About our glazing silicone in Sydenham
Not every silicone suits glass. We use a neutral-cure glazing silicone that’s suited to glass and the frame, finished with a neat, even bead. We work on glass-to-frame joints, conservatory frames and glass balustrade bases, and people most often call us about drips on the inside of a conservatory window and leaking glazing joints on a rooflight.
Somewhere as small as Sydenham, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.
Every job comes with our one-year guarantee, wherever you are in Oxfordshire.

Frames and glazing around Sydenham
Historic houses like Adwell House (about 2.4 miles south-west) are a reminder that the area around Sydenham 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, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
In the older streets around Church of St Mary, the joint between an old wall and a newer frame is usually the first place rain gets in. Rented homes near Haddenham & Thame Parkway station change hands often, and leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies.

Keeping the joints in good condition
How long the joints last depends on use and care. Here’s what we suggest:
- Avoid scraping close to the bead
- Squeegee the shower screen after each use
- Inspect the sealant on glazing annually
- Open vents or windows to let moisture out
Keep the new joints dry for as long as we advise. After that, clean glass with a mild cleaner.
A leaking shower screen may not show at first. It can damage the floor or the ceiling below long before you see it.
Sydenham: your questions answered
Will you come out to Sydenham?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Can you help a landlord with a rental near Haddenham & Thame Parkway station?
Yes, landlords and agents are among the people we work for. Just call 0345 464 0079 or drop us an email with the address and what needs doing, and we will send you a clear quote.
What do you need from me for a quote?
A short description and the location, with pictures by email if possible. If we need more, we will ask.
What sealant do you use?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference, and we will explain our choice.
What guarantee do I get?
Every job comes with our 12-month guarantee.
Is there any odour?
Sometimes, a little. It fades as the sealant cures.
Do you do commercial work?
Yes. We work in offices, washrooms, hotels and other commercial premises, as well as homes. Working times can be discussed when we quote.
Will it make a mess?
No. The area is protected while we work and cleaned up afterwards.
What else we do in Sydenham
DIY versus a professional finish
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
When it isn’t the sealant
It helps to know what we can’t do:
- Water coming through the roof rather than a sealant joint
- Frames that have decayed or split
- Cracked or broken glass
If you’re not sure, just call 0345 464 0079 or email us and we will give you a straight answer.

- We cut out the failed silicone, taking care of the glass and frame.
- The glass and frame are cleaned and degreased.

- The finished joints are checked and, where it’s safe, tested with water.
