Wisconsin is a cold-weather install market before anything else. The Northwoods counties bordering the Upper Peninsula — Iron, Vilas, Forest, Ashland, Bayfield — regularly hit -30°F in January and get 180+ inches of annual snowfall. Milwaukee, Madison, and the southeast run warmer but still freeze hard for three months and flip between -10°F nights and 40°F days in the spring freeze-thaw cycle. That daily cycle is actually harder on unsealed outdoor components than the raw cold itself. Our Wisconsin fleet ships a -25°F-rated lithium iron phosphate battery and a freeze-thaw gasket kit on every install statewide as baseline — not a $400 upgrade the way national chains sell it.
Wisconsin housing is dominated by two types. The Milwaukee bungalow and the Polish flat are the single most common urban structure — 1910s–1930s frame or brick two-stories with a narrow 34-inch-wide straight flight off a side entry. These are easy straight rails but the newel post at the bottom is often original oak that cannot be drilled without damaging a century-old detail. Our bottom-mount clamp avoids any newel contact. Madison, Green Bay, Appleton, and the Fox Valley run heavier to 1950s–70s ranchers and split-levels with finished basements — classic straight-rail installs.
The Northwoods and Door County have a completely different housing stock: 1950s–80s cottages and cabins that have become full-time retirement homes, often with steep narrow stairs to a sleeping loft and a separate outdoor entry stair from a walkout basement. Roughly one in five Northwoods installs ends up being an outdoor lift for a cottage porch rather than an interior install, and the seasonal driveway access (some are only plowed in winter by the owner) means we coordinate install timing against weather windows.
Built for the Wisconsin climate
Wisconsin's stairlift enemy is the freeze-thaw cycle, not the raw cold. Every install statewide ships with a -25°F-rated lithium iron phosphate battery as baseline — factory-default sealed lead-acid batteries are rated to -10°F and fail on any January night north of Highway 29. Every outdoor install gets a freeze-thaw gasket kit on the motor housing because a 50-degree daily swing in March pulls moisture into unsealed components and then refreezes it. Northwoods installs (Vilas, Iron, Forest, Oneida, Ashland, Bayfield, Sawyer counties) get an additional ice-dam drip shield because 180 inches of annual snow generates meltwater patterns that destroy unsheltered outdoor electronics. Door County waterfront installs get a freshwater-lake spec similar to what we ship on Lake Champlain in Vermont — Lake Michigan and Lake Superior have enough wind-carried moisture to corrode unprotected rails within three years.
