2020 Numbers were down slightly due to Covid.

Increase in net income and profit margins in 2018 is because:

  • The company started performing more niche type of work offering many services in house


  • There was also some imbalance with the billing of some services (which can happen when you switch focus)


  • As the business does more niche work (mechanical) in 2020 and beyond, you can expect to see profit margins and net income increase because profit margins from mechanical work is 35% compared to only 15% from light contracting services
