Credentials & honors

Service upgrades and panel work turn up again and again in Marko Electric's permit history: a new 200-amp panel in a Spokane Valley garage, free-standing 400-amp services in Spokane and Davenport, a new service in Mead. The Nine Mile Falls electrical contractor also handles remodel wiring, generator hookups and repairs after fire or storm damage, on homes and commercial spaces across Spokane County and beyond. It holds a Washington registration and an Idaho electrical contractor license.

Recent permits show the spread of the work. There are kitchen and bath remodels in Spokane Valley and Newport, a new home in Medical Lake and an office and gym remodel in Spokane. A fire-damaged area was rewired in Medical Lake, and kitchen can lights were replaced after a tree came through a roof in Spokane Valley. Smaller jobs show up too: a garden-post circuit in Valleyford, a sign circuit in Deer Park, apartment units re-energized. Washington insures the crew of four to six under electrical wiring in buildings. Between 2016 and 2023 the shop filed public-works jobs for the state Department of Fish and Wildlife, the City of Spokane, SNAP and Seattle City Light, usually as a subcontractor. Much of Marko Electric's work comes through general contractors and repeat customers rather than advertising, so a homeowner usually reaches the shop by referral or through a builder. It fits a household planning a panel replacement or full service upgrade, a remodel that needs new circuits, or rewiring after property damage. Prevailing-wage public jobs suit it too. The state lists John Marko as a principal since 2014, the year the business was established. In Washington nearly all electrical work beyond swapping a fixture or device needs an electrical permit and an L&I inspection, and in the City of Spokane and Spokane Valley the same holds for service changes, new circuits, generators and remodel wiring. A new panel or service also means coordinating with the utility for disconnect and reconnect. Expect the electrical contractor to pull the permit in its own name and schedule the inspection; that record follows the house when it sells and matters to insurers after a fire or storm claim.
