The crawl space is one of the most crucial areas a home inspector should inspect. This particular opening isn't exactly large, but trust us, our inspector Rick has gotten into MUCH smaller spaces (attic openings are especially fun!). A home's crawl space often contains HVAC components, exposed plumbing pipes, insulation, and vapor barriers and/or other encapsulation materials. All of these items should be carefully inspected to ensure they are functioning as intended. Signs of trouble can also be spotted in the foundation and in crawl spaces that are wet and musty - dry is what he's looking for!

HVAC TIP: Check to make sure there are no gaps! Gaps in the metal exterior duct that leads from the HVAC to the home lets heat escape and lets water in. It can also contaminate the air supply with undesirable fungal growth (think mold). The metal box should be flush and sealed to the home to prevent these serious issues from occurring.
