Why Our Clients Choose Us


Cost-Effective, Innovative Approach

High Quality Construction Management

Schedule, quality, safety and budget are tightly managed. Regular meetings with crews and clients keep our projects on time and on budget.


Permit & Regulatory Support

Washington State is highly regulated. If you’re moving dirt or building near a watershed your restrictions are even greater. We know what you can and can’t do and how to navigate the system to get your job approved and signed-off. 

No Project Too Big Or Too Small

Big or small, your project is important to us. In the world of construction there is no one size fits all. No two projects are ever the same in complexity or scope. As Whatcom County’s only full-service utility contractor, we pride ourselves in offering tailor-fit solutions that minimize cost and timeline.

From bulk material hauling to comprehensive land development projects and custom homes we have you covered.

Our cross-trained crews and expertise make us the ideal contractor to work with. We understand everything from what’s underground to how to build complex commercial buildings.

Every project is approached with a commitment to making sure it’s done right. This commitment ensures we stay within the initial budget, and that you’re 100% happy with the work performed.

Client Testimonials

These guys came in and knocked out a two-day water main job in less than a day and kept the price to the quote I was given. The guys were very friendly and professional and they cleaned up the mess to better than it was before they started! They made a potential nightmare way less stressful!

The job was done professionally in spite of terrible weather. Kyle was friendly and kept me apprised of progress on the job throughout.
