How we handle glazing silicone in Chiswick

Across Chiswick, we reseal glazing joints in homes, offices and hotels. Conservatories, rooflights, glass panels and shower screens are all part of the job, with a sealant chosen for the joint. We work on glass balustrade bases, glass-to-frame joints and conservatory frames, and the jobs we see most are shower screens leaking along the wall or tray and split or lifting silicone on glass.

From mansion-block windows to modern glazing in new flats, London has every kind of frame. The mastic around them dries out and cracks with age, letting in draughts and water.

We stand behind the work with a one-year guarantee, so you’re not left on your own once the job is done.

Keeping the joints in good condition

Simple care keeps the joints in good condition. We recommend:

  • Use a gentle glass cleaner and a soft cloth
  • Use gentle products around the joints
  • Open vents or windows to let moisture out
  • Look over the glazing joints once a year

Gentle products are best near the sealant. Harsh solvents may damage the bead.

A small conservatory leak soon spreads. Water runs along frames and down walls, so get it looked at when you first see it.

Why it’s worth doing now in Chiswick

If the problem is a misted unit or a broken panel, sealant will not help. We say so plainly, so you can call the right trade. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and by the time it shows on a wall or ceiling in Chiswick, the repair is bigger than the sealant job would have been.

Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs, along with when we can work on site. Call for a quick quote and we’ll explain what it covers.

What you get with us

  • We’re fully insured
  • Old sealant always removed completely
  • Anti-fungal silicone where joints get wet
  • More than 20 years in sealant work

What glazing silicone looks like in Chiswick

Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. In a converted house or block, who looks after the windows depends on the lease, so it’s worth checking before booking.

Homes close to St. Nicholas Church include some older properties, and the joint between an old wall and a newer frame is usually the first place rain gets in. For landlords with property near Chiswick station, a shower screen or conservatory joint that leaks is easier to reseal while the property is empty.

DIY sealant or a professional job?

Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.

A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

Common problems we fix in Chiswick

Sealant laid over old sealant does not last. Plenty of leaks come from a quick top-up over the old bead, and water gets between the layers.

Most people get in touch after spotting one of these:

  • Conservatory leaks at frame and glazing joints
  • Silicone pulling away from the glass
  • Sealant that was laid over old silicone and failed
  • Water running down inside the glass

If you look after a building such as The William Hogarth Primary School, the mastic around its windows and doors needs looking after like any other building’s.

What your quote should include

  • What happens if the job turns out different
  • Are they insured?
  • Is the old sealant removed completely?
  • Whether the sealant suits the joint

How to choose a mastic man

What the job involves on each surface

Glass-to-frame joints

Silicone at the glass edge seals it into the frame. A failed bead lets water in.

Glass balustrade bases

The base of a glass balustrade is usually sealed. When it fails, water can sit in the channel.

Common questions in Chiswick

Is parking an issue for glazing silicone in Chiswick?

In much of London, parking needs planning: a visitor permit or a nearby bay makes the day run more smoothly.

Is Chiswick in your area for glazing silicone?

Yes. Our work covers London and the South East, and Chiswick is part of that. You can phone 0345 464 0079 or drop us an email and let us know what needs doing, and we’ll give you a clear price.

Is there any odour?

Some sealants have a smell while they cure, which fades as it sets. Opening a window helps.

Can you work on commercial sites?

Yes. We work in offices, washrooms, hotels and other commercial premises. We can talk about working times when we quote.

Can I choose the sealant colour?

We’ll suggest a colour to suit the surroundings, from white and clear to greys and other shades. The product needed can limit the range.

What should I tell you?

A short description and the location, plus pictures if you have them. If we need more, we will ask.

Do you guarantee glazing sealant work?

Every job comes with our one-year guarantee, and we’re fully insured.

When is the sealant fully cured?

That depends on the sealant used, so please follow the time we give you when we finish.

The process

There’s no need to move everything out before we come, just the space around the work. Everything nearby is protected, and the job takes a few hours for most jobs for a typical job. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Chiswick. A visitor permit or a nearby bay makes the visit run more smoothly.

  1. First, we check where the water gets in.
  2. The failed silicone is cut out without marking the glass or frame.
  3. We clean the glass and frame so the new silicone bonds.
  4. We lay the new bead and tool it smooth.
  5. We check the finished joints and test with water where it’s safe.

Getting ready for the visit

  • Mention any sign-in or site rules at work premises
  • Tell us about any water getting in
  • Plan for the work area to be out of bounds to pets and children
