Siwek Lumber & Millwork

What Siwek Lumber & Millwork does

Siwek Lumber & Millwork is a privately held, family-owned building materials retailer founded in 1933 by Joseph and Frances Siwek, currently operating three retail locations across Minneapolis, Jordan, and Le Seuer, Minnesota, supported by a 13-acre storage site and an 8,000 sq ft hardware store at the NE Minneapolis headquarters on Marshall Street NE. The company supplies construction lumber, treated lumber, OSB, CDX, insulation, gypsum board, specialty hardwoods (oak, maple, cherry, walnut, and exotics), redwood and cedar, roofing and siding products, composite decking (Trex, TimberTech, MoistureShield, Deckorators), pole building packages, and an 8,000 sq ft builder's hardware store carrying Milwaukee Tools, GRK Fasteners, Simpson Strong-Tie, and other fastener and tool brands through the Do-it Best cooperative. Its core differentiator is an on-site Custom Millwork Shop equipped with a Weinig moulder and saw mill capable of replicating historic profiles, fabricating custom doors and windows, and producing specialty wood items such as barn doors, corbels, mantels, and trim, serving historic restoration contractors and homeowners that big-box retailers cannot accommodate.

The business model is transaction-based retail and project-quote sales across multiple categories: physical storefront sales of lumber and building materials to contractors and homeowners, custom millwork fabrication priced by unit (e.g., barn doors from $400 base), pole building and garage package sales with free delivery, and e-commerce fulfillment through the Do-it Best cooperative (65,000+ SKUs with ship-to-store and direct-to-jobsite options). Go-to-market is sales-led with category-specialist representatives (Brad Gemlo for homes/additions, David Falconer for decks/siding/roofing, Paul Werner and Peter Wawrzyniecki for millwork, Scott Talbot for redwood/industrial, Cassandra Ledezma for Milwaukee Tools) supplemented by community-led engagement in NE Minneapolis through sponsorships of local organizations and active social media presence on Facebook and Instagram. The company serves DIY homeowners, professional contractors and builders, remodelers, historic restoration specialists, and industrial/manufacturing buyers requiring crating and packaging lumber, primarily across the Minneapolis-St. Paul metropolitan area and broader Minnesota market.

Direct peers

Strong comparable for the distributor/dealer side of Siwek's business serving contractors across multiple states.

• Lamperts: Family/independently owned Upper-Midwest lumberyard and building materials retailer operating across Wisconsin and Minnesota with comparable full-line product mix, contractor focus, and store footprint.
