Why is sewage water handled differently from clean water?
Sewage carries bacteria, viruses and waste, and it can leave contamination in porous materials that is not removed by drying. Water from a sewer backup is handled as contaminated from the first pass, so the people working on it use protection and the materials it touched are judged by a stricter standard.
The first concern is the health of the people in the building and the people doing the work. The water should not be touched with bare hands, and it should not be splashed onto skin or into the eyes. Children and pets are kept out of the area until it has been cleaned and dried.
The second concern is the materials. Carpet pad, insulation, unfinished drywall and wood can hold contamination after they dry, and they are often removed rather than cleaned. The decision on each material is recorded so the reason is clear.
Can carpet and pad that were in sewage be saved?
Carpet and pad that were in sewage are usually removed, because the pad is porous and holds contamination below the surface. A carpet that is made of a dense material may sometimes be cleaned and kept, but the decision is made after the carpet is lifted and the pad is looked at.
A carpet that is lifted and cleaned can still hold contamination in the pad and the backing. The technician checks the subfloor underneath and decides whether it can be disinfected or must be replaced.
The removal is recorded with the material, the room and the reason. The record matters for the insurer and for a later repair, because the material cannot be recovered once it has been thrown away.
What should I do with my belongings after a sewer backup?
Keep belongings out of the water, move the items that are not wet to a dry room, and photograph everything that was touched before it is moved. Wet porous items such as paper, upholstery and bedding are usually removed, while hard items can often be washed and kept.
Do not try to wash clothing or linens in the house before the technician has checked the area, because the contaminated water can spread through the laundry. Bag wet items and keep them apart from the rest of the house until a decision is made.
The list of belongings and the photographs are useful to the insurer. Write down what was lost, what was saved and what was removed, and keep the bags for inspection if they are asked for.
Does a sewer backup change the claim?
This site cannot say what a policy covers, and a policy may treat backup water differently from other water damage. The insurer decides, and the technician keeps the record of the source, the water and the materials removed that the insurer will ask for.
Backup is often handled by a separate part of a policy, so do not assume it is included. Ask the insurer what your policy says about sewer and drain backup, and keep the record of the cause as it was found.
The technician records the source of the water as it is seen on site, and does not decide the coverage question. The record is the evidence of what happened, and the policy and the insurer decide the rest.
What does sewer backup cleanup cost?
This site does not publish prices. The cost moves with how far the water spread, how many materials must be removed, how many rooms are affected and how long the drying runs. The scope is explained on site and approved before any work starts.
Contaminated water costs more to remove and treat than clean water, and materials that must be removed add to the scope. A basement with several rooms affected is a larger job than a single bathroom.
Ask for the scope in writing with each material and each room listed, and with the reason for each removal. A written scope is the basis for comparing firms and for the claim.
