ABOUT B-LINE CONSTRUCTION, INC.
Built Here. Growing With Our Community.
Since 1991, B-Line Construction has been part of the Shelton community. What began as a local excavation company has grown into a full-service construction business serving homeowners and property owners throughout Mason County and surrounding communities, including Belfair, Allyn, Union, and Hoodsport.
We’ve grown, our services have expanded, and the industry has changed—but our roots haven’t.
We’re still local. We’re still hands-on. And we still believe in doing the job right.
From 16-Year-Old Summer Employee to Owner
B-Line’s story is closely tied to the people who have helped build it. The company’s current owner started working at B-Line when he was just 16, spending his summers learning the business and working alongside the people who built the company. Years later, after gaining experience in the construction industry and staying connected to B-Line, he eventually took ownership. Today, he’s leading the company into its next chapter—with a firsthand understanding of where B-Line came from and the community it serves.
Experience You Can Count On
Today, B-Line provides a wide range of services, including septic system design and installation, advanced septic systems, septic pumping and inspections, excavation, land clearing, site preparation, road building, tree removal, demolition, and custom home construction. Our ability to handle many phases of a project in-house means fewer moving parts for our customers and one experienced team helping bring everything together.
A Local Company Built on Relationships
After more than 35 years in Mason County, we’ve learned that construction is about more than getting the job finished.
It’s about communication, quality workmanship, treating people and their property with respect, and taking pride in what we leave behind. We’ve built our reputation through hard work, word of mouth, and relationships with the people and businesses in our community. That trust is something we work to earn every day.
Proud of Where We Started. Excited About What’s Ahead.
B-Line has been building in Shelton for more than 35 years, and we’re proud of the foundation that was laid here.
As we continue to grow, our goal is to stay true to the values that got us here: hard work, quality craftsmanship, honest communication, and taking care of our community.
Because this isn't just where we work. This is home.
Whether you need septic services, excavation, land clearing, site preparation, or a contractor for your next construction project, we’re proud to put more than 35 years of local experience to work for you.
