Surface by surface
Glass balustrade bases
Glass balustrades sit in a channel that is often finished with sealant. When it fails, water can sit in the channel.
Shower screens
A screen’s wall joint and tray joint are where leaks start. We reseal both with anti-fungal silicone.
About our glazing silicone in Horn Hill
We do not replace glass and a misted double-glazed unit needs a glazier. Our work is the sealant joints and that’s often where the water gets in. If you have glass-to-glass joints that have split and stained, discoloured glazing silicone, we can put it right, on shower screens, glass-to-glass joints and glass balustrade bases alike.
In a village or hamlet like Horn Hill, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.
Big or small, you get the same one-year guarantee.

Aftercare tips
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Avoid strong solvents on or near the sealant
- Do not leave a drip for the next storm
- Inspect the sealant on glazing annually
- Clear the conservatory gutters regularly
Check the joints once a year. Spotting a crack early means a simpler fix, before water gets in.
Act on black or lifting silicone early. Once it starts to peel, water gets behind it and the problem grows.

Quotes for glazing silicone in Horn Hill
The quote reflects the job in front of us. We look at:
- Which sealant suits the joint
- Mould in or behind the old joints
- How many areas need sealing
- How easy the joints are to reach
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. We take all of that into account in your quote.

Common problems we fix in Horn Hill
Dirt and grease stop silicone sticking. If the glass and frame weren’t cleaned properly the sealant may lift within a few years.
The most common problems we see are:
- Drips on the inside of a conservatory window
- Failed joints on frameless glass
- Leaking glazing joints on a rooflight
- Water getting into a conservatory at the joints
Homes close to St Paul's include some older properties, and the joint between an old wall and a newer frame is generally the first place rain gets in.

Related advice
Why act early in Horn Hill
If the problem is a misted unit or a broken panel, sealant won’t help. We’ll tell you that rather than seal it anyway, so you can call the right trade. Around Horn Hill, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
What you pay reflects the work, not a rough estimate. That’s why we ask a few questions first.

I let a flat near Chorleywood station. Can you help?
Yes, rental work is part of what we do. You can call 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before work begins.
Can you match the sealant colour?
In most cases you can choose. We will explain which colours are available and agree one before we start.
Are you insured?
Yes. Full insurance covers our work, and we can confirm the details when we quote.
Do you seal glass balustrade bases?
Yes. The old sealant is removed and the joint resealed using a sealant that suits the materials.
How much does glazing silicone cost in Horn Hill?
There’s no set price, as it depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
What guarantee do I get?
All our work has a 12-month guarantee, and we’re fully insured.
Do you take out the old sealant first?
Yes, every time. New sealant won’t bond properly to old, so any old material comes out before anything new goes in.
When it is not the sealant
To be straight with you, there are a few things sealant will not fix:
- Misting between the panes of a double-glazed unit (a failed unit for a glazier)
- A sagging or failing conservatory roof
- A broken pane or roof panel
If in doubt, phone 0345 464 0079 or send us an email and we’ll say what we think before booking.

Frames and glazing around Horn Hill
Historic houses like Chenies Manor House (about 3.6 miles north) are a reminder that the area around Horn Hill 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. The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For site and facilities teams at buildings such as Maple Cross Junior Mixed Infant and Nursery School, larger buildings have plenty of frames, and the mastic around each one ages. Rented homes near Chorleywood station change hands often, and glazing joints are worth checking at the end of a tenancy, before a small leak grows.
