How to Estimate Plaster Repair
Contractor method for estimating plaster repair by area, condition, preparation and finish.
Plaster repair is priced by the area and the condition. Cracks and failing patches raise the factor, and preparation adds a fixed line.
THE SHORT ANSWER
How do you estimate plaster repair?
Multiply area by the rate and coats and a condition factor, then add prep. 200 sq ft at $3.50 over 2 coats with a moderate factor and prep totals about $2,080.
Measure the area
Total the plaster area to repair. Larger areas and higher condition scale the work.
- Area
- Condition
- Prep
- Coats
Apply a condition factor
Minor cracks are the baseline; moderate and major damage multiply the rate because they need more buildup.
Add prep and coats
Preparation for cleaning, primer and masking is a fixed line, and multiple coats add to the work.
Total and validate
200 sq ft at $3.50 over 2 coats at a 1.4 factor is the main cost, plus prep. Use the Plaster Repair Cost Calculator.
