Hawaii is the only state in the country where standard mainland stairlift hardware fails before the warranty expires. Windward Oahu (Kailua, Kaneohe), the Hamakua Coast on Hawaii Island, and most of Kauai see salt fog, trade-wind-driven moisture, and year-round humidity above 75%. We have pulled zinc-plated mainland rails off Hilo and Kaaawa homes after 26 to 34 months, corroded through to the drive teeth. Our Hawaii fleet ships every coastal install with 316-grade stainless fasteners, a sealed IP55 motor housing, and a marine-grade powder-coat rail finish — not as add-on line items.
The second factor is Hawaii's housing stock. Plantation-era single-story homes dominate older neighborhoods in Wahiawa, Waipahu, Hilo, and Lahaina — many of them raised 3 to 8 steps above grade on post-and-pier foundations. That is not an interior staircase job; it is an outdoor entry-step lift or a short vertical platform. Newer Oahu subdivisions (Mililani, Kapolei, Ewa Gentry) are two-story tract homes with standard straight flights, and the Diamond Head and Manoa Valley neighborhoods have steep-site homes with 15-to-20-step exterior approaches from the street.
The third factor is inter-island logistics. Hawaii is not a drive-to state. Every Hawaii Island, Maui, Kauai, Molokai, or Lanai install requires barge scheduling for the rail and hardware — typically Young Brothers out of Honolulu — which adds 7 to 12 days to the mainland-arrival window. We build that into every quote upfront so families are not surprised by a 3-week timeline.
Built for the Hawaiian climate
Hawaii's salt-fog and year-round humidity combine to destroy standard mainland stairlift hardware faster than any US climate. A 304-stainless rail — the grade most national chains ship as their 'marine upgrade' — pits within 4 years on windward Oahu. Our Hawaii fleet ships three standing upgrades: 316-grade stainless fasteners on every coastal install (not 304), sealed IP55 motor housings with marine-grade gaskets standard, and a 6-month corrosion follow-up call built into the service plan instead of the standard 12-month. The 6-month check alone catches corrosion early enough to reseal before the gearbox is compromised.
