O.C. Cluss Lumber

What O.C. Cluss Lumber does

O.C. Cluss Lumber is a privately held, family-operated building materials supplier and professional installation services provider headquartered in Uniontown, Pennsylvania, founded in 1918 by Otto Charles (O.C.) Cluss and now operating as part of Builders FirstSource following a 2025 acquisition. The company runs four physical pro yards and distribution centers across Pennsylvania (Greensburg, Uniontown), Maryland (Oakland), and West Virginia (Fairmont), supplemented by a Fox-Cluss Glass Company division in Lemont Furnace, PA that handles commercial contract glazing and architectural aluminum. Its product portfolio spans lumber, plywood, building materials, roofing, siding, windows, doors, mouldings, millwork, insulation, and countertops (via a Vangura partnership), while its Cluss Professional Installation Services subsidiary delivers contracted installation across kitchens, baths, roofing, siding, insulation, windows, decks, and related categories.

The company serves two primary customer segments in roughly equal strategic emphasis: professional contractors and builders (served through pro yards with charge accounts, per-job monthly billing, fast computer-aided blueprint takeoffs, and free next-day jobsite delivery via boom truck fleet), and homeowners (served through the Uniontown showroom with free in-home measuring, computerized kitchen and deck design, and access to in-store financing). A secondary commercial construction segment is served via Fox-Cluss Glass for storefronts, curtain walls, specialty glass, and architectural aluminum. Revenue mechanics are predominantly transactional point-of-sale materials sales plus service contracts for installation; pricing is not publicly disclosed, though estimates and design consultations are offered free of charge as customer acquisition tools.

The go-to-market is sales-led and direct-to-consumer in parallel, leveraging a $9 million in-stock inventory for immediate pickup or delivery, knowledgeable outside sales staff providing jobsite consultation, and a Vendor Alliance Program with at least 15 manufacturers (including Andersen, Owens Corning, James Hardie, BlueLinx, and Vangura) that drives referral pipelines. Marketing channels include phone-based estimate scheduling, walk-in showroom engagement, and an organic social media presence across Facebook, LinkedIn, and YouTube. The company maintains a network of tenured kitchen designers (with 15-40+ years of individual tenure) and is fully licensed and insured in all three operating states.
