What Causes Foggy Windows in Your House?

If your windows look foggy every day, it’s not the weather – it’s the windows. One of the most common questions we hear is “what causes foggy windows?”.

The Primary Cause of Cloudy Windows

what causes foggy windows

Those cloudy windows that have showed up on your home aren’t going away on their own. This phenomenon occurs when the seal that connects the main panes of glass cracks. This allows moisture to infiltrate between these panes, creating that uniquely unpleasant cloudy or milky look.

One of the main causes behind foggy windows is that the windows were never a high-quality product, and the seals were very weak. This often occurs as the homebuilder used what experts call “builder grade windows” – that simply aren’t meant to last.

One of the factors that exacerbates this is if the windows sit in direct sunlight. This causes the frames to expand and contract over the course of day, putting stress on the seal. Over time, the seal breaks and the window fogs. While generally, cloudy windows in your home generally appear after the five-year mark, in some cases, we’ve seen them show up even earlier.

Oftentimes cloudy windows are leaking as well – learn more about windows leaking cold air right here!


What to Know about Defogging Windows

First and foremost, it’s important to know that cloudy windows aren’t dangerous – even if they are extremely unsightly. However, you have options to resolve this problem. Our teams are experienced in both defogging windows and replacing them.

I would give Choice 10 stars if I could. The folks at Choice Home Remodeling have replaced all 31 of the windows in our house over the past year. They are incredibly professional and deliver an outstanding final product. The replacement windows look better than the originals and I get compliments on them all the time! The inside temperature of the inside glass on a 55 degree day has improved by 8 degrees! I am looking forward to seeing what the differential is once the weather turns cold. Their pricing is fair and the quality is second to none. I recommend them 1000%.
We absolutely love the new door we just had installed from Choice! We had such a great experience with Choice from start to finish. Tim was great and helped us pick out the perfect door for our home and didn't try to sell us the most expensive model and was honest, not pushy. Everyone we came in contact with was friendly and professional and the work was top notch.
I bought my windows from them. Everyone one was so nice and professional. Christie was very helpful. Thank you, will use again for other projects
So pleased with our bathroom renovation by Choice Home Remodeling! Alyssa Hayes did an excellent job in designing a functional and attractive way to best utilize our small space. Our kids are thrilled to have their own sinks! Alyssa patiently guided us through the design choices, made recommendations and outlined the construction process. The construction phrase was very timely, and Ken Brown was available for any questions and kept us informed of the schedule and what part of the project was happening when. I was very impressed that the job was finished very close to the scheduled completion date. The Choice staff and subcontractors were all respectful of our space and did a thorough job.
