A Family-Owned Semi Truck Shop
Emerald Fleet Services keeps semi trucks moving across the Greater Seattle area — high-quality shop repairs, mobile on-site service, and full custom builds, all from one family-owned shop in Sumner.
Built on uptime, trust, and hard-earned skill
Emerald Fleet Services is a family-owned semi truck repair shop in Sumner, Washington. We were built for the owner-operators and drivers who need a repair partner they can actually count on — and we work with fleets that want the same thing.
Our value is simple: high-quality, trustworthy shop repairs, supplemented by the flexibility of on-site mobile assistance to reduce downtime. When you can't come to us, we bring the shop to you. And when you want more than a repair, the same crew builds trucks from the frame up — custom engine builds, engine swaps, air ride, flooring and full custom builds.
Whether it's a full heavy-duty engine rebuild, a DPF and emissions problem, or a breakdown on the side of the road, we treat every rig like it carries our name — because keeping you running keeps us in business.
