How we handle glazing silicone in St Leonards
Frameless shower screens rely on sealant to keep water in. The joint down the wall and the one along the tray are common leak points, and we reseal both. We’re often asked to deal with drips on the inside of a conservatory window and leaks where conservatory glass meets the frame, on rooflights, shower screens and glass-to-frame joints.
Plenty of homes in a town like St Leonards have had conservatories, patio doors or new windows added over the years. Each one adds more joints to look after, and those joints age at different rates. Leaks usually start at a sill, a frame head or a glazing joint.
Big or small, it’s backed by our one-year guarantee in St Leonards and across East Sussex.

St Leonards homes and the weather
St Leonards 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. 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.
In the older streets around St John the Evangelist's Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. If you look after a building such as St Leonard's Church of England Primary Academy, the mastic around its windows and doors needs looking after like any other building’s. Rented homes near St Leonards Warrior Square station change hands often, and a shower screen or conservatory joint that leaks is easier to reseal while the property is empty.

What happens on the day
Once we’re on site, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. Most jobs then take a few hours, depending on how many joints need doing. Parking in a town like St Leonards is normally straightforward, but tell us if there’s a driveway or any restrictions, and let us know if the work is upstairs, in a flat or up high outside.
- We start by finding the leak and making sure sealant is the cause.
- Old silicone is cut away from the glass and frame without scratching either.
- We clean the joint with a solvent that suits the glass and frame.
- We apply a neutral-cure glazing silicone and tool it smooth.
- The finished joints are checked and, where it’s safe, tested with water.
Before we arrive
- For indoor joints, keep the area dry beforehand if you can
- Plan for the work area to be out of bounds to pets and children
- Mention if the joints have been sealed before

Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all make a difference, and we’ll explain the quote if you ask.

What the job involves on each surface
Glass-to-glass joints
These joints are on show, so we take care to leave a neat bead.
Shower screens
Mouldy or lifting sealant on a screen leaks. A full reseal sorts it.
What happens if it’s left?
Resealing cannot fix a failed unit or a cracked panel. We say so plainly and point you to a glazier or roofer. Black mould and gaps in sealant don’t fix themselves, and in a busy home in St Leonards they get worse with every use. Now is the easy time to put it right.
Doing several joints on one visit generally makes better use of the time than several visits, so tell us about everything that needs sealing. We’ll send you a clear quote for the lot.
Why book with us
- Sealant colour chosen to suit
- One-year guarantee on every job

Questions from St Leonards
Is St Leonards in your area for glazing silicone?
Yes. We work across London and the South East, and St Leonards is part of that. You can call 0345 464 0079 or send us an email and let us know what needs doing, and we will send you a clear quote.
Does living near the coast affect glazing silicone in St Leonards?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. The right product, a clean joint and the right depth all help it cope.
Do you work for hotels and businesses?
Yes. Commercial and hotel work is a large part of what we do, as well as homes. Working times can be discussed when we quote.
Do you work for letting agents?
Yes. We work for householders, landlords, letting agents, businesses and hotels across East Sussex.
Do you hold any approvals?
Yes. We’re approved under the ARBOMaster scheme, which is run for the Arbo sealant brand.
I’m a tenant. Can you help?
Of course. Ask your landlord first, and we can send them the quote if that helps.
Do I have to be there?
It depends on the job. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.
Why not top up the existing silicone?
New silicone will not bond to old silicone and water gets between the layers. We cut out the old sealant first.
DIY sealant or a professional job?
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 need the right product, the right access and the right method.
