Home inspectors thoroughly examine the basement or crawl space for signs of moisture, which can lead to mold growth and damage to the foundation. They also assess structural problems, such as cracks in the walls or floors that might indicate shifting or settling of the building.
Additionally, they check the insulation to ensure it is adequate for energy efficiency and comfort. Inspectors also look for additional issues, such as electrical wiring problems, and plumbing leaks, to provide a comprehensive evaluation of the space's condition.
