When it comes to decking, there are two types of wood that stand out and create a long debate among homeowners: cedar vs pressure-treated decks.
Both have their own unique qualities that make them good choices for different reasons.
Cedar is a popular choice because it’s naturally resistant to rot and decay, while pressure-treated wood is a more affordable option that can last for many years with proper care.
So which one is the best choice for your outdoor project? Keep reading to find out!
Quick Verdict: Cedar vs Pressure-Treated
- Cost: Pressure-treated wood is the more budget-friendly option upfront, typically costing 30–50% less than cedar. Cedar costs more initially but can offer a better return on investment thanks to its natural durability and curb appeal.
- Lifespan: Both materials can last 25–40 years with proper care, but cedar holds up better in consistently wet or shaded conditions without chemical treatments. Pressure-treated wood has the edge in ground-contact applications.
- Maintenance: Cedar requires cleaning and resealing every 1–2 years to maintain its appearance. Pressure-treated wood is lower maintenance early on, but still benefits from periodic sealing to prevent cracking and graying over time.
What Is Cedar Wood?
Cedar wood is a type of softwood that comes from the cedar tree. It has a reddish-brown color and a distinctive smell that many people find appealing.
Cedar is naturally resistant to rot and decay, making it a good choice for outdoor projects such as decking.
It’s also relatively lightweight and easy to work with, making cedar decking a great choice for do-it-yourselfers.
Cedar Deck: Pros and Cons
If you’re looking for a wood decking material that has a natural look, cedar is a good option. The heartwood of the cedar tree is rot-resistant, and the wood doesn’t readily absorb moisture.
This means that cedar deck boards tend to lie flat and straight, and they have a lifespan of 15 to 20 years.
However, dimensional cedar lumber can deteriorate faster if it’s used for ground-level decks or shaded decks that are slow to dry out.
You also have to clean and reseal cedar decking every year or two to keep it looking its best. Even with proper care, though, cedar won’t look like new wood after 10 years.
Cedar is also softwood, which means it’s not ideal for stairs or decks where furniture gets moved around often. Western red cedar is a popular choice among homeowners.
Overall, though, cedar is a good choice for a natural-looking wood deck.
What Is Pressure-Treated Wood?
Pressure-treated lumber has been treated with chemicals to resist rot, decay, and insect damage.
The treatment process involves putting the wood in a pressure chamber and exposing it to high levels of pressure. This forces the chemicals deep into the cedar lumber or any other type of wood, making it much more resistant to the elements.
Pressure-treated decking is a good choice for outdoor projects because it’s durable and long-lasting. It’s also relatively affordable, which is another plus. Home improvements stores like Lowe’s or Home Depot sell fairly good pressure treated lumber.
Pressure-Treated Deck: Pros and Cons
Pressure-treated pine wood or southern yellow pine is a popular choice for decks and other outdoor projects, thanks to its affordability and long lifespan.
But not all pressure-treated lumber is created equal. Cheaper varieties of treated wood can contain a lot of moisture and shrink unevenly as they dry, leading to an unsightly deck that may also be structurally unsound.
If you’re looking for an inexpensive treated wood that will resist twisting and shrinking, look for a brand that carries a lifetime warranty. You’ll pay more upfront, but you’ll save money in the long run.
Cedar vs Pressure-Treated: Side-by-Side Comparison
| Factor | Cedar | Pressure-Treated |
|---|---|---|
| Cost | Higher upfront ($4–$8/linear ft) | More affordable ($2–$5/linear ft) |
| Lifespan | 15–20 years (up to 30+ with care) | 20–25 years (up to 40 with care) |
| Maintenance | Seal every 1–2 years | Seal every 2–3 years |
| Appearance | Rich, warm, natural tone | Greenish tint when new; grays over time |
| Best Use Case | Elevated decks, dry climates, high-end aesthetics | Ground-level decks, budget builds, high-traffic areas |

What We Recommend as Deck Builders
After building decks across the Knoxville area, here’s our practical take on which material makes sense for which homeowner:
- Choose cedar if aesthetics are your top priority. Homeowners who want a warm, natural look and are willing to commit to annual maintenance will be happiest with cedar. It photographs beautifully and adds real curb appeal.
- Choose pressure-treated if you're working with a tighter budget or need ground contact. For decks that sit close to the ground or in areas with heavy shade and moisture, pressure-treated wood is more practical and cost-effective.
- Don't skip the sealing. We see a lot of decks come in for repairs that could have been avoided with a consistent sealing schedule. Whether you go cedar or pressure-treated, sealing every 1–2 years is the single biggest thing you can do to extend your deck's life.
- Ask before you buy. Lumber quality varies a lot between suppliers and grades. A board that looks fine in the store can warp badly once it dries on your deck frame. We're always happy to point customers in the right direction before they commit.
At Riverview Decks, we’ve built decks with both materials in neighborhoods all across Knoxville, from raised decks on hillside lots to wide backyard platforms meant for entertaining.
Every project teaches us something new about how local weather, soil conditions, and homeowner habits affect how a deck holds up over time.
