Replacing a garage door entirely - rather than repairing the existing one - usually makes sense when the door is more than 15-20 years old, has significant structural damage, or you’re upgrading for insulation and curb appeal.
Choosing a door
Material. Steel is the most common choice for durability and price; wood offers a premium look but needs more maintenance; aluminum and fiberglass resist rust well in humid or coastal climates.
Insulation. Insulated doors (look for an R-value rating) matter most if the garage is attached to living space or used as a workspace.
Style. Carriage-house, raised-panel, and full-view (glass) styles are the most common, and many manufacturers offer custom color and window options.
What installation involves
A typical single-door installation takes 4-6 hours; a double door or one requiring track/frame modifications can take longer. Installers will remove the old door, inspect and often replace the tracks and springs to match the new door’s weight, then install and balance the new door and opener connection.
Getting quotes
Because door and opener combinations vary so much in price, it’s worth getting quotes from a couple of local installers - most offer free in-home estimates and can advise on the best style and insulation level for your climate.
