How to look after the new joints

How long the joints last depends on use and care. Here’s what we suggest:

  • Look over the glazing joints once a year
  • Act on drips or damp patches early
  • Keep air moving in the conservatory
  • Wipe the screen down after showering

Follow the cure time we give you before the joints get wet so the silicone can set properly. After that, clean glass with a mild cleaner.

A leaking shower screen may not show at first. Water can soak into the floor or reach the room below long before you see it.

Glazing silicone in Barnes

Not every silicone suits glass. We use a neutral-cure glazing silicone, which suits glass and most frame materials, and we tool it to a neat, even finish. We’re often asked to deal with black or yellowed silicone on glass joints and leaking glazing joints on a rooflight, on shower screens, conservatory frames and glass-to-frame joints.

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, letting in draughts and water.

All of our work is guaranteed for twelve months.

When to call us in Barnes

Dirt and grease stop silicone sticking. If the glass and frame weren’t cleaned properly the sealant may lift within a few years.

It’s worth asking for a quote if you see:

  • Black or yellowed silicone on glass joints
  • Drips on the inside of a conservatory window
  • A quick top-up bead that didn’t last
  • Cracked silicone between glass panels

If you let a flat or house near Barnes Bridge station, glazing joints are worth checking at the end of a tenancy, before a small leak grows.

10 questions to ask before booking

FAQs for Barnes

Can you help a landlord with a rental near Barnes Bridge station?

Yes. We work for landlords and agents as well as householders. You can call 0345 464 0079 or send us an email with the details for a clear quote.

Is parking an issue for glazing silicone in Barnes?

Parking in Barnes, 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.

Can you replace a misted double-glazed unit?

That’s not something we do. Misting between panes means the sealed unit has failed, and a glazier needs to replace it.

Can you match the sealant colour?

In most cases you can choose. We’ll explain which colours are available and agree one before work begins.

Will you leave a mess?

Tidy work is part of the job. Nearby surfaces are protected, and we clear up when we’re done.

Where are you based?

We work from Crawley. We cover Barnes and the rest of Greater London, along with the rest of our area.

Are you fully insured?

Yes. We’re fully insured.

What sealant do you use?

Quality sealants from brands including Arbo and Everbuild, picked for each joint. We explain the product when we quote.

What we do, step by step

You do not need to clear the whole room or building, only the area right around the joints. We protect the rest, and the work takes anything from an hour or two to most of a day, depending on the size of the job in most cases. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. Mention any building rules, key holders or managing agents when you book.

  1. We find where water is getting in and check whether it’s a sealant joint.
  2. The old sealant is removed from the glass and frame without scratching them.
  3. Surfaces are cleaned with a solvent suited to glass and the frame.
  4. We apply a neutral-cure glazing silicone and tool it smooth.
  5. We check the joints and, where safe, run water over them.

Before we arrive

  • For indoor joints, keep the area dry beforehand if you can
  • Mention if the joints have been sealed before
  • Tell us about any water getting in

How to get a quote

It all starts with a short chat. Describe the problem, the location and the size of the job, and we’ll explain how we’d tackle it. When it suits you, ring 0345 464 0079 or send us an email.

How the job changes 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

Silicone joins glass panels in many frameless designs. We reseal with a suitable glazing silicone.

Honest limits

A few problems are outside what sealant work can do:

  • Misting between the panes of a double-glazed unit (a failed unit for a glazier)
  • Structural problems with a conservatory roof
  • A frame that needs repairing or replacing

If in doubt, phone 0345 464 0079 or send us an email and we will say what we think.

What we seal

  • Glass balustrade bases

  • Where the property is
  • Any access issues, like height or stairs
  • Photos by email, if that is easy
  • Any previous sealing or DIY work

Glazing silicone in Barnes: local notes

With historic houses such as Chiswick House (about 0.9 miles north-west) nearby, there’s older building stock in the area around Barnes 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. London and the South East are among 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 live in an older home near Barnes Methodist Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. As a London address, Barnes can be tricky for parking: let us know about parking bays, permits or a driveway.

Why it’s worth doing now in Barnes

Topping up old silicone can look like a fix, but new silicone will not bond to old and water soon finds its way back. A proper reseal is the lasting answer. Damp from a failed joint spreads quietly in older London brickwork and timber, and once it shows in Barnes, the repair is bigger than a sealant job.

Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. We take all of that into account in your quote.
