- Glazing silicone that has cracked or come away
How we handle glazing silicone in Charlton
Our work covers conservatory joints, rooflights and glass panels, as well as frameless shower screens and glass balustrade bases. Each joint is cut out, cleaned and resealed. If you are dealing with split or lifting silicone on glass and a quick top-up bead that didn’t last, we can help.
Somewhere as small as Charlton, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.
Whatever the size of the job, you get the same one-year guarantee in Charlton and across Hampshire.

DIY sealant or a professional job?
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, and the work is guaranteed for a year.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Quotes for glazing silicone in Charlton
The price is agreed before any work begins. It’s based on:
- How much old sealant there is and how hard it is to remove
- Whether there’s mould to deal with
- The product the joint needs
- Access and height
Combining jobs into one visit is normally more efficient than separate visits, so tell us about everything that needs sealing. We’ll send you a clear quote for the lot.
Helping us quote
When you contact us, it’s useful to know:
- A few pictures by email, if you can
- The problem you’ve noticed
- If someone has resealed it before
- Where the job is, and your postcode
Getting a quote is simple: let us know the job and the location, and roughly how big it is. Photos by email help us understand the job.
Looking after it afterwards
No joint lasts for ever, but care makes a real difference. Our tips:
- Keep scrapers and blades away from the silicone
- Open vents or windows to let moisture out
- Get a new leak looked at quickly
- Use gentle products around the joints
Gentle products are best near the sealant. Strong solvents can soften or mark it.
Shower screen leaks can go unnoticed. Water can soak into the floor or reach the room below long before you see it.
Why act early in Charlton
Silicone around glazing needs the right product. A general-purpose tube may not bond well or may react with the frame, so we use neutral-cure glazing silicone. Older cottages and farmhouses around Charlton can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
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 we need extra access for height. Your quote takes all of that into account.

If you let a flat or house near Andover station, glazing joints are worth checking at the end of a tenancy, before a small leak grows. If you look after a building such as Harrow Way Community School, its window and door frames need their mastic kept sound, just like a home’s.

Do you need glazing silicone in Charlton?
Glass and frames expand and contract with the temperature, and they don’t move by the same amount. Over years, that movement tears the silicone.
Any of these means the joints need attention:
- Failed sealant around rooflight glass
- New silicone smeared over old sealant
- Water getting into a conservatory at the joints
- Drips on the inside of a conservatory window
In the older streets around St Thomas, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
