David and his crew provided excellent service. My home is now more comfortable, allergen free, and my power bills have dropped dramatically. He has also done exterior repairs and I'm very pleased with all the work. I highly recommend him to other homeowners.

Dave Trentlage is incredibly professional and knowledgeable, forthright, fair, and responsive. He is also passionate about energy remediation and has taken the time and effort to educate himself in every way possible probably much beyond the demands of his job. If you want complete and total energy remediation in your home, including all the ancillary work that entails -- carpentry, trim work, etc. done absolutely right, call them. And our power bills are already much lower.

Compliments to Dave Trentlage and his team. They did an excellent job with getting a new window installed. I was very pleased with their punctuality, professionalism, and with the cleanup.
