After thousands of inspections across Nassau and Suffolk County, certain issues come up over and over. These aren’t rare anomalies — they’re predictable patterns tied to the age and style of Long Island’s housing stock.
Inadequate Attic Ventilation
The single most common finding across all price points. Poor ventilation leads to moisture buildup, premature roof deterioration, ice dams in winter, and excessive heat in summer. It’s inexpensive to correct once identified.
Water in the Basement
Long Island’s flat terrain and clay-heavy soil create chronic drainage challenges. Evidence of water intrusion — staining, efflorescence, fresh paint over masonry — shows up in a significant percentage of inspections.
Aging Electrical Systems
Federal Pacific and Zinsco panels are still in service in older Nassau County homes. Both have documented failure rates. Aluminum branch circuit wiring, common in 1960s and 70s construction, requires specific outlets and connections that many homes don’t have.
Deferred HVAC Maintenance
Filters not changed, ducts never cleaned, systems years past their service interval. A heating system that fires up isn’t necessarily a safe or efficient one. Your inspector will assess age, condition, and operation.
Grading and Drainage Issues
Soil graded toward the foundation instead of away from it channels water directly into the basement. Simple to fix, common to find, easy to miss on a casual walkthrough.
