- Shower screens leaking along the wall or tray

- Water tracking down the inner face of the glass
What the job involves on each surface
Rooflights
A rooflight faces rain and sun from above. The sealant around the glass and frame wears faster than most.
Glass-to-frame joints
The sealant must stick to glass and frame alike. We choose a product that suits both.
How we handle glazing silicone in Streatham
Across Streatham, we reseal glazing joints in homes, offices and hotels. Conservatories, rooflights, glass panels and shower screens are all part of the job. If you are dealing with a quick top-up bead that didn’t last and rooflight joints letting water in, we can help.
London has a lot of flats and conversions, where windows are often on upper floors. In a converted house or block, the lease normally says who is responsible for the windows, so it’s worth checking before booking.
A 12-month guarantee comes as standard, so you’re not left on your own once the job is done.

Streatham homes and the weather
With historic houses such as Kingswood House (about 2 miles east) nearby, there’s older building stock in the area around Streatham as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you let a flat or house near Streatham station, leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies. For site and facilities teams at buildings such as St Andrew's Catholic Primary School, its window and door frames need their mastic kept sound, just like a home’s.

How it works
Good joint work is mostly preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new goes in. In total, it usually takes anything from an hour or two to most of a day, depending on the size of the job. For a job in Streatham, parking and access are the things to plan: tell us about permits, visitor bays or off-street space, which floor we’re working on and whether there’s a lift.
- We look at the glazing and agree which joints need resealing.
- Old sealant is removed from the glass and frame.

What else we do in Streatham
When to call us in Streatham
Glass and frames expand and contract with the temperature at different rates. Over years, that movement tears the silicone.
Most people get in touch after spotting one of these:
- New silicone smeared over old sealant
- Cracked silicone between glass panels
- Conservatory leaks at frame and glazing joints
- Silicone pulling away from the glass
Homes close to St Leonard's 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.
What to look for in a quote
- Is the old sealant removed completely?
- What the cure time is
- Who does the work, and how experienced they are
- What preparation is included
Leave it or put it right?
A leaking joint won’t fix itself. Water can damage frames, walls, flooring and furniture, so it pays to deal with it early. Converted houses in London often have a bathroom above someone else’s living room, and a slow leak from a failed seal can end up in the flat below. Dealing with it early is far simpler for homes in Streatham.
Doing several joints on one visit is normally more efficient than separate visits. You’ll get one clear quote for the whole job.

Common questions in Streatham
Is Streatham in your area for glazing silicone?
Yes, Streatham is within the area we cover. Our work covers London and the South East. Just ring 0345 464 0079 or email us with a few details of the job, and we’ll send you a clear quote.
Is parking a problem for a job in Streatham?
It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. That way the visit can be planned around it.
Will it make a mess?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
Can a conservatory leak be sealed?
It depends on the cause. Sealant joints we can renew but roof and panel problems need another trade.
Which products do you use?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
Can you match the sealant colour?
Usually, yes. White, clear and grey are common, and other colours are available, and we will agree it with you first.
Do you work for hotels and businesses?
Yes. We have worked for hotels, offices and other businesses, and we are fully insured.
Can I add another job to the visit?
Yes. Tell us about everything you’d like done and we will quote it together.
DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
