Riddleberger Brothers, Inc., founded in 1940 by Ike Riddleberger, Sr. and Roy Riddleberger, started as a small plumbing company located in Harrisonburg, Virginia.  Through the years the company has seen many changes in the business and industry.  Technology has continually advanced in mechanical contracting, and with these advances Riddleberger Brothers has adapted and evolved to stay current.

One thing that has remained constant at Riddleberger Brothers has been a commitment to providing quality work and excellent craftsmanship.  The company leaders throughout our history have always instilled this dedication to quality, and our employees make that happen.  Our seventy-five plus years in business is in large part due to the many dedicated employees who have worked here over the years.  Many of the “old timers” laid the foundation for quality work and excellent craftmanship and passed it along to others.

This foundation is what makes Riddleberger Brothers the premier full-service plumbing, mechanical, service, controls and design-build company it is today.
