Cast iron sewer replacement under slab

[Chad Alan Riggs]

I need to replace about 50 feet of cast iron pipe under a slab house. I was quoted about 23k. Does anybody know a company that can do it cheaper? I feel 23k is a bit too high.

While the cost will be somewhat area dependent, any work under a slab is going to be expensive.  We had a flip on a slab that we wanted to move the washer location and was quoted $7,500 for that alone.  Recently, a friend of ours had to have cast iron pipe replaced here in PA outside of the house and received quotes ranging from $2,550 to $12,000.  As far as your quote, I would get at least 1 or 2 more quotes and see what you find locally as it may be your area or the company you called with the high estimate.  Either way, digging under a slab is not going to be a cheap repair.

Thanks, I will get more quotes.

Aloha,

Have multiple sources advised the line must be replaced, vs. installation of a liner system?
