Different surfaces, different methods
Glass balustrade bases
The base of a glass balustrade is generally sealed. Failed sealant there lets water collect.
Rooflights
We reseal the glazing joints on rooflights. Leaks from the roof itself need a roofer.
Glazing silicone in Weston-on-the-Green
Sealant on glazing doesn’t last for ever. Sun, rain and movement wear it down, and once it cracks, water follows. Renewing it keeps glazing joints doing their job. We work on glass-to-glass joints, glass-to-frame joints and conservatory frames, and the jobs we see most are water running down inside the glass and stained, discoloured glazing silicone.
Homes in small places like Weston-on-the-Green often stand in the open, with little to shelter their windows from wind and rain. That exposure dries out and cracks the mastic around frames and sills faster.
Every job is covered by our 12-month guarantee, wherever you are in Oxfordshire.

Frames and glazing around Weston-on-the-Green
Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you let a flat or house near Islip station, leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies. Homes close to Church of St Mary include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. Our tips:
- Wipe the screen down after showering
- Use gentle products around the joints
- Act on drips or damp patches early
- Clear the conservatory gutters regularly
Keep the new joints dry for as long as we advise so the silicone can set properly. From then on, a mild glass cleaner is all it needs.
Drips or damp near a glazing joint shouldn’t be ignored. It may be sealant, or something else, and we will tell you which.
DIY versus a professional finish
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
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.
How it works
Every visit runs the same way: we check the joints, mask and protect the surrounding surfaces, carry out the job and clear up. Most jobs take anything from an hour or two to most of a day, depending on the size of the job. In a small place like Weston-on-the-Green, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- First, we trace the leak and check it’s coming through a sealant joint.
- The old sealant is removed from the glass and frame without scratching them.
- We clean the joint with a solvent that suits the glass and frame.
- New glazing silicone goes in and is tooled to a neat finish.
- We check the joints and, where safe, run water over them.
Preparing for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Clear the area around the work
- Where the joints are inside, avoid wetting them before we arrive
