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!

I tapped Choice Home Remodeling for a project involving exterior doors. I spoke to the service manager, Lonnie, who was very helpful and accommodating in scheduling the work. Lonnie called me a few days later to inform me he could have the techs out two weeks earlier, which was greatly appreciated.Tim, the installer manager, and Brian arrived for the service call. From the beginning, they were very polite and professional, and upon speaking to them, I knew they were very knowledgeable and competent. Their work was performed with great precision in a timely manner. I wholeheartedly recommend Choice for any of the numerous services they provide.
Don our salesman was great. Prices are competitive. Got windows and spouting done. Great installation.
