Start with the calculator

Use the calculator first so the DIY and contractor comparison starts from the same project size and assumptions.

When DIY can make sense

  • A small, single-story home or detached structure with stable, sound surfaces
  • Straightforward access from the ground with a realistic weather window
  • You can complete washing, scraping, caulking, masking, and cleanup carefully

When a contractor can make sense

  • Two- or three-story access, steep terrain, scaffolding, or lift needs
  • Extensive peeling, rot, water damage, lead-safe work, or siding repair
  • A full-house deadline, complex trim package, or warranty-backed finish matters

How to decide

  • DIY savings are most realistic when the surface is sound and access is simple; prep time is usually the make-or-break part of the job.
  • Get contractor bids before buying materials when upper-story work, major scraping, repairs, or safety equipment are involved.
  • Compare every option with the same paint product, coat count, primer decision, prep standard, and repair allowance so the lower quote is meaningful.

2,328 sq ft
2,588 sq ft gross less 260 sq ft openings

Starter shopping list

  • Rollers, brushes, trays, drop cloths and cleanup supplies 1 project kit allowance

This example is generated from the same calculator logic used on the Exterior house paint calculator page.

Cost factors to compare

  • Net exterior paintable area, gables, openings, and the number of coats
  • Paint grade, primer, caulk, patching, masking, and other prep materials
  • Story height, access equipment, surface condition, and labor time
  • Repair work, specialty coatings, color changes, and weather interruptions

Contractor quote checklist

  • Paint brand, product line, sheen, color, primer, and coat count listed
  • Washing, scraping, sanding, caulking, masking, and spot priming clearly scoped
  • Access equipment, protection of landscaping, and daily cleanup included or excluded
  • Siding, trim, flashing, rot, and substrate repairs priced separately where possible
  • Warranty, weather policy, and final walkthrough process written into the quote

Common mistakes

  • Estimating from floor area instead of exterior wall and gable area
  • Treating paint as a fix for failing siding, rot, moisture, or loose caulk
  • Comparing bids with different prep levels, coats, paint grades, or access assumptions
