Glazing silicone in Swinford
Not every silicone suits glass. We use a neutral-cure glazing silicone that’s suited to glass and the frame, and we tool it to a neat, even finish. If you have rooflight joints letting water in and shower screens leaking along the wall or tray, we can put it right, on glass-to-glass joints, shower screens and conservatory frames alike.
Somewhere as small as Swinford, 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.
We stand behind the work with a one-year guarantee.

How to look after the new joints
Simple care keeps the joints in good condition. We recommend:
- Keep harsh solvents off the silicone
- Open vents or windows to let moisture out
- Squeegee the shower screen after each use
- Look over the glazing joints once a year
Look over the glazing joints every year or so. Catching a split early keeps the repair small, before water gets in.
Shower screen leaks can go unnoticed. Water can soak into the floor or reach the room below before you spot it.
What glazing silicone looks like in Swinford
Historic houses like Appleton Manor (about 4.4 miles south) are a reminder that the area around Swinford 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 is traditional sand mastic. London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Letting a property close to Hanborough station? Then glazing joints are worth checking at the end of a tenancy, before a small leak grows. For an older house near a landmark such as Church of St Leonard, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. Managing a site like Eynsham Community Primary School? Then the mastic around its windows and doors needs looking after like any other building’s.

Will resealing stop my conservatory leaking?
In many cases, as long as sealant is the cause. We trace the leak first before any sealing.
What sealant do you use on glazing?
Glass needs a sealant made for glazing. Ours is a neutral-cure glazing silicone with anti-fungal products in bathrooms.
Will it make a mess?
We keep the work tidy. We protect what’s around the joints, and we clear up when we are done.
How do I get a quote for glazing silicone in Swinford?
Every job is different, so each one gets its own quote. To get one, call 0345 464 0079 or email us with a short description of the job.
Is it worth trying it myself?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Do the sealants smell?
Some sealants have a smell while they cure, which fades as it sets. Ventilation helps.
DIY sealant or a professional job?
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
What happens if it’s left?
Replacing a conservatory roof is major work. If the leak is a failed sealant joint renewing the joint is the simpler fix. If it’s the roof itself, we’ll tell you. Where a wall is exposed, as many are in small places like Swinford, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we will explain the quote if you ask.
