Andrew Lisa at Markets Today reports people generally don’t associate Blue-Collar jobs with seven-figure bank accounts. Some millionaires, however, trace their fortunes to their time working as Plumbers, Farmers, Construction Workers, Bus Drivers and Janitors.

Here’s a look at the millionaires who built their fortunes on the foundation of the high-paying manual labor jobs that got them started:

General Contractor: Construction work has been the backbone of America’s Blue-Collar culture and many successful people got their start by turning raw materials into structures - among them is Josh Downing. Downing was a 31-year-old full-time General Contractor when he started his journey toward wealth and independence.

How Construction Made Him a Millionaire: While Downing was working for a Construction Firm, he advertised his services on Thumbtack, an on-line platform that pairs Tradespeople with customers. After landing a few side gigs, his Thumbtack profile soon became a lucrative second revenue stream. Those side gigs eventually earned him enough money and connections to form the Construction Firm Direct Movement Group, which brought in $4.9 million in revenue in 2016.

Roofer: Roofing is difficult, dangerous and potentially lucrative work. Lee Haight grew up in the business. His Father and Uncle owned roofing companies and Haight landed his first roofing contract when he was just 13. He took the Roofing Trade to new heights as he combined his skills with an entrepreneurial spirit.

How Roofing Turned Into a Million-Dollar Business: Haight is now a millionaire and runs Roofing Professionals with his Father. It’s a multi-State business that separates itself from the crowd by handling complicated insurance claims processing while also performing residential and commercial restorations. In growing the business, Haight displayed a level of on-line marketing skills and Social Media savvy that is rare among Roofers. His average transaction value is more than $20,000.

Plumber: When Charlie Mullins was a child, he was inspired by a visit from a local Plumber who was popular around town and had plenty of money to spend. At 15, Mullins dropped out of school and became a Plumbing Apprentice. In 1979, the British Entrepreneur started his business, Pimlico Plumbers.

How Plumbing Brought In Millions: Today, Pimlico Plumbers is the biggest plumbing business in London with more than 400 Employees and Mullins might be the wealthiest Plumber in the world. He attributes his success to hands-on management and basic fundamentals. He rode to success on the little things: Showing up on time, making pricing transparent and honest, and cleaning up after himself when the job was done.
