Glazing silicone in Heyshott Green
Glass, frames and walls all move at different rates, and the silicone between them takes the strain. When it cracks or lets go, water gets in. We replace it with a glazing silicone that suits the glass and frame. We work on glass balustrade bases, shower screens and glass-to-glass joints, and people most often call us about silicone pulling away from the glass and cracked silicone between glass panels.
In a village or hamlet like Heyshott Green, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these do not always suit modern silicone, so the sealant has to be chosen to suit the building.
Whatever the size of the job, you get the same one-year guarantee in Heyshott Green and across West Sussex.

What we do, step by step
Before we leave, we go over the finished joints with you and explain the cure time. The work normally takes a few hours, depending on how many joints need doing, depending on how much there is to do. Somewhere like Heyshott Green needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- 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.
- Each joint is checked and, where possible, water-tested.
Preparing for the visit
- Clear items away from the joints we’re working on
- Let us know about stairs, lifts or work at height
- Tell us if parking is tricky

Advice
How the job changes by surface
Glass-to-frame joints
Silicone at the glass edge seals it into the frame. A failed bead lets water in.
Conservatory frames
The joints where the conservatory meets the house take a lot of movement. They’re resealed with a suitable sealant.
Keeping the joints in good condition
Simple care keeps the joints in good condition. Our advice:
- Keep scrapers and blades away from the silicone
- Stick to mild cleaners on glass
- Open vents or windows to let moisture out
- Keep conservatory gutters clear of leaves
Keep conservatory gutters clear, so water drains away from the joints. Overflowing gutters can cause leaks of their own.
Damp patches, drips and condensation along a joint are worth checking. The cause may be sealant or another part and we will find out which.
FAQs for Heyshott Green
Do you cover Heyshott Green for glazing silicone?
Yes. Our work covers London and the South East, and Heyshott Green is part of that. You can call 0345 464 0079 or send us an email and tell us what needs doing.
Is glazing silicone in Heyshott Green guaranteed?
All our work, in Heyshott Green and everywhere else, comes with a 12-month guarantee. We’re also fully insured and ARBOMaster approved.
Why not top up the existing silicone?
Silicone does not stick to silicone and water gets between the layers. We cut out the old sealant first.
Are you insured?
Yes. Mr Mastic is fully insured, with over 20 years’ experience in sealant work.
Can tenants book the work?
Of course. Check with your landlord; we can send the quote to them too.
Do you hold any approvals?
Yes. Mr Mastic is an ARBOMaster approved applicator and we’re fully insured too.
What should I tell you?
The location, the problem and the rough size of the job. Photos by email help too.
Do the sealants smell?
Sometimes, a little. It fades as the sealant cures, and ventilation helps.
What we cannot put right
In fairness, there are a few things sealant will not fix:
- A sagging or failing conservatory roof
- Leaks from the roof covering or flashing (a roofer’s job)
- Condensation trapped between two panes
If in doubt, phone 0345 464 0079 or email us and we will say what we think before you book.
Surfaces we seal
- Glass-to-frame joints
- Glass balustrade bases
- Conservatory frames
- Shower screens
- Rooflights
- Glass-to-glass joints
Do you need glazing silicone in Heyshott Green?
Some conservatory leaks aren’t sealant at all: broken panels, roof problems and blocked gutters can all let water in. We find the cause before we seal anything.
Most people get in touch after spotting one of these:
- Leaks from the base of a shower screen
- Stained, discoloured glazing silicone
- Leaking glazing joints on a rooflight
- Glazing silicone that has cracked or come away
If you look after a building such as Midhurst Rother College, the mastic around its windows and doors needs looking after like any other building’s.
What your quote should include
- What happens if the job turns out different
- Is VAT in the price?
- What insurance they hold
- When the joint can take water or movement
Heyshott Green homes and the weather
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. With historic houses such as Cowdray House (about 1.9 miles north) nearby, there’s older building stock in the area around Heyshott Green as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
For an older house near a landmark such as The Parish Church of St James, the joint between an old wall and a newer frame is usually the first place rain gets in.
