Glazing silicone in Croxley Green, done properly
Glazing silicone is a maintenance item. Sun, rain and movement wear it down and cracked joints let water in. Renewing it keeps glazing joints doing their job. We work on glass-to-glass joints, shower screens and glass balustrade bases, and people most often call us about conservatory leaks at frame and glazing joints and water tracking down the inner face of the glass.
In a village or hamlet like Croxley Green, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.
All of our work is guaranteed for twelve months.

What happens on the day
There’s no need to move everything out before we come, just the space around the work. Everything nearby is protected, and the work takes a few hours, depending on how many joints need doing in most cases. For a village or hamlet like Croxley Green, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- First, we trace the leak and check it’s coming through a sealant joint.
- The old sealant is removed from the glass and frame without scratching them.
- The glass and frame are cleaned and degreased.
- We apply a neutral-cure glazing silicone and tool it smooth.
- We look over every joint and, where we can, test it with water.

Glass-to-frame joints
Silicone at the glass edge seals it into the frame. A failed bead lets water in.
Shower screens
Silicone holds the water in on frameless screens. We reseal without scratching the glass.
What glazing silicone looks like in Croxley Green
With historic houses such as Chenies Manor House (about 4.2 miles north-west) nearby, there’s older building stock in the area around Croxley Green 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, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Homes close to St Oswald's Parish Church include some older properties, and the joint between an old wall and a newer frame is usually the first place rain gets in. Schools such as Harvey Road Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.

What affects the quote in Croxley Green
For a quick quote, just ask. The main things that affect it are:

- How we’d reach the joints

Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Keep air moving in the conservatory
- Check the gutters above the glazing for debris
- Squeegee the shower screen after each use
- Stick to mild cleaners on glass
Follow the cure time we give you before the joints get wet so the silicone can set properly. After that, clean glass with a mild cleaner.
Shower screen leaks can go unnoticed. It can damage the floor or the ceiling below before you spot it.
DIY versus a professional finish
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.

Will you come out to Croxley Green?
Yes, we do. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Do you take out the old sealant first?
Yes. Sealing over the old bead is the commonest cause of early failure, so we never do it.

I rent my home. Can I book you?

It depends on the job. For work indoors, someone needs to let us in, and for outside work we will agree access with you when we book.
Do you need glazing silicone in Croxley Green?
Some conservatory leaks are not sealant at all: failed roof panels, slipped glazing bars and blocked gutters cause them too. We find the cause before we seal anything.
It’s worth asking for a quote if you see:
- Glass-to-glass joints that have split
- Shower screens leaking along the wall or tray
- Drips on the inside of a conservatory window
- Split or lifting silicone on glass
For landlords with property near Rickmansworth station, a shower screen or conservatory joint that leaks is easier to reseal while the property is empty.
