Welcome to Middle Department Inspection Agency, Inc.  

MDIA is an independent inspection company, which is an outgrowth of the Middle Department Association of Fire Underwriters, an organization of fire and casualty insurance companies that began making inspections in Pennsylvania and Delaware in 1883. We proudly boast a continuous involvement in the inspection industry, entering our third century, operating in six states in the mid-Atlantic region.


Since our inception in 1883, our reputation and capabilities have grown to include a full range of safety inspection services, including plan review, building, plumbing, fire protection and electric.


Our highly skilled and specialized inspectors are dedicated to accurate and efficient evaluations to ensure safety and compliance with state ordinance and law. 

Benjamin Franklin said, "An ounce of prevention is worth a pound of cure!"  Construction Inspections are that ounce of prevention.  It is all too easy to feel inconvenienced during the inspection process, but the inspection process has been designed to not only protect your property, but your life as well.


Inspection codes have been developed over decades with the help of thousands of people in the construction business.  Inspection codes change through a continuing cycle of submittal, review and adoption.
