Quantum Construction has been serving Skagit, Island, San Juan, Snohomish, and Whatcom counties since 1984. We provide the best service in a wide scope of construction projects, ranging from commercial and industrial to custom residential and sustainable buildings.

Based in Anacortes, Quantum Construction was founded on the principles of quality, dependability and safety. Not only will we construct the highest quality projects for you at a reasonable cost, but you can depend on us to finish the project on time without exposing you to the risks of an unsafe job site. Nationally recognized for safety, Quantum creates an environment that is an asset to you, not a liability.

In January 2011, Quantum Construction joined SICBA’s Built Green program, a chapter of non-profit Built Green Washington. The focus of Built Green is to emphasize construction features that improve a building’s efficiency, making it more comfortable in addition to environmentally friendly. The flexibility of Built Green allows our clients to select from a variety of options to tailor a package that fits their tastes, specifications and budget. Please contact us to learn more!
