Glazing silicone in Seven Dials, done properly
Conservatory leaks often start at a sealant joint, where glass meets frame or frame meets wall. We trace the leak to the joint and reseal it and tell you plainly if the cause is something else. We work on glass balustrade bases, glass-to-glass joints and glass-to-frame joints, and the jobs we see most are failed sealant around rooflight glass and water escaping where a screen meets the wall.
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 Seven Dials.
Your job is guaranteed for a year, as with all our work.

Aftercare tips
How long the joints last depends on use and care. We suggest:
- Stick to mild cleaners on glass
- Inspect the sealant on glazing annually
- Avoid scraping close to the bead
- Don’t leave a drip for the next storm
Don’t use blades or scrapers near the bead when cleaning the glass. Stick to a soft cloth.
A leaking shower screen may not show at first. Water can soak into the floor or reach the room below long before you see it.
Windows and doors in Seven Dials
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. With historic houses such as Benjamin Franklin House (about 0.4 miles south) nearby, there’s older building stock in the area around Seven Dials as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
As a London address, Seven Dials can be tricky for parking: tell us about permits, visitor bays or off-street space when you book. Rented homes near Tottenham Court Road station change hands often, and leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies.

Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
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 does not work out, we can still put it right.
What the job involves on each surface
Glass balustrade bases
Glass balustrades sit in a channel that is often finished with sealant. When it fails, water can sit in the channel.
Shower screens
Black or peeling silicone on a screen lets water out. A full reseal sorts it.
Landlord and commercial work in Seven Dials
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.
In hotels, rooms out of use cost money, so the work can be planned room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
What affects the quote in Seven Dials

- The type of sealant required
- Working hours on commercial sites
- How easy the joints are to reach
- The number and length of the joints
Combining jobs into one visit usually makes better use of the time than several visits. We will give you a clear quote for the lot.
Helping us quote
Photos help, but a description is a good start. Try to tell us:
- Whether it has been sealed before
- Photos by email, if that is easy
- How we’d reach the joints
- Whether it’s a home or a business
We do not publish a price list, as no two jobs are quite the same. Instead, your job gets its own clear quote. To get started, call 0345 464 0079 or drop us an email.
What we’re called out for in Seven Dials
New silicone over old silicone won’t bond. Many failed joints we see have been topped up rather than cut out leaving a path for water.
The most common problems we see are:
- New silicone smeared over old sealant
- Silicone pulling away from the glass
- Glass-to-glass joints that have split
- Conservatory leaks at frame and glazing joints
In the older streets around Soho Baptist Chapel, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Seven Dials questions
Is Seven Dials in your area for glazing silicone?
Yes, Seven Dials is within the area we cover. We work across London and the South East. You can phone 0345 464 0079 or drop us an email and tell us what needs doing, and we will give you a clear quote.
Is parking a problem for a job in Seven Dials?
Parking in Seven Dials, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day run more smoothly, so mention what’s available when you book.
Can you reseal a frameless shower screen?
Yes. The old bead comes off without marking the glass, and the joints are cleaned and resealed.
Where do you work from?
Our base is in Crawley, and we work across South East England, London and Scotland.
Can I do it myself?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
Will the old sealant be removed?
Always. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Is a special sealant needed for glass?
Glass needs a sealant made for glazing. Ours is a neutral-cure glazing silicone with anti-fungal products in bathrooms.
Will there be a smell?
Sometimes, a little. Any smell clears as the sealant cures, and ventilation helps.

How it works
Most of a good job is in the preparation, so that is where we spend the time. Joints are cleaned back and dried before anything new goes in. All told, the work 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.
- We start by finding the leak and making sure sealant is the cause.
- Old silicone is cut away from the glass and frame without scratching either.
- Surfaces are cleaned with a solvent suited to glass and the frame.
- Glazing silicone suited to the joint is applied and tooled.
- We check the joints and, where safe, run water over them.
Preparing for the visit
- Try not to wet indoor joints just before the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Let us know about parking restrictions
