An aluminum garage door costs roughly $1,400 to $4,200 installed in the New York area. Aluminum does not rust, which makes it the sensible coastal choice, and it is lighter than steel, which is easier on the opener. It dents more easily than steel, and full-view glass and aluminum doors sit at the top of that range.
Aluminum earns its place in two situations: near salt water, where its immunity to rust is worth real money, and in contemporary full-view doors where an aluminum frame carries glass panels.
Weight is the underrated advantage. An aluminum door is lighter than the equivalent steel one, which means a smaller spring, less strain on the opener and less mass moving over your head. On an older garage where the framing is questionable, that matters.
The trade-off is straightforward: aluminum is softer. It dents from impacts that would leave a mark on steel and nothing more. If the garage is a working space with bikes and equipment moving past the door, that is the deciding factor.
What it is good at
- Does not rust, which is the whole argument on the coast
- Lighter than steel, so less load on the opener and springs
- The only practical frame for a contemporary full-view glass door
- Very low maintenance
What it is bad at
- Dents more easily than steel
- Costs more than steel for the same size
- Full-view glass versions are heavy on price and low on insulation
Aluminum questions
Is aluminum better than steel near the water?
For the panel itself, yes, because it cannot rust. The hardware still can, so a coastal aluminum door should be specified with galvanised or stainless fixings and nylon rollers with sealed bearings.
How much is a full-view glass and aluminum door?
They sit at the top of the aluminum range and beyond it, commonly $3,000 to $6,000 or more installed depending on glass type and size. They also insulate poorly, which matters if the garage is attached to living space.
