I'd like to clarify a few points in the article. BELFOR, Statewide and Jarvis are all headquartered in Michigan with multiple offices throughout the state, making them "local" contractors.
Restoration contractors are trained and equipped to handle major catastrophes. They bear most of the costs up front before they are paid a dime, which can take several months to several years to collect from an insurance company. In the meantime, the insured is back in their home or business because of the work done to restore their structure and contents.
Companies do pull in resources from other areas when a large catastrophe hits because local resources can often be taxed beyond their limit. Wildfires, hurricanes and tornadoes can wipe out the resources in a local area.
