There has been water gushing through an old boiler exhaust opening (although has been there for over 20 years and this only started happening in last few months) and water leaking through walls. The garden level apartment changed their pavers few months ago so we do not know if it's because of the drainage system that was placed OR if there is a clocked drainage line somewhere or crack in drainage pipe.

Vicinity of in New York
We have a large crack in the wall on our basement level that feeds all the way to the neighboring buildings foundation. Water leaks through the crack, especially during heavy rainfall, and there is constantly standing water on the floor. We have several sub pumps in our building due to an active body of water than runs underneath the building, so the water is not surprising, but needs to be dealt with. Hoping for someone to come out to diagnose issue and provide us with an estimate for repair. Thank you - Billy
