Industrial Support Service LLC.

The public-works record is the clearest picture of what this business does. Beyond the ferries, the city and WSDOT, the agencies on file include Washington State University and its Spokane campus, Central Washington University, Big Bend Community College, the City of Walla Walla, Spokane County Public Works, the Pend Oreille County Public Utility District, Energy Northwest and the state Department of Enterprise Services. Nearly all of that work came as a sub rather than a prime. The state lists John Schmidlkofer and Jefferi Schmidlkofer as principals since 2010. That shape suits a general contractor or facility manager on a municipal, campus or utility project who needs a support sub with prevailing-wage experience, and anyone coordinating trades on a larger commercial job around Spokane, Spokane Valley, Cheney or Airway Heights. A homeowner planning a new house or a single-trade remodel will likely find a better fit with a residential builder or a dedicated trade contractor, since this firm's work leans toward coordination and public jobs. Before any support contractor starts, pin down exactly which tasks are theirs and which belong to other trades, so nothing falls in the gap between scopes. Ask who handles cleanup and debris removal each day and at the end, and how change orders get priced and approved in writing before extra work begins. On public or commercial jobs, confirm how prevailing-wage paperwork will be filed. Ask what warranty covers their portion of the work and who you call if something needs correcting after the job closes.
