Glazing & conservatory sealant in Northbourne, Kent
We cover Northbourne for glazing silicone for conservatories, rooflights, glass panels and shower screens. Old sealant removed completely, joints prepared properly and a 12-month guarantee.
- Silicone pulling away from the glass
- Leaks where conservatory glass meets the frame
- Glass-to-glass joints that have split
DIY versus a professional finish
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
Glazing silicone in Northbourne
We renew glazing silicone on conservatories, rooflights and glass panels, as well as frameless shower screens and glass balustrade bases. The old sealant comes out, the joint is cleaned and new silicone goes in. We work on glass-to-glass joints, conservatory frames and rooflights, and common reasons people get in touch are failed sealant around rooflight glass and black or yellowed silicone on glass joints.
Homes in small places like Northbourne often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.
We stand behind the work with a one-year guarantee, so you’re covered after we have gone.

Windows and doors in Northbourne
The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Walmer Castle (about 3 miles south-east) are a reminder that the area around Northbourne has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
Managing a site like Northbourne Church of England Primary School? Then the mastic around its windows and doors needs looking after like any other building’s. For landlords with property near Walmer station, glazing joints are worth checking at the end of a tenancy, before a small leak grows.

FAQs for Northbourne
Do you cover Northbourne for glazing silicone?
Yes. Our work covers London and the South East, and Northbourne is part of that. Just ring 0345 464 0079 or send us an email with a few details of the job, and we’ll send you a clear quote.
Do you work for landlords with property near Walmer station?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. You can phone 0345 464 0079 or drop us an email with the details for a clear quote.
Can a conservatory leak be sealed?
If the water is coming in through failed sealant joints, yes. If the cause is the roof, a panel or a unit, we will say so.
Can I add another job to the visit?
Yes, and it often makes sense. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
Is it enough to run a bead over the old sealant?
A top-up rarely holds. Fresh silicone will not bond to cured silicone so we take it all out and start clean.
Is it worth trying it myself?
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.
What does glazing silicone cost?
We don’t publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. You’ll get a clear quote before work begins.
Will you leave a mess?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
Do you need glazing silicone in Northbourne?
Sealant laid over old sealant doesn’t last. Plenty of leaks come from a quick top-up over the old bead leaving a path for water.
Any of these means the joints need attention:
- A quick top-up bead that didn’t last
- Water getting into a conservatory at the joints
- Glazing silicone that has cracked or come away
- Leaking glazing joints on a rooflight
For an older house near a landmark such as Church of St Augustine, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Why it’s worth doing now in Northbourne
Replacing windows or a shower screen isn’t needed for a failed joint. Sound glass and frames generally just need resealing, and we will tell you if that’s not the case. Around Northbourne, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs, plus any working-time requirements on site. Ask us for a quote and we will go through it with you.
Why book with us
- 20+ years of sealant experience
- Neat joints and a tidy finish
- A choice of colours where the product allows
- An ARBOMaster approved applicator

Honest limits
To be straight with you, some problems need a different trade:
- Frames that have decayed or split
- A sagging or failing conservatory roof
- Misting between the panes of a double-glazed unit (a failed unit for a glazier)
