About Us
“

Your work goes beyond construction; it’s about transforming the lives and communities within those spaces.

Garco Construction is an excellent firm to partner with on the most challenging of projects. Their team is highly solution-oriented and endeavors to bring rapid solutions to the table to solve complex problems. The firm has an excellent safety record, and maintains solid subcontractor and vendor relationships. The firm treats owners (and neighbors) very well with a long-term perspective of fostering a collaborative relationship not only on the current project, but for the next.

Kyle Twohig Spokane County Senior Director of Public Works

I’ve been working with Garco Construction on very difficult projects since 2004. I have always been impressed with their professionalism, attention to detail, cost control and quality of construction. We always look forward to seeing Garco Construction bid our projects. They have never disappointed us.

I have worked on several Garco projects and my experience has been the same each time. Excellent company culture that really believes in delivering an exceptional product.

I have never worked with a more professional team that are accommodating, have passion for what they do, and create great relationships with their clients.
