Credentials & honors

Newman Lake, out on the east edge of Spokane County, is home base for Flatworks LLC, a concrete flatwork and paving contractor working Spokane Valley, Newman Lake and the county around them. Most of its work runs through other contractors and public agencies: the state shows public-works filings since 2018 for the City of Spokane, the Washington Department of Enterprise Services, the Town of Malden and several school districts, nearly always as a subcontractor.

Spokane Valley permits pulled on the licence tell the residential side of the story: driveway approach permits from 2015 through 2021 and a right-of-way permit in 2017, the kind needed when a driveway meets the street. The state insures the business under a concrete flatwork class and keeps a permanent yard or shop, which fits a crew that does slabs, approaches and paving rather than building. Public agencies on the record include Mead, Riverside and West Valley school districts, Spokane County Water District 3, Consolidated Irrigation District 19 and the Spokane Public Facilities District. Flatworks holds registrations in both Washington and Idaho, and the state lists Justin Glenn as a principal since 2010. Flatworks makes sense for a driveway, patio, approach or slab replacement in Spokane Valley or around Newman Lake, especially where the work touches the street and needs a city permit. Work tends to come through referrals and general contractors rather than advertising, so expect a conversation, not an online booking form. Concrete is the whole job here; framing, roofing or a full remodel belong with a different contractor. Concrete in Spokane follows the weather. Pours generally wait until nights stay above freezing in spring, and the stretch from late spring through early fall is when flatwork crews are busiest, with commercial and school jobs often packed into summer break. A homeowner who wants a new driveway or patio before summer does well to call in late winter, while schedules are still open. Fall pours are possible but get squeezed as frost returns, so leave room for a weather delay.
