Glazing silicone for homes and businesses in Charlton
Sealant on glazing doesn’t last for ever. Sun, rain and movement wear it down, and once it cracks, water follows. Resealing puts that right. We work on conservatory frames, glass-to-frame joints and glass balustrade bases, and the jobs we see most are new silicone smeared over old sealant and leaks where conservatory glass meets the frame.
Somewhere as small as Charlton, older homes often have timber frames set in stone or brickwork. Older buildings like these don’t always suit modern silicone, so the sealant has to be chosen to suit the building.
There’s a 12-month guarantee on every job, whatever its size.

Frames and glazing around Charlton
The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Rented homes near Hitchin station change hands often, and a shower screen or conservatory joint that leaks is easier to reseal while the property is empty. If you look after a building such as Highbury Infant School and Nursery, the mastic around its windows and doors needs looking after like any other building’s.

Common questions in Charlton
Do you cover Charlton for glazing silicone?
Yes, Charlton is within the area we cover. We work across London and the South East. Just phone 0345 464 0079 or drop us an email with a few details of the job, and we’ll give you a clear price.
Will you come out to Charlton?
Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Are you ARBOMaster approved?
Yes. We’re an ARBOMaster approved applicator, the approved applicator scheme for Arbo sealants.
How do I get a quote for glazing silicone in Charlton?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.
Do you remove the old sealant?
Always. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Can a conservatory leak be sealed?
That depends where the water is getting in. Sealant joints we can renew, but roof panels and structural problems need a conservatory specialist or roofer.

Only a few details: the address or postcode, what’s wrong and any access issues. After that, simply call 0345 464 0079 or send us an email.
I rent my home. Can I book you?
Yes, but check with your landlord or agent first. Many landlords are glad to have it sorted.
How it works
Every visit runs the same way: we check the joints, mask and protect the surrounding surfaces, carry out the job and tidy away. It usually takes anything from an hour or two to most of a day, depending on the size of the job. For a village or hamlet like Charlton, the journey is planned in advance: 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.
- We cut out the failed silicone, taking care of the glass and frame.
- Surfaces are cleaned with a solvent suited to glass and the frame.
- We apply a neutral-cure glazing silicone and tool it smooth.
- The finished joints are checked and, where it’s safe, tested with water.
Before we arrive
- For indoor joints, keep the area dry beforehand if you can
- Let us know if you’ve seen damp or leaks
- Mention any tricky access
Getting a quote
Getting a quote is simple: let us know the job and the location. A few pictures by email make the job easier to understand, and we’ll take it from there.

What affects the cost of glazing silicone
We quote each job individually. These are the things that affect it:
- Whether the work is at height
- When we can work, for business premises
- Whether there’s mould to deal with
- How much old sealant there is and how hard it is to remove
Doing several joints on one visit is normally more efficient than separate visits, so tell us about everything that needs sealing. You will get one clear quote for the whole job.
What we need to know
When you contact us, these details help:
- Roughly how big the job is
- Photos by email, if that is easy
- Any access issues, like height or stairs
- If it’s domestic, commercial or a hotel
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints, and add photos by email if you can.
How the job changes by surface
Glass balustrade bases
We reseal the joint where the glass meets the base channel. Glass fitting is a separate trade.
Glass-to-frame joints
Old sealant is removed carefully from the glass and reseal with glazing silicone.
What we’re called out for in Charlton
Silicone will not bond to a dirty surface. If the glass and frame weren’t cleaned properly the sealant may lift within a few years.
It’s worth asking for a quote if you see:
- Water running down inside the glass
- Silicone pulling away from the glass
- Conservatory leaks at frame and glazing joints
- Leaks from the base of a shower screen
In the older streets around St Mary's Church, the joint between an old wall and a newer frame is normally the first place rain gets in.

How to look after the new joints
After the cure time, these simple habits help:
- Inspect the sealant on glazing annually
- Avoid scraping close to the bead
- Clear the conservatory gutters regularly
- Act on drips or damp patches early
Gentle products are best near the sealant. Harsh solvents may damage the bead.
Cracked glazing silicone means the joint has failed. Renewing it early keeps it simple compared with fixing water damage later.
