About our glazing silicone in St George in the East
Cracked, stained or lifting silicone on glass looks poor and can leak. We remove it without scratching the glass or frame and reseal the joint. Typical jobs include split or lifting silicone on glass and stained, discoloured glazing silicone, on shower screens, glass-to-frame joints and rooflights.
From mansion-block windows to modern glazing in new flats, London has every kind of frame. Over the years, the sealant around them shrinks, cracks and pulls away, which is when draughts and damp patches appear in homes in St George in the East.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

Common problems we fix in St George in the East
Not every leak is a sealant problem: failed roof panels, slipped glazing bars and blocked gutters cause them too. That is why we trace the leak first.
Look out for these signs:
- Stained, discoloured glazing silicone
- Leaking glazing joints on a rooflight
- Leaks from the base of a shower screen
- Glazing silicone that has cracked or come away
Rented homes near Shadwell station change hands often, and glazing joints are worth checking at the end of a tenancy, before a small leak grows.
Questions to ask before you book
- Whether they seal over old material or remove it
- What product goes in the joint
- How long to leave it before use
- What happens if the job turns out different

What else we do in St George in the East
Why it’s worth doing now in St George in the East
Resealing can’t fix a failed unit or a cracked panel. We say so plainly, so you can call the right trade. Converted houses in London often have a bathroom above someone else’s living room, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Putting it right early is much less trouble.
What you pay reflects the work, not guesswork. That’s why we ask a few questions first and agree the price before starting.

Your questions about glazing silicone in St George in the East
Can parking be tricky for a visit in St George in the East?
It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. That way the visit can be planned around it.
I let a flat near Shadwell station. Can you help?
Yes. We work for letting agents and landlords as well as householders. You can call 0345 464 0079 or drop us an email with the details for a clear quote.
How long does glazing silicone take?
That depends on the amount of work, but most jobs take anything from an hour or two to most of a day, depending on the size of the job. We will tell you when we quote.
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 fit new glass or sealed units?
No, our work is the silicone. A glazier replaces glass and units.
What do you put in the joint?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
Do you offer different sealant colours?
In most cases you can choose. We’ll tell you which colours the right product comes in.
Can you reseal the base of a glass balustrade?
Yes, where the base is finished with sealant. Send us pictures and we will take a look.
What we can’t put right
We’d rather tell you now than do work that will not last, so here’s what sealant cannot put right:
- Cracked or broken glass
- A sealed unit that has misted inside
- A roof that has moved or dropped
Not sure which it is? You can ring 0345 464 0079 or drop us an email and we’ll tell you honestly before you book.
Surfaces we seal
- Glass-to-glass joints
- Rooflights
- Conservatory frames

How the visit works
Every visit runs the same way: we check the joints, protect the area around them, do the work and clear up. It normally takes a few hours for most jobs. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. Mention any building rules, key holders or managing agents when you book.
- First, we trace the leak and check it’s coming through a sealant joint.
- Old silicone is cut away from the glass and frame without scratching either.
- We clean the joint with a solvent that suits the glass and frame.
- New glazing silicone goes in and is tooled to a neat finish.
- The finished joints are checked and, where it’s safe, tested with water.
How to prepare
- Mention if the joints have been sealed before
- Tell us about any water getting in
- On commercial sites, let us know about site rules

DIY sealant or a professional job?
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
How we quote for glazing silicone
We quote each job individually. These are the things that affect it:
- How many areas need sealing
- Whether there’s mould to deal with
- Which sealant suits the joint
- Access and height
There are no prices on our website, because each job is priced on what it involves. For a quick quote, please phone 0345 464 0079 or send us an email.
Helping us quote
Photos help, but a description is a good start. Please mention:
- The type of property
- Pictures of the joints, sent by email
- Where the property is
- Whether it has been sealed before
