How Long Do Exterior Doors Typically Last?
Fiberglass doors, often with an insulated core, are known for long-term durability. Many last 30 years or more with minimal maintenance. Fiber cement siding often gets attention for durability, but fiberglass doors offer similar resistance to weather exposure. Fiber cement products are engineered to handle moisture and temperature swings, and fiberglass performs in a similar way. Unlike solid wood, fiberglass does not absorb moisture easily, which helps prevent moisture damage and mold growth. Homeowners committed to low upkeep often choose fiberglass because it handles environmental factors like heat, cold, and heavy rain without breaking down.
