Startup costs are typically around $8,000 to $30,000, depending on your tools, vehicle and how you set up your crew. These are estimates only. Custom-ordered windows can't easily be returned, so take deposits and double-check measurements.

Monthly revenue is typically around $8,000 to $40,000, depending on how many jobs you complete and the size of your crew. These are estimates of revenue, not profit. Warranty claims and callbacks can cost time and money, so plan for them.

Contractor licensing varies by state, county and city, so check with your state licensing board before quoting jobs. Also check local permit and building code rules, insurance and possible bond needs, and EPA Lead-Safe (RRP) certification for homes built before 1978.
