Dsi Construction Inc.

The state insures Dsi under workers'-comp classes for drywall installation, taping and finishing, plaster and stucco, insulation and soundproofing, and building repair, alongside project managers and estimators. That matches the services the company advertises: modular walls and wall panels, including DIRTT systems, plus exterior finishes and green building. Public-works filings name the City of Spokane, Eastern Washington University, Washington State University, Spokane County, Spokane Housing Authority, and the Central Valley, Mead, Cheney and Moses Lake school districts, nearly always as a subcontractor, with apprentices on the job. A 2026 commercial tenant improvement permit in Spokane Valley fits the same pattern. The state lists Jeff Miller and Tracy Miller as principals since 2018, and the crew runs in the 51 to 75 range. Dsi fits commercial tenant improvements, office and classroom interiors, and agency projects that need a prevailing-wage sub with a long filing history. Work tends to come through referrals and repeat general contractors. A homeowner after a whole-house remodel or an exterior-only job is outside that line, since the shop's focus is interior walls, ceilings and acoustics on commercial and public buildings. Drywall work splits sharply by size. Patching a cracked ceiling in an older South Hill house or finishing a basement room is a small-crew job, and a local residential drywaller or handyman is usually the right call. A full office build-out, a school wing, or a space that needs sound control between units is a different trade in practice: steel framing, acoustical ceilings, scheduling around other trades, and estimating at scale. For those, a commercial interiors sub working under your general contractor makes sense, and it's worth asking the GC which drywall firm they plan to bring in.
