Since 1986, we have completed more than 2,000 building and remodeling projects in Corvallis and surrounding areas.

G. Christianson Construction uses advanced framing techniques that reduce the amount of wood needed and increase insulation while remaining structurally sound. On our new projects we use raised heel trusses to increase attic insulation near the edges of your roof. On our remodel projects we air seal penetrations in the walls we have opened, and our designers use passive solar design best practices.

What our Clients are Saying

“The client greatly appreciated the clear and detailed estimate and the professionalism shown in it. In addition, the inclusion of a project completion timeline, and one that seems reasonably rapid, was well received by the client. While your proposal was higher than the other bid received, the thoroughness and items mentioned above, provided the client with confidence that there is a reasonable reason for the higher price. The clients are seriously considering your bid as they see a lot of benefits to working with a company of your size, experience, and thoroughness.”
