If you feel cold air coming through your windows during the winter or warm air entering during the summer, your windows may have air leaks.

Drafty windows are a common problem for homeowners in Knoxville and East Tennessee, especially in older homes or homes where windows were not installed correctly.

At MI Homesiding & Roofing, we provide professional drafty window repair in Knoxville, TN, helping homeowners stop air leaks, improve comfort, and reduce energy loss.

Since 2004, I’ve worked on exterior remodeling projects throughout Knoxville. Many drafty window problems are not caused by the window itself, but by gaps in the surrounding trim, siding, or insulation.

Our goal is to find the real source of the air leak and repair it properly.

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.

Signs Your Windows May Be Drafty

Drafty windows can create uncomfortable indoor conditions and increase heating and cooling costs.

Common signs include:

If you notice any of these signs, your windows may need professional inspection.

Cold air near windows during winter

Warm air entering during summer

Curtains moving slightly near closed windows

Higher heating and cooling bills

Rooms that feel colder near window areas

Common Causes of Drafty Windows

Many drafty window problems are related to installation issues or exterior damage around the window.

Here are some of the most common causes.

Failed Caulking Around Windows

Exterior caulking helps seal the edges of a window from outside air.

Over time, Tennessee heat, humidity, and storms can cause caulking to crack or shrink, allowing air to pass through.

Replacing deteriorated caulking is often the first step in fixing drafty windows.

Gaps Between Window Frame and Wall

In many homes, the problem is not the window itself but the exterior materials surrounding it.

Rotten wood trim, damaged siding, or missing aluminum wrap can allow outside air to enter the home.

Because I specialize in siding installation and exterior repairs, I always inspect the surrounding structure when diagnosing drafty windows.

Poor Window Installation

Some drafty windows are the result of improper installation.

If the window was not installed level or properly sealed, gaps can develop over time that allow air infiltration.

Correcting these issues requires careful inspection and professional sealing methods.

Our Drafty Window Repair Process

very repair begins with a detailed inspection to locate the source of the air leak.

Our repair process may include:

Air leak inspection
Identifying gaps around the window frame and exterior trim.

Sealing and insulation repairs

Window adjustment
Ensuring windows open, close, and lock properly.

Our goal is to improve comfort inside the home and reduce unnecessary energy loss.

When Window Replacement Is the Better Option

In some cases, drafty windows may need to be replaced instead of repaired.

Replacement may be recommended when:

FAQs

What causes windows to feel drafty?

Drafty windows are often caused by cracked caulking, missing insulation, or gaps between the window frame and wall.

Can drafty windows be repaired?

Yes. Many drafty windows can be repaired by sealing air leaks and repairing trim or insulation around the window.

Do drafty windows increase energy bills?

Yes. Air leaks force your HVAC system to work harder, increasing heating and cooling costs.

Should drafty windows be replaced?

Not always. In many cases repairs can solve the issue without replacing the entire window.

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.
