Glazing silicone in Stanton St John, done properly
Frameless shower screens rely on sealant to keep water in. Leaks normally come from the wall joint or the tray joint, and we reseal both. Common call-outs are for water tracking down the inner face of the glass and water getting into a conservatory at the joints, across shower screens, rooflights and glass-to-glass joints.
Outdoor sealant needs dry, clean surfaces, so work on frames around Stanton St John is planned for dry weather. Tell us about access to every side of the house, including upper-floor windows.
The work is covered for a year after we finish. If there’s a problem with it, please ring 0345 464 0079 or email us.

Common problems we fix in Stanton St John
Shower screen silicone gets wet every day. Mould grows into the bead and the edges begin to peel.
It’s worth asking for a quote if you see:
- Leaking glazing joints on a rooflight
- Shower screens leaking along the wall or tray
- Split or lifting silicone on glass
- Water getting into a conservatory at the joints
For site and facilities teams at buildings such as Wheatley Park School, the mastic around its windows and doors needs looking after like any other building’s.

Can I do it myself?
If you are set on DIY, put the effort into 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.
Some sealant jobs are within reach of a careful DIYer, 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.

Advice
Work for landlords, hotels and businesses
Housing providers, facilities teams and property managers book us too. Several sites can be quoted together, and we are fully insured.
Hotels need rooms back in use, so we plan the work room by room. Hotel work is part of what we do, alongside homes and businesses.
Looking after it afterwards
Good habits help new joints last longer. A few tips:
- Keep scrapers and blades away from the silicone
- Inspect the sealant on glazing annually
- Don’t leave a drip for the next storm
- Keep air moving in the conservatory
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.
Shower screen leaks can go unnoticed. It can damage the floor or the ceiling below before you spot it.
Why it’s worth doing now in Stanton St John
Leaks get worse, not better. Water can damage frames, walls, flooring and furniture so early action saves a bigger repair. Where a wall is exposed, as many are in small places like Stanton St John, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
There are no prices on our website, because each job is priced on what it involves. Call for a quick quote.

Glazing silicone in Stanton St John: local notes
London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Holywell Manor (about 4 miles south-west) are a reminder that the area around Stanton St John 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.
Homes close to Church of St John the Baptist include some older properties, and the joint between an old wall and a newer frame is generally the first place rain gets in. Letting a property close to Islip station? Then a shower screen or conservatory joint that leaks is easier to reseal while the property is empty.
