• Expect to pay $750 -$1,200 to have an average-sized 16x7 foot Steel raise panel garage door installed. The less-expensive models are usually thinner metal and may be single skin; double-skin doors have foam insulation between two panels, giving a nice look both the inside and outside. Premium doors are typically 2 inches thick, filled with insulation, have thicker steel panels and include weather-stripping and weather seals. Steel doesn't rust and doesn't need repainting as often as wood does, but it will dent and repairs can be difficult.
