How we handle glazing silicone in The City
Glazing joints need a sealant made for glass. We use a neutral-cure glazing silicone, which suits glass and most frame materials, and we tool it to a neat, even finish. We work on rooflights, glass-to-glass joints and glass balustrade bases, and people most often call us about rooflight joints letting water in and water getting into a conservatory at the joints.
Outdoor sealant needs dry, clean surfaces, so work on frames around The City is planned for dry weather. Tell us about access to every side of the house, including upper-floor windows.
There’s a 12-month guarantee on every job, whatever its size.

Can I do it myself?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
What the job involves on each surface
Rooflights
A rooflight faces rain and sun from above. The sealant around the glass and frame wears faster than most.
Glass balustrade bases
The base of a glass balustrade is usually sealed. Failed sealant there lets water collect.
Common problems we fix in The City
Sunlight breaks sealant down and roof joints get the most sun. It goes brittle, cracks and stops sticking to the glass and frame.
Common reasons people contact us are:
- Leaks from the base of a shower screen
- Drips on the inside of a conservatory window
- Failed sealant around rooflight glass
- A quick top-up bead that didn’t last
For landlords with property near Saunderton station, leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies.
What your quote should include
- Whether they’re fully insured
- What happens if they find a problem under the old sealant
- How long the guarantee is
- Is the old sealant removed completely?
Keeping the joints in good condition
How long the joints last depends on use and care. Here’s what we suggest:
- Ventilate the conservatory to cut condensation
- Keep harsh solvents off the silicone
- Squeegee the shower screen after each use
- Check the silicone on glass every year or so
Gentle products are best near the sealant. Strong solvents can soften or mark it.
Cracked glazing silicone means the joint has failed. Resealing now is a small job, compared with repairing damaged frames or plaster.

Advice
Glazing silicone in The City: local notes
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. With historic houses such as West Wycombe Park House (about 2.7 miles south-east) nearby, there’s older building stock in the area around The City as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
For an older house near a landmark such as Church of St Paul, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. If you look after a building such as Radnage Church of England Primary School, the mastic around its windows and doors needs looking after like any other building’s.
