How to Price a Painting Job (Interior and Exterior)
Painting is one of the most quoted trades in residential construction. Homeowners know they can get multiple bids easily, which means your pricing needs to be both competitive and profitable.
Here is the system for estimating painting jobs.
Step 1: Measure Paintable Surfaces
Painting is priced by square footage, not by room. You need to measure:
Interior:
- Wall square footage (height x perimeter, minus windows and doors)
- Ceiling square footage
- Trim linear feet (baseboards, crown, casing, chair rail)
- Door count and type (flat, paneled, French)
- Cabinet faces if included
- Closet interiors if included
Exterior:
- Siding square footage by type (lap, board and batten, stucco, brick)
- Trim and fascia linear feet
- Window and door trim count
- Soffit square footage
- Deck or porch surfaces if included
- Shutters count
Contractors in San Francisco and Vancouver deal with multi-story Victorian homes that require extensive scaffolding and ladder work. Factor access into your measurements.
Step 2: Assess Prep Requirements
Prep is where painting estimates go wrong. The paint itself is fast. The prep is what takes time.
Interior prep:
- Patching holes and cracks
- Sanding rough surfaces
- Caulking gaps around trim
- Priming bare wood, stains, or dark colors
- Masking and protecting floors and fixtures
Exterior prep:
- Power washing
- Scraping loose paint
- Sanding and feathering edges
- Caulking gaps and cracks
- Priming bare wood and repaired areas
- Lead paint testing and abatement (pre-1978 homes)
A house that needs heavy scraping and repair will take 2 to 3 times longer to prep than a house in good condition. Never quote exterior painting without seeing the prep situation firsthand.
Step 3: Calculate Material Costs
Paint coverage is roughly 350 to 400 sq ft per gallon on smooth surfaces, less on textured or porous surfaces.
- Builder grade paint: $25 to $40 per gallon
- Mid-range (Benjamin Moore Regal, SW Duration): $50 to $70 per gallon
- Premium (BM Aura, SW Emerald): $70 to $90 per gallon
- Exterior paint: $40 to $80 per gallon
- Primer: $25 to $50 per gallon
- Stain (deck/fence): $30 to $60 per gallon
Add supplies: rollers, brushes, tape, plastic, caulk, patching compound, sandpaper. Budget $50 to $150 per job in consumables for interior, more for exterior.
Step 4: Price Labor
Painting labor rates per square foot:
Interior:
- Walls (2 coats): $0.75 to $1.50 per sq ft
- Ceilings: $1.00 to $2.00 per sq ft
- Trim (per linear foot): $1.00 to $2.50
- Doors (per door): $50 to $100 each
- Cabinets (per linear foot of face): $30 to $60
Exterior:
- Siding (2 coats): $1.00 to $2.50 per sq ft
- Trim and fascia: $1.50 to $3.00 per linear foot
- Prep-heavy surfaces: Add 30% to 50% for scraping and repair
These are labor only rates. Material, overhead, and profit are on top.
Step 5: Factor Access and Complexity
- High ceilings (12+ ft): Add 20% to 30% for ladder and scaffold time
- Two and three story exteriors: Scaffold rental ($150 to $500+) or lift rental
- Detailed trim work: Crown molding, wainscoting, chair rail adds precision time
- Multiple colors: Each additional color adds taping and setup time
- Occupied homes: Working around furniture and daily life slows production
Step 6: Apply Markup
Drywall and painting contractors should target 30% to 45% markup covering:
- Vehicle and fuel
- Insurance
- Drop cloths, ladders, and equipment wear
- Marketing and lead costs
- Warranty touch-ups
- Profit
Step 7: Present the Estimate
Detail matters in painting estimates. Show:
- Which rooms or areas are included
- Number of coats
- Paint brand and product
- What prep is included
- What is excluded (furniture moving, wallpaper removal, drywall repair beyond patching)

Why Painting Contractors Cannot Afford Spreadsheet Estimates in 2026
Painting is the highest-volume quoting trade in residential construction. You might quote 30+ jobs per month. Every hour spent on spreadsheet estimates is an hour you are not painting and not getting paid.
Here is the 2026 reality:
- Paint prices are up 25% to 35% since 2023. If your spreadsheet template still has 2024 pricing, you are underbidding every job. Benjamin Moore and Sherwin-Williams have both raised prices multiple times. Your estimates need current numbers every single time
- Lead paint disclosure is getting stricter. The EPA is cracking down on RRP (Renovation, Repair, and Painting) compliance in 2026. If you are painting pre-1978 homes, your estimate needs to include testing, containment, and disposal costs. Spreadsheets do not remind you of this
- Multi-room estimates are tedious. A whole-house interior painting job with 12 rooms, 3 colors, varying prep levels, and different ceiling heights takes 2 to 3 hours to estimate on a spreadsheet. That is insane for a $4,000 to $8,000 job
- Homeowners compare format, not just price. When a homeowner gets 5 painting quotes, the one with room-by-room breakdowns, paint specs, and professional branding wins even if it is not the cheapest
EZ-Estimates lets painters walk through the house, describe each room by voice, and generate a complete estimate with paint quantities, prep hours, labor per room, materials, and markup in minutes. Send it from the driveway while the homeowner is still excited about their color choices.
Speed + professionalism = more painting jobs at better margins. That is the formula in 2026.
The Bottom Line
Painting pricing is square footage times prep times coats. Contractors who measure accurately, assess prep honestly, and present professionally win the most work at the best margins.
