Leaking Basement - Baltimore City

[Alex R.]

The Baltimore City rental property that I own is a row home (middle unit) and has never had issues with basement leaks. With the recent rain storms, the unit is now leaking in the basement.

The leaks don't happen in the front of the house or in the back of the house. It's leaking from under the shared party wall in the middle of the house. Is this a roof issue? Has anyone experienced this before? Anyone have an advice on who I should call? HELP!!

99% sure it's one of the following:

• Roof leaking into foundation seeping to the bottom of house
• Downspout overflow or spillage seeping to bottom of house
• Sumppump back up or not working
• Air compressor leak from HVAC unit if central air
• Clogged sewer line (if toilets are having difficulty flushing)
• Water forming a reservoire outside due to unsloped ground (need to have a downslope from house to keep water flowing away from foundation)
• *Next door unit experiencing one of the above
