My Arvada basement grew mold after the sump failed this spring. What is the correct order of work?

Water first, growth second, in documents as much as in labor. The failed event is photographed and the pit and pump documented, the sump system is repaired or replaced with its backup question answered, and only then does remediation scope from the moisture map: containment, removal of what the growth claimed, framing treatment, and drying verified by readings. Rebuilding before the source line is signed is how the same basement gets remediated twice. If a claim is involved, the pump is kept until the carrier answers, because in a sump city the failed pump is the event's central exhibit.
