Mainstream Electric LLC.

The business traces back to a predecessor licence, Mainstream Electric Inc, first issued in 2002. The state insures its workers under plumbing and sewer cleaning, HVAC installation and repair, and building wiring, with a crew in the 51 to 75 range. Recent permits run from Spokane and Spokane Valley out to Colbert, Mead, Chattaroy and Colville: 200-amp panel replacements, a new range circuit, a new service, a generator inlet, and an overhead mast and aerial run from a barn to a shop in Medical Lake. In 2013 it worked as a subcontractor for the Spokane Housing Authority. The state lists Todd and Elaine Damschen as principals since 2022. This is a large residential service outfit rather than a commercial or industrial electrical contractor. It suits a household that wants one company for panels, EV chargers, furnaces, water heaters and drains. The company advertises 24/7 emergency and same-day service, a maintenance membership, flat-rate pricing, and a set of written guarantees including a one-year labor warranty with manufacturer parts coverage. It also says its work is never subcontracted. Around Spokane, the furnace and heat pump circuits pile up in early fall, when people realize the old system won't make another winter. Booking that work in late summer gets the electrical and HVAC side done before the first hard freeze, when emergency calls crowd schedules. Rural jobs with overhead runs, masts and ground rods are easier in dry months, before frozen ground and snow load complicate trenching and service drops. A generator inlet is worth adding ahead of winter storm outages, not during one.
