Walsh Insulation was founded by Tom Walsh Sr. in March of 1988 in Jefferson City, MO after 25 years of field experience. We primarily serve the mid-Missouri area extending into Hannibal, Rolla, Kirksville and some areas of Illinois.  As we continue to grow, we are actively pursuing work in all markets. We pride our company on installing quality insulation for various commercial and industrial projects of all sizes.

Tom and Chris Walsh bought the company in November of 2002 when Tom Sr. retired.  Since then our operations have expanded into new markets and we are always striving to exceed our customer’s expectations while effectively handling all manners of unforeseen circumstances.  While providing a quality, industry standard product is our passion, safety is always job #1.

Our promise as a contractor is to build community value into every project while delivering professional expertise, exceptional customer service and quality insulation.
