What we’re called out for in Mayfield
On shower screens, constant water and cleaning products wear silicone. Mould grows into the bead and the edges begin to peel.
Most people get in touch when they notice something like this:
- A quick top-up bead that didn’t last
- Leaking glazing joints on a rooflight
- Stained, discoloured glazing silicone
- Leaks from the base of a shower screen
In the older streets around Church of St. Dunstan, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
What to look for in a quote
- What the cure time is
- How the surfaces are prepared before sealing
- What insurance they hold
- Which sealant they’ll use, and why
About our glazing silicone in Mayfield
Not every silicone suits glass. We use a neutral-cure glazing silicone, which suits glass and most frame materials, finished with a neat, even bead. We work on glass-to-glass joints, rooflights and glass-to-frame joints, and common reasons people get in touch are glass-to-glass joints that have split and glazing silicone that has cracked or come away.
Mastic can only go onto a dry, clean joint, so window work in Mayfield is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
Our work is backed for twelve months.

Should I try it myself first?
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
The biggest DIY mistake is sealing over old sealant. 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.
Why it’s worth doing now in Mayfield
You do not need new glazing because the sealant has gone. Sound glass and frames usually just need resealing, and we will tell you if that’s not the case. Older cottages and farmhouses around Mayfield can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we will explain the quote if you ask.

How it works
On the day, we look over the joints with you first, so there are no surprises. We protect the surfaces around the joints before any work begins. Most jobs take a few hours for most jobs. Somewhere like Mayfield 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.
- We trace the leak and confirm it’s a sealant joint.
- The failed silicone is cut out without marking the glass or frame.
- The joint is cleaned and degreased.
- We lay the new bead and tool it smooth.
- We check the finished joints and test with water where it’s safe.

Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
What we need to know

- If it’s domestic, commercial or a hotel
- How many joints, rooms or windows are involved
- The problem you’ve noticed

Surface by surface
Rooflights
Rooflights get the full force of the weather. The sealant around the glass and frame wears faster than most.
Glass-to-glass joints
Silicone joins glass panels in many frameless designs. We renew it with a clear or matching glazing silicone.
Glazing silicone in Mayfield: local notes
Historic houses like Wadhurst Castle (about 4.3 miles north-east) are a reminder that the area around Mayfield 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, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
If you look after a building such as Mayfield Church of England Primary School, larger buildings have plenty of frames, and the mastic around each one ages. For landlords with property near Crowborough station, leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies.
