“Carl’s house avoids 19 tons of CO2 every year compared to a code house. If all houses throughout the entire United States did that, it is possible to slow down carbon emissions to the point that we can slow down global warming and eventually, hopefully, reverse it.”

“I love working with the Christianson crews. They are thoroughly professional and incredibly detail-focused. They kept the worksite perfectly clean and tidy, and never skimp. Our screened porch (2015) and remodeled kitchen (2020) are our favorite, most-used, rooms in the house.”
Sandra Bean, Corvallis
