How we handle glazing silicone in Harvel
Glass replacement is not something we do and a misted double-glazed unit needs a glazier. Our work is the sealant joints and that’s often where the water gets in. We work on glass-to-glass joints, glass-to-frame joints and shower screens, and common reasons people get in touch are failed joints on frameless glass and leaks where conservatory glass meets the frame.
Somewhere as small as Harvel, older homes often have timber frames set in stone or brickwork. Older buildings like these don’t always suit modern silicone, and sometimes a traditional sand mastic is the better choice.
Big or small, it’s backed by our 12-month guarantee in Harvel and across Kent.

What we’re called out for in Harvel
UV light ages silicone, especially on conservatory roofs. Old silicone hardens, cracks and loses its grip to the glass and frame.
Any of these means the joints need attention:
- Failed joints on frameless glass
- Drips on the inside of a conservatory window
- Sealant that was laid over old silicone and failed
- Rooflight joints letting water in
Letting a property close to Sole Street station? Then glazing joints are worth checking at the end of a tenancy, before a small leak grows.

How the job changes by surface
Shower screens
Frameless screens rely on silicone at the base and wall. We renew it without marking the glass.
Conservatory frames
Conservatory frame joints are a common source of leaks. We remove the failed sealant and renew it.
What we do, step by step
On the day, there’s very little for you to do. Show us the job and we will take it from there. The work itself takes a few hours, depending on how many joints need doing, including the tidy-up. Somewhere like Harvel needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- First, we check where the water gets in.
- The failed silicone is cut out without marking the glass or frame.
- We clean the glass and frame so the new silicone bonds.
- We lay the new bead and tool it smooth.
- Each joint is checked and, where possible, water-tested.
Preparing for the visit
- Clear the area around the work
- Tell us about access, such as stairs, a lift or high-level joints
- Mention any parking rules near the property

How we quote for glazing silicone
There’s no set price list, because jobs vary so much. What we look at:
- Access and height
- How many areas need sealing
- Any working-time requirements on site
- The number and length of the joints
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.
Helping us quote
To help us quote quickly, let us know:
- Whether it has been sealed before
- Any access issues, like height or stairs
- Where the job is, and your postcode
- Roughly how big the job is

Landlords, agents and businesses in Harvel
Whether it’s one flat or a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
In hotels, rooms out of use cost money, so the work can be planned room by room. We have worked in hotels as well as homes and businesses.
Can I do it myself?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
What glazing silicone looks like in Harvel
Historic houses like Cobham College (about 3.4 miles north-east) are a reminder that the area around Harvel 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. London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
In the older streets around Church of Our Lady of the Meadow, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. Schools such as Culverstone Green Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.
