My wife and I just bought our first house. It's a 95 year old Colonial twin that was a total rehab. We just learned yesterday that our soil stack is leaking from the second floor bathroom (the only bathroom in the house) into the basement. There's quite a bit of water after a shower or flushing the toilet.
The pipe runs from the basement, behind some kitchen counters and wall, up to the second floor bath. We had a bunch of plumbers round today to give some estimates. Most were around $2,000. The lowest one - who happened to be the guys who spent the most time at the house and were the most pleasant to deal with, overall - brought their carpenter out to take a look. They seemed to think the best option is to open the outside wall. They want to remove some of the vinyl siding and what's underneath that to get to the pipe. Pipe replacement is $1,200 and the carpentry/siding work is $600. Does that seem reasonable?
I was a tiny bit concerned about the outside wall option since one of the other plumbers made a big stink about I shouldn't let anyone do something like that and that it could really mess up my house.
Any advice would be greatly appreciated!
