Sewage Cleanup & Removal in Denver, CO

Cleaning up after a sewage backup is about far more than removing what you can see. Because sewage is highly contaminated and soaks quickly into porous materials, thorough cleanup and removal means decontaminating the entire affected area and safely removing everything that cannot be salvaged. Critical Restoration provides complete sewage cleanup and removal across Colorado, restoring a safe, sanitary environment to your home.

Our IICRC certified crews follow strict protocols for handling Category 3 contamination, and we work closely with your insurance company throughout.

Understanding Sewage Contamination

Sewage is classified as Category 3 water, or black water, the most contaminated category. It carries bacteria, viruses, and parasites capable of causing serious illness, and it penetrates carpet, pad, drywall, insulation, and subflooring. Effective cleanup requires identifying everything the contamination has reached, not just the surfaces where it is visible, and treating the area to a safe, sanitary standard.

Our Sewage Cleanup and Removal Process

  • Assessment of the full extent of the contamination, including hidden areas
  • Containment to prevent the spread of contamination during the work
  • Removal and extraction of sewage and contaminated water
  • Removal of porous materials that cannot be safely decontaminated
  • Cleaning, sanitizing, and antimicrobial treatment of all affected surfaces
  • Drying and verification that the area is safe and sanitary

Decontamination and Sanitizing

The heart of sewage cleanup is decontamination. After removing the sewage and unsalvageable materials, we clean and sanitize all affected surfaces and apply antimicrobial treatments to eliminate the bacteria and pathogens sewage leaves behind. This step is what restores the space to a safe, healthy condition, and it is why professional cleanup is so important.

What Can Be Saved and What Must Be Removed

Because sewage is so contaminated, porous materials that have absorbed it, such as carpet, pad, and affected drywall and insulation, usually must be removed, since they cannot be fully decontaminated. Non porous surfaces and many belongings can often be cleaned, sanitized, and saved. We assess every material carefully and remove only what must go, keeping your costs down while protecting your health.

Frequently Asked Questions

  • Why does sewage require such thorough cleanup?
    Because it is Category 3 black water, the most contaminated type, carrying pathogens that cause serious illness. It also soaks into porous materials, so cleanup must address everything the contamination has reached and decontaminate the area to a safe, sanitary standard.
  • Can my belongings be saved after a sewage backup?
    Non porous items and many belongings can often be cleaned, sanitized, and saved, while porous materials that absorbed sewage usually must be removed because they cannot be fully decontaminated. We assess each item individually.
  • How do you make sure the area is truly safe afterward?
    We remove contaminated materials, clean and sanitize all affected surfaces, apply antimicrobial treatments, and verify the area is dry and sanitary. This thorough decontamination is what restores a genuinely safe, healthy environment.
  • Is sewage cleanup covered by insurance?
    It is often covered, though many policies require a sewer backup endorsement. We document the contamination and work thoroughly and coordinate closely with your insurer to support your claim.
  • How long does sewage cleanup take?
    It depends on how far the contamination spread and how much material must be removed. Cleanup and decontamination often take a few days, followed by drying. We provide a clear timeline once we assess the full scope.
