  3. Which exact product line and thickness is quoted, not just the material name?
  4. Is house wrap included, and is it a standard wrap or a drainable one?
  5. Does the number assume one story, or did the bidder walk the whole house?
  6. What's excluded: a permit fee, sheathing repair, paint, or anything else billed only if it's found?
