How to Use This Calculator
  1. Enter the linear feet or square feet of damaged wood requiring replacement.
  2. Select the wood type: framing lumber, sill plate, fascia, decking, or structural beam.
  3. Input your material cost per linear foot and labor rate per hour.
  4. Review the Total Material Cost, Labor Hours, and Total Repair Cost.
  5. Use the Cost per Square Foot output to benchmark against insurance claim estimates or contractor bids.

How the result changes with Floor joists to repair

Floor joists to repairTotal repair cost ($)
5$1,954.70
18$6,321.92
33$11,361.02
45$15,392.30

What each input means

Sill plate to repair (linear ft)
Linear feet of damaged sill plate (mudsill) to repair or replace.
Floor joists to repair
Number of floor joists needing repair or replacement.
Wall studs to repair
Number of wall studs needing repair or replacement.
Subfloor to replace (ft²)
Square feet of damaged subfloor sheathing (3/4" OSB or plywood).
Method (0=Sister, 1=Partial, 2=Full replace)
0 = Sister/reinforce alongside damaged member. 1 = Partial replacement. 2 = Full member replacement.
Access (1=Easy, 2=Moderate, 3=Difficult)
1 = Open/exposed framing. 2 = Standard crawl space. 3 = Tight/confined area.

What each result means

Total repair cost ($)
Complete cost including materials, labor, shoring, and waste removal.
Lumber material cost ($)
Cost of replacement lumber and sheathing.
Hardware cost ($)
Joist hangers, structural screws, Simpson ties, etc.
Labor cost ($)
Carpenter labor at $75/hour with access difficulty adjustment.
Estimated labor hours
Total carpenter hours including access difficulty.
Temporary shoring cost ($)
Cost for temporary support during load-bearing member replacement.
Waste removal ($)
Disposal of damaged wood and debris.
Avg cost per member ($)
Average repair cost per structural member.

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    4 parameters
    Sill plate to repair (linear ft) = 0, Floor joists to repair = 2, Wall studs to repair = 0, Subfloor to replace (ft²) = 0 = 6 input(s) provided
  2. Calculate Total repair cost
    Total repair cost = totalMaterial + hardwareCost + totalLaborCost + shoringCost + wasteRemovalCost
    946.88 = $946.88
  3. Calculate Lumber material cost
    Lumber material cost = sillMaterial + joistMaterial + studMaterial + subfloorMaterial
    83.3 = $83.3
  4. Calculate Hardware cost
    24 = $24
