Stucco Repair Cost Estimator
Estimate the total cost to repair stucco surfaces based on damage area, repair type, coat layers, and regional labor rates.
Formula
Base Cost/sq ft = (Material Rate + Labor Rate) × Finish Multiplier × Regional Index
Total Cost = max( Base Cost/sq ft × Area + Scaffolding + Painting, Minimum Job Charge )
Material Rates ($/sq ft): Patch = $0.80 • Single-Coat = $1.50 • Three-Coat = $3.20
Labor Rates ($/sq ft): Patch = $4.00 • Single-Coat = $6.50 • Three-Coat = $10.00
Finish Multipliers: Smooth = 1.00 • Dash = 1.10 • Decorative = 1.30
Scaffolding ($/sq ft): 1 story = $0 • 2 stories = $1.50 • 3+ stories = $3.00
Painting/Sealing: $1.80/sq ft × Regional Index (if selected)
Minimum Job Charge: $300
Estimate Range: ±15% of calculated total
Assumptions & References
- Material and labor rates are national averages sourced from HomeAdvisor (2023), Angi Cost Guides (2023), and RSMeans Building Construction Cost Data.
- Three-coat stucco system consists of a scratch coat (~3/8"), brown coat (~3/8"), and finish coat (~1/8"), totaling approximately 7/8" thickness per ASTM C926.
- Regional cost indices are based on U.S. Bureau of Labor Statistics regional wage data and local material cost surveys.
- Scaffolding costs assume standard tube-and-clamp rental; complex rooflines or restricted access may increase costs.
- Painting/sealing rate assumes one coat of elastomeric masonry paint or clear sealer.
- Estimates do not include costs for water damage remediation, lath replacement, insulation, or permit fees, which can add $500–$3,000+.
- Actual contractor quotes may vary by 20–30% depending on local market conditions, project complexity, and contractor experience.
- Minimum job charge reflects typical contractor mobilization and overhead costs for small repairs.
