When I closed [entry] door all green indicators were completely aligned. As we were climbing the door began to make a swoosh sound that; as we continued to climb was getting louder. As I looked at the door I could see light. It was still sterile cockpit but I called the other attendants to let them know of the noise and that now I could see the outside light.My Captain said he was going to call Dispatch (or whoever they call). He did [then called] me back and said we may go back and he would again keep me posted. I continued with my service but then was notified by my Captain that we would be [returning]. When we had returned the Captain came back; checked the door with a flashlight; noted that all green indicators were aligned and that; yes; he could see the outside light. When it was good to open; mechanics were there and noticed both sides of the door were damaged and that [it appeared to have] been like this for some time. I assured the Captain that I hadn't slammed the door and he agreed that it was closed correctly. In the meantime he mentioned to me that while they were talking about how to handle this issue... The ACARS message sent to him was to have the Flight Attendant wet some napkins; put her finger in the hole; and plug it up. He commented that they did not want to have him return but he demanded; due to the safety of the plane; it needed to come back. My Captain handled the situation so professionally and the passengers were very thankful for the decision that was made. It was a calm turn around.
A CRJ-100 returned to its departure airport for maintenance when the Flight Attendant reporter note a 'swooshing' sound from the passenger entry door and then noted outside light visible around it.
