"Not only was Teresa professional and knowledgeable, informing me of the details of the tests and recommendations for what fixes can easily be done myself or with simple fixes. But gave detailed notes of affordable and recommended options for more involved fixes. Additionally, Teresa accommodated my disability well, and discovered two minor gas leaks, aiding me in calling the utility and getting immediate repairs. I'd highly recommend 5 lakes to anyone looking to improve their home energy use, or prevent airflow problems."

We are a full service high performance insulation company. We also perform home performance audits that include infiltration testing and infrared imaging.

"Lee's team of insulation specialists did a phenomenal job of spray foam insulating a very, very small crawl space in our home (as well as some boxsills). We have had several construction professionals in our home recently, as we are considering a major renovation to our house, and they have all commented on how well done the job is, and how amazed they are that insulation specialists were able to access such a small space. The team arrived on time, did their work quickly, and the administrative team was very communicative, personable, and kind. We'd highly recommend Duerst to others!"

If you’re concerned about the minimal bump to your electricity consumption, you can opt for smart tint, which doesn’t require electricity to work.

A couple of the best ways to find a reputable energy auditor is by determining whether they are HEP-certified by the Building Performance Institute (BPI). This certification will help you narrow down your list of professionals to the most qualified pros with the most relevant experience.
