Most homeowners are surprised to learn that almost all homeowners’ policies include exclusions for damage caused by sewage water originating outside their home. For example, if your city or county’s sewer main line backs up because of tree roots or debris and the sewage water backs up into your home, the resulting damage will not be covered, or if it is, may be subject to significant limits—often covering only $5,000 or $10,000 of damage. Given the scope of cleaning required in these events, this amount will likely not cover even the costs to clean up the sewage. What’s more, some policies even exclude backups on the homeowner’s own lateral lines. Insurers may offer policy endorsements for coverage at an additional cost, but as many homeowners shop based on price alone, they may not realize they lack the coverage until it is too late.
