What affects the cost of glazing silicone
The price is agreed before any work begins. It takes into account:
- The number of rooms or windows
- Whether there’s mould to deal with
- Whether the work is at height
- The product the joint needs
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.
What to tell us for a quote
Before you ask for a quote, have a think about:
- How many joints, rooms or windows are involved
- Pictures of the joints, sent by email
- The address or postcode of the job
- How we’d reach the joints

Glazing silicone for homes and businesses in Childs Hill
Sealant on glazing does not last for ever. Sun, rain and movement wear it down and cracked joints let water in. Renewing it keeps glazing joints doing their job. If you have silicone pulling away from the glass and sealant that was laid over old silicone and failed, we can help, whatever the surface.
London’s Victorian and Edwardian terraces were built with timber sash windows, and many still have them or their replacements. Either way, the mastic between frame and brickwork is what stops draughts and rain getting in, in Childs Hill as anywhere.
All of our work is guaranteed for twelve months.

Should I try it myself first?
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.
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
What the job involves on each surface
Conservatory frames
Frame joints face sun and rain all year. Renewed sealant keeps water out.
Glass-to-frame joints
We cut the old silicone from the glass without scratching it and reseal with glazing silicone.
What glazing silicone looks like in Childs Hill
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. In London conversions and blocks, the lease decides who is responsible for the frames, so check that before you book.
Homes close to All Saints include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame. Childs Hill is in London, so parking needs planning: let us know about parking bays, permits or a driveway.

How to look after the new joints
Good habits help new joints last longer. A few tips:
- Clear the conservatory gutters regularly
- Clean glass with a mild cleaner and a soft cloth
- Look over the glazing joints once a year
- Squeegee the shower screen after each use
Squeegee a shower screen after each shower and keep the room ventilated. That slows mould growth on the bead.
Drips or damp near a glazing joint shouldn’t be ignored. It may be sealant, or something else, and we will tell you which.
What we cannot put right
A few problems are outside what sealant work can do:
- Failed flashing around a conservatory
- A sagging or failing conservatory roof
- A frame that needs repairing or replacing
Not sure which it is? You can phone 0345 464 0079 or send us an email and we will tell you honestly.
Surfaces we seal
- Glass balustrade bases
- Rooflights
- Conservatory frames
- Glass-to-frame joints

When to call us in Childs Hill
Sealant laid over old sealant does not last. Many failed joints we see have been topped up rather than cut out leaving a path for water.
If you can see any of these, it’s time to have the joints looked at:
- Leaks where conservatory glass meets the frame
- Sealant that was laid over old silicone and failed
- Rooflight joints letting water in
- Glass-to-glass joints that have split
Schools such as All Saints' CofE Primary School NW2 are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.

The process
When we arrive, we look over the joints with you first, so you know exactly what we’re doing. Surfaces next to the work are protected before work begins. The work normally takes a few hours, depending on how many joints need doing. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Childs Hill. A visitor permit or a nearby bay makes the visit run more smoothly.
- First, we trace the leak and check it’s coming through a sealant joint.
- Old silicone is cut away from the glass and frame without scratching either.
- Surfaces are cleaned with a solvent suited to glass and the frame.
- We apply a neutral-cure glazing silicone and tool it smooth.
- We look over every joint and, where we can, test it with water.
How to prepare
- On commercial sites, let us know about site rules
- Try not to wet indoor joints just before the visit
- Keep children and pets away from the work area
