The best material is fiberglass. If you choose the right door brands, fiberglass doors are absolutely beautiful but don’t have the drawbacks of wood or steel.
The biggest problem with wood doors is they lack durability. It’s no accident that wood doors come with extremely short warranties, and these warranties are loaded with exclusions. We no longer install wood doors because we don’t feel like we can stand behind them.
Steel doors also have issues. They dent easily, and in our opinion, they are not as attractive as fiberglass or wood.
Fiberglass has it all. Durability, beauty, and security.
