About our glazing silicone in Castle Hill
Glass replacement isn’t something we do and a misted double-glazed unit needs a glazier. What we do is the silicone around the glass, which is where many leaks start. Typical jobs include split or lifting silicone on glass and water tracking down the inner face of the glass, on rooflights, glass-to-frame joints and shower screens.
Mastic can only go onto a dry, clean joint, so window work in Castle Hill is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
All our work comes with our one-year guarantee, wherever you are in Kent.

Different surfaces, different methods
Rooflights
Water around a rooflight isn’t always the sealant. We find the cause first.
Shower screens
Silicone holds the water in on frameless screens. We renew it without marking the glass.
Looking after it afterwards
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Wipe the screen down after showering
- Look over the glazing joints once a year
- Use gentle products around the joints
- Keep scrapers and blades away from the silicone
Look over the glazing joints every year or so. Spotting a crack early means a simpler fix.
Drips or damp near a glazing joint shouldn’t be ignored. It may be sealant, or something else and we’ll find out which.

Castle Hill questions
Is Castle Hill within the area you cover?
Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Do you cover Castle Hill for glazing silicone?
Yes. Our work covers London and the South East, and Castle Hill is part of that. Just call 0345 464 0079 or drop us an email with a few details of the job.
What sealant do you use on glazing?
A neutral-cure glazing silicone suited to glass and the frame. Shower screens get anti-fungal silicone.

Yes, we are fully insured.
Can you match the sealant colour?
Most of the time, yes. We will tell you which colours the right product comes in.
Is there any odour?
There can be a smell while the sealant cures, which fades as it sets. Ventilation helps.

We keep the work tidy. We protect what’s around the joints, and we clear up when we are done.
What guarantee do I get?
There’s a 12-month guarantee on every job, glazing sealant included.
Castle Hill homes and the weather
The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. With historic houses such as Scotney Castle (about 4.3 miles south) nearby, there’s older building stock in the area around Castle Hill 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.
Managing a site like Brenchley and Matfield Church of England Primary School? Then larger buildings have plenty of frames, and the mastic around each one ages. If you live in an older home near Parish Church of All Saints, frames set in older brick or stone need a sealant that suits the wall as well as the frame. For landlords with property near Paddock Wood station, glazing joints are worth checking at the end of a tenancy, before a small leak grows.

We bring what the job needs, so it can be finished in one trip where possible.

- We cut away the failed silicone.
- We clean and prepare the joint.
- We apply and tool the new silicone.
- The joints are checked before we leave.

Related advice
Can I do it myself?
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. Everything old must be removed first.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
When it is not the sealant
It helps to know what we can’t do too:
- A sealed unit that has misted inside
- Glass that needs replacing
- A roof that has moved or dropped
If in doubt, call 0345 464 0079 or send us an email and we will say what we think before booking.
