How we handle glazing silicone in Knowl Hill
Across Knowl Hill, we reseal glazing joints in homes, offices and hotels. Conservatories, rooflights, glass panels and shower screens are all part of the job. We work on rooflights, shower screens and glass balustrade bases, and people most often call us about shower screens leaking along the wall or tray and glazing silicone that has cracked or come away.
Homes in small places like Knowl Hill often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.
Big or small, it’s backed by our 12-month guarantee in Knowl Hill and across Wokingham.

What happens if it’s left?
Leaks get worse, not better. Water can damage frames, walls, flooring and furniture so early action saves a bigger repair. Where a wall is exposed, as many are in small places like Knowl Hill, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs. Call for a quick quote and we’ll explain what it covers.

Questions from Knowl Hill
Can you do glazing silicone in Knowl Hill?
Yes. Our work covers London and the South East, and Knowl Hill is part of that. You can ring 0345 464 0079 or send us an email and tell us what needs doing.
Can you help a landlord with a rental near Wargrave station?
Yes, rental work is part of what we do. You can call 0345 464 0079 or send us an email with the address and a few details, and we will give you a fixed price before we start.
Do you remove the old sealant?
Yes, every time. New silicone does not stick to old silicone, so the joint is cleaned back first.
Is it messy?
Not at all. The area is protected while we work and cleaned up afterwards.
Are you ARBOMaster approved?
Yes. We’re approved under the ARBOMaster scheme.
Do the sealants smell?
There can be a smell while the sealant cures, which fades as it sets. Ventilation helps.
Can you do several jobs on one visit?
Yes. Several rooms, windows or areas can go on one quote.
How long does glazing silicone take?
It depends on the size of the job, but as a guide it takes a few hours for most jobs. We will tell you when we quote.
Quotes for glazing silicone in Knowl Hill
Your quote is based on your job. We take into account:
- The number and length of the joints
- How many areas need sealing
- The product the joint needs
- When we can work, for business premises
Doing several joints on one visit generally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. You’ll get one clear quote for the whole job.
Helping us quote
Before you ask for a quote, have a think about:
- Any previous sealing or DIY work
- Roughly how big the job is
- Where the job is, and your postcode
- What’s wrong with the joints now
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is, and we’ll talk you through what we’d do. Whenever you are ready, ring 0345 464 0079 or send us an email.
What we’re called out for in Knowl Hill
Glass and frames expand and contract with the temperature, and they do not move by the same amount. In time, the sealant splits or pulls away.
It’s worth asking for a quote if you see:
- New silicone smeared over old sealant
- Stained, discoloured glazing silicone
- Drips on the inside of a conservatory window
- Leaks from the base of a shower screen
For an older house near a landmark such as Saint Peter, frames set in older brick or stone need a sealant that suits the wall as well as the frame.
Before booking anyone
- How the surfaces are prepared before sealing
- Who turns up on the day
- Is the old sealant removed completely?
- What product goes in the joint
Honest limits
In fairness, some problems need a different trade:
- A frame that needs repairing or replacing
- Structural problems with a conservatory roof
- Leaks from the roof covering or flashing (a roofer’s job)
Not sure which it is? You can call 0345 464 0079 or send us an email and we will tell you honestly before booking.

What glazing silicone looks like in Knowl Hill
With historic houses such as Harleyford Manor (about 3 miles north) nearby, there’s older building stock in the area around Knowl Hill as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For site and facilities teams at buildings such as Knowl Hill Church of England Primary Academy, its window and door frames need their mastic kept sound, just like a home’s. If you let a flat or house near Wargrave station, glazing joints are worth checking at the end of a tenancy, before a small leak grows.

Different surfaces, different methods
Shower screens
Mouldy or lifting sealant on a screen leaks. Cutting it out and resealing fixes it.
Glass balustrade bases
Balustrade bases are exposed outdoors. Renewing the sealant keeps water out of the channel.

Can I do it myself?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
