What I found on a South Side installation last winter
Every new installation in Milwaukee starts with a measurement, and that measurement always tells a story.
I was out on a job on the South Side last January. The homeowner wanted a new insulated double-car door. He had the original single-layer steel door since the house was built in 1983. No insulation, no bottom seal. The garage in winter matched the outdoor air.
The measurements turned up two things we would have hit on installation day otherwise. The existing door was 16 feet wide but the rough opening was 15 feet 10 inches, not unusual in older construction, so the new door needed a specific panel configuration. And the spring hardware had been mounted too close to the wall, cutting into the backroom the new opener arm needed.
We relocated the spring anchor plate, corrected the order for the actual width, and installed a two-layer insulated steel sectional door with a polystyrene core, rated R-9, that same day. R-value is the number that measures how well insulation resists heat transfer. Going from zero to R-9 in a Milwaukee winter is a real difference. He uses the garage as a woodworking shop and called back in March to say he had run his space heater once that whole month.
Door weight and spring load were recalculated once the new door's specs were confirmed. Everything balanced clean on the first test cycle. One site visit. One installation day. Done right.
