Business Philosophy

Black & McDonald's philosophy of conducting business is based upon the core values of our founder, William John McDonald, who established this company in 1921.

In August, 1991, in his 104th year, he reiterated these beliefs. They have stood the test of time...

  • Do the job right - regardless
  • Talk to the customers regularly, confirm their satisfaction
  • Make the price fair and reasonable
  • A deal is a good one only when it is good for both parties
  • Live up to your promises
  • Treat employees with respect
  • Complete jobs promptly
  • Invoice promptly, fairly, and in detail

We honor and respect these beliefs.


Black & McDonald's depth of experience has made us the partner of choice across a wide range of industries. To get there took time and effort. Our management team invested in the development of our people, determined to make our highly-experienced tradespeople renowned as the best in their industries.
With over 90 years of documented lessons learned, we are able to consistently apply that knowledge - meeting our customers’ most demanding challenges, in their most critical environments.
