Floor Repair Cost Calculator

Estimate subfloor sheet quantities and a planning budget using your local supplier and contractor prices.

✓ Browser-based
01 Project dimensions

Measure only the area needing replacement. A subfloor sheet may be cut or oriented differently depending on framing layout; quantities are a planning allowance.

02 Local project costs

How this calculation works

We multiply length by width to estimate the repair area. We add your selected material waste allowance, divide by the chosen sheet size, and round up to a whole sheet. Material cost equals the resulting sheet count multiplied by your sheet price. Labor is the original repair area multiplied by your labor rate per square foot. We then add your other fixed costs and a contingency percentage.

What can change your actual price?

A floor with hidden moisture damage, compromised framing, pipes or wiring in the work area, difficult access, or an unusual installation method can cost more than this planning model suggests. Sheet layout and the direction of joists may affect how many full sheets are needed. Always check product specifications and local requirements.

What is not included?

Finish flooring, structural framing repairs, moisture remediation, local taxes, permits, and other site-specific requirements are excluded unless you separately account for them in the “other fixed costs” field. This tool does not diagnose a safe or unsafe floor.
