Sewer line repair

[Maroof Mohammed Farooq]

Hi BP community,

We recently had a sewer inspection on a property that we are under contact near Denver. The sewer inspector found two issues:

1. Small offset at 60 feet.

2. Large offset at 22 to 24 feet. They do recommend replacing cast iron pipe to clay for this portion.

I am looking for your input based on experience on the following items:

1. Is the process of fixing this quite involved ? 
2. Will fixing small parts of sewer line be a good long term solution ? Or do you recommend I budget for a full sewer line replacement in the near term ? 

If you have had a similar experience, I would love to know what your approach was and whether you would recommend it.
