About our glazing silicone in Charlton-on-Otmoor
A frameless shower screen depends on its silicone. Leaks normally come from the wall joint or the tray joint, and we reseal both. We work on shower screens, glass-to-frame joints and glass balustrade bases, and people most often call us about water getting into a conservatory at the joints and water escaping where a screen meets the wall.
Homes in small places like Charlton-on-Otmoor 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.
Each job carries a 12-month guarantee.

A screen’s wall joint and tray joint are where leaks start. We reseal both with anti-fungal silicone.
Conservatory frames
Conservatory frame joints are a common source of leaks. We cut out the old sealant and reseal.

What else we do in Charlton-on-Otmoor
Why act early in Charlton-on-Otmoor
Leaks get worse, not better. Left, water can mark floors, damage plaster and rot timber so early action saves a bigger repair. In a small place like Charlton-on-Otmoor, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.

Windows and doors in Charlton-on-Otmoor
Historic houses like Boarstall Tower (about 4 miles east) are a reminder that the area around Charlton-on-Otmoor has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. 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.
For an older house near a landmark such as Church of St Mary the Virgin, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. If you look after a building such as Charlton-on-Otmoor Church of England Primary School, its window and door frames need their mastic kept sound, just like a home’s.

Can I do it myself?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
If you’re 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.
