Hemlock is a small pocket compared to the rest of the coverage area - about 515 households, against roughly 18,597 across the whole service territory. That's a tight, mostly single-family stretch of homes, and the median household income here runs higher too, at $92,031, well above the $78,155 median for the broader area. Higher income and an older build year together usually mean one of two things: either the door's been upgraded at some point to a heavier insulated panel, or it's the original door and it's been well kept but is due. We see both. Either way, this part of the region sits in a climate zone rated cold and severe, which matters more for door material and weatherstripping than it does for the opener itself. Steel expands and contracts here, and old wood-composite panels from that era don't hold up the way steel does over fifty-plus winters.
