I inspected the attic for a New Construction inspection today and around half of the insulation appeared dirty, such as from air movement. The other half-ish was bright, clean pink-colored (as expected). While summarizing my findings, my client/buyer had taken similar pictures of the dirty insulation when doing a pre-drywall walk-through with the builder and shared them with me. He was concerned about it (and they wouldn’t let him perform a pre-drywall inspection).
Is there a new dirty looking insulation being installed in new homes that I’m not aware of? I’m not sure how to write a narrative for this one other than what I observed. Such as: I observed what appeared to be insulation affected by excessive air movement and appeared dirty.
