Trinity Gate has been installing, repairing, and maintaining automated security gates across Washington since 1979, with crews serving properties from Bellingham south to the state border and east across the mountains. That broad service area is backed by decades of hands-on experience working with gate systems across a wide range of properties and conditions.
Our office is open Monday through Friday, 8am to 4pm. Call 425-881-3554 to reach us directly.
King County is one of Trinity Gate’s primary service areas, with residential, HOA, commercial, and industrial gate projects spanning the Eastside, Seattle, and communities throughout the southern part of the county.
Our King County service area includes:
The type of gate work varies across the county. Eastside communities account for a significant share of our residential and HOA projects, while the southern King County corridor brings more industrial and commercial work. Those properties often require heavier-duty operators, higher cycle ratings, and more advanced access control systems.
Pierce County is effectively on our doorstep from our Enumclaw office. Buckley, Bonney Lake, Sumner, and Orting are neighboring communities where our crews work regularly for gate repair, installation, and maintenance.
Our Pierce County footprint extends across the broader county as well:
Pierce County skews toward industrial and commercial gate work. Properties in this area often involve higher security requirements, heavier traffic volumes, and more demanding equipment specifications than residential installs.
We serve Snohomish County for automated gate repair, installation, and preventive maintenance across a wide range of property types.
Cities we cover in Snohomish County:
Whether the job is a commercial facility, an HOA-managed entrance, or a residential property, our crews bring the same in-house installation standard and UL325 compliance to every Snohomish County project.

Example areas we serve include Ellensburg and Cle Elum on the I-90 corridor, Moses Lake and Wenatchee over the pass, Bellingham to the north, Olympia and Bremerton on the sound, Yakima and the Tri-Cities, and Vancouver to the south.
