We carry standard torsion springs sized for single and double steel doors, the sizing that matches most of what's on Hiawatha's 1990s-era housing stock, plus the cables, rollers, and drums that go with them. Median household income in Hiawatha runs around $67,628, noticeably under the $95,000 median across the broader service area, and that's part of why the truck stocks mid-grade steel hardware as the default rather than premium or custom-width parts - most jobs here are standard sizes, not special orders. What we don't carry on the truck is anything custom-width, insulated glass-panel sections, or openers outside the common chain and belt-drive models - those get special-ordered, and if that's what you need, we'll say so up front rather than stall you waiting on a part that isn't coming today.
