Mastic for do-it-yourself, and Aeroseal if you can figure out how to get them to Indianapolis. Aeroseal pumps a sealant into the prepared positive pressure ductwork and seals openings from the inside out. There is several companies in Chicago that do it, and might be a few in Indpls by now.

Yep. Have first hand experience with this, and repairing broken pipes on the cold wet mud floor is not fun.

actually I was really worried about that the first time I went in. It was so bright outside and so dark under there I couldn't see anything for awhile. I was nervous my appendages would be stumps by the time my eyes adjusted
