How much does exterior house painting cost?

Estimate exterior house painting materials, prep, labor, primer, access, and directional contractor cost from paintable area and project conditions.

Reviewed - July 16, 2026

Short answer

Exterior painting cost starts with net paintable wall and gable area, then changes with paint grade, coat count, primer, prep, story height, and access. Materials and labor should be compared separately because two bids with the same house size can cover very different preparation or repair scope.

The exterior paint calculator estimates finish paint, primer, prep materials, directional labor, and contractor total using the current selected region. Its story and surface-condition settings make the cost range more useful than a single price per square foot.

Use the result to build a comparable quote scope. Repairs, extensive scraping, lead-safe procedures, lift or scaffold rental, difficult landscaping, and specialty coatings should stay as clear separate line items.

Estimate exterior painting cost

Exterior house painting cost method

  1. Calculate net exterior paintable area from dimensions and openings, or enter a measured net area.
  2. Calculate finish-paint gallons from net area, coat count, waste, and coverage per gallon.
  3. Add primer gallons if the selected surface or paint system needs a primer coat.
  4. Price finish paint, primer, prep materials, and the project supply kit to estimate DIY materials.
  5. Apply the current regional labor range to net paintable area, adjusting for story-height access and selected surface-prep condition, then compare it with the regional contractor small-job minimum.
  6. Add materials and labor to create the directional contractor-total range.
  7. Keep repairs, lead-safe work, scaffolding, lifts, major masking, specialty coatings, and unusual access as separately reviewed scope.

Quick examples

Small one-story repaint
$592–$1,923
24 ft by 20 ft, sound surfaces, one finish coat, no primer
Two-story standard repaint
$3,843–$12,028
40 ft by 28 ft, two gables, weathered surfaces, primer and two coats
Three-story premium exterior
$6,034–$18,839
32 ft by 26 ft, one gable, weathered surfaces, primer and two coats
2,400 sq ft known-area repaint
$3,957–$12,390
Weathered net area, standard paint, primer and two finish coats
1,800 sq ft heavy-prep exterior
$4,092–$12,607
Known net area, premium paint, primer and two finish coats

These generated estimates separate material and labor assumptions. The selected region, story height, surface condition, paint grade, primer, and coat count can all change the range.

Starter shopping list

  • Exterior primer 8.6 gal
  • Caulk, patching compound, sanding and masking supplies weathered prep allowance
  • Rollers, brushes, trays, drop cloths and cleanup supplies 1 project kit allowance

What a comparable quote should include

  • Ask for the paint brand, product line, sheen, color count, coat count, primer, and surfaces included in writing.
  • Match washing, scraping, sanding, caulking, masking, protection, cleanup, and touch-up scope before comparing prices.

Why access and prep move cost

  • Labor often rises on two- and three-story homes because setup, ladder moves, safety controls, and production speed change.
  • Weathered surfaces may need more cleaning, scraping, sanding, caulking, spot priming, and repair than a simple maintenance repaint.

Materials versus labor

  • A lower material price does not prove a lower project cost if it changes coverage, durability, coat count, or warranty expectations.
  • Use the calculator's material and labor cards to identify whether a quote difference is mainly product, prep, access, or labor scope.

Separate repair and risk allowances

  • Request unit prices or a stated allowance for damaged trim, siding, flashing, caulk failure, and other concealed repairs.
  • If older coatings, high access, or questionable substrates are present, get qualified advice before assuming ordinary painting scope applies.

Common mistakes

  • Comparing material-only shopping carts with labor-included contractor proposals.
  • Using a single price per square foot without accounting for stories, access, prep, gables, or paint system.
  • Accepting an unclear quote that does not state paint, primer, coats, preparation, repairs, and cleanup.
  • Treating visible deterioration as paint-only work when the underlying siding, trim, moisture, or flashing needs repair.
  • Assuming a contractor total includes lifts, scaffolding, lead-safe work, specialty coatings, or landscaping protection without confirmation.

FAQ

What affects the cost to paint a house exterior?

The main drivers are net paintable area, paint grade, coats, primer, surface condition, story height, access, prep, repairs, and regional labor. Gables, trim, shutters, porches, and difficult site access can add scope as well.

Is exterior paint labor based on floor area?

No. Labor is more closely tied to exterior surfaces, prep, story height, access, and detail work than to interior floor area. Use measured paintable exterior area for a more useful planning comparison.

Does exterior painting cost include primer?

It should be stated separately. In the calculator, enabling primer adds a one-coat primer material allowance; contractor quotes should specify whether priming is full, spot-only, or excluded.

Why are two exterior painting quotes so different?

Different bids may include different paint systems, coats, prep, repairs, access equipment, protection, cleanup, warranty, or exclusions. Normalize those items before treating price as the deciding difference.

Does the estimate include siding repair?

No. The estimate includes a planning allowance for paint prep materials, not structural or moisture-related repair. Ask for siding, trim, flashing, rot, and substrate repairs as distinct quote lines.

When should I get an exterior painting contractor bid?

Get bids when the work involves upper stories, significant peeling, repairs, lead-safe procedures, safety equipment, tight scheduling, specialty coatings, or any uncertainty about the condition of the exterior.
