How we handle glazing silicone in Sidlesham
Frameless shower screens rely on sealant to keep water in. Leaks normally come from the wall joint or the tray joint and both get fresh anti-fungal silicone. If you have failed sealant around rooflight glass and glazing silicone that has cracked or come away, we can help, whatever the surface.
Outdoor sealant needs dry, clean surfaces, so work on frames around Sidlesham is planned for dry weather. Let us know about access to all the frames, upstairs ones included.
Big or small, it’s backed by our one-year guarantee.

Looking after it afterwards
No joint lasts for ever, but care makes a real difference. A few tips:
- Check the gutters above the glazing for debris
- Open vents or windows to let moisture out
- Stick to mild cleaners on glass
- Do not leave a drip for the next storm
Look over the glazing joints every year or so. Spotting a crack early means a simpler fix.
Conservatory leaks rarely stay small. Water travels along the frame and into the wall, so get it looked at when you first see it.
Frames and glazing around Sidlesham
Sidlesham is within about 1 mile of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That’s hard on glazing joints and frame seals, especially on the side facing the sea. Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you let a flat or house near Chichester station, glazing joints are worth checking at the end of a tenancy, before a small leak grows. For site and facilities teams at buildings such as Sidlesham Primary School, larger buildings have plenty of frames, and the mastic around each one ages.

Questions from Sidlesham
Does living near the coast affect glazing silicone in Sidlesham?
Near the sea, outside joints face more wind, rain and salt than they would inland, so preparation and the right sealant matter all the more. It’s worth checking the walls that face the sea first.
Do you cover smaller places like Sidlesham?
Yes. Sidlesham is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Is it possible to redo the silicone on a shower screen?
Yes, we do these often. We use anti-fungal silicone made for wet areas.
Can you just put new silicone over the old?
Topping up is a common cause of leaks. A proper job means cutting out, cleaning and resealing.
Is balustrade sealant something you do?
We can, if the base joint is sealed. Photos help us see what’s there.
Do you take out the old sealant first?
Yes. We cut out all the old sealant and clean the joint before applying anything new.
Can I add another job to the visit?
Yes. Tell us about everything you’d like done and you will get one quote.
Are you fully insured?
Yes. Mr Mastic is fully insured, and we’ve been doing sealant work for more than 20 years.
How the job changes by surface
Rooflights
Rooflights get the full force of the weather. The sealant around the glass and frame wears faster than most.
Conservatory frames
Frame joints face sun and rain all year. A fresh bead seals them again.

Should I try it myself first?
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.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
How it works
On the day, there’s very little for you to do. Show us the job and we’ll take it from there. The job generally takes a few hours, depending on how many joints need doing. Somewhere as small as Sidlesham, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- First, we check where the water gets in.
- The failed silicone is cut out without marking the glass or frame.
- We clean the glass and frame so the new silicone bonds.
- We lay the new bead and tool it smooth.
- We check the finished joints and test with water where it’s safe.
Getting ready for the visit
- Mention any parking rules near the property
- Keep children and pets away from the work area
- For business premises, tell us about site rules or sign-in

Related advice
What happens if it’s left?
Topping up old silicone can look like a fix, but silicone does not stick to silicone, and the leak usually returns. A proper reseal is the lasting answer. Around Sidlesham, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
What you pay reflects the work, not guesswork. That’s why we ask about the job first and send you a clear quote before we start.

What we are called out for in Sidlesham
Silicone will not bond to a dirty surface. Where the joint wasn’t cleaned and degreased the sealant may lift within a few years.
Signs it’s time to call us include:
- Shower screens leaking along the wall or tray
- Glass-to-glass joints that have split
- Black or yellowed silicone on glass joints
- Drips on the inside of a conservatory window
Homes close to St Mary Our Lady Sidlesham include some older properties, and the joint between an old wall and a newer frame is normally the first place rain gets in.
