Hudson, Wisconsin

ADA compliance for automatic doors in Wisconsin follows federal standards enforced through state building codes: clear opening width must be at least 32 inches with a 90-degree stop. Automatic operators must reduce opening force to 5 pounds or less. The door must stay open for a minimum of 3 seconds. Sensor zones should detect a person within 3 feet. We check these specs with a digital force gauge and timer on every automatic door service call in Hudson.

Most LCN and Norton closers use fluid rated to -10°F. Hudson gets colder. That causes closers to skip sweep, latch too hard, or fail entirely. EPDM threshold seals lose compression after repeated freeze-thaw cycles — you’ll feel a draft at the bottom. Aluminum thresholds expand and contract, creating gaps that let in snow and cold. We adjust closer speed settings for winter — slower latch speed, sweep speed under 90° — and recommend seasonal seal replacement every 2–3 years in Wisconsin.

Dock doors in Hudson warehouses that cycle 20+ times daily need inspection every 6 months or 10,000 cycles — whichever comes first. Storefront automatic doors in retail blocks on Vine Street should be serviced annually. We check spring tension with a torsion spring gauge, lubricate hinges with dry PTFE spray (never WD-40), and test closer force and latch throw. Following this schedule prevents most emergency failures and keeps doors within warranty requirements.

Replace when the frame is rotted or rusted beyond repair — typical after years of ice dam formation on thresholds. Replace when door cycles exceed the spring rating: standard torsion springs last 10,000 to 25,000 cycles. Replace fire-rated doors if the UL label is missing or the door edge gap exceeds 1/8 inch per NFPA 80. If repair costs come close to 50% of a new door’s price, replacement is the better call. We always show you the numbers before we start.
