a clear quote.
Can you quote for more than one area?
Of course. Doing several areas at once is normally more efficient, so mention them when you ask for a quote.
Will it make a mess?
Tidy work is part of the job. We protect what’s around the joints.
Do you replace glass?
No. Misting between panes means the sealed unit has failed and needs replacing by a glazier.
When is the sealant fully cured?
That depends on the sealant used, so please follow the time we give you when we finish.
Where are you based?
We are a Crawley-based firm. Our area covers South East England, London and Scotland.
Can you fix a leaking conservatory?
Yes, when the leak is a failed sealant joint. If the cause is the roof, a panel or a unit, we will say so.
Landlords, agents and businesses in Sutton Common
Letting agents often deal with us directly. 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. Several properties can go on one quote.

When to call us in Sutton Common
Heat and cold make glass and frames move, and they don’t move by the same amount. In time, the sealant splits or pulls away.
Look out for any of the following:
- New silicone smeared over old sealant
- Water running down inside the glass
- Leaking glazing joints on a rooflight
- Stained, discoloured glazing silicone
If you look after a building such as Abbey Primary School, its window and door frames need their mastic kept sound, just like a home’s.
Questions to ask before booking
- What product goes in the joint
- Whether they seal over old material or remove it
- Which colour the sealant will be
- How long the guarantee is
