With 8,331 households and a median income of $120,685, Murrysville sits well above the service area's overall median of $62,874, and that shows in the doors too - more insulated steel doors, more belt-drive openers, fewer of the bare single-skin panels you find on the oldest housing stock. The area still sits in the same cold-climate band as the rest of the region, so winter is still the stress test: a steel door with worn weatherstripping or a spring that's lost tension in the cold will show it fast, same as anywhere else here. The difference in Murrysville isn't the weather - it's that the hardware underneath is newer, so when something fails, it's more often a part that wore out than a part that was never built to meet modern spring cycle counts to begin with.
