Glazing silicone in Palmers Green
Conservatory leaks often start at a sealant joint at the glass-to-frame or frame-to-wall joints. We trace the leak to the joint and reseal it, and if it’s something sealant can’t fix, we’ll tell you. Typical jobs include leaking glazing joints on a rooflight and sealant that was laid over old silicone and failed, on conservatory frames, glass balustrade bases and glass-to-glass joints.
London has a lot of flats and conversions, where windows are often on upper floors. Who looks after the outside of the frames can depend on the lease, so check that first, and access in Palmers Green is something to talk through when you book.
Big or small, you get the same 12-month guarantee.

Common problems we fix in Palmers Green
UV light ages silicone, especially on conservatory roofs. It goes brittle, cracks and stops sticking on the glass.
Signs it’s time to call us include:
- Water tracking down the inner face of the glass
- Split or lifting silicone on glass
- A quick top-up bead that didn’t last
- Leaks where conservatory glass meets the frame
If you live in an older home near Palmers Green United Reformed Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame.
Questions to ask before booking
- How the surfaces are prepared before sealing
- How the colour is chosen
- What happens if they find a problem under the old sealant
- How long the guarantee is
Why deal with it now?
Replacing windows or a shower screen isn’t needed for a failed joint. Sound glass and frames usually just need resealing. In a London flat, a failed joint rarely stays your problem alone: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.
The cost depends on the size of the job, how much old material has to come out and access to the work. We give a clear quote before any work starts.
What you get with us
- Quality sealants from Arbo and Everbuild

What we do, step by step
Most of a good job is in the preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it normally takes a few hours for most jobs. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Palmers Green. 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.
- We clean the glass and frame so the new silicone bonds.
- A neutral-cure glazing silicone is applied and tooled.
- Each joint is checked and, where possible, water-tested.
Before we arrive
- Where the joints are inside, avoid wetting them before we arrive
- Plan for the work area to be out of bounds to pets and children
- Clear items away from the joints we are working on

DIY sealant or a professional job?
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so just mention it when you contact us.
If you do try it yourself, take your time over the 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.
