How Misty Windows Are Costing You Money and What to Do About It

Misty Window Repair Essex & Suffolk

Have you noticed your windows looking foggy even when it’s all clear outside? That’s what we call misted windows. Aside from making it tough to enjoy the view, they’re quietly increasing your energy bills. Let’s dive into why they happen and how swapping them out can bring significant benefits to your home.

Understanding the Insulated Glazing Unit (IGU)

The “Insulated Glazing Unit” or IGU is a critical part of double or triple-glazed windows. It’s designed to keep the cold air out and the warm air in your home. But, if the seal around the IGU fails, moisture can get in between the window panes, causing that foggy look. 

This doesn’t just make it harder to see out of your window – it also means that any special insulating gas that was in there has probably escaped. So, your window isn’t working as well at keeping the heat in, and you end up losing more warmth from your home. That means your heating has to work harder, and your energy bills go up.

Financial Benefits of Replacing Misted Windows

While replacing misted windows does require an initial investment, the long-term financial benefits are substantial.

  1. Save on Energy Bills: The Energy Saving Trust estimates that replacing a single misted window with an energy-efficient alternative can save you up to £85 per year on your energy bills. For homes with multiple affected windows, these savings can quickly add up to hundreds of pounds annually.
  1. Increase Your Home’s Value: Not only can replacing foggy windows save you money on energy, but it can also make your home more valuable. Clear, well-maintained windows are a big plus for potential buyers and can help your home stand out in the market.

Choosing the Right Replacement Windows

When it comes to selecting replacement windows, there are several factors to consider:

Types of Energy-Efficient Windows

  • Double-glazed windows with special coatings that reflect heat
  • Triple-glazed windows for even better insulation
  • Windows filled with insulating gases like argon or krypton

What to Look for in a Good Replacement Window

  • The Energy Star label
  • High-quality frame materials (like uPVC, wood, or aluminium)
  • Strong, airtight seals
  • A good warranty from a trusted manufacturer

Lower Your Home Energy Bills

Old windows can be a major leak source for your home’s warmth, by as much as 25%. Upgrade to better, insulated PVC windows, and you could cut this loss dramatically, saving around £150 a year on heating. Investing in new windows also provides improved security and a host of finish options to upgrade your home’s look.
