About Us

It began with the pledge.

"...To place service before profit, the honor and standing of the profession before personal advantage, and the public welfare above all other considerations."

Criterium Engineers was established in 1957 to provide engineering reports on the condition of homes. It was one of the first companies to offer such a service in the United States and has been a primary participant in the development of what is now a thriving national home inspection industry.

Criterium-McWilliam Engineers is a family run business that opened their doors in 1994. Through the years it has grown to a staff of 9.
