Sewage backups and human waste contamination create serious health hazards that require immediate professional attention.

Our emergency response team is available 24/7 to safely remove contamination, sanitize affected areas, and help restore your property.
Raw sewage contains bacteria, viruses, parasites, and other harmful pathogens that can quickly spread throughout a property. Whether caused by plumbing failures, sewer backups, flooding events, damaged septic systems, or long-term neglect, sewage contamination should always be treated as a biohazard situation.
Exposure to contaminated water and waste materials can create significant health risks for occupants, property owners, maintenance personnel, and restoration workers. Proper cleanup requires specialized equipment, containment procedures, personal protective equipment, and professional decontamination methods.
At 911 Hazmat Cleanup, we provide comprehensive sewage cleanup services designed to safely remove contamination, sanitize affected areas, and help restore healthy indoor environments.
Many sewage events involve contamination that extends well beyond visible waste materials. Porous surfaces, flooring systems, subfloors, wall cavities, insulation, HVAC systems, and structural materials may all be affected.
Simply removing visible contamination does not eliminate bacteria, viruses, or odor-causing organisms that may remain behind. Proper remediation requires a systematic process that addresses contamination at its source while reducing the risk of future health concerns.
Our sewage cleanup services may include:
In many situations, sewage contamination is accompanied by secondary concerns such as mold growth, bacterial amplification, insect activity, and indoor air quality issues. Addressing these factors early can help prevent additional damage and support a safer recovery process.
Sewage contamination can occur in a wide variety of residential, commercial, and industrial environments.
Our team frequently responds to situations involving:
In severe cases, contamination may remain undiscovered for extended periods of time, creating significant environmental and structural concerns. Professional remediation helps ensure contaminants are properly removed while reducing exposure risks and restoring affected areas to a safer condition.
Because every sewage loss is unique, our team evaluates each situation individually to determine the extent of contamination, affected materials, environmental concerns, and appropriate remediation procedures.
Sewage contamination frequently affects more than the immediately visible areas of a property. Moisture migration and contamination can spread beneath flooring systems, into wall assemblies, insulation materials, crawlspaces, and ventilation systems.
If not properly addressed, these conditions may contribute to ongoing odor issues, microbial growth, material deterioration, and indoor environmental concerns.
Our environmental risk management approach focuses on identifying contamination pathways, assessing affected materials, and implementing remediation procedures designed to reduce both immediate and long-term risks.
Raw sewage should always be considered a biohazard due to the presence of potentially dangerous microorganisms and contaminants.
Potential concerns may include:

They made a very difficult situation much easier to deal with. Kimberly and her team were very communicative, informative, and flexible with us. Pricing was transparent and fair, much better than other companies who bid the work. Would absolutely call them again.
Spencer GlasgowAmazing, quite thorough in their work. We called them to cleanup rodent droppings. Left the garage very clean and prestige. Very professional. They cleaned the inside of all the garage cabinets. Every step was explained and photographed and shared with us. Look no further.
Minal DaveFrom the start, 911hazardcleanup was professional and thorough. The clean up team did an amazing job in what was a hoarder house situation. They went above and beyond to insure that the living situation was brought back to safe and sanitary conditions. I cannot recommend them highly enough.
Gary LitkeThe 911 crew, from Kimberly and Sean to the clean-up crew, led by Alejandro, were professional and thorough. Kimberly kept me up-to-date regarding scheduling and necessary documents. The clean-up crew was very thorough and even had time to add another small section of flooring. I highly recommend 911 Hazmat Clean-up for any task!
Karen ZDependable. Professional. And thorough. I know when they’re on the job it’s going to be done right.
Robert AsherVery nice people to work with!
Jesse JStop your search right here! You do not need to go any further. 911 Hazmat Cleaners will take care of you for a very reasonable price in a very difficult situation. I had an unattended death and level 4 hoarder clean up. I was overwhelmed! 911 Hazmat Cleaners was $7,000 cheaper than the other bids. They were perfect in everyway. You couldn’t believe the before and after photos. And the smell afterwards was amazing! They also bought lunch for my husband and me everyday we were there with them. Just mention to the other companies that you are going to talk to 911 Hazmat and watch their faces fall because they know. We were so happy we tipped the guys a hundred dollars each. You will be happy too if you have to use them!
Deborah ChaseEveryone with whom I worked with at 911 Hazmat was above expectations in satisfaction for the client, consideration for the neighbors, efficiency in their work, positive and supportive throughout the 18 days to complete the cleanup, trustworthy, and so thoughtful to me while I was grieving for my sister and dealing with a toxic cleanup. The documentation of work they did every day with pictures and amounts of trash dumped was especially helpful since I could not physically be onsite once worked started on the property. They give an estimate and stick with it. This company is the BEST.
Kathie CongdonThis company was terrific to work with. They got on the job immediately and did an outstanding job and stayed with it until completion.
