JLM Environmental

JLM Environmental is a mold remediation contractor serving Hawthorne with a 4.7-star rating across 121 Google reviews. That track record matters here, given Hawthorne's 73% average relative humidity and 14 inches of annual rainfall - conditions that create real mold risk in older homes. With a median home age of 1971, many Hawthorne residences are particularly vulnerable to moisture problems. When you're dealing with potential mold in your house, knowing that a local contractor has consistently satisfied over 120 homeowners provides solid reassurance.

California doesn't require a specific state license for mold remediation, but any contractor you hire must hold a valid Contractor's State License Board (CSLB) license. Before calling JLM Environmental or any remediation company, verify their CSLB credentials and confirm they carry insurance. You'll also want to check whether they hold IICRC certification, which demonstrates professional training in mold assessment and remediation. Typical remediation projects in Hawthorne run between $1,900 and $5,650, so get a detailed estimate in writing before work begins.
