The short answer

Safety First

Before any cleaning begins, the area is sealed off to prevent cross-contamination. Household members and pets stay away from the affected zone. The pros wear protective suits, gloves, and respirators to avoid contact with pathogens.

The space is ventilated, but only with exhaust fans that push air outside, not into other rooms. Any porous items like carpets, drywall, and upholstery that cannot be fully cleaned are removed and disposed of properly. This step is critical because sewage can soak deep into materials.

  • Turn off HVAC to stop spreading contaminants
  • Remove all porous materials that absorbed sewage
  • Set up containment barriers with plastic sheeting
  • Use negative air pressure to keep airborne particles contained
  • Wear full protective gear, including boots and eye protection
  • Have a disposal plan for contaminated waste

Remove Standing Water

All standing sewage and water are extracted using powerful pumps and wet vacuums. This is done quickly to prevent further soaking into floors and walls. The pros work from the farthest point of the backup toward the exit to avoid tracking.

After the bulk water is gone, they check for trapped moisture in wall cavities and under flooring. Moisture meters help identify hidden saturated areas. Any remaining wet materials are removed or dried with air movers and dehumidifiers.

  • Use submersible pumps for deep water
  • Wet vacuums for residual water on surfaces
  • Moisture meters to find hidden wet spots
  • Remove baseboards and lower wall sections if wet
  • Set up air movers to circulate air
  • Dehumidifiers to pull moisture from the air

Clean and Disinfect

All hard surfaces are washed with a detergent solution to remove organic matter. Then a disinfectant registered as effective against bacteria and viruses is applied. The disinfectant needs to stay wet on surfaces for the time specified on the label to work fully.

The pros pay special attention to cracks, crevices, and joints where sewage can hide. They use brushes and sprayers to reach every spot. After disinfection, surfaces are rinsed and dried with clean water to remove any chemical residue.

Dry Thoroughly

Drying is a major part of the cleanup, because moisture left behind can lead to mold and structural damage. Industrial dehumidifiers and air movers are placed to dry the area completely. This can take several days, depending on the extent of the backup.

The pros monitor moisture levels in walls, floors, and air until readings are back to normal. In a humid subtropical climate with hot rainy summers, drying is even more important to prevent secondary issues. They may also use antimicrobial treatments on wood and concrete.

Restore and Prevent

Once the area is clean and dry, repairs begin. This includes replacing drywall, flooring, and other materials that were removed. The pros also check the plumbing system to find the cause of the backup, such as a clogged line or a failing sewer pump.

They recommend steps to reduce future risks, like avoiding flushing non-degradable items and having the sewer line inspected regularly. If you live in Bonita Springs, keep your shutoff valve location written down and know how to use it in an emergency. After everything is restored, a final inspection ensures the area is safe and livable.

Frequently asked questions

How long does the cleaning process take?

The timeline depends on the size of the backup and how much material is affected. A small backup can take a day or two, but a larger one with deep saturation may take several days. Drying alone can take up to a week or more.

Do I need to throw away furniture touched by sewage?

Porous items like mattresses, upholstered sofas, and carpeting often cannot be fully cleaned and are usually discarded. Non-porous items like plastic and metal can be cleaned and disinfected. The pros will assess each item and advise you.

Will my insurance cover the cleanup?

Policies vary, and your insurer decides what is covered. Sewage backup coverage is often a separate add-on to a standard homeowners policy. Check your policy documents and talk to your insurance company to understand your coverage and any limits.
