What Capital Lumber does

Capital Lumber Company is a privately held, third-generation family-owned wholesale distributor of specialty building materials, founded in 1948 in Phoenix, Arizona and now headquartered there. The company distributes natural and engineered wood products, lumber, composite and PVC decking, siding, trim, railing, fasteners, and related specialty building materials to lumber yards, home improvement centers, building materials dealers, and industrial customers across the Western United States. Its portfolio spans more than 50 supplier brands, including Huber Engineered Woods (ZIP System, AdvanTech), Azek/TimberTech, LP Building Products, Simpson Strong-Tie, and others, organized across decking, engineered wood, siding/trim, railing, and fastener categories.

Capital operates ten regional distribution facilities in Phoenix AZ, Chino CA, Healdsburg CA, Oxnard CA, Sacramento CA, Donald (Portland) OR, Tacoma WA, Boise ID, Salt Lake City UT, and Denver CO, with on-the-ground warehousing ranging from roughly 40,000 to over 120,000 square feet under cover and yard footprints of 6 to 18 acres. The company runs a decentralized operating model in which each branch functions as an autonomous business unit, empowered to customize programs, delivery options, and purchasing arrangements for local customers. Revenue is generated through product sales on a quote-based, contact-driven pricing model with flexible delivery and purchasing arrangements, and the company is privately held by the Gaskin family under President Scott Gaskin. Growth has been pursued through a combination of greenfield facility openings (most recently Boise in 2023 and Oxnard in 2022), facility relocations and expansions (Donald, OR in 2025; Sacramento in 2020; Chino in 2018), and selective acquisitions of regional distributors and product-line specialists (Humphrey Lumber, Snavely, JM Thomas, All-Coast, James Plywood, Capitol Plywood).
