Deck work in the Charlotte metro is a $15,000-$45,000 decision for most homeowners doing a full rebuild, and $450 to $9,000 for repair and refinish scopes. The quality spread between good and bad deck contractors is wider here than people expect - we have rebuilt plenty of decks that were less than 5 years old because the original contractor skipped flashing, used nails instead of structural screws, or cut corners on footings. Whether you need a full build or a targeted deck repair, here is how to vet a contractor before you sign.
The 8-Question Vetting Call
Before scheduling an inspection, ask these over the phone. If any answer is a hedge, move on.
- Are you insured for general liability and workers compensation, and can you email the certificates?
- Do you pull the permit yourself or do I pull it?
- Do you employ your own crew or use subcontractors?
- How long have you been building decks in the Charlotte metro?
- Do you have 3 to 5 recent local references I can call?
- What is your written workmanship warranty?
- What is your payment schedule?
- Can you send me a sample quote showing the line-item detail I will get?
Good contractors answer all eight in one call. Evasive contractors try to skip ahead to a sales visit at your home before you have confirmed basic credentials. Do not skip this call.
Insurance and License Checks
Documents to collect before signing:
- General liability COI. $1M per occurrence minimum, named certificate holder should be the insurance company, not the contractor.
- Workers compensation COI. Required in NC for companies with 3+ employees.
- NC Contractor License (if applicable). Look it up at the NC Licensing Board for General Contractors website - anyone can claim a number, only the database verifies it.
- BBB and Google profile. Check for a real-address business (not a PO box), a consistent local phone number, and reviews spanning at least 12 months.
NC only requires a GC license for projects over $40,000. Most deck projects in our area come in under that threshold, so license is optional. Insurance is non-optional. Never hire an uninsured contractor, regardless of price.
What a Good Quote Looks Like
A professional deck quote has these line items:
- Total square footage of deck surface and total linear feet of railing
- Per-sqft and per-LF rates clearly stated
- Decking material brand, line, and specific color code
- Railing style, material, and post spacing
- Substructure scope - new footings vs reuse, ledger re-flash, joist sister count, post count
- Stair count and tread material
- Permit fee (either included or itemized)
- Debris haul-away scope
- Payment schedule with specific milestones
- Written workmanship warranty terms
- Project start and projected completion dates
If the quote is a single-line number with no breakdown, ask for a detailed version. "Custom deck - $14,500" is not enough to compare against another bid, and it is not enough to hold the contractor accountable if something changes mid-build.
Warranty Language That Matters
The words that make a warranty real vs decorative:
- Transferable (or not) - if you sell the house in 5 years, does the next owner get coverage?
- Covered defects - good warranties specify workmanship (installation quality), not just "material failure."
- Exclusions - abuse, acts of God, deferred maintenance. These are standard, but read them.
- Remedy - repair at contractor's expense, or pro-rated refund, or something else?
- Duration - industry standard is 1 to 2 years on labor. Our standard is ' . (int) WARRANTY_YEARS . ' years. Manufacturer warranty on materials is separate (Trex = 25 years fade and stain).
Red Flags We See in the Charlotte Market
Real patterns from homeowners we have helped after bad experiences with other contractors:
- Full payment up front. A contractor who wants 100% before starting is funding the previous client's job, not yours. A deposit that covers materials on a large job is normal; the whole price is not.
- Nails instead of structural screws. Never use plain nails on decking. Corrosion-resistant structural screws only.
- Ledger without flashing. The single most common cause of rot on a 10-year-old Charlotte deck - whether it is a pressure-treated or composite build.
- Concrete footings poured without depth measurement. NC residential code requires footings below the frost line - typically 12 to 18 inches in our area. "Just a few inches" will heave in 5 years.
- "No permit needed" on a scope that requires one. If you get caught, you pay the fine and redo the work.
- Verbal-only quote. Get everything in writing before any material is ordered.
- "Cash only, no invoice." No paper trail = no warranty enforcement.
Payment Structure
Our standard terms:
- Small repairs and jobs under $10,000: paid on completion, after you walk the deck and sign off. No deposit.
- Refinishing and jobs of $10,000 or more: 50% at signing (covers materials), 30% when materials are delivered, 20% at substantial completion.
We accept all major credit cards, Zelle, Venmo, and cash. That matches our sister glass company and keeps invoicing simple. Any contractor asking for 100% before the job is done is a hard no.
Tip
If a contractor cannot tell you in plain English what ledger flashing is, what structural screws are, or what NC's 4-inch sphere rule is, move on. Those three questions separate deck-experienced crews from general-handyman-labor crews.
