About our glazing silicone in Windmill Hill
Not every silicone suits glass. Our applicators use neutral-cure glazing silicone, which suits glass and most frame materials, finished with a neat, even bead. We work on rooflights, glass balustrade bases and glass-to-glass joints, and the jobs we see most are glazing silicone that has cracked or come away and water running down inside the glass.
Somewhere as small as Windmill Hill, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.
There’s a 12-month guarantee on every job, large or small.

Advice
DIY versus a professional finish
A DIY attempt does not rule out a professional job. We cut it out and start again.
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
Aftercare tips
Good habits help new joints last longer. A few tips:
- Do not leave a drip for the next storm
- Clear the conservatory gutters regularly
- Inspect the sealant on glazing annually
- Keep air moving in the conservatory
Look over the glazing joints every year or so. Catching a split early keeps the repair small.
If silicone on glass has cracked, water is already getting in. Renewing it early keeps it simple compared with fixing water damage later.
Windmill Hill homes and the weather
Historic houses like Layer Marney Tower (about 2.9 miles east) are a reminder that the area around Windmill Hill has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you live in an older home near Parish Church of All Saints (inworth), the joint between an old wall and a newer frame is usually the first place rain gets in. Schools such as Baynards Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s. If you let a flat or house near Kelvedon station, a shower screen or conservatory joint that leaks is easier to reseal while the property is empty.

What happens if it’s left?
Fixing a leaking screen early protects what’s underneath. Water from a failed joint can soak into the floor before it shows. Around Windmill 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 usually more efficient than separate visits, so it’s worth mentioning everything you’d like done. We will send you a clear quote for the lot.
