About our glazing silicone in Redhill
Many conservatory leaks come down to failed sealant at the glass-to-frame or frame-to-wall joints. We trace the leak to the joint and reseal it and tell you plainly if the cause is something else. If you are dealing with black or yellowed silicone on glass joints and failed joints on frameless glass, we can help.
Plenty of homes in a town like Redhill have had conservatories, patio doors or new windows added over the years. Every addition brings more joints, each wearing at its own pace. Sills, frame heads and glazing joints are where leaks normally start.
Each job carries a 12-month guarantee, whatever its size.

What sealant work can’t fix
To be straight with you, there are a few things sealant will not fix:
- A frame that needs repairing or replacing

What glazing silicone looks like in Redhill
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.
If you live in an older home near Saint Matthew's Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. If you let a flat or house near Redhill station, a shower screen or conservatory joint that leaks is easier to reseal while the property is empty. Managing a site like St Joseph's Catholic Primary School? Then larger buildings have plenty of frames, and the mastic around each one ages.

DIY sealant or a professional job?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
Some sealant jobs are within reach of a careful DIYer, 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.
What the job involves on each surface
Glass-to-frame joints
Glass-to-frame joints need a sealant that bonds to both. We choose a product that suits both.
Shower screens
A screen’s wall joint and tray joint are where leaks start. We reseal both with anti-fungal silicone.
What affects the cost of glazing silicone
Jobs vary more than people expect. What affects the quote:
- Whether old sealant or filler has to be cut out
- Access and height
- How many areas need sealing
- The type of sealant required
We do not show prices on the website, because the cost depends so much on the job itself. For a quick quote, please phone 0345 464 0079 or drop us an email.
What to tell us for a quote
Photos help, but a description is a good start. Please mention:
- The type of property
- The rough size of the job
- Whether it has been sealed before
- Any access issues, like height or stairs
For a quick quote, get us on the phone, or send an email if you’d rather. Tell us about the joints that need doing and we’ll talk you through the work and send you a clear quote.
What happens if it’s left?
Replacing windows or a shower screen is not needed for a failed joint. If the glass and frame are sound, new silicone is often all it takes. In a family home in Redhill, a failed seal around a bath or a frame lets water into places you can’t see, like the floor under a bath, the back of a panel or the inside of a wall. Whatever the joint, failed sealant only gets worse.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.

What else we do in Redhill
How it works
A visit follows a simple pattern: we check the joints, protect the area around them, carry out the job and clear up. Most jobs take a few hours for most jobs. Parking in a town like Redhill is usually straightforward, but tell us if there’s a driveway or any restrictions, and mention if the work is upstairs, in a flat or high on the outside.
- First, we check where the water gets in.
- The failed silicone is cut out without marking the glass or frame.
- The joint is cleaned and degreased.
- A neutral-cure glazing silicone is applied and tooled.
- Each joint is checked and, where possible, water-tested.
Preparing for the visit
- Tell us about any previous sealing or DIY attempts
- On commercial sites, let us know about site rules
- Try not to wet indoor joints just before the visit
