Sewage backup in our finished basement on a Sunday night. They were on-site within 90 minutes, in full PPE, and had it cleaned and decontaminated by Tuesday. Hope we never need them again, but if we do, no question who to call.

Sewage Cleanup — FAQ
Yes. Sewage is Category 3 water and presents immediate biological hazard. We respond 24/7 and recommend evacuating the affected space until decontamination is complete.
Coverage depends on policy and cause. Many policies cover sudden backups when a sewer/drain backup endorsement is in place. We document everything to support the claim.
