About Us

Iberville Companies LLC is one of the largest and fastest growing providers of industrial insulation and related specialty contracting services in the United States. We provide a variety of specialty contracting services to the Power, Refining and Chemical Industries. While our service areas are primarily in the Southern U.S., we have and continue to perform projects throughout much of the rest of the country.

Iberville Companies LLC consists of subsidiaries: Iberville Insulations LLC, and Industrial Asbestos Removal LLC, which both provide specialized contracting services to best meet the various market demands.

  • Iberville Insulations, the original company of the group, was founded in 1981 by Mr. C.M. “Kit” Bonvillian, Sr. and Mr. Herman H. Warthen, Jr. After many years of tremendous service, Mr. Warthen retired from the business at the end of 2011 and Mr. Bonvillian, Sr. became sole owner.  
  • In 1987, Industrial Asbestos Removal (IAR) was formed to provide asbestos and lead abatement to better serve our clienteles’ overall maintenance and project needs.
  • In 2003, Iberville Companies LLC was formed as the parent company of both Iberville Insulations and IAR.

We are proud to be able to service our clienteles’ specialty contracting needs, whether through a capital project from $500 to $50,000,000 in size or through routine maintenance with manpower needs of 2 to 400 workers. With a tremendous focus on Safety, Quality and Performance, we have successfully met and exceeded the expectations of many clients throughout the U.S. for Thirty-Five Years, and we look forward to the opportunity to provide our services to your company!
