The short answer

Health Risks of Sewage Backup

Raw sewage carries pathogens that can make you sick if you touch contaminated surfaces, inhale droplets, or ingest anything that has come into contact with the water. The longer the sewage sits, the higher the risk of bacterial and fungal growth. Porous materials like drywall, carpet, and upholstery can absorb sewage, trapping contaminants even after the visible water is gone.

Children, elderly individuals, and people with weakened immune systems face greater risk. If you feel unwell, see a doctor. The safest approach is to keep everyone out of the affected areas until a professional has assessed the situation and the cleanup is complete. Ventilate the space by opening windows and running fans, but do not use forced air if it might spread contaminants to clean areas.

  • Wear gloves and a mask if you must enter the area
  • Avoid touching your face or eyes
  • Wash your hands thoroughly with soap and water after any contact
  • Keep pets away from contaminated areas
  • Do not use water from the affected rooms for drinking or cooking
  • Remove any food that may have been exposed to sewage

Structural and Electrical Dangers

Sewage backup often comes with water that can seep into walls, floors, and electrical outlets. Water and electricity are a dangerous combination, so avoid using any electrical devices in wet areas. If the water has reached outlets or wiring, turn off the power at the main breaker if it is safe to do so, and contact an electrician.

Standing water can also weaken floors and ceilings, increasing the risk of collapse. The subfloor and under-house areas may be affected, especially in homes with crawl spaces. Do not walk on sagging floors or enter rooms where the ceiling is bulging. Local water damage pros can assess the structural integrity and recommend the right repairs.

Immediate Steps You Should Take

First, stop using water in your home to prevent more sewage from coming in. If you can locate the shutoff valve for your sewer line, turn it off. In Frisco, keep the location of your main shutoff valve written down so you can act quickly in an emergency.

Next, document the damage for your insurance company. Take photos and videos of the affected areas, but do not put yourself at risk. Then, contact local water damage pros to handle the cleanup and extraction. They have the equipment to remove contaminated water and dispose of it properly. Avoid trying to clean it yourself, as that can spread bacteria and cause secondary damage.

When You Can Reoccupy the Home

You should not return to the affected areas until the sewage has been removed, the surfaces have been cleaned and disinfected, and the materials have been dried thoroughly. The pros will use structural drying and dehumidification to reduce moisture levels and prevent mold growth. This process can take several days, depending on the extent of the damage.

Even after the visible water is gone, hidden moisture can remain in walls and subfloors. A moisture mapping inspection can help confirm that the area is dry. Do not move back in until the pros say it is safe. If you have health concerns, consult your doctor. Your insurance policy may also require you to wait until the property is deemed habitable.

  • Wait for the pros to complete the cleanup and drying
  • Check for any lingering odors that might indicate trapped moisture
  • Ask the pros about the results of moisture testing
  • Consider replacing porous materials like drywall and carpet
  • Keep the area ventilated during the drying process

Preventing Future Sewage Backups

Once the cleanup is done, take steps to reduce the risk of another backup. Avoid flushing anything other than toilet paper, and never pour grease or oil down drains. If you have trees near your sewer line, roots can invade and cause blockages. A plumber can inspect your pipes and recommend preventive measures.

Heavy rains can overload sewer systems, especially during storms. Consider installing a backwater valve to prevent sewage from flowing back into your home. Also, keep your gutters and downspouts clear to direct rainwater away from your foundation. Regular maintenance can go a long way.

Water damage does not wait

Frequently asked questions

Can I clean up a sewage backup myself?

Cleaning sewage yourself is risky. The water contains harmful bacteria, and improper cleaning can spread contamination. The pros have the right equipment and disinfectants to do the job safely. Leave it to them and focus on keeping everyone away from the affected areas.

How long does sewage cleanup take?

The duration depends on how much water is involved and how far it spread. A small backup might take a day or two, while a larger one could take several days. The pros will need to remove the water, clean and disinfect, and then dry the structure completely. Ask them for an estimate after they assess the damage.

Will my insurance cover sewage backup damage?

Policies vary, and your insurer decides what is covered. Some policies include sewage backup coverage, while others require a separate rider. Review your policy and contact your insurance company to understand your coverage. Document all damage with photos and keep receipts for any temporary housing expenses.
