Why is sewage cleaned differently from creek water?
Sewage carries bacteria and waste, so porous materials it touches usually cannot be cleaned to a safe standard and must be removed. Clean creek water, by contrast, can often be extracted and dried in place when the materials are sound.
Creek water is mostly silt and debris, and a crew can often clean and dry the materials it reaches. Sewage carries waste and bacteria, which soak into carpet, pad and porous drywall in a way that cannot be reliably cleaned.
The difference changes the scope. A crew that finds sewage removes the porous materials, disinfects the hard surfaces and dries the structure. It records each step so the homeowner and the insurer can see what was done and why.
How does a crew identify the water?
A crew identifies the water by its source, its smell, its color and the solids it carries, and it states what it believes the water is before it begins. When the source is unclear, the crew treats the water as sewage.
The first question is where the water came from. A backup through a drain points to sewage, while a flow across the yard points to surface water. The crew looks at the water itself, then checks the source, and it says what it sees.
If there is any doubt, the crew treats the water as sewage. That is the safer assumption, and it changes the cleanup in ways that protect the people in the house.
What about the carpet, drywall and furniture?
Carpet, pad, porous drywall and upholstered furniture that sewage has touched are usually removed. Hard surfaces such as tile and sealed wood can often be cleaned and disinfected.
Carpet and pad hold sewage in their fibers and cannot be cleaned to a safe standard once it has soaked through. Drywall that wicked the water is removed to the height the readings show, because it cannot be disinfected in place.
Furniture and stored items that the water touched are assessed one by one. Some hard items can be cleaned. Upholstered and porous items are usually discarded, and the crew records each decision.
What moves the price of sewage cleanup?
Price moves with how far the water spread, how many porous materials must be removed, how much cleaning and disinfecting is needed and how long the drying takes. The price is explained and approved on site before any work begins.
The first factor is the area the water reached, because each room needs closing off, cleaning and reading. The second is the amount of porous material that must be removed, which is often the largest part of the cost. The third is the cleaning and disinfecting of hard surfaces.
No figure is given on this page. The crew explains each factor for your house and states the scope and the price before work starts. The sewer line and the drain are cleared by a plumber, and that is a separate job.
What should the homeowner do until the crew arrives?
Keep everyone out of the affected room, keep pets away, turn off power to wet outlets you can reach safely, and avoid using household vacuums or fans. Photograph the water and the damage from the doorway.
Close the door to the affected room and keep children and pets away. Do not flush toilets or run water into the affected drain, since that can push more water back up the line.
Photograph the water and the damage from the doorway, without stepping into the room. Keep a note of the time you first saw the water and where it came from. The crew will ask for those details.
