What Drives the Cost
Scope of Damage
$200 - $5,000Replacing a few cracked boards costs $200-$500. Replacing 25-50% of the decking surface runs $800-$2,500. Structural repairs (joists, beams, ledger board) can range from $1,500-$5,000 depending on the extent of damage.
Decking Material
$3 - $15/sq ftPressure-treated lumber replacement boards cost $3-$6/sq ft. Cedar or redwood runs $6-$10/sq ft. Composite decking for replacement boards costs $8-$15/sq ft. Material choice significantly impacts the total for large-area repairs.
Structural vs. Cosmetic
$0 - $3,000Surface-level repairs (boards, railings, staining) are straightforward. Structural repairs involving joists, beams, posts, or the ledger board are more complex and add $1,000-$3,000 due to the need to temporarily support the deck during repairs.
Railing Replacement
$200 - $2,000Repairing a few balusters costs $200-$400. Replacing an entire railing system runs $20-$60/linear ft. A full railing replacement on a 200 sq ft deck typically costs $800-$2,000 depending on material (wood vs. composite vs. cable/metal).
Permits & Code Compliance
$0 - $500Minor repairs usually don't need permits. Structural repairs or railing replacements may require permits ($75-$200) and must meet current building codes, which could require additional updates to bring the deck up to code.
Cost by Material or Type
| Option | Cost |
|---|---|
| Pressure-Treated LumberBudget repairs, matching existing pressure-treated decks | $3-$6/sq ft |
| Cedar/RedwoodHigher-end wood decks, natural appearance preference | $6-$10/sq ft |
| Composite (Trex, TimberTech)Low-maintenance priority, upgrading from wood, long-term value | $8-$15/sq ft |
| PVC DeckingPool decks, wet climates, maximum durability | $10-$18/sq ft |
Regional Cost Variations
Labor rates and material costs vary significantly by region. Apply these multipliers to the national average to estimate costs in your area.
| Region | Adjustment | Est. Average |
|---|---|---|
| Northeast | +15% to +25% | $2,300 - $2,500 |
| West Coast | +20% to +35% | $2,400 - $2,700 |
| Southeast | -15% to -10% | $1,700 - $1,800 |
| Midwest | -15% to -5% | $1,700 - $1,900 |
| Mountain West | +5% to +10% | $2,100 - $2,200 |
Timeline & What to Expect
DIY vs. Professional
Good for DIY
- Replacing individual deck boards
- Tightening loose screws and hardware
- Replacing individual balusters
- Staining and sealing the deck
- Power washing
Potential savings: 40-60%
Hire a Pro
- Joist and beam replacement
- Ledger board repair or replacement
- Post replacement requiring footing work
- Code compliance assessment
- Structural reinforcement
DIY feasibility: Partial
Risk warning: Surface-level repairs are very DIY-friendly. However, structural repairs are critical safety work - a deck collapse can cause serious injury. If you suspect joist, beam, post, or ledger board damage, have a professional assess the situation. Ledger board failure is the number one cause of deck collapses.
How to Save Money
Replace only damaged boards rather than the entire surface - spot repairs at $3-$15/board vs. $1,500-$5,000 for full resurfacing
Do your own staining and sealing to save $500-$1,200 on a typical 200-300 sq ft deck
Use pressure-treated lumber for structural repairs (joists, beams) even on composite decks - it's hidden and saves $500+
Bundle repairs with annual staining/sealing to avoid paying a separate mobilization fee of $100-$200
Address small problems early - a $50 board replacement now prevents a $2,000 joist repair later
Compare quotes from general contractors and specialized deck builders - deck specialists are often 15-20% less for deck-specific work
If replacing railings, consider cable railing kits ($15-$25/linear ft installed) as a modern alternative to full wood replacement at $30-$60/linear ft
Questions to Ask Your Contractor
“Is the damage cosmetic or structural, and how can you tell?”
Why this matters: Surface rot doesn't always mean the structure is compromised, but it can hide deeper problems. A thorough inspection with a moisture meter or probing tool reveals the true extent of damage.
“Is the ledger board connection to the house still sound?”
Why this matters: The ledger board is the single most critical structural element. It connects the deck to the house and is the number one failure point in deck collapses. This must be inspected even for cosmetic repairs.
“Will any repairs trigger a requirement to bring the entire deck up to current code?”
Why this matters: In some jurisdictions, repairs exceeding a certain percentage of the deck's value require the whole structure to meet current code. This can add significant cost for older decks.
“Can you match the existing decking material and color?”
Why this matters: Mismatched boards look bad and may weather differently. If an exact match isn't available, the contractor should suggest alternatives like replacing an entire section for a cleaner look.
“What's causing the damage, and how do we prevent it from recurring?”
Why this matters: Fixing the symptom without addressing the cause (poor drainage, ground contact, missing flashing) means you'll be paying for repairs again in a few years.
