The short answer

What Standard Policies Usually Exclude

A typical homeowners policy may cover sudden water damage from a burst pipe or rain, but sewer backup is often a separate exclusion. Water that backs up from the sewer line into your home is considered a different risk. Insurers treat it that way because it can involve contamination and extensive cleanup.

Your policy's declarations page and endorsements will show whether sewer backup is included. Look for terms like 'sewer backup' or 'water backup' in the exclusions section. If it is not listed, assume it is not covered unless you add it.

How to Add Sewer Backup Coverage

You can often add sewer backup coverage as an endorsement to your existing home policy. This rider usually costs a modest amount and raises your coverage limit for this specific peril. It may also cover the cost of cleaning and sanitizing affected areas.

Contact your insurance company to ask about adding this coverage. The cost depends on your home's location, the age of your plumbing, and your coverage limits. Policies vary, and your insurer decides what is covered.

  • Check your policy for the words 'sewer backup' or 'water backup'
  • Ask your insurance company about adding an endorsement
  • Know your coverage limit before a loss occurs
  • Keep a record of your policy number and insurer's contact
  • Consider a plumber's inspection of your sewer line

What to Do Right After a Sewer Backup

If sewer water enters your home, act quickly to protect your health and property. Avoid contact with the water because it may contain bacteria and viruses. Turn off the water supply to your home if you can do so safely, and keep children and pets away from the affected area.

Document the damage with photos and a written list of affected items. Contact your insurance company as soon as possible to report the incident. Do not throw away damaged items until the adjuster has seen them, unless they pose a health hazard.

When Sewer Backup Might Be Covered

Some policies automatically include sewer backup coverage, especially in areas with heavy rainfall. Check your policy's endorsements section to see if it is already there. If you have a separate rider, it typically covers the cost to clean up and repair damage caused by water that backs up through drains or the sewer line.

However, coverage can be limited. Some endorsements have a lower limit than your main dwelling coverage. If the backup is caused by a blocked pipe on your property, the insurance company may treat it differently than a municipal sewer overflow. Read your policy carefully and ask questions.

  • Look for a separate sewer backup endorsement on your policy
  • Understand that coverage limits may be lower than your home coverage
  • Ask if a blocked pipe on your property is covered
  • Know if your policy covers the cost of cleaning contaminated items
  • Check if your policy covers the cost of a plumber's repair to your sewer line

How to Reduce Your Risk of Sewer Backup

Prevention is often easier than cleanup. Have a plumber inspect your sewer line for tree root intrusion, cracks, or blockages. Keep your gutters and downspouts clear so stormwater flows away from your foundation. In humid subtropical climates, heavy rain and spring thunderstorms are a real possibility.

Install a backwater valve on your main sewer line if your community allows it. This valve closes when water backs up, protecting your home. Also, avoid flushing items like wipes or grease that can clog your pipes. Keep your shutoff valve location written down.

Frequently asked questions

Does renters insurance cover sewer backup?

Renters insurance may cover your personal property if sewer backup is included in your policy. It typically does not cover damage to the building itself. Check your policy or ask your insurance company about adding a sewer backup endorsement to your renters policy.

What if the sewer backup is caused by the city's sewer system?

If the backup comes from the municipal sewer system, the city may be responsible. You can file a claim with the city, but you still need to report the loss to your insurance company. Your policy may cover the damage and then seek reimbursement from the city. Check your policy for details.

How long do I have to file a sewer backup claim?

Most insurance policies require you to report a loss promptly. Waiting too long can delay your claim or cause it to be denied. Contact your insurance company within a few days of the incident. Take photos and keep receipts for any emergency repairs you make.
