At Washington RetroFoam, we insulate the walls of existing homes. About half the homes in the Pacific Northwest over 40 years old have no insulation in their walls. Others have highly degraded insulation. We use a foam that is harmless to touch, non-volatile, and Class One Fire Rated. We can typically insulate a 2,000-square-foot home in less than five hours for less than $4,900, usually driving a payback in less than three years.

I am a retired residential architect with thirty years experience running my own company. I focus exclusively on consultations, which are great for: Initial feasibility, Cost estimates, DIYers. My consult includes the re-design of one floor of your house. I produce a hand sketch drawn to scale that contractors can use for a cost estimate.

Architecture for high performance single-family remodels, additions and new construction.

Green building expertise tailored to the needs of homeowners living in the Northwest. 

I've spent the last 30 years of being a general contractor specializing in green building. I help home owners plan their green remodeling or new home projects; help builders build their green building & remodeling capacity; and work with architects, helping with speciific projects. I leave in north seattle but work on projects throughout North America. I was a general contractor for 40 years & am a 4th generation contractor. I'm one of the founders of the NW EcoBuilding Guild.
