How electrical systems gets inspected — and verified
On site — Physical Inspection
Your InterNACHI certified inspector physically examines every accessible electrical systems component with professional equipment, including moisture detection — plus thermal imaging when the optional upgrade is added.
In the report — Review & Verification
Every photo and reading from the electrical systems inspection is cross-referenced through our reporting system, and every finding is severity-rated before appearing in your report.
