$8400 to replce all the cast sewer pipe im my crawl space and boot the connection outside of my foundation wall (which will require some outside digging)

I have about 25ft of cast pipe for the main sewer sections, plus connections to: 2 baths; my 2 inch cast laundry room pipe; and the kitchen. They will replace the cast to the toilet in the main math but keep the copper drains in the 2nd bath. They also will replace the vent pipe to the roof.

They said it would take almost 5 days (4 to 5) to do the work. For two guys (one master plumber and another), that would be $200/hr to pay the 2 workers
