Fiberglass mimics real wood and resists rot. Steel offers strength at a lower price point, so your choice comes down to budget and style.

Fiberglass Versus Steel At A Glance

Each material brings its own strengths to an entrance:

  • Fiberglass look: These doors echo real wood grain without the rot or upkeep. A grand fiberglass entry door averages about $11,953.
  • Fiberglass return: Beauty meets value at resale. Grand fiberglass entry doors return roughly 87% of their cost.
  • Steel strength: Steel brings toughness and a friendly price. A steel door averages around $2,547.
  • Steel return: Few upgrades pay back like this. Steel entry doors deliver a strong 216% return on investment.
  • Shared perks: Both seal tight against winters. Each option comes in any Sherwin Williams color with custom matching.
