Texas is five climate zones that collide inside a single state border. Houston and the Gulf Coast (Galveston, Beaumont, Corpus Christi, Brownsville) sit in the hurricane funnel and run 95°F at 85 percent humidity for six months of the year. San Antonio, Austin, and the I-35 corridor hit 100°F+ on 50 days a year and get thunderstorm-driven golf-ball hail most springs. The Hill Country (Kerrville, Fredericksburg, Boerne) adds extreme temperature swings and hailstorms that wreck unsheltered outdoor components. The Panhandle (Amarillo, Lubbock) gets -5°F winter cold snaps and 70 mph dust-laden straight-line winds. And El Paso sits on a high-desert 3,800 feet with brutal sun UV that cooks plastic seat covers inside two summers.
The Houston metro staircase is the slab-on-grade two-story with a straight 13 to 15 tread flight off the entry foyer. Sugar Land, Katy, Pearland, and The Woodlands all run the same pattern, and the rail fits cleanly. What the Houston install actually requires that national chains miss is a flood-escape seat — homes inside the 500-year flood plain (much of Harris, Fort Bend, and Brazoria counties) got wiped out during Harvey, and any seat motor installed below the base flood elevation has to be removable so the homeowner can carry it upstairs ahead of a storm. We ship a quick-release seat bracket on every install below BFE at no extra charge.
Dallas–Fort Worth and the North Texas metroplex are split between 1980s–2000s suburban two-stories (Plano, Frisco, McKinney, Allen) with easy straight-rail installs and older Dallas and Fort Worth bungalows and Tudors with winding stairs that sometimes need a curved rail. El Paso and San Antonio run heavily toward single-story ranches where the install is often an outdoor porch lift rather than interior. The Hill Country and Central Texas have a distinct mix of 1920s limestone farmhouses and modern luxury tract where the stairs are oversized — 40+ inches wide — and need a wider seat footprint than the standard spec.
Built for the Texas climate
The single worst thing you can do to a stairlift in Texas is leave it factory-default. Our TX fleet ships three standing upgrades on every install as baseline spec: a high-humidity, high-heat lubricant rated to 140°F operating temperature (Houston and Corpus Christi interiors regularly hit that inside a sun-facing stairwell), UV-stabilized seat upholstery rated for 2,000+ hours of direct Texas sun exposure, and a sealed weather hood on every outdoor install to handle Gulf Coast hurricanes and Hill Country hail. Homes inside the FEMA 500-year flood plain in Harris, Fort Bend, Brazoria, Jefferson, and Galveston counties get a quick-release seat bracket standard so the seat motor can be carried upstairs ahead of a storm — that single $45 bracket saved more lifts during Harvey, Imelda, and Beryl than any warranty we've ever paid out. Panhandle installs (Amarillo, Lubbock, Pampa) get a cold-weather battery because the dry-cold -5°F January nights on the Llano Estacado are outside a factory battery's spec.
