Hi this tub and surround and only a few months old. It is a three peice surround with a lip on the tub and contractor said it did not require caulk. I used a quick dry poly caulk that ended up peeling away quickly. I pulled it off and now found this water damage. It is on both sides of tub in this location. The contractor that did this is a small town guy. I highly doubt he will come back to fix. Can anyone tell me if this is because the area between the tub and surround is just leaking water out during each shower? Should i just re caulk? Please help.
