5 Most Common Home Inspection Findings in Baltimore Area Homes

After hundreds of inspections across Baltimore City, Baltimore County, and surrounding Maryland communities, certain issues show up again and again.

1. Basement Water Intrusion

Baltimore’s older housing stock sits largely on block or stone foundations, and Maryland’s rainfall gives water plenty of chances to find its way in. We find evidence of past or active water intrusion in the majority of older Baltimore basements — efflorescence on block walls, water staining on floors, rusted HVAC equipment from past flooding.

2. Aging Electrical Panels and Wiring

Baltimore City has some of the oldest housing stock on the East Coast. Many homes still have original knob-and-tube wiring, 60-amp service panels, Federal Pacific Stab-Lok panels (documented safety concerns), or aluminum branch circuit wiring. Some insurers will not write policies on homes with Federal Pacific panels or knob-and-tube wiring.

3. Roof Issues

Depending on age and roofing type, we find granule loss, aging shingles, improper flashing around chimneys and skylights, and flat roof sections with ponding water. Roof replacement in Baltimore averages $8,000–$18,000 depending on size and material.

4. HVAC System Age and Condition

Heat pumps typically last 12–15 years; gas furnaces 15–20 years. In a market where homes change hands every 7–10 years, it’s common to find HVAC systems approaching or past their expected service life. Budget $4,000–$8,000 for replacement in the near term if the system is aging.

5. Deferred Maintenance

The most common finding across all inspections — peeling caulk, clogged gutters, wood rot at trim, loose handrails, inoperable windows. Individually minor, but collectively they tell a story about how the home has been cared for.
