Cedar sits in the middle of the material decision, better natural rot and insect resistance than pressure-treated pine without the upfront cost of composite. It's a real, established choice in this market, not a niche one, the deepest local deck competitor we researched runs cedar as one of its three core service lines.
Cedar contains natural oils and compounds that resist rot and insect damage on their own, which is why it doesn't go through the pressure-treatment process pine does. That's a real advantage for anyone who'd rather not have a chemically treated surface underfoot, and it's part of why cedar decks are commonly cited as lasting around 20 years with proper upkeep.
"Without chemical treatment" doesn't mean "without maintenance." Cedar still needs periodic oil-based sealant to hold its color and keep moisture from working into the grain, and Jonesboro's humid summers and heavy seasonal rain mean that sealant breaks down faster here than it would in a drier climate. Left unsealed, cedar grays out and loses some of its natural resistance over time, it won't rot as fast as untreated pine, but it isn't maintenance-free either.
Cedar decking installs run $30-47 per square foot, in between pressure-treated pine ($25-50) and composite ($35-70). Full size-based breakdown on our cost guide page.
Cedar decking isn't sold as one uniform product, it's graded, and the grade affects both looks and price. Clear or "Vertical Grain" grades are effectively knot-free, giving a smooth, uniform, higher-end appearance, and cost the most. Select Knotty is the highest grade of knotty cedar available, tight, attractive knots rather than loose or missing ones, combining a warmer, more rustic look with the same manufacturing standard as clear grades underneath. Standard Knotty grades cost less still and show more visual variation board to board. None of these grade differences change the wood's structural rating or rot resistance, they're a cosmetic and cost decision, not a durability one.
Cedar's advantages are in the decking boards themselves. Footings, posts, beams, and guardrail requirements follow the same code regardless of what material sits on top, per the state-adopted 2021 IRC. Framing members touching soil or in persistent ground contact still need to be pressure-treated or an approved ground-contact-rated material, cedar's rot resistance is real but isn't rated for direct ground contact the way treated lumber is.
Pressure-treated pine costs less upfront ($25-50 per square foot installed versus cedar's $30-47) because the treatment process, not the wood species, is what gives it rot resistance. Cedar's resistance is natural, which is why a lot of homeowners are willing to pay more for it, no chemical treatment underfoot, plus a warmer color and a real aromatic quality pressure-treated pine doesn't have. The honest tradeoff: pressure-treated needs less-frequent sealing in some climates, but in Jonesboro's humidity both materials need attention closer to the shorter end of their typical windows, cedar isn't a lower-maintenance choice here, it's a different-character choice at a similar total cost of ownership once you account for its own sealing schedule.
See our new deck construction page for the full footing-to-guardrail process, or composite decking if low-maintenance matters more to you than natural wood.
Most cedar decks need resealing every one to two years in a humid climate like this one, closer to annual than the two-to-three-year window pressure-treated lumber can sometimes stretch to, depending on sun exposure and how much rain the deck takes on directly.
Shade actually raises the maintenance bar, less direct sun means slower drying after rain, which is exactly the condition that encourages mildew on any wood surface, cedar included. A shaded cedar deck needs closer attention to sealing and occasional cleaning than one that gets full sun.
Cedar costs less upfront but needs recurring sealant and labor to maintain. Composite costs more upfront and largely skips that recurring cost. Which wins out depends on how long you plan to own the house and how much upkeep you want to take on yourself versus pay for.
