Choosing Fiberglass vs Steel Front Doors

If you live in a coastal area with high humidity, fiberglass might be a better bet due to its resistance to moisture and temperature stability. If you’re on a budget, a steel door might be a more cost-effective choice initially. But often, a fiberglass door is cheaper in the long term. A steel door may be the better option if security is your priority. If you prefer the look of natural wood or a more customizable appearance, then a fiberglass door gives you more options.
