How to Read a Contractor Estimate (And Spot Hidden Fees)

A contractor estimate can be confusing. Here is what every line means and where fees hide.


Understanding Your Contractor Estimate


A well-written contractor estimate tells you exactly what you are paying for. A poorly written one hides costs. Here is how to read between the lines.


What Should Be Included


Every legitimate estimate should have:


  • Scope of work: Detailed description of exactly what will be done
  • Materials list: Specific products, brands, quantities with individual prices
  • Labor costs: Hours estimated and hourly rate, or fixed labor cost
  • Permits: Cost of any required permits
  • Timeline: Start date, milestones, completion date
  • Payment schedule: When payments are due and how much
  • Warranty: What is covered and for how long

    • Common Hidden Fees


    Watch for these charges that contractors sometimes sneak in:


  • Change order fees - Legitimate but should be capped at a percentage
  • Travel/mobilization charges - Fair for distant jobs, not for local contractors
  • Waste removal - Should be included, not an add-on
  • Final cleaning - Should be included in any major project
  • Permit fees - Sometimes listed separately at inflated prices

    • What Fair Markups Look Like


  • Materials markup: 10-25% is standard
  • Subcontractor markup: 10-20% is standard
  • Overhead and profit: 15-25% of total is standard
  • Total markup over raw cost: 35-70% is typical for a profitable, legitimate contractor

    • Red Flags


  • No breakdown (just a total number)
  • "Allowances" for major items (this means the price will go up)
  • Missing permit costs
  • No timeline or completion date
  • Payment terms heavily front-loaded
