After the main was shutoff before my trip, I saw water emerged around the right side counter of the sink, near my dish washer. I turned on the faucet and let the water ran out, and wiped the counter around the sink dry. After my 12 day trip, I found the cabinet doors under the sink have black color mold around the lower edges and sides near the dish washer.
Is this possibly a plumbing problem between my sink and the dish washer? Who should I get to look into this? A plumbr and mold remediation company? Why did this happen?
