What to ask, and why

Will the rebuild be rushed and sloppy?
Ask how work is inspected, which permits apply, and how the punch list is handled before the final payment.
What if materials don't match?
Older trim and tile may be discontinued. Approve samples first so there are no surprises when it goes in.
Can upgrades be added?
Yes, usually paid as the difference in cost. Agree on upgrades in writing before work starts.
Who handles insurance supplements?
Usually the contractor documents conditions found during repairs, often in Xactimate, for your adjuster; your insurer decides. Ask who will prepare it.
Does it matter if my address is Littleton but I'm in the county?
Yes. Permits may come from the City of Littleton or Arapahoe, Jefferson, or Douglas County.
