What is the cheapest option for a garage door?

The cheapest garage door option is a non-insulated single-skin steel sectional door, which runs 400 to 900 dollars for a single-car size and 700 to 1,500 dollars for a 16-foot double, before installation. Builder-grade lines like the Clopay 4040, Amarr Stratford 1000, Wayne Dalton 8000, and CHI 2240 fall in this range. Installed cost is typically 800 to 1,800 dollars total. Tilt-up one-piece steel doors are slightly cheaper but rarely used in new construction because they need extra clearance. The very cheapest option is a basic roll-up steel door from Home Depot or Menards, sometimes available under 600 dollars without installation. Skipping insulation and windows saves the most money, though it costs you in noise, durability, and energy efficiency.
