Is There "job Abandonment" For Contractors In Indiana? Warranty Work On New Build.

Location: Indiana. Not sure if I'm in the right sub, but here goes. In Jan 2025 we closed on a new build ~15 minutes outside Indy. The home came with a warranty, and anytime we needed work done, the builder sent contractors in to fix whatever.

As we neared the 10-month mark our warranty manager began talking to us about marking places in the home where we've had nail-pops, corner splits, etc. Things that happen as homes settle. They would come in and fix/repaint those areas. I'm not lying when I say he told us to mark everything we saw. So that's what we did. We were already at 15 months when the contractor came...and did half the work. Two weeks later, another tech from the same contractor came back to do more. He re-mudded and partially sanded one wall, and touched up a few other minor spots. He left without painting any of it, or working on the main hallway wall, which is the one of the bigger issues (it, too, needs re-mudded/sanded at the seams and has a wave in it along the baseboard). That was two weeks ago. No tools were left behind; he was in and out same day.

There's been no response to follow-up emails, and no one returns calls. At what point in Indiana can we assume the builder and contractor aren't going to finish the work? We'd like to paint in the house, but doing that means the builder will no longer be responsible for any defects on walls we paint (there's verbiage to this effect in the warranty).

We feel like we can't make this place our own, and are to the point where we'd like to hire our own contractor, have them finish the work, then sue the builder for the cost. Pipe dream?
