Glazing silicone in Afton
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 conservatory frames, glass-to-glass joints and glass balustrade bases, and common reasons people get in touch are leaking glazing joints on a rooflight and drips on the inside of a conservatory window.
Around Afton, many homes face open ground, so their windows and doors take the full weather. That exposure dries out and cracks the mastic around frames and sills faster.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we’ll put it right.

Aftercare tips
How long the joints last depends on use and care. Here’s what we suggest:
- Look over the glazing joints once a year
- Clear the conservatory gutters regularly
- Wipe the screen down after showering
- Avoid strong solvents on or near the sealant
On shower screens, wipe or squeegee after use and keep the room ventilated. That slows mould growth on the bead.
Conservatory leaks rarely stay small. Water travels along the frame and into the wall so it’s best dealt with right away.
What we do, step by step
On the day, there’s very little for you to do. Point us to the joints and we will get on with it. The job generally takes a few hours, depending on how many joints need doing from start to finish. Somewhere like Afton 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.
- First, we trace the leak and check it’s coming through a sealant joint.
- Old silicone is cut away from the glass and frame without scratching either.
- The glass and frame are cleaned and degreased.
- Glazing silicone suited to the joint is applied and tooled.
- The finished joints are checked and, where it’s safe, tested with water.
How to prepare
- Let us know about parking restrictions
- For business premises, tell us about site rules or sign-in
- Where the joints are inside, avoid wetting them before we arrive

Related advice
Should I try it myself first?
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
How we quote for glazing silicone
The price is agreed before any work begins. It takes into account:
- How many rooms, windows or areas are involved
- Whether old sealant or filler has to be cut out
- How easy the joints are to reach
- The number and length of the joints
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. Your quote takes all of that into account.
Asking for a quote
When you contact us, these details help:
- The rough size of the job
- The type of property
- Photos by email, if that’s easy
- How we’d reach the joints
For glazing silicone in Afton, ring 0345 464 0079 or drop us an email. Tell us what the problem is and where, and we’ll agree the price before any work begins.
When it isn’t the sealant
Sealant is not the answer to every problem, and we’ll tell you before any work starts. It will not solve:
- Failed flashing around a conservatory
- Structural problems with a conservatory roof
- A sealed unit that has misted inside
If you’re not sure, just ring 0345 464 0079 or drop us an email and we will give you a straight answer.
Surfaces we seal
- Glass-to-frame joints
- Glass-to-glass joints
- Conservatory frames
- Glass balustrade bases
- Shower screens
- Rooflights
Why deal with it now?
Topping up old silicone can look like a fix, but new silicone won’t bond to old and water soon finds its way back. A proper reseal is the lasting answer. In a small place like Afton, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
There are no prices on our website, because each job is priced on what it involves. Call for a quick quote and we will talk you through it.

Frames and glazing around Afton
Afton is within about 1 mile of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That’s hard on glazing joints and frame seals, especially on the side facing the sea. The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Homes close to St. Agnes' Church include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame. Managing a site like All Saints Church of England Primary School? Then its window and door frames need their mastic kept sound, just like a home’s.
