Clear the Fog: Fixing Misted Windows Before Winter Ruins Your View

Is condensation ruining your view this winter?

There’s nothing quite like a frosty December morning — twinkling lights outside, a hot drink in hand, and the peaceful feeling of home. But if your windows are misted up on the inside, blocking your view and letting in the cold, it’s hard to feel cosy.

That’s exactly what happened to one of our customers in East Lothian. Their Velux window had become more fog than function. But the fix? Much easier than they thought.

Misted windows don’t always mean full replacements

This customer had condensation trapped between the panes of their double glazing. It was ruining their view and letting cold air creep in — right in the middle of winter. But instead of replacing the whole window, we simply installed a new sealed unit. The result? A clear view, a warmer room, and another happy homeowner ready to enjoy Christmas in comfort.

Why does condensation build up inside double glazing?

If you’re seeing mist between the panes of glass, the seal has failed. That means moisture has gotten into the space between, and no surface cleaning will fix it — because the problem is inside the glass.

This is common in Velux windows and older units that have faced years of weather. Over time, seals break down and allow air and moisture to sneak in.

Signs your double glazing needs attention:

• Fog or mist inside the window, between the glass

• Cloudy or streaky glass that won’t clean up

• The area near the window feels colder than the rest of the room

• Your heating bills are creeping up

• The window is older or has been through extreme weather

If you’ve noticed any of these, it’s worth getting it checked before the cold weather sets in deeper.

Can you repair a misted double glazing unit?

Yes – and you don’t need a brand-new window to fix it.

In most cases, we can replace just the sealed glass unit, not the whole frame or window. That means:

• Lower cost than full replacement

• Less disruption

• Quick turnaround

• Better energy efficiency

• A room that feels instantly warmer and more comfortable

It’s a smart fix that restores the comfort and clarity of your home without breaking the bank.

Winter is actually the best time to fix your windows

You might think it makes sense to wait until spring or summer, but here’s why winter is the ideal time:

✅ Save on heating bills – Failed units let out more heat than you think✅ Prevent further damage – Moisture build-up can lead to frame rot or mould✅ Enjoy the holidays – A cosy, mist-free home is the best kind of gift✅ Faster availability – Many wait until spring, so winter slots can be quicker

Imagine watching Christmas lights or New Year’s fireworks through a crystal-clear window instead of squinting through fog.

What makes Velux windows more vulnerable?

Velux windows are brilliant at letting in light – but because they sit on your roof, they get more direct weather exposure. More sun. More rain. More temperature swings.

That’s why we see more condensation issues in Velux units, especially in older or well-used homes. The good news? You can absolutely replace just the glazing – and we do it all the time.

Just like the East Lothian job, we measure up, install the new sealed unit, and your view is back, better than ever.

Worried about cost? Here’s what to know:

Replacing a sealed glazing unit is far more affordable than installing a whole new window. You get all the benefits — energy savings, insulation, and clarity — without the heavy price tag.

We also offer upgraded units for even better insulation, which helps cut down your bills long after winter has passed.

Don’t wait until spring to fix that foggy glass

It might seem like “just a bit of mist,” but it’s more than a cosmetic issue. It affects your comfort, your energy bills, and your home’s condition.

Whether it’s for your own peace of mind, guests coming for Christmas, or just the joy of sitting by the window with your favourite drink, a simple glazing unit replacement can transform how your home feels this season.

Clearer views, warmer rooms, and a cosier winter

Whether it’s watching snow fall, spotting Santa (no shame!), or just soaking in that New Year calm — a clear, clean window makes it all that much better.
