Decking has grown from a commodity lumber category into a specialty that can carry a building material dealer through slow markets. One dealer that opened during the last recession found the category strong enough to keep the doors open in the first years, and decking-related products now account for about a quarter of its business. Growth ran 27 percent in 2016, 28 percent in 2017, 20 percent in 2018, 10 percent in 2019, and up 30 percent through the first eight months of 2020. Hidden fastener systems helped make that shift possible, and hidden fastener installation methods changed how decks look and how fast crews can build them.
Why Decking Became a Specialty Category
A traditional full-line lumberyard competes on price for framing lumber, plywood, and other commodities. Decking lets a dealer compete on selection, expertise, and design instead. The strategy that worked in metro Atlanta moved customers from generic treated wood to higher-margin alternative materials while building close relationships with distributors and manufacturers of composite and PVC decking.
Growth Numbers Behind the Category
- 27 percent decking-related sales growth in 2016
- 28 percent in 2017 and 20 percent in 2018
- 10 percent in 2019, a slower but steady year
- 30 percent growth through the first eight months of 2020
The pattern is the lesson: even in a flat housing market, the decking category outgrew the rest of the yard because buyers traded up from treated wood to composites and PVC. Those numbers make decking one of the few lumberyard categories that reliably grows double digits in a normal year.
Displays and Showrooms That Sell
Dealers that specialize built massive outdoor displays and in-store deck design showrooms. One location devotes about 800 square feet indoors to decking and railing displays, with outdoor space roughly double that; another pairs a 650-square-foot studio with a 1,280-square-foot exterior display that shows railing options, deck surfaces, and steel framing in cut-away. Customers can stand on the product before they buy it, which moves the conversation from price per board to the finished result.
Manufacturer and Dealer Partnerships
Dealers that sell alternative decking depend on manufacturers for training, samples, and marketing support. Manufacturer programs such as dealer day events keep showroom staff current on new products and give salespeople material to discuss with homeowners, and a close partnership with a leading brand can pull walk-in traffic that benefits the whole category.
Composite vs. PVC vs. Treated Wood
Three material families cover most residential decks. Pressure-treated lumber remains the low-cost entry point. Composite boards blend wood fiber with recycled plastic for a wood look with low maintenance. PVC decking is solid plastic, priced higher and offering the longest warranties and the most consistent color.
Cost and Lifespan Trade-offs
Prices vary by region and line, but the spread is consistent: treated wood runs $3 to $5 per square foot for materials, composites $6 to $12, and PVC $8 to $15. Lifespans follow the same order, with treated decks lasting 10 to 15 years before significant repair, composites 25 to 30, and PVC often 25 to 50 with manufacturer warranties to match. Color and texture options have expanded as well: embossed grain, two-tone finishes, and wide boards that mimic the look of dimensional lumber now show up in every manufacturer line, and samples in the showroom do more selling than any brochure.
| Material | Material cost per sq ft | Typical lifespan | Maintenance | Best fit |
|---|---|---|---|---|
| Treated wood | $3–$5 | 10–15 years | Staining every 1–2 years | Budget builds |
| Composite | $6–$12 | 25–30 years | Occasional washing | Most homeowners |
| PVC | $8–$15 | 25–50 years | Occasional washing | Wet and coastal areas |
Fastening and Installation Systems
The concealed screw-down method documented in Fine Homebuilding’s classic article on concealed screw-down decking remains the benchmark for hidden fastener installation. Hidden clips and screws remove fastener heads from the walking surface, which cuts snags, prevents rust streaks, and gives composite decks the clean look buyers pay extra for.
Framing and Structural Support
The deck surface is only half the build. Joists, beams, and posts carry the load, and the framing choice affects cost, height, and durability. Steel framing has moved from commercial projects into residential decks, and a display with a cut-away showing the steel structure underneath teaches customers why the frame matters.
Steel vs. Wood Framing
Steel framing resists rot, termites, and warping, and it eliminates the crown and twist that wood joists bring to the job site. It costs more than pressure-treated framing and requires different fasteners and cutting tools. On the commercial side, metal floor decking follows its own gauge and span rules, but the framing logic mirrors residential deck structure: the frame determines what the surface can do.
Joist Spacing and Live Loads
Residential decks are designed for a live load of 40 pounds per square foot in most jurisdictions, with joist spacing of 12, 16, or 24 inches depending on the decking product. Composite and PVC manufacturers publish maximum span tables for their own boards, and following those tables prevents the bouncy, sagging decks that generate callbacks.
Composite-Friendly Framing Details
Composite boards expand and contract with temperature more than wood, so manufacturers specify gap spacing at the ends and between boards. Framing that keeps boards out of standing water, leaves room for expansion, and uses the recommended fastener pattern protects both the warranty and the installers who stand behind it.
Contractor Programs That Drive Volume
Dealers sell decking twice: once to the homeowner and once to the crew that installs it. Programs that connect homeowners to certified contractors who buy their supplies from the dealer close the loop, and rewards programs that incentivize pros to spend more keep volume flowing through the yard.
Mergers have accelerated the trend. When a millwork distributor acquired the decking specialist, the combined company gained e-commerce muscle, access to new product lines, and a stronger foothold in decking, and it began merging business models, cultures, and marketing under two familiar flags while consolidating operations in one facility.
Certified Contractor Networks
A certified contractor list gives homeowners a trusted installer and gives the dealer a predictable stream of material orders. Contractors on the list get training, priority pricing, and early access to new products, which makes the network self-reinforcing as successful jobs generate referrals.
Rewards and Volume Incentives
Rewards programs work when the math is simple: spend thresholds, tiered discounts, and perks that pros actually use. Crews that install composite decking year round master the material’s expansion rules and fastener patterns faster than crews that treat it like wood, so dealer training that builds installer expertise pays off in fewer callbacks and better word of mouth.
Durability and Maintenance Across Materials
Maintenance is the sales conversation that closes deck sales. Treated wood needs staining and sealing on a schedule; composites and PVC need little more than occasional washing. Buyers who understand the upkeep difference before they buy rarely regret the upgrade. Repair is a different story: a gouge in a composite board usually means replacing the board, while a damaged treated wood board can often be sanded and refinished, so homeowners with pets and heavy furniture should factor repairability into the choice.
Cleaning and Seasonal Care
- Sweep debris and wash with mild soap and water twice a year
- Remove snow with a plastic shovel, never a metal blade
- Trim nearby vegetation so leaves and sap do not stain the surface
- Spot-clean mold and mildew with a deck-safe cleaner before it spreads
Wood Alternatives for the Traditionalist
Not every buyer wants plastic. Tropical hardwoods such as mahogany, meranti, and balau offer real wood grain with better rot resistance than domestic softwoods, and the durability of mahogany decking shows how these species compare with composites on lifespan and care.
Planning a Deck Project From Quote to Completion
A successful deck sale walks the customer from a showroom visit to a finished installation without surprises. Dealers that staff outdoor living experts and invest in display space close more of those sales at higher margins.
A Five-Step Sales and Build Sequence
- Tour the display with the customer and compare materials in person.
- Measure the site and confirm local code requirements for footings and railings.
- Quote material and labor separately so the homeowner sees where the money goes.
- Match the homeowner with a certified contractor from the dealer network.
- Schedule delivery around the build so boards arrive dry and undamaged.
Even well-built decks eventually show cracks and weathering, and restoring cracked, weathered decking returns a tired surface to service at a fraction of replacement cost. That repair work keeps customers coming back to the same dealer who sold them the original materials, which is how a decking specialty turns into a recurring revenue line.
