Glazing silicone in Old Coulsdon
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. We work on conservatory frames, glass balustrade bases and shower screens, and common reasons people get in touch are leaks where conservatory glass meets the frame and failed sealant around rooflight glass.
London homes have every kind of window, from timber sashes in period terraces to aluminium and uPVC in newer blocks. Over the years, the sealant around them shrinks, cracks and pulls away, letting in draughts and water.
Your job is guaranteed for a year, as with all our work.

When to call us in Old Coulsdon
Silicone won’t bond to a dirty surface. If the glass and frame weren’t cleaned properly, the bead can peel away early.
The problems people normally mention when they call are:
- Cracked silicone between glass panels
- Leaks from the base of a shower screen
- Failed sealant around rooflight glass
- A quick top-up bead that didn’t last

I let a flat near Coulsdon South station. Can you help?

Do you offer different sealant colours?
We help you choose a colour that suits, from white and clear to greys and other shades. The product needed can limit the range.

What happens on the day
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 for most jobs from start to finish. In Old Coulsdon, as in most of London, parking needs a little planning. A visitor permit or a nearby bay makes the visit run more smoothly.
- We trace the leak and confirm it’s a sealant joint.
- The failed silicone is cut out without marking the glass or frame.
- We clean the glass and frame so the new silicone bonds.
- A neutral-cure glazing silicone is applied and tooled.
- We check the finished joints and test with water where it’s safe.
Getting ready for the visit
- Keep children and pets away from the work area
- Move anything stored near the joints
- Mention any parking rules near the property

What the job involves on each surface
Glass balustrade bases
The base of a glass balustrade is generally sealed. When it fails, water can sit in the channel.
Glass-to-glass joints
These joints are on show, so a straight, even finish matters.
What affects the quote in Old Coulsdon
The quote reflects the job in front of us. We look at:
- How easy the joints are to reach
- Whether there’s mould to deal with
- The product the joint needs
- Working hours on commercial sites
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, plus any working-time requirements on site. Call for a quick quote and we will explain what it covers.
What we need to know
A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- Any access issues, like height or stairs
- A few pictures by email, if you can
- Roughly how big the job is
- What’s wrong with the joints now
Every job is quoted individually, so the first step is telling us about yours. Just call 0345 464 0079 or drop us an email with the details.
Can I do it myself?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
Old Coulsdon homes and the weather
In London conversions and blocks, the lease decides who is responsible for the frames, so check that before you book. Historic houses like Addington Palace (about 5 miles north-east) are a reminder that the area around Old Coulsdon has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
Homes close to Church of St John the Evangelist include some older properties, and the joint between an old wall and a newer frame is generally the first place rain gets in. Old Coulsdon is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.

Why deal with it now?
If the problem is a misted unit or a broken panel, sealant will not help. We will tell you that rather than seal it anyway, so you can call the right trade. In London conversions, one flat’s bathroom is often above another flat’s ceiling, and a slow leak from a failed seal can end up in the flat below. Dealing with it early is far simpler.
