Since I specialize in both steel doors and fiberglass doors, I often get asked the same question when a new project begins: “Which one is better?”
The truth is, it depends on what the client needs—and what kind of space we’re designing for.
The Overlooked Option: Smooth Finish Fiberglass
Most people are familiar with woodgrain fiberglass doors—they’re a go-to for clients who want the warmth of a wood look without the upkeep of real wood. But one thing I’ve realized over the years is that many homeowners don’t even know that smooth finish fiberglass doors exist.
And honestly? They’re one of my favorite choices for solid doors in high-traffic areas.
Why? Because while steel doors are definitely reliable and cost-effective, fiberglass doesn’t dent. And that makes a huge difference over the lifespan of the door.
Steel vs. Smooth Fiberglass: Durability Over Time
To be clear, your brand-new steel door isn’t going to dent easily. But think long-term. After 20+ years of wear and tear, a steel door is more likely to show cosmetic damage—especially if it’s in a busy area like a side entry or a frequently used mudroom door.
In contrast, a smooth fiberglass door holds its shape and surface far better over time. Yes, it might cost an extra $500 upfront—but if this is a door you’re planning to keep for the long haul, the investment makes a lot of sense.
It doesn’t even look that different from a steel door. But in terms of long-term value and low-maintenance durability, I’d say it often comes out ahead.
Should You Make the Switch?
Of course, if you’re planning to replace your door again in 5–10 years, it might not matter. But the whole point of investing in a good quality entry system is to avoid doing this all over again every few years. A well-built, properly installed fiberglass door should last decades—with minimal upkeep.
That’s why, especially on solid doors in busy areas, smooth finish fiberglass is often my recommendation—even if it’s not the flashiest choice.
