I was standing in the middle of our backyard last November, holding a piece of paper that felt like a punch to the gut. The contractor—a nice guy who spent twenty minutes measuring our back door—had just handed me an estimate for $18,420 to build a 16x20 raised deck. Eighteen thousand. For some wood and screws.
Before we get into how we didn't pay that, a quick heads-up: this post contains affiliate links. If you decide to buy through them, I earn a commission at no extra cost to you. We only recommend the plans and tools we actually dragged out into the North Carolina mud to build this thing ourselves. Full disclosure, we're still learning, but we're learning with better tools now.
She looked at the quote, looked at the mud pit where our 'future outdoor oasis' was supposed to be, and then looked at me. 'We could buy a used truck for that,' she said. 'Or, we could buy a whole lot of lumber and a new miter saw and still have money left for a vacation.' And that was it. The decision was made. We weren't going to hire it out. We were going to build it, even if it meant our neighbors got a free show of us arguing over joist spacing for the next three months.
The $18,000 Reality Check
He’s the one who usually pulls the trigger on these projects, but I’m the one who has to figure out if the stairs are actually going to meet the ground. When we realized that a contractor was out of the question, the panic set in. We aren't architects. Our previous experience was basically a storage shed that took three weekends instead of one. A deck is different—it’s high up. If a shed falls over, your lawnmower gets a dent. If a raised deck falls over, you’re having a very bad day.
We spent December 2025 researching. The biggest cost in that $18k quote wasn't the lumber; it was the labor and the 'peace of mind' of a professional design. We realized if we could find a blueprint that was already engineered for safety, we could cut that cost by 70%. That’s when we stumbled onto TedsWoodworking. Having 16,000 plans sounds like overkill until you realize you need a very specific 16x20 layout that accounts for a sliding glass door and a slight slope in the yard.
Why Good Plans Are Better Than Good Intentions
I’ll be honest—I wanted to just wing it. I figured, how hard can it be? You put some posts in the ground, you lay some boards across them, and you’re done. She, being the sensible one, pointed out that I’ve never once measured a room and gotten the same number twice. She insisted on a real plan with a cut list.
This is where we actually saved the first few thousand. Using the detailed material lists from the deck plans, we were able to order exactly what we needed from the local lumber yard in one go. No 'oops, I forgot five more 2x10s' trips to the big box store. If you’ve seen our TedsWoodworking Review, you know we’re big fans of anything that keeps us from driving back and forth to town four times a day.
We ended up spending roughly $4,280 on materials, including the pressure-treated lumber, the concrete for the footings, and a fancy hidden-fastener system she insisted on because she 'hates seeing screw heads.' Even with the cost of the plans and a new impact driver, we were still sitting at a savings of over $13,000.
The Battle Against North Carolina Red Clay
If you live in rural NC, you know that our soil isn't actually soil. It’s a prehistoric brick material designed to break shovels. We started digging the footings in January 2026. According to the International Code Council, your footings have to be below the frost line—and even though it doesn't get crazy cold here, the county inspector doesn't care about your excuses.
He spent three days wrestling an auger that tried to dislocate his shoulders every time it hit a rock. I spent those three days checking the layout with a string line and a level. This is the part no one tells you about DIY: it’s 10% building and 90% moving heavy things and sweating in the cold. We learned the hard way that our yard has a 4-inch drop we didn't notice until the first two posts were in. We had to pull them, re-dig, and start over. Stubbornness, remember? It’s our only real skill.
Framing: Where 'Measure Twice' Actually Matters
By February, we were ready for the framing. This is the 'lego' phase of the project, or so I thought. Hanging the ledger board—the big piece of wood that attaches the deck to the house—is the most nerve-wracking thing I’ve ever done. You’re literally drilling giant holes into your home's foundation. If you mess this up, you get water damage, or worse, the deck pulls away from the house during a BBQ.
We followed the plan's instructions for flashing and lag bolts to the letter. This isn't the place to get creative. We used high-quality galvanized hardware because the humidity here in North Carolina will eat cheap metal for breakfast. Pro tip: Always check the Forest Products Laboratory guidelines for wood treatment if you're worried about rot—it saved us from buying the wrong grade of lumber for the support beams.
I remember standing on a ladder, holding one end of a 16-foot 2x10, while she tried to hammer the other end into a joist hanger. It was 48 degrees, misting rain, and I’m pretty sure we both said things we didn't mean. But when that beam slid into place and the level showed it was dead-on? That’s a better feeling than any contractor’s 'thank you' note.
The Moment We Almost Quit (The Joist Incident)
Every project has a 'dark night of the soul' moment. Ours was on a Tuesday evening in March. We had just finished installing all the joists—the ribs of the deck—and I stepped back to admire our work. Something looked... off.
She grabbed the tape measure. 'Honey,' she said, her voice way too calm. 'Why are these spaced at 24 inches on center?'
The plans explicitly called for 16 inches. I had gotten into a rhythm and just... kept going. Because we were using composite decking (the 'fancy' stuff), the joists needed to be closer together to prevent the boards from sagging. I had to spend the next four hours unscrewing every single joist hanger and shifting them. I sat in the dirt and almost told her to just call the contractor back to finish it. She just handed me a Gatorade and told me to get back to work. That’s the tag-team energy that keeps this house standing.
It reminded me of when we did the $600 DIY chicken coop build. We made the same kind of 'autopilot' mistakes there, too. You’d think we’d learn, but apparently, we need to do everything the hard way at least once.
The Final Tally: Where Did the Money Go?
We finished the last of the railing on April 10th, 2026. Just in time for the North Carolina spring to hit full force. Here is the actual breakdown of what we spent versus that $18,420 quote:
- Lumber and Decking: $3,150 (Pressure-treated frame + composite boards)
- Hardware and Concrete: $640 (Bolts, hangers, screws, and 12 bags of Quikrete)
- Permits and Inspection: $165 (Don't skip this—it makes the house easier to sell later!)
- New Tools: $325 (A decent miter saw and a laser level)
- The Plans: $67 (A drop in the bucket compared to what they saved us)
Total Spent: $4,347
Total Saved: $14,073
That is fourteen thousand dollars that stayed in our bank account because we were willing to be tired for a few months. We didn't just get a deck; we got the confidence to start the next project. Actually, I think I saw her looking at plans for a workshop yesterday. God help me.
Is DIY Right for Your Deck?
Look, we aren't saying everyone should go out and build a 10-foot high raised platform. If you're afraid of heights or you don't know which end of a hammer to hold, maybe start with a garden bed. But if you’ve got a bit of grit and a partner who doesn't mind holding the other end of a heavy board, you can absolutely do this.
The key for us was having a roadmap. We didn't have to guess if the structure was sound because the engineering was already done for us in the blueprints. If you're looking to start your own backyard transformation, I can't recommend TedsWoodworking enough. It gave us the confidence to stop being 'the people who talk about building things' and finally become the people who actually build them.
Now, if you’ll excuse us, we have a $14,000 savings account to go stare at while we drink a beer on our brand-new, perfectly level, DIY deck.
