- Leaks from the roof covering or flashing (a roofer’s job)
- Frames that have decayed or split

Glazing silicone for homes and businesses in Mongewell
Across Mongewell, we reseal glazing joints in homes, offices and hotels. From conservatories to shower screens, it’s the same careful method. We work on shower screens, glass-to-frame joints and glass balustrade bases, and the jobs we see most are water getting into a conservatory at the joints and water escaping where a screen meets the wall.
Homes in small places like Mongewell 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.
All of our work is guaranteed for twelve months, in Mongewell and everywhere else we cover.

Different surfaces, different methods
Conservatory frames
Frame-to-wall joints on a conservatory move with the weather. They’re resealed with a suitable sealant.
Glass-to-frame joints
Glass-to-frame joints need a sealant that bonds to both. We choose a product that suits both.

What else we do in Mongewell
Can I do it myself?
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so just mention it when you contact us.
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.
Looking after it afterwards
Simple care keeps the joints in good condition. We recommend:
- Keep harsh solvents off the silicone
- Wipe the screen down after showering
- Keep conservatory gutters clear of leaves
- Avoid scraping close to the bead
On shower screens, wipe or squeegee after use and keep the room ventilated. That slows mould growth on the bead.
Damp patches, drips and condensation along a joint are worth checking. It may be sealant, or something else, and we will tell you which.
Your questions about glazing silicone in Mongewell
Will you come out to Mongewell?
Yes, Mongewell is covered. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Can you help a landlord with a rental near Cholsey station?
Yes. We work for landlords and agents as well as householders. You can phone 0345 464 0079 or drop us an email with the details for a clear quote.
Can I add another job to the visit?
Yes. Tell us about everything you’d like done and you’ll get one quote.
Do you fit new glass or sealed units?
No. We renew the sealant. Glass and sealed units need a glazier.
What do you need from me for a quote?
Where the job is, what the problem is and roughly how big it is. If you can, email a few pictures.
Is it enough to run a bead over the old sealant?
Many leaks we see come from exactly that. We remove the old silicone, clean the joint and reseal.
Should I try DIY first?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
Can you fix a leaking conservatory?
Yes, when the leak is a failed sealant joint. If it’s a broken panel, failed unit or roof problem, we will tell you.
Mongewell homes and the weather
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. With historic houses such as Brightwell Manor (about 2.6 miles north-west) nearby, there’s older building stock in the area around Mongewell 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’s traditional sand mastic.
If you live in an older home near St Mary's Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame. Rented homes near Cholsey station change hands often, and glazing joints are worth checking at the end of a tenancy, before a small leak grows.

What we’re called out for in Mongewell
Silicone won’t bond to a dirty surface. If the glass and frame weren’t cleaned properly the sealant may lift within a few years.
These are the problems we’re asked about most:
- Silicone pulling away from the glass
- A quick top-up bead that didn’t last
- Stained, discoloured glazing silicone
- Shower screens leaking along the wall or tray
Managing a site like Crowmarsh Gifford Church of England School? Then larger buildings have plenty of frames, and the mastic around each one ages.
