If the broken sewer pipe was caused by some natural disaster then the broken sewer pipe might be covered by homeowners insurance.
But if the broken sewer pipe resulted from something else such as a root going into the sewer pipe then homeowners insurance will not cover the cost of the broken sewer pipe.
If you have a broken sewer pipe that needs to be dug up and replaced then you'll have to cover the cost of the broken sewer pipe out of your own pocket.
If you can get a handyman to do the job the cost of the sewer pipe is usually around $100.00 to $200.00 and then the cost of the labor which might run another $100.00 to $200.00
If you hire a pro plumber to replace the broken sewer pipe then it might cost you $800.00 to $3,000.00 depending on how much sewer pipe needs replaced and how deep the sewer pipe is.
