What Does a Home Inspector Actually Look At? A Room-by-Room Breakdown
If you’ve never hired a home inspector before, you might wonder what actually happens during those two to three hours on-site. The short answer: a licensed inspector examines hundreds of individual components across every accessible area of the home. Here’s exactly what that looks like, room by room.
The Exterior
The inspection begins outside. The inspector walks the entire perimeter, checking the condition of the roof covering, gutters, downspouts, and flashing. They look at the grading around the foundation — the ground should slope away from the house to keep water out of the basement or crawl space. Siding, trim, windows, doors, driveways, walkways, and decks all get evaluated for damage, deterioration, or safety issues.
The Roof
When safe and accessible, inspectors walk the roof or observe it closely from a ladder. They’re looking at the age and condition of shingles, evidence of missing or lifted material, the condition of flashing around chimneys and vents, and signs of past or active leaking. Roof issues are among the costliest repairs in any home — catching them before closing is worth every penny of the inspection fee.
The Attic
The attic reveals a lot about a home’s health. Inspectors check for proper insulation levels, adequate ventilation, signs of moisture or mold, and whether the roof structure is sound. They also look for evidence of pest activity, improper bathroom exhaust fans venting into the attic space (a very common problem in Maryland homes), and any DIY electrical work tucked up there out of sight.
The Basement and Foundation
Foundation cracks, water staining, efflorescence (white mineral deposits on concrete), and musty odors all tell a story about how a home handles water. Inspectors look at the type of foundation — poured concrete, block, or stone — and note any structural concerns. In Maryland, basement water intrusion is one of the most commonly reported issues in older Baltimore-area homes.
The Kitchen
Inspectors test all accessible outlets, check under-sink plumbing for leaks, run the garbage disposal, test the dishwasher’s drain cycle, operate the range hood, and look at the exhaust fan venting. They verify GFCI protection is present within six feet of the sink. Cabinet condition and countertop integrity are noted but typically considered cosmetic unless they indicate a larger problem.
Bathrooms
Every bathroom gets a full check: toilets tested for stability and proper flushing, faucets run to check water pressure and drainage speed, exhaust fans checked to make sure they actually vent outside, and tile and caulking inspected around tubs and showers for gaps that could allow water intrusion into the wall cavity. Missing or deteriorated caulk is one of the leading causes of expensive bathroom water damage.
Electrical System
The electrical panel is one of the most important stops. The inspector checks the panel brand (some older brands like Federal Pacific and Zinsco have known safety issues), verifies proper breaker sizing, looks for double-tapped breakers, and ensures the panel is properly labeled. Throughout the home, outlets are tested, AFCI and GFCI protection is verified where required, and any visible wiring concerns are documented.
Plumbing
The inspector identifies the type of supply and drain piping — important in older Baltimore-area homes where galvanized steel or even lead pipes may still be present. They check the water heater’s age, condition, pressure relief valve, and proper venting. Every accessible fixture is tested. Slow drains, water pressure problems, and signs of past leaks are all noted in the report.
Heating and Cooling
The HVAC system gets a full operational check. The inspector runs the system, checks the air filter, inspects accessible ductwork, verifies proper airflow to each room, and evaluates the condition and approximate age of the equipment. In Maryland’s climate, both the heating and cooling systems are essential — a failing heat pump or aging furnace is a negotiating point every buyer should know about before closing.
What the Inspection Doesn’t Cover
A standard home inspection is visual and non-invasive. Inspectors don’t remove drywall, move furniture, or operate systems that are shut off. Specialized testing — radon, mold, water quality, sewer scope, oil tank location — requires separate services. If your inspector flags concerns in any of these areas, adding the appropriate test is always the right call.
