Bowing wall who to call how to fix

I have a 1955 year old row home two-story 2 bed 1 bath cement basement. The back wall is bowing and protruding away from the house the windows are shifted back bedroom and kitchen and dining room. I keep having the same leak in the roof in the back bedroom nomatter how many times we patch it and fix it it seems as though the water must be coming from the wall outside. I need new windows I can't put new windows in a wall that's moved so I need to fix the wall first. I'm going to try to send you some pictures. Second problem the house next door just sold was bought rehabbed pretty much from the ground up entire house replaced everything made it a three bedroom two bath it sold for a considerable amount of money. What I noticed that they did to the back wall was took it down to the brick cement the entire back wall I don't know if they pointed it or if they're problem was the same as mine then they reframed sheetrock and put a brand new kitchen in. They put brand new windows throughout the whole house out on the back end they recapped them deeper than a normal standard window and I don't know if they were trying to hide the shape or if that was what they wound up with in the end after fixing the problem. It looks good it looks way better than mine. What I do know about the house next door is that the original owner had a sub pump in the basement I don't know what her water source where her water source came from she just had a sub pump when they redid the house they made the third bedroom the basement put a brand new bathroom in central air all the wiring for everything it's all brand new and they tiled the basement floor sub pump is gone. About 3 weeks ago I started to get surfacing water coming up from my concrete floor in basement. I have been here 17 years never had water in my basement.
