Milltown, Wisconsin

If your building is open to the public — retail, medical, municipal — yes. Wisconsin follows ADA Standards, with specific force and timing specs: automatic doors must open in 1.5 to 3 seconds and close at a latch speed no faster than 1.5 seconds. That's not just an adjustment; it's traceable to the operator settings. We check that on every service call because a violation during an inspection can mean a citation.

Most closers you find on Milltown buildings are rated for -20°F. When we hit -10°F — and we do — the hydraulic fluid thickens, slowing the sweep speed and often freezing the latch check. Thresholds: EPDM seals lose compression after repeated freeze-thaw cycles; you'll see a 1/8-inch gap that leaks air and snow. Aluminum thresholds also contract enough in deep cold to pull away from the framing. We've swapped dozens in Milltown alone.

For dock doors running 20+ cycles a day — like at a warehouse near Milltown's industrial park — schedule maintenance every 6 months. Storefront entry doors with automatic operators: every 3 months for safety sensor checks and lubricant wipe-down. Torsion springs on high-cycle doors should be replaced at 15,000 cycles, not when they snap. We tag the door with the cycle count after each service so you know exactly where you're at.

Three signs: frame damage (bowed or cracked in the hinge area — can't be patched to hold fire-rating), cycle count over 25,000 on a steel dock door where the panels are warped, or a 3-hour fire door that's missing UL labels or has gaps beyond 1/8 inch around the perimeter. Repairs on doors that worn past these points won't pass inspection. You'll spend more on repeated fixes than a replacement. We'll tell you straight up.
