Glazing silicone for homes and businesses in Hackbridge
Cracked, stained or lifting silicone on glass looks poor and can leak. We remove it without scratching the glass or frame before the new bead goes in. Common call-outs are for drips on the inside of a conservatory window and mouldy sealant around glass panels, across rooflights, glass-to-glass joints and glass balustrade bases.
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, letting in draughts and water.
Every job is covered by a one-year guarantee.

What affects the cost of glazing silicone
There’s no set price list, because jobs vary so much. What we look at:
- Any mould that needs treating
- The size of the job
- When we can work, for business premises
- How much old sealant there is and how hard it is to remove
What it costs depends on the size of the job, how hard the old material is to remove and access to the work. We give a clear quote before any work starts.
Helping us quote
Photos help, but a description is a good start. Please mention:
- Whether it’s a home or a business
- Whether it has been sealed before
- Roughly how big the job is
- Where the property is
A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is.
What happens if it’s left?
Topping up old silicone can look like a fix, but silicone doesn’t stick to silicone, and the leak normally returns. A proper reseal is the lasting answer. Damp from a failed joint spreads quietly in older London brickwork and timber, and once it shows in Hackbridge, the repair is bigger than a sealant job.
The cost reflects the work involved, not a rough estimate. That is why we ask a few questions first and send you a clear quote before any work starts.
Why us?
- Colour picked to suit the job
- Anti-fungal silicone where joints get wet

What else we do in Hackbridge
Hackbridge homes and the weather
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. With historic houses such as Southside House (about 3.6 miles west) nearby, there’s older building stock in the area around Hackbridge 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.
Hackbridge is in London, so parking needs planning: let us know about parking bays, permits or a driveway. For landlords with property near Mitcham Eastfields station, leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies. In the older streets around St. Mark's Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

What we cannot put right
Honest advice matters more to us than a booking, so here’s what new sealant won’t do:
- A sagging or failing conservatory roof
- A broken pane or roof panel
- A frame that needs repairing or replacing
Not sure which it is? You can call 0345 464 0079 or email us and we will tell you honestly before you book.
Where we work in Hackbridge
- Conservatory frames
- Glass balustrade bases
- Shower screens
- Glass-to-glass joints
- Glass-to-frame joints
- Rooflights
Looking after it afterwards
Looking after new joints is easy, and it makes a real difference:
- Open vents or windows to let moisture out
- Stick to mild cleaners on glass
- Keep conservatory gutters clear of leaves
- Act on drips or damp patches early
Look over the glazing joints every year or so. Spotting a crack early means a simpler fix, before water gets in.
Damp patches, drips and condensation along a joint are worth checking. It may be sealant, or something else and we’ll find out which.
What the job involves on each surface
Rooflights
A rooflight faces rain and sun from above. The sealant around the glass and frame wears faster than most.
Conservatory frames
Conservatory frame joints are a common source of leaks. We remove the failed sealant and renew it.
