Sewage backup is the most dangerous type of water damage. Category 3 water contains bacteria, pathogens, and viruses. Every porous material in contact must be physically removed; no exceptions. Your family's health depends on doing this correctly.
Water damage comes in different forms. Category 1, caused by clean water from a burst pipe, is primarily a drying issue. It requires drying and not much else. Category 3 is a more complex problem. It involves sewage, black water, and outside flooding, and poses a biohazard.
Category 3 water can contain fecal bacteria, E. coli, Hepatitis A, and other pathogens. These can cause harm even if you just touch it, swallow it, or breathe it in. In Orlando's warm climate, these pathogens multiply quickly. Exposure can cause stomach problems or respiratory infections. For kids, older adults, or people with a weak immune system, the risk is higher.
Never attempt DIY sewage cleanup. It's not safe with just a shop vac and rubber gloves to protect you from Category 3 pathogens. Trained workers must wear full protective gear. This includes Tyvek suits, respirators, and nitrile gloves. They use the right sanitizing products. They also dispose of biohazardous materials correctly.
Anything porous that touched sewage water can't just be cleaned. It has to be physically removed and thrown out as biohazard waste. This includes carpet and padding. It also includes drywall up to 12 to 18 inches above the waterline. Insulation, wood baseboards, and particleboard cabinets are included. Any porous materials that soaked up contaminated water are included too.
This isn't something we cut corners on to save money. It's the actual standard, set by IICRC S500 and the Florida Department of Health. If a contractor says you can just "dry in place" sewage-soaked drywall, they might be wrong. Treating it with antimicrobials won't fix the problem. They're either inexperienced or dishonest.
Standard HO-3 policies do NOT automatically cover sewage backup. Coverage requires a separate sewer backup endorsement, which must be purchased before the event. The cost is typically $40–$80 per year — far less than the average $7,000–$25,000 sewage backup restoration. Check your policy declarations page for "water backup and sump overflow" coverage. If you don't have it, add it at your next renewal.
Category 3 biohazard requires immediate professional help. Don't try to clean it yourself. Our trained crews wear full personal protective gear. They also carry the right tools for safe disposal. We are available around the clock.
