I know that building codes vary by jurisdiction so for the purposes of this question I am in Baltimore County, MD.
We have a split joist in our basement. It's a 2x8, about 10 feet long. One side is in a joist hanger, the other side is resting on top of a steel beam. I had a local builder come out and give an estimate which ended up being ~$2500.
Most of what I have seen online suggests using a bottle jack to slowly raise the joist to close the crack, and then sister in another 2x8 (or 2?) to the cracked one, sprinkle generously with glue, and nail them together. I asked the estimator if this was the process that would be used and he said that it was not code and that they would be cutting out and removing the split joist and replacing it altogether. They would also have to pull up carpet in the room above to secure the sheathing.
Am I getting fleeced? Is sistering another 2x8 not code? I want it done correctly but I got a bit of sticker shock at the cost.
Edit: Here's a picture. Center is the crack, left is one end of the joist, right is the other end:
