Do I need professional cleanup after a sewage backup?

Yes—professional cleanup is recommended after a sewage backup because sewage (Category 3 “black water”) contains harmful bacteria, viruses, and chemicals that require specialized handling. Most backups stem from a blocked drain or failed sewer line that pushes contaminated water into living areas, where improper DIY cleanup can spread microbes and odors deeper into the home. A trained team will identify the source and contamination level, extract water, remove unsalvageable materials, dry and dehumidify the structure, and disinfect with hospital‑grade products while coordinating with your insurer. Our IICRC‑certified team serves the Denver area, including homeowners in Littleton, and provides 24/7 rapid emergency response.

Call a pro right away if you notice:

• Standing sewage or strong sewage odor indoors
• Contamination touching carpets, drywall, or insulation
• Repeated backups or wastewater coming from a floor drain

Keep people and pets out of affected areas and do not attempt DIY cleanup of sewage‑soaked materials. <br/> Updated: 2026-05-07 <br/> Need help in Littleton, CO? Call (303) 237-4406 or book online.
