National Property Inspections

National Property Inspections carries a 4.8-star rating across 310 Google reviews, a strong track record for Phoenix homeowners. Given that most Phoenix homes were built around 1984 and the region's dry climate (34% relative humidity, 8 inches annual rainfall) creates lower mold risk than many areas, a highly-rated inspector can give you reliable peace of mind. A standalone mold inspection in Phoenix typically costs $200 to $600, so you're comparing options in a straightforward price range.

Before you hire, verify that National Property Inspections holds a valid Arizona Registrar of Contractors (ROC) license if they perform mold remediation work - you can check their license status at azroc.gov. One important note: inspectors who also do remediation work face a built-in conflict of interest under industry standards, since they may recommend more extensive (and costly) remediation than necessary. If you want an unbiased assessment, confirm whether this company inspects only or handles both inspection and remediation.
