Your questions about glazing silicone in Cocking
Is there a guarantee on glazing silicone in Cocking?
All our work, in Cocking and everywhere else, comes with a 12-month guarantee. We’re also fully insured and ARBOMaster approved.
Do you cover smaller places like Cocking?
Yes, Cocking is covered. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
What should I tell you?
A short description and the location, with pictures by email if possible. If we need more, we’ll ask.
Where is Mr Mastic based?
We’re based in Crawley, and we work across South East England, London and Scotland.
Do you offer different sealant colours?
Usually, yes. White, clear and grey are common, and other colours are available, and we agree the colour with you before we start.
Is balustrade sealant something you do?
We can. The old sealant is removed and the joint resealed with a suitable product.
Do you take out the old sealant first?
Yes, every time. New sealant will not bond properly to old, so any old material comes out before anything new goes in.
I’m a tenant. Can you help?
We’re happy to deal with the tenant, landlord or agent. Just make sure your landlord agrees.
How we handle glazing silicone in Cocking
Sealant on glazing doesn’t last for ever. Sun, rain and movement wear it down and cracked joints let water in. Renewing it keeps glazing joints doing their job. We work on glass balustrade bases, glass-to-frame joints and rooflights, and the jobs we see most are drips on the inside of a conservatory window and water getting into a conservatory at the joints.
Somewhere as small as Cocking, older homes often have timber frames set in stone or brickwork. Older buildings like these don’t always suit modern silicone, so the sealant has to be chosen to suit the building.
Each job carries a 12-month guarantee, large or small.

What glazing silicone looks like in Cocking
Historic houses like Cowdray House (about 2.6 miles north) are a reminder that the area around Cocking has older buildings as well as new. In older buildings, 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, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Around Cocking, as everywhere, glazing silicone is only as good as the preparation behind it.

How it works
There is not much for you to do on the day. Point us to the joints and we will get on with it. The job generally takes anything from an hour or two to most of a day, depending on the size of the job. Somewhere as small as Cocking, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- First we agree the joints to be done.
- Old sealant is removed from the glass and frame.
- The surfaces are cleaned with a suitable solvent.
- We apply and tool the new silicone.
- The joints are checked before we leave.
Getting ready for the visit
- On commercial sites, let us know about site rules
- Keep pets and children clear of the area while we work
- Where the joints are inside, avoid wetting them before we arrive

DIY versus a professional finish
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so just mention it when you contact us.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.

Keeping the joints in good condition
Joint life depends on how it’s used and looked after. We suggest:
- Ventilate the conservatory to cut condensation
- Avoid strong solvents on or near the sealant
- Wipe the screen down after showering
- Check the gutters above the glazing for debris
Check the joints once a year. Catching a split early keeps the repair small.
Shower screen leaks can go unnoticed. Water can soak into the floor or reach the room below long before you see it.
What affects the cost of glazing silicone
You’ll get a clear quote before we start. It’s based on:
- Any mould that needs treating
- How many rooms, windows or areas are involved
- The product the joint needs
- Working hours on commercial sites
The cost reflects the work involved, not guesswork. That’s why we ask a few questions first and give you a clear price before we start.
What to tell us for a quote
To make quoting easier, please include:
- Any access issues, like height or stairs
- The address or postcode of the job
- How many joints, rooms or windows are involved
- If it’s domestic, commercial or a hotel
Quotes start with a quick conversation. Describe the problem, the location and the size of the job. Whenever you’re ready, ring 0345 464 0079 or email us.
Leave it or put it right?
Dealing with a leaking shower screen early protects the floor and ceiling. Water from a failed joint can soak into the floor before you notice. Around Cocking, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.
Why us?
- Neat joints and a tidy finish
- Approved under the ARBOMaster scheme
- Any old sealant cut out fully, not covered over
- Sanitary silicone with an anti-fungal additive in wet areas

Do you need glazing silicone in Cocking?
Some conservatory leaks are not sealant at all: broken panels, roof problems and blocked gutters can all let water in. That’s why we trace the leak first.
The most common problems we see are:
- Silicone pulling away from the glass
- Failed sealant around rooflight glass
- Failed joints on frameless glass
- Water getting into a conservatory at the joints
If you live in an older home near St Catherine of Siena Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame.
What your quote should include
- How long to leave it before use
- Whether the sealant suits the joint
- Which colour the sealant will be
- How hidden problems are handled
What the job involves on each surface
Glass-to-frame joints
Silicone at the glass edge seals it into the frame. A failed bead lets water in.
Glass balustrade bases
Glass balustrades sit in a channel that is often finished with sealant. When it fails, water can sit in the channel.
