Framing: Gary Labrie Carpentry, Weare NH
Gary started framing with his father as a teenager, and has been in the industry ever since. Gary is very passionate and his workmanship and attention to detail is unrivaled. When we first approached Gary about constructing air tight homes he was a bit apprehensive about it, but as we worked together identifying air paths through the air envelope, we devised simple techniques to address each. In the end we are able to consistently create homes with predictable air leakage results and achieve our goal of less than 1ACH@50PASCALS.

Renewables: Homes for a Lifetime LLC, Weare NH
When Homes for a lifetime decided to make the jump to Zero Energy Homes, They decided they could have better control over the entire system if they installed the roof mounted PV in house. By going this route they had better control over the installation workmanship, as the installers are more familiar with home construction and understand what it takes to ensure a quality installation. This also insures that there are licensed electricians handling every aspect of the electrical component installation, from grounding clamps to PV panel installation, not just at the electrical panel.
