Interstate Restoration Group was a national leader in disaster recovery and property restoration services for commercial enterprises, founded in 1998. The company specialized in helping businesses recover from events like fires, floods, hurricanes, and other catastrophic incidents. In 2016, Interstate Restoration was acquired by FirstService Corporation and subsequently merged with FirstOnSite Restoration (FirstService's Canadian restoration arm) to form FIRST ONSITE Property Restoration. Today, as part of FIRST ONSITE, the legacy and expertise of Interstate Restoration Group continue to serve clients across North America, offering a comprehensive suite of emergency response, remediation, and reconstruction services.
Serves as the central command for U.S. operations, coordinating large-scale disaster response, client relations, strategic planning, and administrative functions for FIRST ONSITE.
Modern office facility equipped with advanced technology to support nationwide emergency response coordination and project management. Designed to foster collaboration and efficient operations.
A dynamic, fast-paced environment focused on rapid response and client service. Emphasis on teamwork, resilience, and supporting communities and businesses in crisis. The culture values preparedness and expertise.
The U.S. headquarters is pivotal for managing complex restoration projects across the nation, ensuring consistent service quality, and deploying resources effectively during major disaster events.
FIRST ONSITE, incorporating the legacy of Interstate Restoration Group, operates primarily across North America, with extensive coverage throughout the United States and Canada.
