Most projects finish in 5–21 days. Three to five days for emergency extraction, demolition of affected porous materials, antimicrobial treatment, and structural drying. One to three weeks for the rebuild (drywall, paint, flooring) once the area passes a post-remediation verification. Larger finished-basement losses can run longer.
Why can't sewage-soaked carpet be cleaned and reused?
Carpet pad and the underlying materials are porous and absorb sewage water along with the bacteria, viruses, and parasites it carries. The IICRC S500 standard (the industry standard for water restoration) requires that Category 3 contaminated porous materials be removed, not cleaned in place — there is no reliable way to disinfect a carpet pad to a safe condition once sewage has soaked through. The decision is documented and shared with your adjuster; replacement carpet and pad are part of the reconstruction scope.
Does my homeowners policy cover sewage backups?
Most standard Colorado homeowners policies do not cover sewer or drain backups under the base policy — coverage requires a separate endorsement that is purchased annually, often with its own sub-limit ($5,000, $10,000, or $25,000 are common). Check your declarations page for an entry like 'sewer backup' or 'water back-up of sewers and drains.' If you are not sure, call your agent before authorizing any cleanup; we can also help interpret the dec page if you bring it to the inspection.
How do you keep the contamination from spreading to the rest of the house?
Containment is set on day one: 6-mil polyethylene barriers seal the affected area from the rest of the home, the area is run under negative air pressure with HEPA-filtered air scrubbers, and a dirty-zone / clean-zone protocol controls how crews move in and out. PPE includes Tyvek suits, respirators, and gloves; disposable booties are worn over boots and removed at the containment border. The adjacent rooms stay habitable for the family while the work is underway.
How long after a sewage backup is it safe to be in the area?
After the cleanup is complete and the area passes a post-remediation verification (visual inspection plus, in some cases, surface or air sampling), the space is safe for unrestricted occupancy. During the cleanup the contained zone is off-limits except for crew in PPE. We provide a written clearance at the end of the remediation phase, before reconstruction begins.
What happens to my contents after a sewage backup?
Hard goods (metal, sealed plastic, glass, finished wood) can usually be cleaned and disinfected on site or at our contents facility. Soft goods (upholstered furniture, mattresses, fabric, paper, photos, books) that contacted Category 3 water are typically a total loss — there is no reliable way to disinfect them to a safe condition. We inventory each item with you, document its disposition for the claim, and dispose of contaminated items per local hazardous-waste regulations.
What causes sewer backups in Denver homes?
The common causes in the Denver metro are tree-root intrusion in the lateral sewer line between the house and the city main, pipe failure in older homes (cast iron and clay laterals fail eventually), grease or wipes blocking the main, and city sewer overflows during heavy rain in some older neighborhoods. After the cleanup we recommend a sewer-line camera inspection to identify the root cause; without that step the backup is likely to recur and the next claim may be denied as a maintenance issue.
Can I clean up a small sewage backup myself?
We do not recommend it. Even a small Category 3 loss involves pathogens that can survive ordinary household cleaning; the affected materials need to be removed and disposed of as biohazard waste, the area needs antimicrobial treatment, and the structure needs to be dried under monitoring to prevent secondary mold growth. Most homeowners policies that cover sewer backup also pay for professional cleanup; the insurance value of doing it correctly almost always exceeds the cost of going it alone.
Will I need a sewer-line repair as well as cleanup?
Sometimes. The cleanup addresses the contamination inside the home; the source line repair is a separate scope handled by a licensed plumber. If the sewer line failed (root intrusion, broken pipe, collapse), the repair must happen before water service is restored to the affected fixtures. We coordinate with a plumber on every Category 3 loss and can help you sequence the work so the repair, the cleanup, and the rebuild happen in the right order.
