History
We know what counts and our history backs it up.
Over 100 Years Strong
We certainly have staying power — more than 100 years of it, if you’re counting. We are.
In fact, that’s one of the reasons we’ve grown from Walker Jamar Sr.’s initial $500 investment to a multimillion-dollar company with a rich history.
The Jamar Company was founded in 1913 by Walker Jamar Sr. Since then, we have undergone many changes.
In 1985, APi Group brought us into their fold. Acquisitions since, such as Arrowhead Refrigeration, Bartingale Mechanical, and CMS further enhance our capabilities, expand our reach, and enrich our history of success.
Through it all, we have stayed true to our founder and our history - making every hire, every estimate and every project count.
