Replacing Cast iron sewer pipe

[Chengning Yang]

Does anyone have investor friendly plumbing companies in DFW area for sewer inspection and repair? The house just got foundation repaired, and obviously there’s a leakage at some point. I’ve had a couple of plumbing companies came and quoted me from 30k - 70k to repipe the whole house(2700 sf) which I think it’s insane. I’m also looking for anyone who ever dealt with trenchless sewer relining because it seems like a more affordable way to go. 

It’s a 4bed 3bath single level house with slab foundation.
