Lake Wissota, Wisconsin

Wisconsin adopts the 2010 ADA Standards. For automatic door operators you need activation force ≤ 15 lbf for interior doors, and the door must have a closing delay (minimum 3 seconds) per ANSI A156.19. Your sensors must activate within 12 inches of the door. We've retrofitted storefronts in Lake Wissota Estates and medical offices near HSHS St. Joseph's—often you need a low-energy swing operator, not a full automatic sliding system. We'll check your current setup against the standard.

Hard. On a -10°F morning your LCN closer's hydraulic fluid thickens—latch and sweep speeds drift, and the door might not close fully. By February the EPDM threshold seals have taken two months of compression; they don't rebound after thaw. Then ice builds in the gaps, and an aluminum threshold expands against the frame—you get binding or cracked fasteners. We replace seals every 2–3 years in this climate and adjust closer sweep speeds before the first freeze, usually by October 15.

Dock doors in food distribution or warehouse settings here see 30,000+ cycles a year. We recommend a full inspection every 6 months: check spring tension (torsion springs typically last 15,000–25,000 cycles), look for worn cables or misaligned tracks, and test safety features on automatic operators. For storefront entry doors in retail or municipal traffic, once a year is enough unless you notice dragging or noise. We track maintenance schedules by building, not calendar.

If the frame is rusted through at the base or the door skin has delaminated from freeze damage, you're replacing. Same if you need a higher fire rating (say changing from a 90-minute to a 3-hour door) for a compliance upgrade—you can't retrofit that. But if it's a worn closer, broken spring, or misaligned track—that's a repair. We've pulled 2-hour fire doors with UL labels intact that just needed new hinges and an adjustment. We'll measure the gaps (more than 1/8 inch in a fire assembly means replacement) and cycle-test the operator before deciding.
