What Installation Specialists does

Installation Specialists, Inc. (ISI) is a family-owned commercial interiors installation company founded in 1973 in Chicago and headquartered in Itasca, Illinois. The company provides installation, receiving, delivery, asset management, and project management services for commercial furniture, architectural walls, window coverings, and millwork, serving as the last-mile execution arm for major OEMs, contract furniture dealers, general contractors, interior designers, architects, and end users across corporate, public sector, education, healthcare, and hospitality verticals. ISI reports operating in 90% of Chicago Loop buildings and is self-described as Chicago's largest commercial furniture installation company and the second largest of its kind in the United States.

The business is built around a skilled labor pool of 200+ full-time union carpenters averaging 20 years of experience, backed by 200,000 square feet of secure, climate-controlled warehousing, 17 receiving docks, and a fleet of trucks and vans. ISI's technology stack centers on OrderWorks, a proprietary operating system and CRM that manages the full quote-to-invoice workflow, augmented by PlanGrid for construction documentation, SnapTracker for furniture asset management, and a custom mobile app for real-time field communication. The company also offers custom woodworking (20+ master carpenters), window coverings, facility decommissioning, product care (refinishing, reupholstery, repair), and an online self-serve delivery scheduling portal.

Revenue is generated through project-based professional services contracts billed on scope, complexity, and labor, with no public pricing disclosure. Customer acquisition is relationship-led through long-standing manufacturer and dealer partnerships (Allsteel, Haworth, Kimball, MillerKnoll, Steelcase, Teknion, and others), supplemented by a website Request-an-Estimate channel and FSN peer network relationships. The company has worked with dealers in 28 states, indicating national channel reach even though physical installation is concentrated in Chicagoland. Family ownership remains in place under CEO John Sprenzel, son of founders Bud and Shirley Sprenzel.
