Glazing silicone for homes and businesses in Cowfold
Cracked, stained or lifting silicone on glass spoils the look and lets water in. It comes off cleanly, without marking the glass before the new bead goes in. We work on glass-to-frame joints, glass balustrade bases and conservatory frames, and people most often call us about sealant that was laid over old silicone and failed and shower screens leaking along the wall or tray.
Somewhere as small as Cowfold, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.
Our work is backed for twelve months, in Cowfold and everywhere else we cover.

Surface by surface
Glass-to-glass joints
Frameless glass corners and panels are joined with silicone. We reseal with a suitable glazing silicone.
Rooflights
Rooflight glazing joints are cut out and renewed. Leaks from the roof itself need a roofer.
Can I do it myself?
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
If you’ve already had a go yourself, that is fine. We cut it out and start again, so tell us about it when you ask for a quote.
How we quote for glazing silicone
Some jobs are bigger than they look, and some smaller. What affects the quote:
- The number and length of the joints
- The old material and how stubborn it is
- Any mould that needs treating
- Working hours on commercial sites
What it costs depends on how much there is to do, how hard the old material is to remove and access to the work. You will have a clear quote before any work starts, so you know where you stand.
Asking for a quote
What to tell us when you ask for a quote:
- Any access issues, like height or stairs
- If it’s domestic, commercial or a hotel
- The rough size of the job
- Any previous sealing or DIY work
For a quote, call 0345 464 0079 or send us an email with the location and a short description of the problem. You will have a clear quote before work begins.
Why deal with it now?
A quick bead over the old sealant might stop a drip for a while, but silicone does not stick to silicone, and the leak normally returns. Cutting out and resealing properly lasts. Older cottages and farmhouses around Cowfold can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs, plus any working-time requirements on site. Call for a quick quote and we’ll go through it with you.
Why us?
- An ARBOMaster approved applicator
- Experience in homes, commercial sites and hotels
- Anti-fungal silicone where joints get wet
- Fully insured

Cowfold homes and the weather
The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you look after a building such as St Peter's CofE (Aided) Primary School, larger buildings have plenty of frames, and the mastic around each one ages.

How the visit works
We bring everything the job needs with us, so you do not need to buy or prepare anything. Once we’ve agreed what’s being done, we protect the area and start. Most jobs take a few hours for most jobs. Somewhere like Cowfold needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- First, we check where the water gets in.
- We remove the old sealant carefully.
- 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
- Plan for the work area to be out of bounds to pets and children
- Mention any sign-in or site rules at work premises
- Try not to wet indoor joints just before the visit

Common questions in Cowfold
Will you come out to Cowfold?
Yes, we do. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Is there a guarantee on glazing silicone in Cowfold?
Every job comes with our one-year guarantee, wherever it is. We’re also fully insured and ARBOMaster approved.
Is balustrade sealant something you do?
Yes. The old sealant is removed and the joint resealed with a suitable product.
Are you ARBOMaster approved?
Yes. We’re an ARBOMaster approved applicator.
How do I get a quote for glazing silicone in Cowfold?
It depends on the job, so we quote each one individually. For a quick quote, ring 0345 464 0079 or send us an email with a short description of the job.
Do the sealants smell?
Some sealants have a smell while they cure. Ventilation helps.
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.
Are you insured?
Yes. Mr Mastic is fully insured, with over 20 years’ experience in sealant work.
Keeping the joints in good condition
So the new joints stay in good condition:
- Act on drips or damp patches early
- Keep air moving in the conservatory
- Use a gentle glass cleaner and a soft cloth
- Don’t use a blade near the sealant
Squeegee a shower screen after each shower and let the room air. That slows mould growth on the bead.
A small conservatory leak soon spreads. Water runs along frames and down walls, so get it looked at when you first see it.
Do you need glazing silicone in Cowfold?
Using a sealant not made for glass causes many failures. Not every silicone sticks properly to glass, and acetoxy types can attack some frame materials.
The most common problems we see are:
- Cracked silicone between glass panels
- Leaking glazing joints on a rooflight
- Glazing silicone that has cracked or come away
- A quick top-up bead that didn’t last
If you live in an older home near Church of St Peter, the joint between an old wall and a newer frame is generally the first place rain gets in.
