Building scientists Jeff and John Tooley have been a committed father-and-son team diagnosing homes for moisture and energy problems for decades. In their combined experience, they have come to understand that the difference between a home that works and one laden with moisture and energy problems often lies in how well it's framed. They offer simple recommendations for stopping air and putting an end to all the moisture problems that come with severe air leaks - all tasks best done by the framer.
