Interior Tech is a specialty contractor with a focus on fire/smoke/egress design, glass, acoustic operable partitions, space division alternatives, and security. We provide design & budget assistance, specifications, design details, installation, and technical support. Serving the Pacific Northwest since 1947, we are dedicated to providing our customers with proven solutions and unmatched customer service.

Given the uniqueness of our niche product and design areas, we provide highly specialized design, construction, and owner support to ensure each project’s success. We are uniquely positioned to bring value to the design and construction team.

We have built a strong foundation in Oregon and Washington, growing from just a few employees in 1947 to one of the largest contractors of our type in the US. Our founder, Arnold Fredrickson, was known for the same brand of customer service and work ethic that we strive for today. Our success is a result of our dedication to customer service and strong relationships we’ve built with our business partners and customers. We serve clients throughout the Pacific Northwest from our offices in Seattle, Portland, Spokane and Vancouver B.C.
