Kennewick sits in a cold-moderate climate band, which means the service area gets real winter cold snaps without the deep-freeze extremes that drive manufacturers to spec heavier insulation as standard. A lot of the doors that went in across the six main neighborhood pockets here during the 1981-2000 building boom were specced to that era's lighter standard - single-layer steel or minimal foam core - because that's what the climate and code called for at the time.
Thirty-plus years later, that's the door losing its seal integrity right when winter cold makes the steel contract and the weatherstrip stiffen. It's not a defect, it's just a door built to a 1980s spec meeting 2020s weather swings on the same hardware.
We size new installs to handle that cycle - thicker panel cores, better bottom seal retention - rather than matching the original spec just because it matches the house. On a $87,022 median household income area like this one, most owners we talk to want the door to outlast the mortgage, not just match what builder put in originally.
