Quick Answer
Okay, let’s get right to it. If money and long-term toughness matter most to you, go with pressure-treated wood. If you love that natural warm look and don’t mind doing a little more upkeep, go with cedar. That’s really the whole decision, boiled down.
There’s no “wrong” pick here. It just depends on what you care about more: your wallet or your view from the porch.
Key Takeaways
- Pressure-treated wood costs less than cedar, board for board.
- Cedar fights off rot and bugs on its own, with natural oils, no chemicals added.
- Pressure-treated wood is soaked in chemicals, so it needs time to dry before you stain or seal it.
- Cedar is lighter and easier to cut, but it dents easier too. Drop a hammer on it and you’ll see a mark.
- Both need sealing to last. Don’t let anyone tell you either one is “no maintenance.”
- Got a termite problem in your area? Pressure-treated usually wins that fight.
Many Asks Me This
I get this question more than almost any other. “Sam, should I go cedar or pressure-treated for my deck?” Friends ask me. Neighbors ask me. Readers email me about it too.
Makes sense why. These two are the go-to choices for decks across the country. Both have people who swear by them.
I’ve built with both, so I’m not just guessing here. My own backyard deck? Pressure-treated pine. I was watching every dollar back then, and it just made sense. But a few years back, I built a small deck for my neighbor using cedar. And man, the smell when you cut into fresh cedar boards? It’s amazing. Kind of warm and woodsy, almost like walking into a sauna.
But a nice smell doesn’t hold up your deck for twenty years, right? Let’s talk about what actually matters when you’re picking wood that has to deal with rain, snow, blazing sun, and your kids running across it every day.
What Pressure-Treated Wood Actually Is
Most pressure-treated wood you’ll find is pine. It goes through a machine that pushes chemical preservatives deep into the wood, not just on the surface. That’s the whole trick. The chemicals soak all the way through, so bugs and rot can’t get a foothold, even on the inside of the board.
I wrote a whole guide breaking this down if you want the nitty-gritty details: pressure treated wood pros and cons.
What Cedar Actually Is
Cedar, and I mean western red cedar specifically here, comes with built-in protection. It has natural oils and tannins inside it that bugs and fungus just don’t like the taste of. No chemical bath needed.
Is it perfect? No. I go over where cedar can let you down in my is cedar wood worth it piece. Worth a read before you commit.
Wood Deck Guide: Types, Costs & Best wood for deck

Let’s Talk Money
This is where most people make up their mind, honestly. Cedar can cost double a pressure-treated board, sometimes more, depending on where you live and the grade you buy. Multiply that across a whole deck, and you’re looking at a real difference.
Here’s a scenario. Say you’re building a 300 square foot deck. Going full cedar instead of pressure-treated could add a few thousand dollars to your total bill. That’s not pocket change for most of us.
If the budget’s tight but you don’t want to skip out on a solid deck, check out deck financing options or ways to finance a deck. That way you’re not stuck cutting corners where it actually matters, like the frame underneath. Some folks doing a bigger home project also look into home equity loans for renovations to cover it all in one go. And before you buy a single board, run your numbers through a wood calculator so you’re not guessing how much you actually need.
Which One Holds Up Against Bugs and Rot?
On paper, pressure-treated wins this one, hands down. Those chemicals are made specifically to stop termites, carpenter ants, and rot fungus dead in their tracks. If your area has bad termite problems, I’d steer you toward pressure-treated every time.
Want to know the difference between rot damage and termite damage? I’ve got you covered in termite damage vs wood rot. And if termites are already on your mind, take a look at drywood termites: spot, treat, and prevent and carpenter ants vs termites.
Now, cedar’s not defenseless. It does resist bugs and rot on its own. But it’s a natural defense, not a guarantee. I’ve seen cedar get soft and moldy in spots that never see the sun and stay damp all the time. So airflow under your deck matters just as much as the wood you pick.
Looks and How It Feels Under Your Feet
Cedar wins the beauty contest, no contest. It’s got this rich, warm color right off the truck, and it soaks up stain like nothing else. Pressure-treated wood usually shows up with a green or yellow tint that fades over time, and stain doesn’t always go on evenly, especially when the wood’s still fresh.
Walking on cedar just feels different too. Softer under your feet. And if you’re the one building it, you’ll notice cedar boards are a lot easier to carry around all day. Your back will thank you.
So Which Lasts Longer?
Here’s the truth nobody wants to hear: it’s mostly about how well you take care of it, not which wood you pick. I put together a full guide on picking and using the right product over at best deck sealer, and it works the same whether you went cedar or pressure-treated.
Skip the sealing, and cedar turns grey and dull within a year or two under strong sun. Skip it on pressure-treated, and you’ll get cracking and splintering way earlier than you should. Neither one takes care of itself. Anyone who tells you different at the lumber yard is trying to make a sale.
One Thing That Trips People Up: Timing
Here’s a mistake I made early on. Pressure-treated wood needs to dry out completely before you stain or seal it. We’re talking a few weeks, sometimes a couple months, depending on your weather. I learned this the hard way and wrote up the full process in 7 tips for staining pressure treated wood so you don’t repeat my mistake.
Cedar’s a lot more forgiving here. Since it’s not soaked in wet chemicals, you can usually seal it much sooner after it’s installed.
Trying to decide between oil-based or water-based stain either way? I broke that whole thing down in oil-based stain vs water-based stain.
What If You Want To Paint It A Solid Color Instead?
Some folks don’t want to see the wood grain at all, and that’s fine too. Painting covers up the natural look completely, no matter which wood you started with. I walk through that whole process in how to paint a deck. Need color ideas? Start with best deck colors for hot climates.
What Would I Actually Do?
If it were me building a regular backyard deck on a normal budget, here’s my honest pick. I’d use pressure-treated wood for the frame, the joists, the posts, everything hidden underneath. That part never sees the sun anyway, and rot resistance matters most right there.
Then, if my budget allowed it, I’d put cedar on top. The visible boards, the railings, the parts you actually touch and see every day. You get strong bones holding everything up, and a warm, natural look where it counts.
If the whole budget is stretched thin, pressure-treated top to bottom is still a great, proven choice. Go look around your own neighborhood. Bet you’ll spot pressure-treated decks that have held up just fine for fifteen, twenty years with basic care.
Common Questions People Ask Me
Is cedar more expensive than pressure-treated wood? Yeah, pretty much always. Cedar runs higher per board foot, sometimes a lot higher depending on the grade and your local supply.
Does cedar need sealing too, or does it protect itself? It needs sealing. Cedar resists rot naturally, sure, but without sealer, it’ll grey out and dry up in the sun just like anything else.
Which one’s better if I live somewhere really rainy? Pressure-treated usually has the edge in constantly wet spots because of the chemical treatment. But honestly, good drainage under your deck matters more than which wood you pick.
Can I mix the two on one deck? Absolutely, and lots of people do exactly this. Pressure-treated for the frame, cedar for the boards you see. It’s a smart, common approach.
Which one’s easier to work with if I’m doing it myself? Cedar, no question. It’s lighter and softer, so cutting and carrying it around is a lot less tiring.
Does pressure-treated wood really smell like chemicals? A little bit when it’s brand new, yeah. That smell fades away once it dries out and cures over a few weeks.
Bottom Line
There’s no single “winner” here. Go pressure-treated if your budget and bug resistance matter most. Go cedar if you want that natural beauty and don’t mind a bit more cost. Whichever one you pick, the real secret to a deck that lasts is sealing it right and keeping up with it every year. The wood is just the starting point.
