About Installation & Service Company, Inc.
Installation & Service Company, Inc. (ISCO) is a family-owned business proudly serving Wyoming since 1981.

Our Story & Commitment
Installation & Service Company, Inc. (ISCO) is a proud Wyoming-based family business with deep roots in the Mills community. Founded in 1981 by Dan and Judy Spurgin, the company started with just a backhoe, a vacuum truck, and a dump truck, working from their living room and a small rented shop. From the very beginning, ISCO focused on providing essential water and sewer line services alongside septic pumping and installation.
Over the years, ISCO has steadily expanded its offerings to include grease trap and sump system services, asphalt paving, excavation, and even live water main tapping—a unique service ISCO remains the only private company in Wyoming licensed to perform.
By 1985, ISCO had grown into a full-service asphalt paving provider, capable of handling everything from small patches to large-scale road construction. In the late '80s and '90s, the company added dirt work, snow removal, water line thawing, and equipment hauling to its list of services.
Today, Installation & Service Company operates out of a custom-built 7,500 square foot headquarters in Mills, WY, designed to support its growing team and fleet of equipment. With over 15 full-time employees and decades of hands-on experience, ISCO proudly serves customers across Wyoming with unmatched customer service, technical expertise, and a dedication to quality.
At ISCO, we believe in building long-term relationships with our clients by delivering reliable service and trusted solutions for every job, large or small.
