A single cracked or dented panel on a 1988-era door isn't just cosmetic. The polystyrene core in doors of that generation was never a vapor barrier, and in this part of Tennessee the swing between summer humidity and a cold snap works moisture into a compromised panel faster than people expect. Once that happens, the panel warps slightly, which throws off the roller alignment on that section and puts uneven load on the track. Median household income across this service area runs $92,292, but here in Rural Hill it's closer to $84,310, and that gap matters for the fix: we price a steel-skin panel replacement to match the original door first, rather than steering straight to an aluminum or wood composite upgrade that costs more and doesn't address the actual failure.
