Why Choose The Knotty Lumber Co. for Dimensional Lumber?
Locally Sourced, Sustainably Harvested
We take pride in offering both domestic and exotic hardwoods with integrity and transparency. Our domestic lumber species—including Black Walnut, Hard Maple, Cherry, and Ash—are responsibly harvested from well-managed North American forests. These woods are locally sourced to minimize transportation impact and support regional forestry networks. For exotic hardwoods such as Padauk, Purpleheart, Wenge, and others, we work with trusted global partners in South America and Africa. These boards are locally stocked in Canada and undergo the same rigorous quality control as our domestic products, giving you beautiful, ethically sourced lumber ready to ship when you need it.
Precision-Milled for Quality and Consistency
Each board we ship has been kiln-dried and surfaced to meet the expectations of professionals and passionate DIYers alike. Our surfacing process ensures flat, smooth, and defect-free surfaces that reduce prep time and improve results. Boards are precisely milled for uniformity in thickness and width—critical for tight joints, clean glue-ups, and consistent finishing. Whether you’re crafting furniture, building cabinetry, or framing custom interiors, you’ll notice the difference in every cut and every pass through your jointer or planer. Dimensional lumber makes the difference when quality matters most.
Bulk Discounts & Contractor Pricing Available
If you're working on a commercial job site, building repeat inventory, or just need a truckload of premium hardwoods—you’re in the right place. We offer volume-based pricing and contractor discounts on dimensional lumber to help you scale your builds affordably. Whether you’re a custom millworker, cabinet shop, contractor, or designer, we’ll work with you to meet spec, stay on budget, and deliver on time. Our team is happy to provide quotes for large orders and can help match your lumber selection to your production schedule, without compromising on consistency or grain quality.
Our Selection of Dimensional Lumber for Sale
Sizes, Grades, and Species Available
We stock a broad range of premium hardwood species, both domestic and exotic, to suit virtually any application. Choose from Black Walnut, Cherry, Maple, Ash, White Oak, Sapele, Padauk, Purpleheart, and more—each hand-selected for stability, grain quality, and visual appeal. Boards are available in standard hardwood lumber thicknesses like 4/4 (approximately 1” thick) and 8/4 (approximately 2” thick), measured before surfacing. These fractional terms are part of the industry’s quarter-sawn system, and allow you to select thickness that matches your joinery or build specs.
You can also select between S2S (Surfaced Two Sides) and S4S (Surfaced Four Sides) formats. S2S boards are planed flat on the face sides but retain rough edges—perfect for custom trimming or jointing. S4S boards are planed on all four sides and arrive fully prepped and squared, ready to assemble. These options allow you to balance flexibility and convenience based on your shop setup and tools.
Custom Orders and Special Requests
Looking for matched grain, longer lengths, extra-wide boards, or a unique cut? We've got you. Our team has direct access to thousands of feet of inventory and can fulfill special orders quickly. Whether it’s resawing, wide-belt sanding, or sorting by color tone—we're happy to accommodate your requests. Just reach out and we’ll quote you based on availability and lead time. We’re makers too, and we understand how the right board can transform a design or save hours in the shop.
Applications of Dimensional Lumber
Residential and Commercial Construction
Builders, framers, and architects use our dimensional hardwoods in everything from premium framing and finish carpentry to exposed ceiling details and feature walls. These boards are ideal for fine woodworking as well as architectural installs where visual consistency and structural integrity matter. With bulk order options and fast shipping available across Canada and the U.S., we’re your reliable partner for builds that require both beauty and durability.
Furniture Making and Custom Projects
Our surfaced hardwoods are trusted by furniture makers who demand quality they can see and feel. Whether you're building a one-of-a-kind live edge table, custom cabinetry, shelving, or solid wood countertops, you'll find the performance and consistency you need. Kiln-dried lumber ensures stability and reduces movement post-assembly, while S4S boards let you get right to work without a trip to the planer. Your creativity deserves a material that works with you—not against you. For finishing tips, check out our guide on dimensional lumber prep and finish techniques.
Outdoor Projects & Framing Applications
While hardwood is traditionally used indoors, several of our species—including Sapele and White Oak—offer excellent weather resistance when sealed and maintained correctly. Our customers have built everything from pergolas and outdoor kitchens to modern fencing using our dimensional stock. If your project includes framing, posts, or structural elements, let us help you choose a species and format that meets both aesthetic and performance goals in outdoor conditions.
