Removing a Pane of Glass from Double Glazing

Double glazing in our homes, including the Pane of Glass from Double Glazing, is a wonderful way to keep our homes insulated, secure, and safe from excessive noise. Our homes have had double glazing as standard for the last 50 years or so, with 93% of British houses having double glazing installed. However, they’re only effective as long as they are in good working order.

Once they start to break down, they begin to lose their effectiveness almost immediately and can even promote damaging condensation within the home, leading to the build-up of black mould. Black mould threatens both the structural integrity of your home and the health of the occupants, so it is important to ensure that your double glazing is in good working order.

Knowing when to get a replacement.

You’ll know that you need to replace a pane of glass in your unit if you spot any of the following issues:

  1. The glass has clouded over. You won’t be able to see clearly through the glass, nor will you be able to wipe away the cloudiness from the outside or the inside. This means the clouding is occurring between the two panes.
  2. You can see droplets appearing inside the glass. This will be the next step after the clouding of the glass. As the condensation increases, water droplets will start to form in place of fog, a clear sign that the glass needs replacing.
  3. There are chips or cracks in the glass. They can be quite hard to spot at first glance, but you must check for them regularly as they can worsen over time.
  4. A draught. If you can feel air coming through the window even when it is shut, you need to replace the glass in the window as the draught will reduce your home’s energy efficiency.

Choosing to do it yourself.

The replacement of the glass will be somewhere around £50-£150 depending on the size of the window. So if you would prefer to do it yourself, here is a rough step by step guide on how to do this:

  1. Remove the wedge gasket from the inside of the window. Start from the middle and work your way out from there, as this will give you the best leverage to pull it out without tearing it (which will make it difficult to pull out completely).
  2. Head to the outside of the window and remove the double glazing beads. Leave the top one till last, so it doesn’t fall on your head.
  3. Keep track of the glazing packs and locations before removing them from the top and sides.
  4. Remove the blown unit. Use a double cup suction lifter if you have one, as this provides the safest way to move the glass without risking breaking it.
  5. Check the glazing packs at the bottom of the window and replace the unit on top.
  6. Keep it secure whilst you return the glazing packs to their original location.
  7. Keep it secure whilst you return their beads to their original location, starting at the top.
  8. Replace the wedge gasket to lock it all into place.

Whilst the process is simple, it can be a bit fiddly, and handling glass is always dangerous. If you’re not feeling confident, we recommend hiring a professional to do it for you.
