Sewer Backup

Sewer Backup Cleanup: what it covers

Quick answer

Sewer backup cleanup removes sewage that has come up through a floor drain, toilet or laundry tub, then cleans, disinfects and dries the affected room. Syracuse Water Damage Restoration takes sewer backup calls around the clock in Syracuse and Onondaga County, and a crew is sent as soon as one is free.

Sewage is not ordinary water. Water that has come up through a drain carries bacteria and other material that can make people sick, and it cannot be treated the way clean water is. A backup in a basement is a job for people with the right protective equipment and a plan for every surface the water touched, not a job for a mop and a fan.

Syracuse homeowners often find a backup after a heavy storm, when the sewer and the drain system are carrying more than they were built for. The sewer water rises through the lowest opening in the house and spreads from there. A crew arrives with the equipment to remove it, and the first thing it asks is where the water came up and whether the drain is still running. Call (833) 490-5225 for a crew, then keep people out of the room until one arrives.

Why does sewage come up into a Syracuse basement?

Sewage comes up into a basement when the drain system cannot carry its flow, usually because a line is blocked or the public system is full during heavy rain. The lowest drain in a house is the first place the water shows.

A drain carries waste away by gravity. When a line is blocked by roots, grease, a collapsed section or debris, the flow has nowhere to go and it rises. The basement floor drain sits lowest in the house, so the water appears there before it appears anywhere else.

The city's own material on Onondaga Creek describes the creek channel as engineered for combined sewage and storm flows. Where a system carries both, heavy rain can fill the pipes and push water back toward the buildings that sit at the bottom of the line. That is one reason a backup can start during a storm rather than from a blocked fixture.

What does a crew do to clean up sewage?

A crew removes the standing sewage, takes out the solids and the soaked porous material, cleans and disinfects the hard surfaces, and dries the structure. Each step is recorded so the owner and the insurer can see what was done.

The technician wears gloves, eye protection, boots and, where the water is heavily contaminated, a respirator. The standing water is pumped into a holding container and carried off for proper disposal. Solids and soaked paper are bagged on site and removed.

Hard surfaces are cleaned with a detergent first, so the soil is lifted, and then treated with a disinfectant that is suited to sewage. Porous materials such as carpet, pad, the lower part of drywall and insulation are removed where they have taken on the water, because a cleaning cannot reach what is inside them.

  • Protective equipment worn for every entry into the water
  • Standing sewage pumped and carried off for disposal
  • Solids and soaked material bagged and removed
  • Hard surfaces cleaned, then disinfected
  • Porous materials removed where the water has soaked in
  • The room dried to readings and the readings logged

Can a sewer backup be prevented?

A backup can often be reduced by keeping drains clear, by avoiding fixture use during a storm and by having a backwater valve or a backup device assessed by a plumber. No method removes the risk entirely.

Running a lot of water through the house during a heavy rain adds to the flow in the line. Waiting until the storm passes before running the washer or the dishwasher can lower the risk of a backup at a basement fixture. Keep grease out of the drains and do not flush wipes or paper towels, which tangle in the line.

A plumber can assess whether a backwater valve or a standpipe is suitable for a particular house. The valve is installed on the sewer line and closes when the flow reverses. Whether a valve is needed or practical depends on the house and the line, so ask a plumber for an assessment rather than relying on a general answer.

What do you tell the insurer about a sewer backup?

Tell the insurer the time you found the water, where it came up, and what you saw. Photographs before cleanup and a written record of the readings are the most useful papers you can keep.

Backup is handled under different terms than many other water events. Some policies exclude sewer or drain backup unless a separate endorsement is held, and the wording of the policy decides. Read the policy before the claim, and ask the insurer to show the backup terms in writing.

Keep the crew's note, the readings, the list of materials removed and the invoices. The New York State Department of Financial Services is the state regulator for insurers, and questions about how a claim is handled can be raised with it.

How long does a sewer backup take to dry out?

Drying a sewer backup usually takes several visits over a few days, because the water has soaked into the wall base and the subfloor. The drying ends when the readings reach a dry level, not on a fixed day.

The first visit removes the water and the solids and starts the equipment. The second and later visits move the equipment, take new readings and decide whether another material must come out. A wall that reads wet at the base may need a section cut back to dry the cavity.

Odour is often the last thing to leave. A room that still smells after the readings are dry may need a second cleaning or a closer look at a cavity. The crew notes any area it could not reach.

Warning signs

Signs you need sewer backup cleanup

Do not enter sewage-filled rooms without gloves and eye protection, and do not run any fixture until the line has been cleared. Keep children and pets away from the wet area, and wash hands and skin that touch the water.

  • Water rising in a floor drain, a laundry tub or a basement toilet when another fixture is used
  • A sewer smell in the house that is strongest near the lowest room
  • Grey or dark water, debris, toilet paper or solids on the basement floor
  • Several fixtures backing up at once, which points to the main line rather than one fixture
  • A backup that begins during or just after heavy rain, when the street system is full
  • Stains and a damp line on the wall base that appear after a sewer event
Our process

How our sewer backup cleanup visit works

  1. Keep people and pets out of the room

    Sewage can carry illness, so the room stays closed off. Children and pets should be kept out until the space has been cleaned and dried.

  2. Stop using every fixture on the line

    Do not run the washer, the dishwasher, the shower or the toilet until the crew has cleared the line. Each use adds more water to the backup.

  3. Remove the water and the solids

    The crew removes the standing sewage with pumps and wet vacuums, and takes out the solids and any soaked debris into sealed bags for disposal.

  4. Clean, disinfect and dry

    Hard surfaces are cleaned and treated, porous materials that were soaked are removed, and the space is dried with air movers and a dehumidifier until the readings reach a dry level.

  5. Clear the line and find the cause

    A sewer line that backs up usually needs to be cleared by a plumber, and the crew's note says where the water entered so that the plumber knows where to look.

Options

Types and options for sewer backup cleanup

Floor drain backup

The water rises through a floor drain in the lowest part of the basement. It is often the first sign that the main line is blocked or that the street system is full. The crew treats the drain area first and then the surrounding floor and wall base.

Fixture backup

A toilet, shower or laundry tub backs up while the rest of the house drains normally. This usually means a blockage in the branch line close to the fixture. The water is still sewage and gets the same cleaning as a floor drain backup.

Main line backup

Several fixtures back up together, and the water shows up in the lowest rooms. This points to the main sewer line or to the street system. The crew cleans the affected rooms and records the level of the water on the wall for whoever clears the line.

Cost

How much does sewer backup cleanup cost in Syracuse?

The cost of a sewer backup cleanup depends on the area affected, the number of materials that must come out, and how many visits the drying takes. The crew prices the job on site after reading the water and the room.

Onondaga County

Why sewer backup cleanup is different in Central New York

A house whose lowest drain sits at or below the level of the street sewer can have water pushed up through that drain when the line is surcharged. The lowest drain is the first point of entry, so the crew checks it first on every call.

Onondaga Creek is channelised through much of the city, and the city says its six-mile section inside the limits is engineered for combined sewage and storm flows. Homes near the creek or near a storm-heavy street can see a backup during a storm even when nothing in the house is blocked.

A backup that affects one house may cross a town line in the surrounding county, where the sewer and the building office are run by a village or a town rather than by the city. The crew asks which system serves the house so the note goes to the right office.

FAQ

Sewer Backup Cleanup FAQs

Is sewage in my basement dangerous?

Yes. Sewage can carry bacteria and viruses, so the room should be kept closed and people should avoid contact with the water until it has been removed and disinfected.

Should I run the pump in the sump basin?

A sump pump moves groundwater, not sewage. If a sump basin is taking in sewage, the pump should be turned off and the crew should be told, since the sewage has to be handled as a separate job.

Does a plumber need to come before the cleanup?

The cleanup and the line repair are separate jobs. The cleanup can start while the plumber is booked, and the crew's note gives the plumber the information needed to find the blockage.

Will my insurance pay for a sewer backup?

That depends on your policy. Many standard policies exclude sewer or drain backup unless a separate endorsement is held, so read the terms and ask the insurer to confirm them in writing.

What if the smell does not go away after cleanup?

A lingering smell often means a wet cavity or porous material that was not removed. Call the crew back so the readings can be checked and the source found.
