Glazing & conservatory sealant in Berwick, Kent
Glazing silicone across Berwick and nearby, with every bit of old sealant taken out first.
- New silicone smeared over old sealant
- Water running down inside the glass
- Leaks from the base of a shower screen
Glazing silicone for homes and businesses in Berwick
Cracked, stained or lifting silicone on glass spoils the look and lets water in. It comes off cleanly, without marking the glass and reseal the joint. If you’re dealing with rooflight joints letting water in and water running down inside the glass, we can put it right, on glass balustrade bases, conservatory frames and glass-to-glass joints alike.
Homes in small places like Berwick 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.

Frames and glazing around Berwick
Berwick is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on glazing joints and frame seals, which can dry out and crack sooner where a building faces the weather. Historic houses like Westenhanger Castle (about 0.9 miles north) are a reminder that the area around Berwick has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
If you look after a building such as Lympne Church of England Primary School, the mastic around its windows and doors needs looking after like any other building’s. If you let a flat or house near Westenhanger station, leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies. If you live in an older home near Church of St Stephen, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

How the job changes by surface
Glass balustrade bases
Glass balustrades sit in a channel that’s often finished with sealant. When it fails, water can sit in the channel.
Rooflights
Rooflight glazing joints are cut out and renewed. Leaks from the roof itself need a roofer.
Should I try it myself first?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so tell us about it when you ask for a quote.
What sealant work cannot fix
We’ll always be straight with you, so here’s what sealant cannot fix:
- A roof that has moved or dropped
- Cracked or broken glass
- Failed flashing around a conservatory
If in doubt, call 0345 464 0079 or email us and we will say what we think.
Joints and surfaces we work on

How the visit works
Most of a good job is in the preparation, so that’s where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it normally takes anything from an hour or two to most of a day, depending on the size of the job. Somewhere as small as Berwick, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- 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.
- We check the finished joints and test with water where it’s safe.
How to prepare
- Tell us about access, such as stairs, a lift or high-level joints
- Tell us about any water getting in
- Move anything stored near the joints

Common questions in Berwick
Will you come out to Berwick?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
I let a flat near Westenhanger station. Can you help?
Yes, rental work is part of what we do. Just call 0345 464 0079 or send us an email and tell us about the property, and we will give you a clear price.
Do you offer different sealant colours?
We help you choose a colour that suits, from white and clear to greys and other shades. The product needed can limit the range.
What guarantee do I get?
Our one-year guarantee covers every job.
Do you reseal glass shower screens?
Yes, it’s a common job. We use anti-fungal silicone made for wet areas.
How long does glazing silicone take?
A typical job takes a few hours for most jobs. We’ll confirm how long when we quote.
Will the old sealant be removed?
Yes, always, and completely. New silicone does not stick to old silicone, so the joint is cleaned back first.
Does someone need to be in?
We need access to the joints, so we’ll agree that with you when we book. For inside work, that normally means someone being in.
For landlords and businesses
Mouldy or split sealant often shows up at the end of a tenancy. Several properties can be quoted together.
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
Aftercare tips
No joint lasts for ever, but care makes a real difference. A few tips:
- Act on drips or damp patches early
- Look over the glazing joints once a year
- Use a gentle glass cleaner and a soft cloth
- Keep conservatory gutters clear of leaves
Keep the new joints dry for as long as we advise so the silicone can set properly. From then on, a mild glass cleaner is all it needs.
Don’t leave lifting or mouldy silicone on glazing. Once it starts to peel, water gets behind it and the leak gets worse.
