Glazing & conservatory sealant in Covent Garden, Greater London
Glazing joints in Covent Garden need attention? We remove the old material, prepare the joints and seal them properly.
- Failed joints on frameless glass
- Glazing silicone that has cracked or come away
- Water escaping where a screen meets the wall
How we handle glazing silicone in Covent Garden
Our work covers conservatory joints, rooflights and glass panels plus shower screens and the bases of glass balustrades. The old sealant comes out, the joint is cleaned and new silicone goes in. If you are dealing with new silicone smeared over old sealant and water tracking down the inner face of the glass, we can help, on glass balustrade bases, conservatory frames and shower screens alike.
From mansion-block windows to modern glazing in new flats, London has every kind of frame. The mastic around them dries out and cracks with age, which is when draughts and damp patches appear in homes in Covent Garden.
Every job is covered by a one-year guarantee.

Covent Garden: your questions answered
Is parking an issue for glazing silicone in Covent Garden?
In much of London, parking needs planning: a visitor permit or a bay close to the door helps a lot, so mention what’s available when you book.
Can you do glazing silicone in Covent Garden?
Yes, Covent Garden is within the area we cover. We work across London and the South East. You can phone 0345 464 0079 or email us and tell us what needs doing.
Is a special sealant needed for glass?
A glazing-grade silicone is best. We use neutral-cure glazing silicone with anti-fungal products in bathrooms.
Should I try DIY first?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Can tenants book the work?
Of course. Ask your landlord first, and we can send them the quote if that helps.
Do you offer different sealant colours?
In most cases you can choose. We will explain which colours are available.
Does someone need to be in?
Access is agreed with you when the job is booked. Indoors, that normally means someone at home.
Do you reseal glass shower screens?
Yes. We remove the old sealant and reseal the wall and tray joints.
Covent Garden homes and the weather
Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Benjamin Franklin House (about 0.4 miles south) are a reminder that the area around Covent Garden has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
In the older streets around Crown Court Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. As a London address, Covent Garden can be tricky for parking: let us know about parking bays, permits or a driveway.

How it works
Once we’re on site, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours for most jobs. In Covent Garden, flats, stairs and shared entrances are part of the routine. Mention any building rules, key holders or managing agents when you book.
- We trace the leak and confirm it’s a sealant joint.
- 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.
Before we arrive
- Let us know about stairs, lifts or work at height
- Tell us about any water getting in
- Let us know about parking restrictions

Advice
How the job changes by surface
Conservatory frames
Exposed frame joints wear with the weather. A fresh bead seals them again.
Glass-to-glass joints
These joints are on show, so a straight, even finish matters.
Should I try it myself first?
A DIY attempt does not rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.

When it isn’t the sealant
It helps to know what we can’t do too:
- A sagging or failing conservatory roof
- Cracked or broken glass
- Leaks from the roof covering or flashing (a roofer’s job)
Not sure which it is? You can phone 0345 464 0079 or send us an email and we’ll tell you honestly before you book.
What we seal
- Shower screens
- Glass-to-frame joints
- Glass-to-glass joints
- Conservatory frames
- Rooflights
- Glass balustrade bases
Common problems we fix in Covent Garden
On shower screens, constant water and cleaning products wear silicone. Mould gets into it and the edges begin to peel.
The problems people generally mention when they call are:
- Shower screens leaking along the wall or tray
- Water running down inside the glass
- Glazing silicone that has cracked or come away
- Cracked silicone between glass panels
For site and facilities teams at buildings such as St Clement Danes CofE Primary School, larger buildings have plenty of frames, and the mastic around each one ages.
Questions to ask before you book
- When the joint can take water or movement
- What the quote includes, VAT included or not
- Which sealant they’ll use, and why
- How much experience the applicator has
What affects the quote in Covent Garden
The price is agreed before any work begins. It’s based on:
- Whether old sealant or filler has to be cut out
- The amount of work
- Working hours on commercial sites
- Whether there’s mould to deal with
Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs, along with when we can work on site. Call for a quick quote and we’ll go through it with you.
Helping us quote
Photos by email are helpful but not essential. Try to tell us:
- Any previous sealing or DIY work
- If it’s domestic, commercial or a hotel
- Pictures of the joints, sent by email
- Access, such as stairs, a lift or height
To get a quote, call 0345 464 0079 or send us an email and tell us where the job is and what the problem looks like. We will give you a clear quote before any work starts.
What happens if it’s left?
Glazing joints need a sealant made for the job. A general-purpose tube may not bond well or may react with the frame so we choose a glazing silicone instead. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and once it shows in Covent Garden, the repair is bigger than a sealant job.
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part.
What you get with us
- White, clear, grey or another colour, product permitting
- Neat joints and a tidy finish
- Anti-fungal sanitary silicone in wet areas
- More than 20 years in sealant work
