- Glazing silicone that has cracked or come away
What the job involves on each surface
Glass balustrade bases
Glass balustrades sit in a channel that’s often finished with sealant. Failed sealant there lets water collect.
Shower screens
Black or peeling silicone on a screen lets water out. Cutting it out and resealing fixes it.
Glazing silicone in Castle Town, done properly
Sealant on glazing doesn’t last for ever. Sun, rain and movement wear it down and cracked joints let water in. Resealing puts that right. Typical jobs include leaks where conservatory glass meets the frame and water running down inside the glass, on rooflights, shower screens and glass-to-frame joints.
Around Castle Town, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

DIY versus a professional finish
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Looking after it afterwards
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Act on drips or damp patches early
- Inspect the sealant on glazing annually
- Ventilate the conservatory to cut condensation
- Keep harsh solvents off the silicone
Squeegee a shower screen after each shower and keep the room ventilated. It helps stop mould getting into the silicone.
Shower screen leaks can go unnoticed. Water can soak into the floor or reach the room below long before you see it.
How the visit works
At the end, we look at the finished work together. The visit itself generally takes a few hours for most jobs, depending on how much there is to do. Somewhere as small as Castle Town, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- First, we trace the leak and check it’s coming through a sealant joint.
- 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.
- We look over every joint and, where we can, test it with water.
Getting ready for the visit
- Tell us about any water getting in
- Let us know about earlier repairs to the joints
- Keep pets and children clear of the area while we work

What affects the cost of glazing silicone
You will get a clear quote before work begins. It’s based on:
- Any working-time requirements on site
- The number and length of the joints
- Mould in or behind the old joints
- Access and height
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.
What we need to know
A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- Roughly how big the job is
- Any previous sealing or DIY work
- What’s wrong with the joints now
- Where the property is
A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is, and add pictures by email if you can.
What we’re called out for in Castle Town
Dirt and grease stop silicone sticking. Where the joint wasn’t cleaned and degreased, the bead can peel away early.
These are the problems we are asked about most:
- Mouldy sealant around glass panels
- Failed sealant around rooflight glass
- Glazing silicone that has cracked or come away
- Sealant that was laid over old silicone and failed
In the older streets around St Botolph's Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Frames and glazing around Castle Town
Historic houses like Portslade Manor (about 4.2 miles south-east) are a reminder that the area around Castle Town has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. 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.
For site and facilities teams at buildings such as Upper Beeding Primary School, the mastic around its windows and doors needs looking after like any other building’s. Letting a property close to Shoreham-By-Sea station? Then a shower screen or conservatory joint that leaks is easier to reseal while the property is empty.

Why act early in Castle Town
Replacing a conservatory roof is major work. If the leak is a failed sealant joint, resealing is far simpler. If it’s the roof itself, we will tell you. Older cottages and farmhouses around Castle Town can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
