What We Inspect and Why

A home inspection is a visual examination of the home's major structure, systems, and components that are visible and safely accessible. Buying a home is typically the biggest investment you will ever make, so it's important to get a home inspection because the inspector can find and document defects that may or may not be obvious to you as a prospective buyer.  Such defects can range from simple replacements or repairs to severe damage or safety and health concerns.
