About our glazing silicone in Boars Hill
We renew glazing silicone on conservatories, rooflights and glass panels, as well as frameless shower screens and glass balustrade bases. The old sealant comes out, the joint is cleaned and new silicone goes in. Typical jobs include new silicone smeared over old sealant and failed joints on frameless glass, across glass-to-glass joints, shower screens and glass-to-frame joints.
Around Boars Hill, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.
Every job is covered by our 12-month guarantee.

Frames and glazing around Boars Hill
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. Historic houses like Appleton Manor (about 2.9 miles west) are a reminder that the area around Boars Hill 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.
If you let a flat or house near Oxford station, a shower screen or conservatory joint that leaks is easier to reseal while the property is empty. For an older house near a landmark such as Church of St Peter, frames set in older brick or stone need a sealant that suits the wall as well as the frame. Managing a site like Wootton St Peter's Church of England Primary School? Then larger buildings have plenty of frames, and the mastic around each one ages.

DIY versus a professional finish
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
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. All the old material has to come out first.
What happens if it’s left?
Leaks get worse, not better. Water can damage frames, walls, flooring and furniture so early action saves a bigger repair. Around Boars Hill, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Doing several joints on one visit is normally more efficient than separate visits, so tell us about everything that needs sealing. We will give you a clear price for the lot.

Where we work in Boars Hill
- Conservatory frames
- Glass-to-frame joints
- Glass balustrade bases
- Rooflights
- Glass-to-glass joints
- Shower screens
Different surfaces, different methods
Shower screens
Mouldy or lifting sealant on a screen leaks. A full reseal sorts it.
Glass balustrade bases
Glass balustrades sit in a channel that is often finished with sealant. Failed sealant there lets water collect.
For landlords and businesses
Whether it’s one flat or a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
Hotels need rooms back in use, so the work can be planned room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
Aftercare tips
Good habits help new joints last longer. A few tips:
- Ventilate the conservatory to cut condensation
- Stick to mild cleaners on glass
- Avoid scraping close to the bead
- Keep harsh solvents off the silicone
Avoid scraping near the new silicone when cleaning the glass. A soft cloth or sponge is best.
Do not leave lifting or mouldy silicone on glazing. Peeling silicone lets water in behind and the leak gets worse.
