Best for: Southern California homeowners dealing with water damage that led to mold, who want one company to handle extraction, remediation, and reconstruction under a single project manager.
Service area: Headquartered in Carson, California, with a second location listed in Rancho Cucamonga. PRC claims to serve all cities across Los Angeles County, Orange County, San Bernardino County, Riverside County, and Ventura County. Their service area page lists specific cities in each county. That is a very wide footprint for a company with two offices — realistic for the LA-to-Inland Empire corridor, but response times to Ventura County or far Riverside locations like Hemet or Wildomar should be confirmed.
