Repairing Faulty Double Glazing: A Guide to Fixing Blown Double Glazing
Double glazing is a great investment for any property. It keeps your home warm, reduces noise, and improves security. But what happens when the double glazing fails? One common issue is blown double glazing. It can cause condensation, fogging, and reduce the window’s efficiency. Today, we’ll walk through what blown double glazing is, how to spot it, and what you can do to fix it.
Understanding and Repairing Faulty Double Glazing
Double glazing consists of two glass panes separated by a spacer filled with air or gas. This setup provides insulation. When the seal between the panes breaks, moisture gets trapped inside. This is what we call blown double glazing.
You might notice fog or condensation between the panes. This means the insulating gas has escaped, and the window is no longer working as it should. The window will lose its thermal efficiency, and you may see an increase in your heating bills.
Repairing faulty double glazing is important to restore your window’s performance. Sometimes, the entire window unit needs replacing. Other times, a specialist can repair the seal or replace the glass pane.
Signs You Need to Repair Your Double Glazing
Knowing when to act is key. Here are some clear signs your double glazing needs attention:
Condensation or fogging between the glass panes.
Visible cracks or damage to the glass or seals.
Increased noise coming through the window.
Cold spots near the window, indicating heat loss.
Difficulty opening or closing the window due to swelling or warping.
If you spot any of these, it’s time to consider repair options. Ignoring the problem can lead to higher energy bills and discomfort.
How much does it cost to fix blown double glazing?
Costs vary depending on the extent of the damage and the type of window. Here’s a rough guide:
Glass pane replacement: £80 to £150 per pane.
Seal repair or replacement: £50 to £100.
Full window unit replacement: £200 to £500 or more.
Labour costs and window size also affect the price. It’s best to get a few quotes from local experts. Remember, investing in repairs can save money on heating and prevent further damage.
DIY or Professional Repair?
While some minor issues can be tackled at home, blown double glazing usually requires professional help. The seal and glass replacement need special tools and skills.
Attempting to fix it yourself might cause more damage or void any warranty. Professionals can assess the problem accurately and offer the best solution. They also ensure the repair meets safety and quality standards.
