What Does It Cost to Start a Plumbing Business?
Starting a plumbing business requires a relatively modest investment compared to retail or food service businesses, with most solo operators launching for $15,000 to $50,000. The largest expenses are a well-equipped service vehicle and the licensing process, which varies significantly by state. Plumbing remains one of the most recession-resistant trades because people always need working water and drainage.
Licensing Requirements for Plumbing Businesses
The licensing path is the biggest barrier to entry for new plumbing business owners. Most states require 4-5 years of apprenticeship under a licensed plumber before you can sit for the journeyman exam, and another 1-3 years before qualifying for a master plumber license. Some states also require a separate contractor license to operate a business, which involves proof of insurance, a surety bond ($5,000-$25,000), and a business management exam.
