FAQ
Sewage FAQ.
Is a sewage backup dangerous?
Yes — it's Category 3 black water carrying bacteria and viruses. Keep people and pets away from the area and call us right away. We contain the space, remove and sanitize to the IICRC S500 standard, and verify everything is safe before any rebuilding begins.
