Frames and glazing around Bow
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. In London conversions and blocks, the lease decides who is responsible for the frames, so check that before you book.
As a London address, Bow can be tricky for parking: let us know about parking bays, permits or a driveway. For an older house near a landmark such as St Paul Old Ford, the joint between an old wall and a newer frame is normally the first place rain gets in.
Bow is about 1 mile south-east of Hackney, in Greater London. For glazing silicone in and around Bow, it’s easy to get a quote: please ring 0345 464 0079 or send us an email.

About our glazing silicone in Bow
Frameless shower screens rely on sealant to keep water in. Leaks normally come from the wall joint or the tray joint, and we reseal both. Common call-outs are for a quick top-up bead that didn’t last and water tracking down the inner face of the glass, across glass-to-glass joints, glass-to-frame joints and rooflights.
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 Bow is something to talk through when you book.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

What else we do in Bow
How to look after the new joints
A little care helps the new joints last. We recommend:
- Clear the conservatory gutters regularly
- Use gentle products around the joints
- Stick to mild cleaners on glass
- Ventilate the conservatory to cut condensation
On shower screens, wipe or squeegee after use and let the room air. That slows mould growth on the bead.
Drips or damp near a glazing joint shouldn’t be ignored. The cause may be sealant or another part and we’ll find out which.
What we do, step by step
At the end, we look at the finished work together and explain the cure time. The visit itself normally takes a few hours, depending on how many joints need doing, depending on how much there is to do. In a London area like Bow, the main things to plan are parking and access: tell us about permits, visitor bays or off-street space, which floor we are working on and whether there’s a lift.
- First we agree the joints to be done.
- Old sealant is removed from the glass and frame.
- We clean and prepare the joint.
- We apply and tool the new silicone.
- The joints are checked before we leave.
Getting ready for the visit
- Tell us about any previous sealing or DIY attempts
- Move anything stored near the joints
- Mention any sign-in or site rules at work premises

Why it’s worth doing now in Bow
Glazing joints need a sealant made for the job. General-purpose sealant from a DIY shop may not suit glass or the frame, so we use neutral-cure glazing silicone. In a London flat, a failed joint rarely stays your problem alone: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.
Why us?
- An ARBOMaster approved applicator
- Full insurance on every job
- Any old sealant cut out fully, not covered over
- White, clear, grey or another colour, product permitting

Bow: your questions answered
I let a flat near Hackney Wick station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. Just phone 0345 464 0079 or send us an email with the address and what needs doing, and we’ll give you a clear quote.
Is Bow in your area for glazing silicone?
Yes, Bow is within the area we cover. We work across London and the South East. Just phone 0345 464 0079 or send us an email with a few details of the job, and we’ll give you a clear quote.
Will the old sealant be removed?
Always. Sealing over the old bead is the commonest cause of early failure, so we never do it.
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.
Is there any odour?
Sometimes, a little. Any smell clears as the sealant cures.
Can I choose the sealant colour?
We’ll suggest a colour to suit the surroundings. The choice depends on the product the joint needs.
Can you reseal the base of a glass balustrade?
Yes, we reseal the joint at the base channel. Fitting glass is a separate trade.
What should I tell you?
Let us know what needs doing and where, plus pictures if you have them. We will ask anything else we need to know.
When to call us in Bow
New silicone over old silicone will not bond. Many failed joints we see have been topped up rather than cut out leaving a path for water.
It’s worth asking for a quote if you see:
- Water running down inside the glass
- Leaking glazing joints on a rooflight
- Sealant that was laid over old silicone and failed
- Water getting into a conservatory at the joints
Rented homes near Hackney Wick station change hands often, and leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies.
Questions to ask before booking
- Is the old sealant removed completely?
- What insurance they hold
- How the joint is cleaned and prepared
- Whether you can choose the colour
Surface by surface
Glass balustrade bases
Balustrade bases are exposed outdoors. Renewing the sealant keeps water out of the channel.
Conservatory frames
Frame-to-wall joints on a conservatory move with the weather. We reseal them with a sealant suited to the frame.
When something else is needed
Some problems need a builder, plumber or other trade rather than us:
- Structural problems with a conservatory roof
- Failed flashing around a conservatory
- Misting between the panes of a double-glazed unit (a failed unit for a glazier)
If in doubt, phone 0345 464 0079 or email us and we will say what we think.
Surfaces we seal
- Glass balustrade bases
- Glass-to-frame joints
- Glass-to-glass joints
- Rooflights
- Conservatory frames
- Shower screens
What affects the quote in Bow
The price is agreed before any work begins. It takes into account:
- Which sealant suits the joint
- How much there is to do
- Working hours on commercial sites
- Whether old sealant or filler has to be cut out
Leaving a failed joint generally makes the job bigger, not smaller, because water and mould keep working on it. If you are unsure, call 0345 464 0079 or email us and we will give you an honest view and a quote.
Helping us quote
When you call or email, these details help:
- The address or postcode of the job
- If it’s domestic, commercial or a hotel
- Roughly how big the job is
- Any previous sealing or DIY work
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is, and we will talk you through what we’d do. Whenever you are ready, ring 0345 464 0079 or drop us an email.
