Glazing silicone for homes and businesses in Holborn
Glass, frames and walls all move at different rates, so the sealant between them does a lot of work. When it cracks or lets go, water gets in. We replace it with a glazing silicone that suits the glass and frame. We work on conservatory frames, glass-to-glass joints and glass-to-frame joints, and people most often call us about mouldy sealant around glass panels and water running down inside the glass.
London has a lot of flats and conversions, where windows are often on upper floors. Who looks after the outside of the frames can depend on the lease, so check that first, and access in Holborn is something to talk through when you book.
A one-year guarantee comes as standard.

What glazing silicone looks like in Holborn
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. In London conversions and blocks, the lease decides who is responsible for the frames, so check that before booking.
Homes close to St Alban's Church include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. For site and facilities teams at buildings such as St Alban's Church of England Primary School, the mastic around its windows and doors needs looking after like any other building’s.
Holborn is about 2 miles north-west of London, in Greater London. Jobs in Holborn get the same care as everywhere else we work: old sealant removed completely, careful preparation and a 12-month guarantee. Holborn is one of 764 places in Greater London where we work.

We work in homes and buildings around The Yorkshire Grey pub, British Library of Political and Economic Science and City Academy. You will also find Elizabeth Garrett Anderson School (0.9 miles north) and Lincoln's Inn Fields (less than half a mile south-west). There’s a railway station in Holborn itself: Farringdon station.

Keeping the joints in good condition
Aftercare is simple:
- Wipe the screen down after showering
- Ventilate the conservatory to cut condensation
- Clear the conservatory gutters regularly
- Look over the glazing joints once a year
Keep conservatory gutters clear, so water drains away from the joints. Overflowing gutters can cause leaks of their own.
Damp patches, drips and condensation along a joint are worth checking. The cause may be sealant or another part and we’ll find out which.

I let a flat near Farringdon station. Can you help?

Where are you based?

Are you fully insured?
Yes. Full insurance covers our work.
What guarantee do I get?
Every job comes with our one-year guarantee, and we are fully insured.
How do I get a quote for glazing silicone in Holborn?
We do not publish prices, because the cost depends on the job: its size, the old material, access and the product needed. You’ll get a clear quote before we start.
How long before the joint can be used?
Most sealants are touch-dry well before they’re fully cured. We will give you the cure time for the product we used.
Will there be a smell?
Some sealants have a smell while they cure, but it fades. Opening a window helps.
Can I do it myself?
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.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
When something else is needed
Sealant isn’t the answer to every problem, and we’ll tell you before work begins. Sealant won’t put right:
- A frame that needs repairing or replacing
- Water coming through the roof rather than a sealant joint
- Misting between the panes of a double-glazed unit (a failed unit for a glazier)
Not sure which it is? You can phone 0345 464 0079 or email us and we’ll tell you honestly before you book.

What affects the cost of glazing silicone
Some jobs are bigger than they look, and some smaller. What affects the quote:
- Whether old sealant or filler has to be cut out
- Any working-time requirements on site
- The number and length of the joints
- The product the joint needs
The cost depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. You’ll have a clear quote before any work starts, so you know where you stand.

Photos help, but a description is a good start. Please mention:

- Any access issues, like height or stairs
