Charing Cross Glazing Silicone
Glazing silicone across Charing Cross and nearby, with every bit of old sealant taken out first and a 12-month guarantee.
- Stained, discoloured glazing silicone
- Conservatory leaks at frame and glazing joints
- Shower screens leaking along the wall or tray
What happens if it’s left?
Resealing can’t fix a failed unit or a cracked panel. We’ll tell you that rather than seal it anyway, so you can call the right trade. In a flat in Charing Cross, failed sealant seldom stays inside your own four walls: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
Doing several joints on one visit is usually more efficient than separate visits. We will send you a clear quote for the lot.
Why choose Mr Mastic in Charing Cross
- One-year guarantee on every job
- Any old sealant cut out fully, not covered over
- You choose the colour before work begins
- We leave the area clean and tidy

How we handle glazing silicone in Charing Cross
Glazing silicone that has yellowed, blackened or come away spoils the look and lets water in. It comes off cleanly, without marking the glass before the new bead goes in. If you have failed joints on frameless glass and split or lifting silicone on glass, we can help, on glass-to-frame joints, shower screens and glass balustrade bases alike.
London’s Victorian and Edwardian terraces were built with timber sash windows, and many still have them or their replacements. Either way, the mastic between frame and brickwork is what stops draughts and rain getting in, in Charing Cross as anywhere.
Our work is backed for twelve months.

Which products do you use?

Will you leave a mess?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
How the visit works
On the day, we look over the joints with you first. We protect the surfaces around the joints before work begins. Most jobs take anything from an hour or two to most of a day, depending on the size of the job. In a London area like Charing Cross, 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 check where the water gets in.
- The failed silicone is cut out without marking the glass or frame.
- We clean the glass and frame so the new silicone bonds.
- A neutral-cure glazing silicone is applied and tooled.
- Each joint is checked and, where possible, water-tested.
Preparing for the visit
- On commercial sites, let us know about site rules
- Let us know about earlier repairs to the joints
- Tell us about access, such as stairs, a lift or high-level joints

Advice
Honest limits
Before you book, it’s worth knowing the limits:
- Rotten or badly damaged frames
- Water coming through the roof rather than a sealant joint
- Glass that needs replacing
If in doubt, phone 0345 464 0079 or email us and we will say what we think.
What we seal
- Glass-to-frame joints
- Rooflights
- Conservatory frames
- Shower screens
- Glass balustrade bases
- Glass-to-glass joints
Do you need glazing silicone in Charing Cross?
New silicone over old silicone will not bond. Plenty of leaks come from a quick top-up over the old bead, and water gets between the layers.
These are the problems we are asked about most:
- Rooflight joints letting water in
- Split or lifting silicone on glass
- Cracked silicone between glass panels
- Water escaping where a screen meets the wall
For site and facilities teams at buildings such as Soho Parish CofE Primary School, the mastic around its windows and doors needs looking after like any other building’s.

How to look after the new joints
Aftercare is simple, and it makes a real difference:
- Keep harsh solvents off the silicone
- Act on drips or damp patches early
- Keep air moving in the conservatory
- Inspect the sealant on glazing annually
Use mild cleaners on and around the silicone. Strong solvents can soften or mark it.
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.
Should I try it myself first?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
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 fails, we can still redo it.
What affects the quote in Charing Cross
There’s no set price list. The quote depends on:
- Which sealant suits the joint
- Whether the work is at height
- The size of the job
- Any mould that needs treating
Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs, plus any working-time requirements on site. Ask us for a quote and we will explain what it covers.
What to tell us for a quote
When you call or email, these details help:
- What the problem is, such as mould, gaps, leaks or cracking
- A few pictures by email, if you can
- If it’s domestic, commercial or a hotel
- Any previous sealing or DIY work
Quotes start with a quick conversation. Describe the problem, the location and the size of the job, and we will talk you through what we’d do. Whenever you are ready, call 0345 464 0079 or send us an email.
Glazing silicone in Charing Cross: local notes
With historic houses such as Benjamin Franklin House (about 0.1 miles east) nearby, there’s older building stock in the area around Charing Cross as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Charing Cross is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book. Homes close to St Martin-in-the-Fields include some older properties, and the joint between an old wall and a newer frame is normally the first place rain gets in.
