Glazing silicone in Barbican Estate
Glass, frames and walls all move at different rates, and the silicone between them takes the strain. Once it splits or comes away, water finds a way through. We cut it out and reseal with a glazing silicone suited to the joint. Typical jobs include water tracking down the inner face of the glass and leaks from the base of a shower screen, across glass balustrade bases, shower screens and glass-to-glass joints.
London’s Victorian and Edwardian terraces were built with timber sash windows, and many still have them or their replacements. Whatever is in the opening now, the joint between frame and wall is what keeps the weather out.
Whatever the size of the job, you get the same one-year guarantee in Barbican Estate and across Greater London.

Can you reseal a frameless shower screen?
Yes. We remove the old silicone carefully, and the joints are cleaned and resealed.
What sealant do you use on glazing?
A neutral-cure glazing silicone that suits the glass and frame. In bathrooms, we use anti-fungal silicone.
What information do you need?
Where the job is, what the problem is and roughly how big it is. If you can, email a few pictures.
Can you fix a leaking conservatory?
If the water is coming in through failed sealant joints, yes. If the cause is the roof, a panel or a unit, we will say so.
What sealant do you use?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
How long does the job take?
It depends on the size of the job, but as a guide it takes a few hours, depending on how many joints need doing. We will tell you when we quote.
What affects the quote in Barbican Estate
Some jobs are bigger than they look, and some smaller. What affects the quote:
- The product the joint needs
- The number and length of the joints
- Access and height
- Whether old sealant or filler has to be cut out
Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference.
Helping us quote
What to tell us when you ask for a quote:
- The type of property
- Pictures of the joints, sent by email
- The address or postcode of the job
- The rough size of the job
A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is, and add photos by email if you can.
Glazing silicone in Barbican Estate: local notes
With historic houses such as Mansion House (about 0.5 miles south-east) nearby, there’s older building stock in the area around Barbican Estate as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. In London conversions and blocks, the lease decides who is responsible for the frames, so it’s worth checking before booking.
Letting a property close to Moorgate station? Then glazing joints are worth checking at the end of a tenancy, before a small leak grows. As a London address, Barbican Estate can be tricky for parking: let us know about parking bays, permits or a driveway.

What we cannot put right
Sealant is not the answer to every problem, and we’d rather say so up front. It will not solve:
- Misting between the panes of a double-glazed unit (a failed unit for a glazier)
- Failed flashing around a conservatory
- Structural problems with a conservatory roof
If in doubt, ring 0345 464 0079 or email us and we will say what we think.
Surfaces we seal
- Glass balustrade bases
- Glass-to-glass joints
- Conservatory frames
- Shower screens
- Glass-to-frame joints
- Rooflights
What happens on the day
Every visit runs the same way: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and clear up. It generally takes a few hours, depending on how many joints need doing. In Barbican Estate, as in most of London, parking needs a little planning. A visitor permit or a nearby bay makes the visit run more smoothly.
- We look at the glazing and agree which joints need resealing.
- 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.
How to prepare
- For business premises, tell us about site rules or sign-in
- Let us know about earlier repairs to the joints
- Mention any tricky access

Advice
Common problems we fix in Barbican Estate
Heat and cold make glass and frames move, and they do not move by the same amount. In time, the sealant splits or pulls away.
People usually contact us when they notice something like this:
- Leaks from the base of a shower screen
- Leaks where conservatory glass meets the frame
- Mouldy sealant around glass panels
- Failed joints on frameless glass
Schools such as Prior Weston Primary School and Children's Centre are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.
Before booking anyone
- What product goes in the joint
- How the surfaces are prepared before sealing
- How the colour is chosen
- What the quote includes, VAT included or not
Aftercare tips
No joint lasts for ever, but care makes a real difference. A few tips:
- Ventilate the conservatory to cut condensation
- Inspect the sealant on glazing annually
- Clear the conservatory gutters regularly
- Avoid scraping close to the bead
Follow the cure time we give you before the joints get wet so the silicone can set properly. After that, clean glass with a mild cleaner.
Don’t leave lifting or mouldy silicone on glazing. Once it starts to peel, water gets behind it and the leak gets worse.
What the job involves on each surface
Glass balustrade bases
Outdoor balustrade joints face the weather. Renewing the sealant keeps water out of the channel.
Glass-to-frame joints
The sealant must stick to glass and frame alike. We choose a product that suits both.
