Windows and doors in City of London
With historic houses such as Mansion House (about 0.2 miles south-east) nearby, there’s older building stock in the area around City of London as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. In London conversions and blocks, the lease decides who is responsible for the frames, so it’s worth checking before booking.
City of London is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book. For an older house near a landmark such as St Olave Old Jewry, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
City of London is about 1 mile north of London, in City of London. From the centre of City of London to the outskirts, we cover glazing silicone for every kind of property.
Here we cover the EC4V, EC1A, EC2M and EC2Y postcode area for glazing silicone. Local streets include Aldermanbury Square, Monkwell Square and Paternoster Square. City of London is on the A1 and A3, which makes it straightforward to reach. If you’re just outside City of London, we cover Barbican Estate (1 mile north), Bishopsgate (1 mile east), Finsbury (1 mile north), Aldgate (1 mile east) and St Luke's (1 mile north).
Landmarks near City of London
In City of London, that means homes and buildings near St Mary-at-Hill, Prior Weston Primary School and Children's Centre and Golden Fleece pub. You will also find Central Foundation Boys' School (0.8 miles north), Barts Health Archives (less than half a mile north-west) and St Alphage Garden (within half a mile north). There’s a railway station in City of London itself: London Cannon Street station. A little further out are Gabriel's Wharf (0.8 miles south-west) and London Mithraeum (less than half a mile south). Not far away are St. James's Park Lake and Barnsbury Wood.
Glazing silicone in City of London, done properly
We do not replace glass, and misting between panes means a failed sealed unit. Our work is the sealant joints, which is where many leaks start. We’re often asked to deal with failed joints on frameless glass and failed sealant around rooflight glass, on rooflights, shower screens and glass balustrade bases.
Many London homes are flats, with windows high above the street. In a converted house or block, the lease generally says who is responsible for the windows, so it’s worth checking before booking.
We stand behind the work with a one-year guarantee, so you are covered after we have gone.

- First, we check where the water gets in.
- We remove the old sealant carefully.
- The joint is cleaned and degreased.
- We lay the new bead and tool it smooth.
- We check the finished joints and test with water where it’s safe.
Getting ready for the visit

City of London: your questions answered
I let a flat near London Cannon Street station. Can you help?
Yes. We work for landlords and agents as well as homeowners, and several properties can go on one quote. Just phone 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll give you a clear quote.
Is City of London in your area for glazing silicone?
Yes. We work across London and the South East, and City of London is part of that. Just phone 0345 464 0079 or drop us an email with a few details of the job, and we’ll give you a clear price.
Will it make a mess?
Tidy work is part of the job. We protect what’s around the joints, and the area is left clean when we finish.
Should I try DIY first?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. If it does not work out, we can redo it.
How long will you be here?
As a guide, most jobs take a few hours, depending on how many joints need doing. Larger jobs naturally take longer, and we will say how long yours will take.
What should I tell you?
A short description and the location, plus pictures if you have them. We’ll ask anything else we need to know.
Do you remove the old sealant?
Yes. All of the old material is cut out and the joint cleaned before applying anything new.
Do you guarantee glazing sealant work?
Every job comes with our 12-month guarantee, and we are fully insured.
How to look after the new joints
Good habits help new joints last longer. Our tips:
- Check the gutters above the glazing for debris
- Act on drips or damp patches early
- Squeegee the shower screen after each use
- Avoid strong solvents on or near the sealant
Use mild cleaners on and around the silicone. Strong solvents can soften or mark it.
Cracked glazing silicone means the joint has failed. Resealing now is a small job compared with fixing water damage later.
What we’re called out for in City of London
Shower screen silicone gets wet every day. Mould grows into the bead and the edges begin to peel.
Common reasons people contact us include:
- Leaking glazing joints on a rooflight
- Water tracking down the inner face of the glass
- Glazing silicone that has cracked or come away
- Stained, discoloured glazing silicone
For landlords with property near London Cannon Street station, leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies.
What your quote should include
- Are they insured?
- How long the guarantee is
- Whether they seal over old material or remove it
- What product goes in the joint
DIY versus a professional finish
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
