Different surfaces, different methods
Glass-to-frame joints
The sealant must stick to glass and frame alike. We use a glazing silicone suited to each.
Glass-to-glass joints
Glass-to-glass joints depend entirely on the sealant. It must be clean, neat and well bonded.
Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Run a squeegee over the glass when you are done
- Keep scrapers and blades away from the silicone
- Stick to mild cleaners on glass
- Keep conservatory gutters clear of leaves
Check the joints once a year. Spotting a crack early means a simpler fix, before water gets in.
A leaking shower screen may not show at first. It can damage the floor or the ceiling below before you spot it.

What glazing silicone looks like in Newyears Green
Historic houses like Ickenham Hall (about 1.5 miles south-east) are a reminder that the area around Newyears Green has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. 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.
Schools such as Whiteheath Infant and Nursery School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s. Ickenham Hall, about 1.5 miles south-east, is one of the historic houses in the wider area around Newyears Green, and older homes nearby need a sealant that suits their walls.

Why it’s worth doing now in Newyears Green
Silicone around glazing needs the right product. General-purpose sealant from a DIY shop may not suit glass or the frame, so we use neutral-cure glazing silicone. Where a wall is exposed, as many are in small places like Newyears Green, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
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. Your quote takes all of that into account.
