His closest opponents were Jan Quillman and Warren Dorris.
About 15,000 votes were cast, and the former firefighter, longtime local barber and long-serving city councilman won by slightly more than 1,000 votes.
Tom Giarrante had the endorsement of nearly every major union with a presence in Joliet. He won in a nine-way race thanks in part to a pledge to cut city services only as a last resort. That's despite the city's 27-million dollar budget deficit.
"Joliet is facing a tremendous shortfall, but Joliet knows how to survive tough times," said Giarrante.
Joliet, the state's fourth largest city, is facing the same problems plaguing many municipalities. For years, casino revenue has eased the taxpayer burden, but, like other tax revenue, it has declined, leading some to question whether Joliet can continue to subsidize amenities like a ballpark, the Rialto Theater, and a local water park.
The retirement of Art Schultz, Joliet's mayor for the last 20 years, now leaves those tough choices in the hands of his longtime ally on the city council, Tom Giarrante.
"Some of the opponents were talking about selling this or selling that, abd I said: 'How am I going to go out and sell the city of Joliet when those people come here and see for sale signs on these great amenities?'" said Giarrante. "As for the budget, yes, it's almost 10 percent of our budget is shortfall - it's going to take all of us, everything is on the table."
Despite having weathered a tough nine-way race, Giarrante says the real work lies ahead of him.
Voter turnout in the Joliet mayor's race was about 19 percent.

A recent tax hike prompted concerns from residents and the candidates.
Councilwomen Teri Olian and Nancy Rotering worked together on the city council.
"It was so close, we worked really hard, and we walked every precinct," said Rotering. "We rang thousands of doorbells, we made thousands of phone calls, and our work paid off, and I'm really pleased."
"I'm very proud of our community for all of the support that they gave me, and we have a wonderful, wonderful place here, and I'm proud to live here," said Olian.
In Schaumburg, for the first time since 1995, longtime incumbent Al Larson faced a challenger. Brian Costin, 31, ran on an anti-tax platform.
Larson says a drop in sales tax revenue made the property tax necessary, and Tuesday night, Larson declared victory.
Larson said he won because of "residents of Schaumburg who feel as though the leadership that myself and my fellow board members have provided for the last 37 years has led Schaumburg in a great direction to become one of the premier communities in the northwest suburbs."
In Naperville, 16-year incumbent George Pradel faced two challengers, Doug Krause and Kenn Miller. Pradel won by a large margin.
