Hi Chicagoland BP community! 

Looking for some referrals for contractors who could come and check a finished basement that had minor flooding after the recent storm in Chicago (Avondale). I didn't get a lot of water and it was all manageable by the tenants, but given this happened I want to try to understand the reason and where to look (e.g., do I need to install a new/ better sump pump). 

Few companies I got from google search offer free estimates (e.g., US waterproofing, Everdry waterproofing) but they are all swamped with work and I can't get an appointment until mid-June.

Any leads will be highly appreciated!
