How we handle glazing silicone in Leamouth
Glass, frames and walls all move at different rates, and the silicone between them takes the strain. Once it splits or comes away, water finds a way through. We cut it out and reseal with a glazing silicone suited to the joint. If you’re dealing with stained, discoloured glazing silicone and conservatory leaks at frame and glazing joints, we can help.
Many London homes are flats, with windows high above the street. In a converted house or block, the lease usually says who is responsible for the windows, so it’s worth checking before booking.
There’s a 12-month guarantee on every job.

What sealant work cannot fix
We’d rather tell you now than do work that won’t last, so here’s what sealant can’t put right:
- Structural problems with a conservatory roof
- Cracked or broken glass
- Leaks from the roof covering or flashing (a roofer’s job)
If you’re not sure, just phone 0345 464 0079 or drop us an email and we’ll give you a straight answer before booking.
Surfaces we seal
- Glass-to-glass joints
- Glass-to-frame joints
- Glass balustrade bases
- Shower screens
- Conservatory frames
- Rooflights
Aftercare tips
No joint lasts for ever, but care makes a real difference. A few tips:
- Avoid strong solvents on or near the sealant
- Use a gentle glass cleaner and a soft cloth
- Wipe the screen down after showering
- Keep conservatory gutters clear of leaves
Use mild cleaners on and around the silicone. Harsh solvents may damage the bead.
Act on black or lifting silicone early. Peeling silicone lets water in behind and the problem grows.
Questions from Leamouth
Can you do glazing silicone in Leamouth?
Yes, Leamouth is within the area we cover. We work across London and the South East. You can call 0345 464 0079 or send us an email and let us know what needs doing, and we will send you a clear quote.
Can parking be tricky for a visit in Leamouth?
In much of London, parking needs planning: a visitor permit or a bay close to the door helps a lot, so mention what’s available when you book.
Where are you based?
We are based in Crawley, and we work across South East England, London and Scotland.
Should I try DIY first?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. If it does not work out, we can redo it.
Do you offer different sealant colours?
We will suggest a colour to suit the surroundings, from white and clear to greys and other shades. The choice depends on the product the joint needs.
Do you remove the old sealant?
Yes, always, and completely. New silicone doesn’t stick to old silicone, so any old material comes out before anything new goes in.
Do you work for landlords and businesses?
Yes, often. Several properties can be quoted together, and between tenancies is a good time for the work.
Do the sealants smell?
That depends on the sealant. Some smell for a while, some hardly at all, and any smell fades as they cure.
Common problems we fix in Leamouth
Sealant laid over old sealant does not last. Many failed joints we see have been topped up rather than cut out, and water gets between the layers.
The problems people usually mention when they call include:
- Black or yellowed silicone on glass joints
- Shower screens leaking along the wall or tray
- Failed joints on frameless glass
- Drips on the inside of a conservatory window
Schools such as St Luke's Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.

Leamouth homes and the weather
In London conversions and blocks, the lease decides who is responsible for the frames, so it’s worth checking before booking. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Homes close to Church of St Luke include some older properties, and the joint between an old wall and a newer frame is generally the first place rain gets in. Rented homes near Custom House station change hands often, and glazing joints are worth checking at the end of a tenancy, before a small leak grows.
