Exterior Challenges

- Seasonal: 6-8 month window in most of the US
- More prep work: Pressure washing, scraping, caulking, wood repair
- Safety risks: Ladder work, heights, sun exposure
- Equipment costs: Sprayers ($500-$3,000), ladders, scaffolding
The Ideal Mix
The most profitable painting businesses do both interior and exterior work, shifting focus with the seasons:
Spring/Summer/Fall (March-October):
- 70% exterior, 30% interior
- Book exterior jobs as primary work
- Fill rain days and gaps with interior jobs
Winter (November-February):
- 10% exterior, 90% interior
- Focus on interior repaints, cabinet painting, commercial work
- Use downtime for marketing and planning
Specialty Services That Boost Both
Cabinet Painting ($3,000-$8,000 per kitchen)
This is one of the most profitable painting services. Material costs are low, but the skill and time command premium prices.
Check our cabinet painting calculator for pricing.
Deck Staining ($500-$2,000 per deck)
A natural upsell for exterior painting customers. "While we're here, want us to do the deck too?"

Color Consultation ($100-$250)
Charge for helping customers choose colors. It positions you as an expert and often leads to the painting job.
How to Price for Maximum Profit
Interior Tips
- Charge per room, not per hour — you get faster over time
- Add trim as a line item — don't include it in the room price
- Charge for ceilings separately — they add significant time
- Accent walls = premium pricing — dark or bold colors need more coats
Exterior Tips
- Always charge for prep separately — pressure washing, scraping, caulking
- Bid the whole house, not per side — larger number feels like better value
- Include a warranty — 2-3 year warranty justifies premium pricing
- Offer body + trim + accent pricing — three colors minimum
