Standard homeowners insurance does not cover damage or cleanup from sewage backups or overflowing drains. To get coverage, you must explicitly add specific endorsements or standalone policies to your insurance.
Standard homeowners insurance may only cover sewer line damage caused by sudden, accidental perils such as fire, explosion, or impact. Gradual wear, root intrusion, corrosion, or poor maintenance are typically excluded from standard policies.
Topics to Avoid When Speaking to a Home Insurance Adjuster
Generally speaking, you're usually responsible for drains inside the boundaries of your property, while the sewerage company is responsible for lateral drains, which are usually outside of property boundaries, and sewers. Although most sewers are now publicly owned, there are still some private or unadopted sewers.
Damage caused by most disasters is covered but there are exceptions. Standard homeowners policies do not cover flooding, earthquakes or poor maintenance. Flood coverage is provided by the federal government's National Flood Insurance Program, although it is purchased from an insurance agent.
Allstate denied the most claims according to a Weiss Ratings study of 2024 data, with 50.9% of claims closed without payment by Allstate Vehicle & Property Insurance Co. and Allstate Insurance Co. at 49.8%. It was followed closely by USAA at 49.5%.
The 80% rule in homeowners insurance dictates that your dwelling coverage must equal at least 80% of your home’s total replacement cost. Meeting this threshold ensures your insurance company covers the full cost of repairs (minus your deductible) for a covered loss.
A sewer line that is breaking shows 4 early warning signs. Common signs include sewer gas odors near drains, repeated clogs and backups, mold or damp spots inside, and unusually lush or soggy areas in the yard along the pipe route.
"Sewage poisoning" refers to health complications caused by inhaling toxic sewer gases (like hydrogen sulfide and ammonia) or ingesting water/food contaminated with raw sewage. Symptoms range from mild gastrointestinal distress to severe nervous system issues.
Sewer lines generally last between 50 and 100 years, largely depending on the pipe material and environmental factors. Older homes with aging infrastructure may require repairs sooner.
One hidden truth is that insurance companies often aim to minimize their payouts. Adjusters may downplay the extent of the damage, offer lowball settlements, or employ various tactics to delay the claim settlement process.
Common Reasons for Claim Denials
Document Your Losses
Insurance claims are won and lost based on evidence. Keep records of your medical bills, your out-of-pocket losses and your lost wages. The more proof you have of your losses, the more likely you are to outsmart the insurance company's attempt to deny or lowball your claim.
Common Sewer Line Problems
When a pipe bursts under your house, gallons of pressurized water can flood your crawlspace or slab foundation. This rapid water release causes severe structural damage, ruins flooring and subflooring, and creates a prime environment for toxic mold to grow. It will also cause a drastic, unexplained spike in your water bill.
Essentially, a toilet overflow is a localized clog within the toilet itself, while a sewer backup is a blockage further down the plumbing system impacting multiple drains. Clog and overflow water events are often mischaracterized as sewage backup by unwitting property insurance consumers or untrained technicians.
Yes, sewer gas contains toxic elements like hydrogen sulfide and ammonia, and prolonged exposure can make you sick. Mild exposure causes headaches, dizziness, and nausea. In rare, severe concentrations, it displaces oxygen and can be fatal.
Common Signs of a Broken Sewer Line
The incubation period for a fecal-oral disease (i.e., the time between initial contact with contamination and onset of illness) is usually one to three days.
To clear a main sewer line clog, use an industrial-strength chemical main line opener (like Green Gobbler Main Line Opener or Instant Power Main Line Cleaner), or physically clear the blockage using a motorized drain auger (sewer snake). For severe blockages or tree roots, an auger is the most effective solution.
Without an endorsement, your insurer may still help cover the cost of the repairs, up to your policy's limits, if the line is located on your property and the damage occurs sudden and accidentally. A standard homeowners policy may also pay to repair the actual sewer line if a covered peril caused the damage.
In plumbing, the "135-degree rule" is a code standard that dictates how much a horizontal drain pipe can bend or change direction. It limits the total cumulative angle of pipe fittings before a system requires an access point (cleanout) or must be vented, ensuring proper flow and preventing chronic clogs.
Dave Ramsey considers homeowners insurance a non-negotiable tool to protect your biggest asset. He emphasizes carrying enough coverage to completely rebuild your home and replacing all your belongings in the event of a total loss.
Certain dog breeds are frequently excluded from standard homeowners and renters insurance policies because they are considered high-risk for liability claims. The average cost of a dog bite claim is now nearly $70,000, driving insurers to restrict coverage to mitigate financial exposure.
