I recently completed a Property Condition Assessment in Macon GA. There were several electrical panels used at a facility with improper panel types.

We preform Property Condition Assessments or Commercial Building Inspections here in the Southeast which includes Georgia, South Carolina, Alabama, Tennessee, Kentucky & Alabama. Southeast Building Consultants, LLC can evaluate all your electrical transformers, utilities, service panels, distribution, switch gears, fixtures and even your lighting.

NACBI (National Association of Commercial Building Inspectors & Thermographers) has experienced certified commercial inspectors & thermographers) all over the United States. If Southeast Building Consultants LLC does not perform Property Condition Assessments or Commercial Building Inspections in your State, we'd still be happy in putting you in contact with one of our close associates here at NACBI!
