ISI specializes in the installation, receiving, delivery and asset management of commercial furniture, architectural walls, window coverings, and millwork. We are Chicago’s largest installation operation, and have been a proud union shop since 1973.
Combining product knowledge, training, high standards, best practices, teamwork, and technology, we strive every day to demonstrate the kind of quality, productivity, and integrity that earns the trust and loyalty of our valued partners. Our goals are always to accomplish the work according to our partner’s required schedules, scope, and budget—with the least possible disruption to the client’s normal business operations.
Our 155+ skilled craftsmen are masters of the trade with a conviction for hard work. They are supported by our office and warehouse teams, operating from our headquarters which is centrally located in the Chicago metropolitan area.
Our account executives, project managers, and foremen hold critical industry skill sets. Prior to installation, they assist with mock-ups, RFP responses, staging and phasing logistics, and interview preparations with our partners to maximize team success and win rates. This depth of engagement is one key reason that ISI has become Chicago’s standard for dealers’ and manufacturers’ highest-profile projects.
ISI makes extensive use of mobile office/field communication and email-based dispatching. Our integrated suite of custom software applications expedites the flow of project documentation and communications between field, office, and client project teams. By emphasizing the intelligent application of technology, we assure ISI’s ability to respond quickly and accurately to changing project needs.
Complete Installation Solutions for Chicagoland's Commercial Interiors
ISI was established in 1973 by Bud and Shirley Sprenzel. We were Chicago’s only full-service furniture installation company at the time and we served Chicagoland’s pioneer dealers of systems furniture. Today, ISI continues to break new ground and deliver excellence on behalf of manufacturers, dealers, general contractors, interior designers, architects, property and facility managers, and end users.
We receive, deliver, install, store, maintain, and manage products for a wide variety of built environments, including corporate, industrial, professional services, educational, healthcare, sports, transportation, and hospitality. We are known throughout Chicagoland as the premier installers for commercial furniture, architectural walls, window coverings, and custom millwork.
ISI is a second-generation family-owned company with a well-known commitment to client success and dedication to its employees. Whether in the field, the warehouse or the office, our team demonstrates a strong work ethic, a can-do attitude, and an amazing ability to anticipate, solve, and work around problems.
Logistics Support for High Efficiency and Responsive Service
On any given day, approximately 150 full-time union carpenters are deployed from ISI to projects around Chicagoland. Our field carpenters are seasoned in architectural walls and average 20 years of experience in furniture installations. Over 75% of our carpenters are qualified as project foremen. All ISI installers are OSHA 30-certified and manufacturer-trained and certified in a wide variety of brands and lines.
To support our field crews, ISI’s office team includes sales professionals, project managers, project coordinators, receiving specialists, dispatchers, and accounting and administrative support specialists. Key to keeping product moving, our warehouse is fully staffed with a dedicated manager, asset management specialists, warehouse staff and drivers.
ISI offers 200,000 SF of secure, insured, racked and open warehousing space centrally located to best serve Greater Chicago. Clients can rest assured that their product is protected with our fire and smoke detection, fire suppression, back-up generator, and video security safeguards. Our branded fleet includes one tractor-trailer, seven 24-foot straight trucks, and two 16-foot vans. All vehicles are equipped with GPS and side- and rear-mounted video cams.
ISI invests steadily in information and communication technologies that control costs, tighten response times, and boost productivity for both team members and partners. Our custom project management system was built for desktop and mobile use and dovetails with the ISI app platform to facilitate real-time voice, data, and visual communications between field, office and client teams. We use SnapTracker™ to manage client assets and PlanGrid to collaborate with general contractors and additional project partners during installation and punchlist phases.
