Hardwood vs Softwood Decking: What Most Buyers Miss

A guy walked into the lumber yard with me a few months back.

He picked up a board of pressure-treated pine. Then he picked up a board of Ipe sitting three feet away. Same size. Same job — hold up a deck for the next couple decades.

But one was $3.50 a foot. The other was $14.

He looked at me like I’d rigged the prices as some kind of joke.

I get this question more than almost any other in my shop. And honestly, most of what’s written about it online is garbage. Half the articles push the cheap stuff because that’s what most people end up buying anyway. The other half push exotic hardwood because it sounds fancy and makes for a better blog post.

Neither one is being straight with you.

So let me just tell you what I’ve actually seen. I’ve built decks with both kinds of wood. I’ve torn out boards that failed way sooner than they should have. And I’ve got a twenty-year-old Ipe deck two properties down from me that’s outlasted three separate pressure-treated pine decks on the same street.

That’s not a fluke. It’s just what these two materials do. Once you understand why, the decision gets a lot easier.

Quick version, if you’re in a hurry:

Softwood (cedar, redwood, pressure-treated pine) runs $3 to $9 a square foot installed. Lasts 10 to 25 years. Wants restaining every year or two.

Hardwood (Ipe, Cumaru, Tigerwood) costs more upfront — $12 to $25 a square foot. But it stretches out 30 to 75+ years. Mostly just needs occasional oiling, or nothing at all if you’re fine with it going silver-gray.

Softwood wins if you care about today’s price tag. Hardwood usually wins if you do the math over 20 years. Keep reading and I’ll show you exactly why.

Why These Two Woods Aren’t Even Playing the Same Game

Here’s something that trips people up: “hardwood” and “softwood” aren’t about how hard the wood feels when you knock on it.

They’re botanical categories.

Softwoods come from cone-bearing trees — pine, cedar, redwood, fir. The evergreen stuff.

Hardwoods come from broadleaf, flowering trees — oak, Ipe, Cumaru, Tigerwood.

What actually matters for your deck is what’s going on inside the wood at a cellular level.

Hardwoods have vessel elements — tiny pores running through the wood. They’re packed in tight with dense lignin. That’s what gives them their weight and their tight grain.

Softwoods don’t have those vessels. They rely on simpler cells called tracheids to do double duty — moving water and holding the tree up structurally. That’s part of why softwood is lighter, easier to cut, and soaks up water more readily.

That one structural difference is the root of almost everything you’ll notice as a deck owner:

• Density decides whether your deck dents when you drag a cooler across it or drop a grill lid.
• Tight grain determines how much water gets absorbed into the board — the whole reason softwood cups, checks, and splits over time.
• Natural oils and tannins in tropical hardwoods act like a built-in bug and fungus repellent. That’s the actual reason Ipe doesn’t need chemical pressure-treatment the way pine does.

If you want a number that makes this real, look at the Janka hardness scale. It measures how much force it takes to push a steel ball halfway into a piece of wood.

• Southern Yellow Pine: around 690 lbf
• Cedar: even softer, around 350 lbf
• Ipe: 3,510 lbf

That’s not a small gap. That’s five to ten times harder. It’s the difference between your dog’s nails leaving scratches and not leaving a mark at all.

Side by Side, No Sugarcoating

The Actual Wood You’ll Be Choosing Between

Ipe is the one everyone’s heard of. It earns the reputation.

I’ve seen Ipe decks push 40 to 75 years with barely any upkeep. That Janka number of 3,510 lbf means it shrugs off wear that would chew up a softer board.

The catch is weight and density. It’s brutal on saw blades. Brutal on drill bits. And you will pre-drill every single screw hole — or you’ll snap your fasteners trying to drive them in raw. I learned that one the hard way early in my career.

Cumaru runs almost as hard as Ipe. But it’s got a personality quirk.

In the first few months, rain pulls tannins out of the wood. You’ll get orange-brown runoff staining anything light-colored underneath it — like a stone patio or concrete pad. It stops eventually. But plan for it.

Tigerwood gives you that striped, dramatic grain pattern people love. It sits at a Janka rating around 2,160 lbf — still way harder than any softwood. It usually costs a bit less than Ipe too, somewhere around $9 to $13 a square foot for materials.

One thing I tell every customer working with these tropical species: use stainless steel or coated hardwood-rated fasteners, and pre-drill everything. Regular deck screws just snap against wood this dense. And mixing metals will corrode fast thanks to the natural tannins in the boards.

On the softwood side, Redwood and Western Red Cedar are the ones people pick when they want that warm, straight-grain look.

The heartwood resists rot naturally. The sapwood doesn’t. So that matters when you’re picking boards.

Price-wise they’re close — redwood runs $7 to $10 installed, cedar $6 to $9. Redwood tends to hold its color a little longer before it grays out. Both need a UV-blocking sealant every year or two, or you’ll watch them silver and check faster than you’d like.

Then there’s pressure-treated Southern Yellow Pine — the wood that built more American decks than anything else. Mostly because it’s cheap. $2 to $4 a square foot for material.

But here’s the thing nobody tells you upfront: all that rot resistance comes from the chemical treatment, and that treatment only goes so deep into the board. The second you cut an end or drill a hole, you’ve exposed untreated wood. That spot becomes a doorway for decay if you don’t seal it with an end-cut preservative.

What This Actually Costs You Over Time

This is where most articles quote you a price per square foot and call it done.

That’s the wrong number to make a decision on. What actually matters is what you spend over the years you own the house.

Over 10 years (installed cost plus maintenance):

• Pressure-treated pine: $5.50–$9 per sq ft
• Cedar and redwood: $9–$14 per sq ft
• Ipe and Cumaru: $14.50–$23.50 per sq ft (mostly upfront cost — maintenance is almost nothing)

Over 20 years, the gap starts closing:

• Pressure-treated pine usually needs a full board replacement around year 15–20, pushing total cost to $18–$26
• Cedar and redwood land similarly, $16–$24, with some partial board replacement mixed in
• Hardwood barely moves — $16–$26 — because you’re just oiling it occasionally, not replacing anything

By year 30:

• Softwood is usually on its second full deck surface, pushing total cost to $28–$45+
• Hardwood is often still on its original boards, total cost around $18–$30 — genuinely cheaper than softwood by this point, which surprises most people

The break-even point — where hardwood’s bigger price tag finally gets paid back — usually lands somewhere between year 15 and 22. It depends on your climate and how good you are about keeping up with sealing.

Selling in the next 5 to 7 years? Softwood’s lower entry cost wins, no question.

This your forever house? The math flips hard in hardwood’s favor.

One thing worth mentioning that catches people off guard — hardwood is heavy. Ipe weighs almost double what pine does. So your joist spacing needs to be tighter, typically 12 to 16 inches on-center instead of the 16 to 24 inches you’d get away with under softwood.

If you’re putting hardwood decking on top of existing softwood framing, get someone to check the load capacity before you buy a single board. Don’t skip this step.

The Maintenance Question — Be Honest With Yourself Here

This is the part where softwood quietly costs you more than the receipt ever showed.

A realistic softwood maintenance year looks like this:

• Check your fasteners annually
• Power wash every year or so
• Restain or reseal every 1 to 3 years — and I mean actually do it, because skipping it gets you visible graying, splintering, and checking within two seasons
• Expect to replace individual boards every 8 to 12 years as rot or bugs get to them

Tropical hardwood is a completely different rhythm:

• An oil application every year or two is optional and purely cosmetic — skip it and the wood just weathers to a silver-gray patina, it doesn’t rot or fall apart
• No resealing required for rot prevention, because the density and natural oils are already doing that job
• Every once in a while you might sand down some raised grain in a high-traffic spot. That’s about it.

Here’s the real difference that matters:

A hardwood owner who never touches their deck still ends up with a structurally sound deck that’s just changed color.

A softwood owner who never touches theirs ends up with actual rot and insect damage — real structural failure, not just a cosmetic issue.

If you already know yourself well enough to know you won’t keep up with a sealing schedule, that fact alone should steer your decision.

What About Sustainability?

This doesn’t split neatly along hardwood-softwood lines. It really comes down to where the wood was sourced.

FSC certification is the one signal that actually tells you a board was harvested responsibly. It exists for both categories.

Softwood tends to have a lighter footprint by default. Cedar, redwood, and Southern Yellow Pine mostly come from managed North American forests that regrow in 20 to 40 years.

Tropical hardwood needs more scrutiny. Ipe and Cumaru come out of South American rainforest ecosystems where trees take 60 to 100+ years to mature. Buying uncertified wood can genuinely support deforestation.

Ask for FSC certification or equivalent documentation before you buy tropical hardwood. A supplier worth buying from will hand it over without you having to push.

And don’t overlook this: a deck that lasts 50 years without being rebuilt has a smaller lifetime footprint than one that gets torn out and replaced three times over that same span — even accounting for the longer growth cycle of the raw material.

So Which One Should You Actually Buy?

There’s no single right answer here. Just the right answer for your situation.

Go softwood if:

• You want the lowest price to get started
• You’re planning to sell within 5 to 10 years
• You don’t mind DIY upkeep
• You like being able to stain or paint the deck to match whatever look you’re going for later

Go hardwood if:

• You’re staying put for the long run
• You’d rather not spend your weekends resealing anything
• You’ve got high-traffic spots like a pool deck or the main hangout area
• You want a deck that’s still solid when your kids have their own kids

My honest opinion, after years of building both:

If you’re staying in the house more than 15 years, hardwood is the smarter money move — not just the fancier one. The math genuinely favors it once you stop comparing sticker prices and start comparing what you’ll actually spend over 20 or 30 years.

If you’re not sure how long you’ll be there, softwood keeps your money more flexible. It doesn’t lock up cash in a board that’ll outlive your mortgage.

Whatever you pick, remember this — the framing underneath, the fasteners you choose, and whether you actually stick to the maintenance schedule will matter more in the long run than which species you went with.

Wood doesn’t fail because it’s the wrong wood. It fails because it got ignored.
