We are fnding Cracks (really expanding this winter) inside the bathroom shower (not a tub but a standup shower with tiles) wall and a corresponding crack on the outside where the bathroom joins the sidewall. The shower is on the second floor. the shower is right on top of the stairs leading to the second floor. The cracking seems like it is shearing off the sidewall. Really appreciate the input. I don't even know who I need to call to take a look. A bathroom remodelor? A home contractor?
Thanks in advance
