Water intrusion in basement

[Rex Li]

Hey all,

Today I noticed a bit of standing water in the basement of my property, in the laundry area. However, about 10 feet away, not near the laundry, I also noticed some moisture underneath some of the vinyl flooring. You could hear the squish when you press down on it. This leads me to believe it's not related to the washer. I had been out of town for about a week but I know Chicago received some rain over the last few days, so I'm concerned about water intrusion coming from the outside. I noticed the foundation immediately outside the laundry area is showing some deterioration. 

My question is - what are the next steps? Should I just keep an eye on it or contact a professional asap? What type of service/contractor do I need to trace the source?
