Glazing silicone in Perry Vale
Glazing silicone that has yellowed, blackened or come away spoils the look and lets water in. We remove it without scratching the glass or frame before the new bead goes in. We work on glass-to-glass joints, shower screens and rooflights, and common reasons people get in touch are a quick top-up bead that didn’t last and water running down inside the glass.
London homes have every kind of window, from timber sashes in period terraces to aluminium and uPVC in newer blocks. The mastic around them dries out and cracks with age, which is when draughts and damp patches appear in homes in Perry Vale.
Our work is backed for twelve months.

Surface by surface
Glass balustrade bases
Glass balustrades sit in a channel that’s often finished with sealant. When it fails, water can sit in the channel.
Glass-to-glass joints
Where two panes meet, the silicone joint takes all the movement. The bead needs to be tidy and fully bonded.
The process
On the day, there’s very little for you to do. Show us the job and we’ll take it from there. The work itself takes a few hours for most jobs. In Perry Vale, flats, stairs and shared entrances are part of the routine. If the building has a concierge, managing agent or access rules, tell us when you book.
- 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.
- We lay the new bead and tool it smooth.
- We check the finished joints and test with water where it’s safe.
Getting ready for the visit
- Try not to wet indoor joints just before the visit
- Let us know if you’ve seen damp or leaks
- Clear the area around the work

Advice
What we are called out for in Perry Vale
Dirt and grease stop silicone sticking. If the glass and frame weren’t cleaned properly, the bead can peel away early.
If you can see any of these, it’s time to have the joints looked at:
- Leaking glazing joints on a rooflight
- Shower screens leaking along the wall or tray
- Mouldy sealant around glass panels
- Glazing silicone that has cracked or come away
Perry Vale is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.
Questions to ask before you book
- What insurance they hold
- How long the guarantee is
- What preparation is included
- When the joint can take water or movement
Leave it or put it right?
Replacing a conservatory roof is major work. If the leak is a failed sealant joint, resealing is far simpler. If the roof is the problem, we’ll say so. In London conversions, one flat’s bathroom is often above another flat’s ceiling, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Dealing with it early is far simpler for homes in Perry Vale.
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.

Frames and glazing around Perry Vale
London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Kingswood House (about 1.7 miles west) are a reminder that the area around Perry Vale has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
If you let a flat or house near Forest Hill station, a shower screen or conservatory joint that leaks is easier to reseal while the property is empty. Homes close to Christ 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.

Common questions in Perry Vale
Is parking an issue for glazing silicone in Perry Vale?
Parking in Perry Vale, as in most of London, takes a little planning: a visitor permit or a bay close to the door helps a lot, so mention what’s available when you book.
Do you work for landlords with property near Forest Hill station?
Yes, rental work is part of what we do. You can ring 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before we start.
Is a special sealant needed for glass?
A glazing-grade silicone is best. Ours is a neutral-cure glazing silicone and anti-fungal silicone in wet areas.
How long does the job take?
A typical job takes a few hours, depending on how many joints need doing, including preparation and clearing up. We’ll confirm how long when we quote.
Do you have insurance?
Yes. We’re fully insured, and we can confirm the details when we quote.
Is balustrade sealant something you do?
Yes, we reseal the joint at the base channel. Fitting glass is a separate trade.
