Shaw/Stewart Lumber Co

What Shaw/Stewart Lumber Co does

Shaw/Stewart Lumber Co. is an independent, privately held building materials distributor and custom millwork fabricator headquartered in Minneapolis, Minnesota, with a second location in Rochester, MN. Founded in 1886 as W.R. Shaw Lumber Co. and recognized as the oldest lumber company in the Twin Cities, the company serves residential builders and remodelers, commercial general contractors, and architects across the upper Midwest, offering commodity and specialty lumber, building supplies, fire-retardant lumber treatment, large-timber processing, custom millwork, and premium Marvin windows and doors through a dedicated Design Gallery.

The company's production backbone is a 30,000 sq ft AWI-certified custom millwork shop on its 18-acre Minneapolis yard, combining CNC milling and advanced 3D drafting with traditional craftsmanship to produce Custom and Premium Grade architectural millwork, including mouldings, decorative timber trusses, stair parts, columns, beams, and mantels in 8+ hardwood species. It maintains a 76-profile stock moulding catalog across 19 categories, 50,000+ board feet of premium hardwood inventory (including Accoya with 50-year above-ground warranty), FSC Chain-of-Custody certification since 2006, and AWI founding membership in the Quality Certification Program since 1996. The facility integrates millwork, large-timber processing, fire-retardant treatment, retail showroom, and Marvin Design Gallery on a single site, with a dedicated railway spur for inbound logistics.

Shaw/Stewart operates a relationship-driven, sales-led go-to-market model with no public pricing. Dedicated sales staff provide consultative selling, precision takeoffs, and 3D renderings for residential projects, while a separate commercial division with dedicated estimators, drafters, project managers, and fabricators serves healthcare, university, retail, hospitality, mixed-use, and multifamily general contractors with complete millwork packages spanning wood, metals, glass, solid surface, and quartz. Revenue is generated almost entirely through hardware/inventory sales (commodity and specialty lumber, branded millwork, Marvin-branded windows and doors) priced via custom project quotes, with no SaaS, subscription, or platform revenue component documented.

Expansion highlights6 records

Broad incumbents

• Boise Cascade: Vertically integrated manufacturer and distributor of engineered wood products, lumber, and building materials. Comparable in wood-products expertise and pro-builder relationships, though primarily a manufacturer-wholesaler rather than retail yard.
• Foundation Building Materials: Specialty distributor of building products including insulation, gypsum, and complementary categories. Adjacent competitor in the pro-builder channel with national reach and a similar mix of branded building product lines.
• US LBM: PE-backed national leader in lumber and building materials distribution with dozens of specialty dealer brands. Direct competitor in lumber and millwork distribution to builders, with far larger scale and acquisition-driven growth model.
• BMC Stock Holdings: Major regional and national supplier of building materials, millwork, and components to professional builders (now part of Builders FirstSource). Overlaps with Shaw/Stewart in lumber, components, and window/door distribution.
• Lansing Building Products: Specialty distributor of exterior building products (windows, siding, roofing, millwork) serving professional contractors across the U.S. Comparable product mix and customer base, though typically without on-site custom millwork fabrication.
• 84 Lumber: One of the largest privately held lumber and building materials dealers in the U.S. with 250+ locations. Overlaps with Shaw/Stewart in lumber, millwork, and pro-builder serving, but at significantly greater scale and geographic reach.
• Builders FirstSource: Largest U.S. supplier of building products, prefabricated components, and value-added services to professional builders. Overlaps with Shaw/Stewart in lumber, millwork, windows/doors, and custom builder services but operates nationally.
• ABC Supply Co. National wholesale distributor of roofing, siding, windows, and exterior building products. Competes with Shaw/Stewart on the exterior products category (JamesHardie, AZEK, TREX, Marvin) carried at its yard.

Direct peers

• Jaeger Lumber: Family-owned regional lumber and millwork supplier operating across New Jersey and the Northeast. Comparable in business model — lumber yard plus custom millwork shop serving builders and remodelers — though serving a different geography.
• Lampert Lumber: Regional family-owned lumber and building materials dealer serving Minnesota and the Upper Midwest with multiple yard locations. Directly comparable in scale, customer mix (builders and remodelers), and product breadth.
