Best Garage Door Materials: Steel, Wood, Aluminum & Fiberglass Compared
Choosing the right garage door material is one of the most important decisions when installing a new garage door in the Pacific Northwest. Seattle’s wet climate, temperature swings, and salty air (for coastal homes) all affect how different materials hold up over time.
Steel Garage Doors
Best for: Most homeowners in Redmond, Bellevue, and Seattle metro
Cost: $600–$2,500
Lifespan: 20–30 years
Steel is by far the most popular choice. It’s durable, low-maintenance, and available in dozens of styles. Modern steel doors come with polyurethane foam insulation (R-16 or higher) which is ideal for the Pacific Northwest’s cool, damp winters. The main drawback: steel can dent from impacts and may rust if the finish is scratched.
Wood Garage Doors
Best for: Historic homes, high-end properties
Cost: $1,200–$4,000+
Lifespan: 15–25 years with proper maintenance
Wood offers unmatched beauty and curb appeal, but it requires more maintenance in Seattle’s wet climate. Expect to repaint or re-stain every 2–4 years to prevent warping and rot. Cedar and redwood are the best wood choices for the Pacific Northwest due to their natural moisture resistance.
Aluminum Garage Doors
Best for: Modern homes, coastal areas
Cost: $700–$2,000
Lifespan: 20–25 years
Aluminum is lightweight, rust-resistant, and ideal for coastal Puget Sound homes where salt air is a concern. It’s less insulating than steel and can dent easily, but its corrosion resistance makes it a smart choice for areas near water.
Fiberglass Garage Doors
Best for: Coastal exposure, modern aesthetics
Cost: $1,000–$2,500
Lifespan: 15–20 years
Fiberglass resists moisture and salt air better than most materials. It can mimic the look of wood without the maintenance. The downside: it can crack in extremely cold temperatures and offers limited insulation unless filled with foam.
Our Recommendation for Seattle Homes
For most homeowners in the Greater Seattle area, we recommend insulated steel doors as the best all-around value. They handle the Pacific Northwest climate well, offer excellent energy efficiency, and require minimal maintenance.
