5 Best Mold Removal Services in Los Angeles (2026)

Mold Inspection Sciences has performed thousands of mold investigations across the greater Los Angeles metro over more than 20 years, offering mold inspection, testing, CIRS protocol assessments, and post-remediation clearance testing. The company explicitly does not perform remediation itself, positioning that separation as the reason clients get an unbiased read on their situation. Reviewers repeatedly describe inspectors who identified where testing was and wasn't needed, rather than upselling every visit.

Like Mold Inspection Sciences, the company performs no remediation itself. Reviewers describe getting an inspector out within hours of calling, including one case where testing was scheduled and completed the same morning.

Mold Testing & Removal Services, led by Henry, offers both mold testing and the follow-up remediation work in the greater Los Angeles area, serving residential and rental properties across the region.

24/7 Mold Inspection Los Angeles, run by Henry, performs both mold inspection and physical remediation, including framing treatment and sealing after a leak-driven mold problem.

Mold Inspection & Testing Los Angeles, known as MI&T, is an independent mold inspection company serving LA, Orange and San Bernardino counties, explicitly built around having no conflict of interest since it performs no remediation. Reviewers repeatedly note its pricing came in well below competing quotes for the same job, and describe inspectors identifying hidden mold sources, including one case tracing a leak to an HVAC unit that a landlord had otherwise ignored.
