Steel Doors
Affordable and strong, steel doors are a common pick for security. Keep scratches painted to prevent rust, especially in coastal climates.
Fiberglass Doors
Fiberglass resists dents, warping and moisture and can be finished to look like wood grain. It suits most climates, including humid and coastal areas.
Wood Doors
Solid wood delivers a classic look and weight. It needs a protective overhang or porch in harsh climates and periodic refinishing to prevent weather damage.
