How these estimates work
Each guide counts the materials a job needs with the same formulas as our calculators, prices them at typical retail prices, adds a contractor markup on materials, and adds labor at a production rate and an hourly rate. The result is shown as a range, because real quotes vary with region, access, season and the contractor. Change any price or rate to match quotes you've had.
Estimates, not quotes
Use these to budget and to check whether a quote is in the right ballpark. For a real price, get quotes from local contractors who've seen the site.
