Coastal Inspection Services

Coastal Inspection Services holds a 5-star rating across 863 Google reviews, which carries real weight for Mission Viejo homeowners. The area's climate - averaging 67% relative humidity and 14 inches of annual rainfall - creates conditions where mold thrives, especially in older homes like the median property built in 1979. That consistent five-star track record suggests the company has earned trust handling the mold concerns that plague many local properties. A standalone mold inspection in this region typically costs $200-$600, so you're investing in expert assessment during a critical decision point for your home.

Before hiring, verify that Coastal Inspection Services holds a valid Contractor's State License Board (CSLB) license and carries appropriate insurance. California doesn't require a specific state license for mold remediation, but any contractor performing work must hold an active CSLB license. Also confirm IICRC certification, which signals technical competency. One important caveat: inspectors who also perform remediation work create a conflict of interest under industry standards, since they may recommend more extensive (and costly) treatment than necessary. Consider getting a separate, independent inspection if the company offers both services.
