The process of inspecting the interior of a structure is very similar across all construction types. Interior inspections can be more or less important depending on the type of construction used in the structure as well as the number of conducive conditions to infestation that are associated with the structure. For example, a pier-and-beam house with solid concrete piers, easy accessibility to the crawl space and no conducive conditions may not need an interior inspection at all. Conversely, an interior inspection is vital in an historic French Quarter building using floating-slab construction with common walls on either side.
A good rule to use is: The less that you can see outside, the more that you need to see inside.
Based on this rule, it may be necessary for the inspector to access all of the rooms in a structure including closets, storage rooms and attics.
Examine door and window frames for signs of infestation. Damaged wood often appears wavy and may sound hollow when tapped. During the annual mating season, the termites may build swarm castles from the frames that are easily visible.
Similar to door and window frames, baseboards and other molding will often appear wavy and sound hollow when tapped if they have been damaged by termites.
Termites can damage many types of wood flooring. Look for damage and buckling, and feel for weak areas as you walk around. Water damage can appear similar but will not sound hollow when tapped. It may be necessary to remove floor coverings to reveal the damage.
Attics can be a very important part of an interior inspection for two main reasons:
Attics can be very dangerous places.
