Deck Board Replacement Cost Calculator Use

Whether your deck is showing signs of rot, splintering, or simply looking dated, using a deck board replacement cost calculator is the first step in planning your renovation. This tool helps you estimate the total investment required to swap old boards for new pressure-treated wood, composite, or exotic hardwoods.

Deck Area (Square Feet)
The total surface area of the deck boards you intend to replace. Calculate this by multiplying the length by the width of the deck surface.
Material Cost per Sq Ft
The price of the new decking material. Pressure-treated wood is usually $2-$5, while high-end composite can range from $8-$15 per square foot.
Labor Cost per Sq Ft
The amount a professional contractor charges to install the new boards, typically ranging from $8 to $20 depending on your location.

How It Works

The deck board replacement cost calculator uses a linear formula to combine various project expenses. It assumes you are keeping the existing structural joists and only replacing the top "skin" of the deck.

Total Cost = [Area × (Materials + Labor + Removal)] + Fixed Fees

  • Removal Costs: Often overlooked, this covers the labor to unscrew or pry up old boards and haul them away.
  • Contingency: We recommend adding 10% to account for board waste, angled cuts, and unforeseen repairs to joists.
  • Fasteners: Includes the price of deck screws, hidden fasteners, or structural bolts.

Calculation Example

Example: Replacing a 200 sq ft deck with mid-range composite boards.

Step-by-step solution:

  1. Area = 200 sq ft
  2. Material Cost (Composite) = $9.00/sq ft
  3. Labor Cost = $12.00/sq ft
  4. Removal Cost = $3.00/sq ft
  5. Base Calculation: 200 × ($9 + $12 + $3) = $4,800
  6. Add $200 for fasteners/disposal: $5,000
  7. Total Result = $5,000

Common Questions

Is it cheaper to replace deck boards or the whole deck?

Replacing only the boards (resurfacing) is significantly cheaper, often saving 50-70% compared to a full rebuild. However, this is only possible if the underlying frame and joists are structurally sound and free of rot.

How much does it cost to remove old deck boards?

Professional removal and disposal typically cost between $2 and $5 per square foot. If you do this yourself, you only pay for the dumpster rental or landfill fees.

Which material lasts the longest for replacement?

Capped composite and PVC decking last the longest, often featuring 25-to-50-year warranties. While the upfront cost in the deck board replacement cost calculator will be higher, the long-term maintenance savings are substantial.
