Frequently Asked Questions

What does a home inspector check?

Structure, roof, exterior, HVAC, plumbing, electrical, insulation, ventilation, interior, and foundation. Inspectors do not move furniture or appliances. They look for defects, safety hazards, and deferred maintenance.

Should I attend the inspection?

Yes β€” always attend if possible. Walk through with the inspector, ask questions, take notes. You'll learn about your home's systems and maintenance needs. The report is technical; the walkthrough gives context.

What is not covered in a standard inspection?

Pools, spas, wells, septic systems, mold (unless visibly present), asbestos, lead paint, and specialized systems (alarm, intercom). These require separate inspections. Older homes may need specialized inspections for板岩, knob-and-tube wiring, or polybutylene pipes.
