“I spoke with Mark Lee of Better World Builders this morning 1/30/2024 about installing an egress window in my basement. He took the time to walk me through the installation process and gave me alternative suggestions which will safe me money. I really appreciate him taking the time to go over this with me and that he focused on the best solution to my situation. I feel extremely confident using his company for building projects in the future.

“When we moved into our new home it was drafty and cold. We almost replaced a bunch of expensive windows, but decided to have a BWB perform a blower door test first. The test data showed that our windows were fine, but that we had several areas with poor insulation and air sealing. BWB prepared a three tiered approach to improve the home, and identified approximate energy savings for each tier.

After completing the first tier, which included spray foam insulation and air sealing, we saw a 30-35% reduction in our blower door test air leakage values. Incredible.

The crew that completed the work was professional and treated our home with care and respect. The work was completed on time and they went the extra mile in a few areas.

I highly recommend better world builders.”

“Better World Builders has been wonderful to work with. Their team always responds to us with speed, thoroughness, patience, competence, and friendliness.

Shawn and Issac came all the way to Buchanan to perform an extensive energy audit this fall on our old 1930s house with 1950s and 1990s additions. Their reporting on the problems, the data, and potential improvements was clear and detailed. It is a great baseline for later confirming that the improvements succeeded.

They go above and beyond to answer all of our questions and to address any concerns. With my background in architecture and affordable multifamily development, my questions are many and deep diving. Fortunately, Mark and Shawn respond promptly and patiently to them all as we plan the improvements together. It is clear to me that they understand this field of work, they respect the homes, and they care about their customers. I am grateful to have connected with the Better World Builders team.”
