We don't post panel pricing without seeing the door - section count, insulation, and whether we're matching an existing color all move the number. What we can tell you is what drives the cost on a typical Mount Vernon door: single-panel jobs on common widths run cheaper than matching an odd or older panel size, and insulated sections cost more than single-layer steel. Because the trip from Cedar Rapids is part of every visit here, we try to confirm panel width and door brand by phone or photo first, so we're not making two trips - one to measure, one to install. If the whole door is old enough that panels are hard to source, we'll say so plainly: sometimes a full door replacement costs less than chasing a panel for a model nobody stocks anymore, and we'd rather tell you that up front than sell you a patch that won't match.
