Glazing silicone in Manor House, done properly
Conservatory leaks often start at a sealant joint, where glass meets frame or frame meets wall. We find the joint that’s letting water in and renew it and tell you plainly if the cause is something else. We’re often asked to deal with glazing silicone that has cracked or come away and leaking glazing joints on a rooflight, across glass-to-frame joints, shower screens and glass-to-glass joints.
London homes have every kind of window, from timber sashes in period terraces to aluminium and uPVC in newer blocks. Over the years, the sealant around them shrinks, cracks and pulls away, letting in draughts and water.
Each job carries a 12-month guarantee, large or small.

Keeping the joints in good condition
To keep the joints looking good and working properly:
- Keep air moving in the conservatory
- Check the silicone on glass every year or so
- Run a squeegee over the glass when you’re done
- Clean glass with a mild cleaner and a soft cloth
Use mild cleaners on and around the silicone. Strong solvents can soften or mark it.
Cracked glazing silicone means the joint has failed. Renewing it early keeps it simple compared with fixing water damage later.

Glass-to-glass joints
Silicone joins glass panels in many frameless designs. We reseal with a suitable glazing silicone.
Shower screens
Frameless screens rely on silicone at the base and wall. We renew it without marking the glass.
Common questions in Manor House
Can you help a landlord with a rental near Harringay Green Lanes station?
Yes. We work for landlords and letting agents as well as homeowners. You can ring 0345 464 0079 or send us an email with the details for a clear quote.
Is Manor House in your area for glazing silicone?
Yes. We work across London and the South East, and Manor House is part of that. You can call 0345 464 0079 or email us and tell us what needs doing.
Can I choose the sealant colour?
Generally, yes. Sealants come in white, clear, grey and other colours, and we agree the colour with you before we start.
Can I do it myself?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs.
Do you work for hotels and businesses?
Yes, regularly. Larger jobs can be planned room by room or area by area.
Do I need to be at home?
If the work is inside, we need someone to let us in. Once we’ve agreed the job, you don’t need to watch us work.
How long before the joint can be used?
Many sealants skin over quickly but take longer to cure fully. We will give you the cure time for the product we used before we leave.
How long does glazing silicone take?
Typically it takes anything from an hour or two to most of a day, depending on the size of the job. Larger jobs naturally take longer.
What happens on the day
Most of a good job is in the preparation, so that is where we spend the time. Joints are cleaned back and dried before anything new goes in. All told, the work takes anything from an hour or two to most of a day, depending on the size of the job. In Manor House, as in most of London, parking needs a little planning. It helps if you can point us to a visitor permit or a bay close to the door.
- We trace the leak and confirm it’s a sealant joint.
- The failed silicone is cut out without marking the glass or frame.

Related advice
DIY versus a professional finish
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.

Glazing silicone in Manor House: local notes
With historic houses such as Bruce Castle (about 2.1 miles north-east) nearby, there’s older building stock in the area around Manor House as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. 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 site and facilities teams at buildings such as Woodberry Down Community Primary School, larger buildings have plenty of frames, and the mastic around each one ages. If you live in an older home near Church of St Olave, frames set in older brick or stone need a sealant that suits the wall as well as the frame.
