Air Sealing Services

Air leaks from gaps and cracks are commonly found in buildings throughout Southeastern Wisconsin and Northern Illinois. Together these areas of air leakage can lead to indoor air quality problems, comfort issues, and high energy bills. In fact, ENERGY STAR reports that all the leaks in an average home can add up to the equivalent of leaving a window open all year long! 

At Diversified Insulation, we offer comprehensive air sealing services for both residential homes, commercial buildings, pole barns, and more. Our team uses FLIR thermal imaging cameras before every air sealing project to accurately find areas of temperature differences and air leaks in order to provide a reliable and long-lasting solution. Our team typically finds air leaks in:

  • Forced air ductwork

  • Windows

  • Doors

  • Exterior walls

  • Electrical fixtures

  • Box sills

  • Rim joists 

Why Air Sealing Matters 

When air leaks aren’t properly sealed, not only will unconditioned outdoor air infiltrate your home or business, but your building will also be susceptible to energy loss throughout the year as well. This air movement will cause numerous issues, including:

  • Drafty rooms

  • Inconsistent temperatures

  • Increased wear & tear on your HVAC system

  • Ice dams during the winter

  • Moisture problems

  • High energy bills

  • And more!

Air leaks also hinder the effectiveness of insulation, allowing outside contaminants like moisture, dirt, pollen and pests inside, ultimately diminishing the indoor air quality of your home or business.

The Benefits of Combining Air Sealing & Insulation 

At Diversified Insulation, we always recommend air sealing when making insulation upgrades to your home or business, especially in vulnerable areas like attics, basements, and crawl spaces. While air sealing offers protection from air movement, it won’t do much for heat transfer, and vice versa. However, when combined, the efficiency, comfort, and indoor health benefits of these two services will be enhanced and last longer.

Professional Air Sealing in SE Wisconsin and Northern IL 

Unfortunately, most air leaks aren’t visible with the naked eye, which is why it’s important to work with an experienced contractor, like Diversified Insulation. We’ve been helping home and business owners make crucial improvements to their buildings since 2013, and are third generation insulation contractors in the Burlington area. We start every insulation and air sealing project with an on-site inspection and will even walk you through available incentives to make your upgrades more affordable. 

"Mike was very professional and energetic. I'm very happy with the work he did and would recommend your company for future business." - Mark M. April, 2021


"I was extremely impressed with the team at Diversified Insulation! After my initial call for an estimate, Mike was able to come to my house within 2 days. He was very thorough and extremely knowledgeable. He used FLIR thermal sensing technology to see where the temperature variations were throughout the house. He explained his recommended process very clearly and I was emailed an estimate that same day." - Chris L. March 2021


"We had a great experience with Diversified Insulation. Calling into the company we spoke to Crystal who got us set up immediately to get an estimator to our house that day. At our home, I met Mike Voss who was prompt, professional, and was very through with his help and support. He also gave solid recommendations on how to move forward with the issues we were having. After his help, he contacted us after to check in on things and I had told him I was having a hard time finding a roofer that would help us with what we needed. He then went above and beyond giving us a recommendation on who to go with —-who is also giving us a very quick turn around time. Without the help and support of Mike...we wouldn’t be able to move as quickly as we are with finding a solution to our issue. Thanks for your help, Mike. Highly recommend asking for Mike when calling in." - Helen X. March, 2021


"His thermal camera to show where the cold areas were and confirmed my suspicion that there were some insulation issues that could be fixed. He gave me several options to pursue and how we could correct the problem. Mike was very good to work with, very professional and friendly. I would recommend using this company again as it was a very positive experience." - Joel W. December, 2020

Couldn't be happier. From start to finish we were impressed with their quality, price, communication and cleanliness. We were on a strict schedule and they were able to accommodate no problem. If I could give more stars I would. I have and will be continuing to refer them with confidence to anyone, in my eyes I wouldn't go with any other company.

Diversified was highly professional and super helpful along our project. They were super patient in answering all my questions and concerns. The crew was fast, efficient, and cleaned up great. Heck- they even put my garbage cans away for me when they were done. Who does that?! Thanks!
