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.

Window Replacement – Many homeowners take these foggy windows as a sign they should just replace the whole thing. Newer, top-quality windows will look better, be more energy efficient and come backed with a lifetime warranty. At Choice Home Remodeling, we primarily recommend OKNA Vinyl windows for all new replacements we perform. This high-end vinyl brand earns our endorsement as the best window for home renovation.

Price: Between $700 and $800 to replace the old window with a top-of-the-line new model.

We just had 4 windows replaced and Jay the installer did an A+ job. I’ve had numerous jobs done by Choice and they’ve always been top notch with kind and courteous people from start to finish.
Always quality products, amazing service and follow through! I've used Choice Home Remodeling, Inc. for several projects and will continue to use them as needs arise. Highly recommend them!
Can't say enough positive things about Choice! We have entrusted them with many home projects over the years, including shutters, an indoor French door, and a sliding glass door on our back deck. Our salesman, Evan, has been our go-to guy for every project. He completes quotes/estimates in a timely manner, answers questions thoroughly, and follows up after the work is done. Their quality of work is top-notch, and their pricing is very fair. We appreciate everyone there for their kindness and great workmanship. It's nice to have a company you can rely on time after time. They have a great showroom too - it’s always beneficial to see the products in person.
We have used Choice Home Remodeling a couple of times this past year. Had a new screen and entry door installed and had some our upstairs windows replaced this week. Outstanding service and craftsmanship. We look forward to our downstairs windows being replaced. We plan on changing at all of our windows and was excited when we told that we can do them in phases. I/We highly recommend Choice Home Remodeling!
