ABOUT US

Unlike traditional excavation companies, JMA Construction is reshaping Seattle’s construction landscape by doing what others won’t - taking the time to get it right. While competitors rush to underbid, we roll up our sleeves and dive deep into every project, working shoulder-to-shoulder with general contractors to propose real solutions. Our combination of meticulous planning, genuine relationships, and regulatory know-how makes us the go-to partner for developers who want results, not excuses.

WHY WE DO
WHAT WE DO

We exist because construction demands more than just moving dirt - it requires investing in people and building lasting partnerships. We take collective ownership of our results, going all-in to get it done. We’re setting new standards by bringing deep knowledge, authentic relationships, and a solutions-first mindset to build what matters.
