If you notice condensation or a cloudy appearance between your window panes, your window likely has a failed seal.

Foggy windows are a common problem for homeowners in Knoxville and East Tennessee, especially with older double-pane windows.

At MI Homesiding & Roofing, we provide professional foggy window repair in Knoxville, TN, helping homeowners restore window clarity and improve energy efficiency.

Since 2004, I’ve worked on many homes where homeowners believed they needed full window replacement. In many cases, the issue was simply a failed seal or moisture trapped between the glass panes.

They completed a major home exterior project for us including replacing and painting our siding as well as replacing our roofing and gutters. They did an excellent job and we began getting compliments immediately from our neighbors about it! Mel was very communicative and proactive, listened to our questions and ideas, and took care of things in a timely manner. His team was always professional and the work is just superb!  We not only recommend MI Homesiding, we will be using them again for future projects ourselves.

 Trustindex verifies that the original source of the review is Google. I found MI Homesiding & Roofing through their YouTube channel and called with a few questions about siding. Even though I’m not located in Tennessee and wouldn’t be hiring them directly, they answered the phone right away and took the time to answer every question in detail. They provided specific, helpful information and even assisted me in finding a contractor in my area. It’s rare to find a company so willing to help someone who isn’t even a local customer. Awesome people, excellent service, and truly knowledgeable. Thank you so much!

 Trustindex verifies that the original source of the review is Google. We are very happy with MI Homesiding's workmanship and dedication to achieve the best results for our Hardyboard residing. Mel answered our calls promptly; addressing and tending to any question we had. As with any home renovation, we ran into minor issues when we removed the siding the flashing was old and damaged. MI siding was more than happy to give us a fair estimate and replace the flashing to the siding. Porta-potty & dumpster were dropped off immediately prior to process, and removed with equal precision. Workers were diligent maintaining a safe & clean work area; cleaning remnant debris on last day. We recommended MI to our neighbors, and are having them back to caulk & paint. They did an excellent job at a fair price.

What Causes Foggy Windows?

Most modern windows use double-pane or insulated glass units (IGU).

These windows are sealed with insulating gas between the panes to improve thermal performance.

When the seal fails, outside air and moisture enter the space between the panes, causing the foggy appearance.

Common causes include:

Knoxville’s humid climate can accelerate seal failure in older windows.

aging window seals

exposure to extreme temperature changes

poor window installation

long-term moisture exposure

Signs of a Failed Window Seal

Homeowners often notice several symptoms when a window seal fails.

These include:

If the condensation is between the panes, the seal inside the glass unit has likely failed.

fog or condensation between glass panes
cloudy or hazy window appearance
moisture that cannot be wiped away
reduced insulation performance
higher heating and cooling costs

Can Foggy Windows Be Repaired?

In many cases, foggy windows can be repaired instead of replaced.

Possible solutions include:

A professional inspection helps determine whether repair or replacement is the better option.

Our goal is always to recommend the most practical and cost-effective solution for the homeowner.

Frequently Asked Questions – FAQs

What causes condensation between window panes?

Condensation between panes usually means the insulated glass seal has failed.

Can foggy windows be repaired?

Yes. In many cases the insulated glass unit can be replaced without replacing the entire window.

Do foggy windows affect energy efficiency?

Yes. When the seal fails, the insulating gas escapes and the window loses thermal performance.

Should foggy windows be replaced immediately?

Not always. Some windows can be repaired depending on the condition of the frame and glass unit.

Hidden Damage Policy

If rotted framing, failed flashing, or moisture behind the trim is discovered during the project, we stop and document the problem with photos. We explain what we found and why it matters, then provide a written Change Order before moving forward.

We never set a new window into a wall we have not inspected.
