Estimating Tips

Always include a contingency of 10-15% for unexpected costs. Break the project into phases to catch missed items. Track actual costs on past jobs to improve future estimates.

Cost Benchmarks

  • Remodel:$100-$250 per sq ft (mid-range)
  • Roofing:$5-$12 per sq ft installed
  • Deck:$15-$35 per sq ft (wood/composite)
  • Painting:$2-$6 per sq ft (interior)

Track estimates vs actuals

Kumevo tracks actual labor hours per project phase so you can compare estimates to reality and improve bidding accuracy over time.

How to Create a Construction Estimate

A construction estimate breaks down a project into its component costs: labor, materials, equipment, permits, and overhead. Accurate estimating is the foundation of a profitable contracting business.

Steps to Estimate

  • Walk the job site and take detailed measurements
  • Break the project into phases (demo, rough-in, finish, etc.)
  • Estimate labor hours per phase based on crew size and productivity
  • Get material quotes from suppliers
  • Add permits, equipment rental, and subcontractor costs
  • Apply contingency (10-15%) and your profit margin
