Glazing silicone in Aston, done properly
Not every silicone suits glass. Our applicators use neutral-cure glazing silicone, which suits glass and most frame materials, and we tool it to a neat, even finish. Typical jobs include glazing silicone that has cracked or come away and sealant that was laid over old silicone and failed, across shower screens, conservatory frames and glass-to-glass joints.
Homes in small places like Aston often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.
You get a one-year guarantee, the same in Aston as everywhere else we work.

Frames and glazing around Aston
With historic houses such as Greenlands (about 1 mile north-west) nearby, there’s older building stock in the area around Aston as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
In the older streets around Church of St Nicholas, the joint between an old wall and a newer frame is usually the first place rain gets in.
Aston is about 2 miles north-east of Henley-on-Thames, in Oxfordshire. Homes, rented property, offices and hotels in Aston can book us for glazing silicone, old or new, large or small.

What the job involves on each surface
Shower screens
A screen’s wall joint and tray joint are where leaks start. Both are resealed with anti-fungal silicone.
Conservatory frames
Exposed frame joints wear with the weather. A fresh bead seals them again.

Should I try it myself first?
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Signs you need glazing silicone in Aston
Glass and frames expand and contract with the temperature at different rates. Over years, that movement tears the silicone.
Any of these means the joints need attention:
- Shower screens leaking along the wall or tray
- Black or yellowed silicone on glass joints
- A quick top-up bead that didn’t last
- Failed sealant around rooflight glass
Rented homes near Henley-On-Thames station change hands often, and a shower screen or conservatory joint that leaks is easier to reseal while the property is empty.
Questions to ask before booking
- The length of the guarantee
- What the quote includes, VAT included or not
- Which colour the sealant will be
- How the surfaces are prepared before sealing
Looking after it afterwards
How long the joints last depends on use and care. We suggest:
- Wipe the screen down after showering
- Act on drips or damp patches early
- Inspect the sealant on glazing annually
- Avoid scraping close to the bead
Clear the conservatory gutters regularly so water doesn’t back up against the seals. Overflowing gutters can cause leaks of their own.
If silicone on glass has cracked, water is already getting in. Resealing now is a small job compared with fixing water damage later.
The process
The work is kept neat and contained to the area we’re working on, so you can get on with your day. Expect the work to take a few hours for most jobs, and we tell you how long to leave it before we go.

We bring what the job needs, so it can be finished in one trip where possible.
