- Failed joints on frameless glass
- Silicone pulling away from the glass
Glazing silicone in Heronsgate
Frameless shower screens rely on sealant to keep water in. The joint down the wall and the one along the tray are common leak points, and we reseal both. If you have split or lifting silicone on glass and failed joints on frameless glass, we can put it right, on shower screens, conservatory frames and glass balustrade bases alike.
Around Heronsgate, 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.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

What glazing silicone looks like in Heronsgate
The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. With historic houses such as Chenies Manor House (about 2.4 miles north) nearby, there’s older building stock in the area around Heronsgate as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
For an older house near a landmark such as St John, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. Schools such as Chorleywood Primary School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.

What to look for in a quote
- What insurance they hold
- What the quote includes, VAT included or not
- Which sealant they’ll use, and why
- How the colour is chosen
Different surfaces, different methods
Rooflights
Rooflights get the full force of the weather. The sealant around the glass and frame wears faster than most.
Shower screens
Black or peeling silicone on a screen lets water out. Cutting it out and resealing fixes it.
Looking after it afterwards
Simple care keeps the joints in good condition. We recommend:
- Wipe the screen down after showering
- Clean glass with a mild cleaner and a soft cloth
- Avoid strong solvents on or near the sealant
- Check the silicone on glass every year or so
Look over the glazing joints every year or so. Catching a split early keeps the repair small.
Act on black or lifting silicone early. Peeling silicone lets water in behind and the leak gets worse.
Leave it or put it right?
A leaking joint will not fix itself. Water can damage frames, walls, flooring and furniture, so it pays to deal with it early. Where a wall is exposed, as many are in small places like Heronsgate, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
