About our glazing silicone in Thorley Street
Glazing silicone is a maintenance item. Sun, rain and movement wear it down, and once it cracks, water follows. Resealing puts that right. We work on glass balustrade bases, glass-to-frame joints and glass-to-glass joints, and people most often call us about shower screens leaking along the wall or tray and split or lifting silicone on glass.
Somewhere as small as Thorley Street, 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.
All of our work is guaranteed for twelve months.

Leave it or put it right?
You do not need new glazing because the sealant has gone. Sound glass and frames generally just need resealing. Around Thorley Street, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.

What we’re called out for in Thorley Street
Heat and cold make glass and frames move, and they don’t move by the same amount. In time, the sealant splits or pulls away.
It’s worth asking for a quote if you see:
- Glazing silicone that has cracked or come away
- Glass-to-glass joints that have split
- Leaks from the base of a shower screen
- Water tracking down the inner face of the glass
For landlords with property near Bishops Stortford station, glazing joints are worth checking at the end of a tenancy, before a small leak grows.

FAQs for Thorley Street
Do you work for landlords with property near Bishops Stortford station?
Yes. We work for landlords and letting agents as well as householders. Just ring 0345 464 0079 or email us with the address and what needs doing, and we will give you a clear quote.
Do you cover Thorley Street for glazing silicone?
Yes. We work across London and the South East, and Thorley Street is part of that. You can call 0345 464 0079 or email us and tell us what needs doing, and we will give you a clear price.
Is there any odour?
That depends on the sealant. Some smell for a while, some hardly at all.
Can I do it myself?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
How long should I leave it?
It depends on the product and the temperature. We tell you how long to leave it before we go.
How long does the job take?
That depends on how much there is to do, but as a guide it takes anything from an hour or two to most of a day, depending on the size of the job. We’ll tell you when we quote.
Is it possible to redo the silicone on a shower screen?
Yes, it’s a common job. We use anti-fungal silicone suited to bathrooms.
Can a conservatory leak be sealed?
In many cases, as long as sealant is the cause. We trace the leak first before any sealing.
Aftercare tips
After the cure time, these simple habits help:
- Act on drips or damp patches early
- Run a squeegee over the glass when you are done
- Use a gentle glass cleaner and a soft cloth
- Look over the glazing joints once a year
Keep the new joints dry for as long as we advise so the silicone can set properly. After that, clean glass with a mild cleaner.
Don’t leave lifting or mouldy silicone on glazing. Once it starts to peel, water gets behind it and the leak gets worse.
DIY versus a professional finish
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
What the job involves on each surface
Shower screens
Most shower screen leaks come from the wall or tray joint. We reseal both with anti-fungal silicone.
Glass-to-frame joints
The sealant must stick to glass and frame alike. We use a glazing silicone suited to each.
Frames and glazing around Thorley Street
Historic houses like Much Hadham Palace (about 3.6 miles west) are a reminder that the area around Thorley Street 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. Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you look after a building such as Thorley Hill Primary School, the mastic around its windows and doors needs looking after like any other building’s. For an older house near a landmark such as Parish Church of St James the Great, frames set in older brick or stone need a sealant that suits the wall as well as the frame.
