Grand Haven sits in a cold climate zone with severe winter conditions, and that combination with older housing stock is what drives most of our calls. Steel panels from the 1960s and 70s don't have the thermal breaks or weatherstripping channels that newer doors use, so they flex more in a hard freeze-thaw cycle. Torsion springs lose tension faster in cold metal, which means a spring that was fine in August can snap in January with no warning. Across the roughly 16,400 households we serve, about 8,800 are owner-occupied houses - and a good share of those are exactly the vintage where original hardware is still in place, decades past its rated cycle count. That's not a Grand Haven quirk so much as a Grand Haven pattern: old steel, cold winters, hardware nobody's touched since it was installed.
