Why Do Windows Get Misty?
If you’ve noticed condensation building up between the panes of your double glazing, you’re not alone. It’s a common issue for many homeowners in the UK. Misty windows aren’t just unsightly – they’re also a sign that something’s gone wrong with your sealed units, and they may be costing you money through lost heat and reduced energy efficiency.
What Causes Windows to Mist Up?
Misted windows happen because the airtight seal between the panes of your double or triple glazing has failed. When this seal breaks, moisture gets in and condensation forms between the glass panes. Here are the main reasons why this happens:
- Age and wear: Over time, window seals naturally deteriorate.
- Poor installation: If your windows weren’t fitted properly, they may be more likely to fail.
- Temperature changes: Repeated heating and cooling can cause the seals to expand and contract, eventually leading to failure.
- Manufacturing defects: Sometimes the problem starts with the way the unit was made.
Is It a Big Problem?
While misted windows aren’t usually urgent, they do reduce your home’s energy efficiency. That means you’ll pay more on your heating bills. They also block natural light and make your windows look tired, even if the frames and glass aren’t damaged otherwise.
Can Misted Windows Be Repaired?
Yes – in most cases, you don’t need to replace the entire window. At Get My Windows Fixed, we can replace just the failed glass unit, keeping your existing frames intact. This is a quicker, more cost-effective option than replacing the whole window.
Repair vs. Replacement
Here’s how the two options compare:
- Glass unit replacement: Ideal if the frames are still in good condition. It’s quicker, less messy, and often saves you money.
- Full window replacement: Needed only if the frame is damaged, rotten, or very outdated.
We’ll always give honest advice about which option is best for your home.
How Much Does It Cost?
The cost to replace a misted double-glazed unit varies, typically starting from around £60–£120 per window, depending on the size and type of glass. When compared to replacing the full window, this can be a significant saving.
How to Prevent It Happening Again
While you can’t always prevent seal failure, you can take steps to reduce the risk:
- Choose quality replacement units with good seals
- Ensure proper installation by trained professionals
- Look for early signs of condensation and get them repaired quickly
