The Quick Answer
Before you hire any decking contractor, check these 5 things first:
- Check the papers. Make sure they are licensed and insured. Ask to see it, don’t just trust their word.
- Ask about the permit. A good deck builder always pulls building permits from the city. Never let anyone skip this.
- Never pay 100% upfront. A fair payment schedule is broken into steps, not one big payment on day one.
- Ask to see old work. Real references and real photos, not just a phone screenshot.
- Get a real written estimate. Not a number on a napkin. A real contract with a materials breakdown and labor costs written out.
Now let me tell you why these five things matter so much. I learned some of this the hard way.
My Big Mistake
A few years back, I hired a guy to build a deck for my cousin’s house. He seemed nice. He talked fast, had a truck with a logo on it, and gave me a price right there on the spot, standing in the driveway. No paper, just a number in his head.
I should have asked more questions. Instead, I said yes because the price was low. Big mistake.
He asked for half the money before he even bought the wood. That part was okay, half is normal. But then things got slow. He showed up late. Some days he didn’t show up at all. When I asked about a building permit, he said, “Don’t worry about it, we don’t need one.” That was a red flag, and I didn’t listen to it.
The deck got built, but it was not good. The structural framing was weak in one corner. You could feel it bounce a little when you walked on it. My cousin had to pay another contractor to fix it later. That cost more money than if we had just done it right the first time.
My friend told me something after that, and it stuck with me: “The cheapest price today can be the most expensive mistake tomorrow.” He was right.
The 5 Main Things You Must Know
1. Check the Papers (License & Insurance)
This is step one, and don’t skip it. Every good deck builder should be licensed and insured. This is not just a piece of paper. It protects you.
If a worker gets hurt on your property and the contractor has no insurance, guess who might have to pay for it? You. That is why insurance matters so much.
Here’s what I do now. I ask for the license number, and I look it up myself. Most cities and states let you check this online in a few minutes. If a general contractor gets upset when you ask for this, that tells you something too.
2. The Permit Rule (Never Build Without the City Knowing)
A deck is not just some boards in your yard. It’s a structure attached to your house. That means it usually needs a permit, and it needs to follow local building codes.
Some contractors skip this step to save time or money. They might tell you, “We don’t need a permit for this small deck.” Sometimes that’s true for very small, low decks. But for most deck construction projects, especially anything attached to the house or higher than a step or two, you need a permit.
Why does this matter so much? Two reasons:
- Safety. Permits mean someone checks the work. A final inspection makes sure the structural integrity is solid and the deck won’t collapse under weight.
- Selling your house later. If you sell your home and the deck was never permitted, this can cause big problems. Buyers and appraisers ask about this. It can even lower your resale value or stop a sale completely.
If a contractor tells you to skip the permit, walk away. That’s not a shortcut. That’s a warning sign.

3. The Payment Plan (Never Pay 100% Upfront)
This is one of the biggest lessons I learned. Never, ever pay the full price before the work is even started. A trustworthy deck builder breaks the payment into a schedule, tied to real progress on the job.
Here is a payment schedule that is common and fair for most deck construction projects:
| Milestone | Typical Payment % | What Should Be Done |
|---|---|---|
| Signing the contract | 10% – 20% | Contract signed, permit process started |
| Materials delivered | 30% – 40% | Pressure-treated wood, screws, and hardware bought and on-site |
| Framing complete | 20% – 30% | Structural framing built and passed rough inspection |
| Final walkthrough | 10% – 20% | Final inspection passed, everything looks and feels right |
If someone asks for 100% of the money before they even buy the wood, that’s a big red flag. Good contractors don’t need to do that, because they already have credit with their material suppliers.
4. Ask to See Their Old Work (Checking References)
Don’t just trust a nice smile and a good sales pitch. Ask for references. Real names, real phone numbers, real addresses if possible.
Even better, ask to see a deck they built at least one or two years ago, not just last month. Why? Because new wood always looks nice. You want to see how the deck holds up after some rain, some sun, and some time. That tells you the real quality of their work.
I always ask this now: “Can I call two people you’ve worked for in the last two years?” A good worker says yes without any problem. Someone with something to hide will make excuses.
5. Get Everything on Paper (The Detailed Contract)
This is where my cousin’s story went wrong. A number on a napkin is not a contract. A real written estimate should include:
- A full materials breakdown: how much pressure-treated wood, screws, joist hangers, and other hardware, and the price for each
- Labor costs, listed clearly, not just one big number
- The full project timeline, with a rough start date and finish date
- Info about the workmanship warranty, meaning what happens if something breaks or fails after they leave
- Details about who is pulling the building permits, and who pays for them
- The full payment schedule, matching the milestones we talked about above
If a contractor won’t put this in writing, that tells you they might not stand behind their own work.
Good Contractor vs. Red Flag Contractor
Here is a simple table I wish I had before I hired that first guy.
| Behavior | Good Contractor | Red Flag Contractor |
|---|---|---|
| License & Insurance | Shows you proof right away | Says “trust me” or avoids the question |
| Permits | Pulls the permit, follows local building codes | Tells you to skip the permit |
| Payment | Uses a payment schedule tied to progress | Asks for 100% of the money upfront |
| References | Gives you real names and addresses | Gives excuses or vague answers |
| Estimate | Written contract with a full materials breakdown | Quick number, nothing on paper |
| Communication | Shows up on time, answers your calls | Hard to reach, shows up late or not at all |
| Warranty | Offers a clear workmanship warranty | No warranty talk, or gets vague about it |
| Safety | Follows safety regulations on the job site | Cuts corners, works fast and messy |
Final Verdict
Hiring the right decking contractor is not something to rush. Take your time. Ask questions. Check the papers. Get everything in writing.
I know it feels slow when you’re excited to finally get that new deck for your backyard. I felt that way too. But a few extra days of checking references and reading a contract can save you thousands of dollars and a lot of headaches later.
My advice, from someone who learned this the hard way: don’t sign anything on day one. Sleep on it. Ask your questions. A good worker will wait for you, because he knows he does good work and he’s not worried about you finding someone better.
