Boot was very moldy Erin D. • Lombard, IL • December 05, 2014 My Repair & Advice I purchased a new door boot to replace an old one that had gotten very moldy. The replacement took me about an hour to do by myself. The hardest part was putting the spring on. I used clamps in addition to the spacers. That helped immensely! All in all, not a bad DIY repair.
