Our History
Central Washington's trusted civil infrastructure contractor since 1984.
Since 1984, Riddco has been the civil contractor Central Washington's telecom and power partners turn to for reliable underground infrastructure work. From directional drilling and vacuum excavation to conduit systems and surface restoration, we handle the work with the experience, the fleet, and the local knowledge it takes to do the job right.
Our Focus
Commercial civil infrastructure. We serve telecom contractors, power providers, and government partners building the underground systems Central Washington depends on.
Our Mission
Keep Central Washington's telecom and power builds on schedule with reliable directional drilling, vacuum excavation, and underground utility work.
Our Timeline
Four decades of Central Washington infrastructure
1984
The Beginning
Gary L. Riddle founds Riddco out of a small shop in East Wenatchee, Washington. The company starts with a simple principle: show up, do the work right, and earn your reputation one job at a time.
1989
Moving to Yakima
Riddco relocates to Yakima to have a centralized presence across Central Washington. The move puts the crews closer to the telecom and power projects that become Riddco's core work.
2009
A New Generation
Brett and Darcy Armstrong — Gary's daughter and her husband — take ownership of Riddco. They continue growing the company's relationships with major telecom and power partners while staying true to the principles Gary built it on.
