Fiberglass doors are often marketed as the low-maintenance, budget-friendly alternative to wood. While they do have their place, many ads gloss over their shortcomings—and overlook what solid wood doors still do better. At Nick’s Building Supply, we’ve worked with thousands of homeowners who discovered that a well-crafted wood door offers benefits fiberglass just can’t match.

Here are five things fiberglass door ads don’t tell you.

1. “Wood Look” Isn’t the Same as Real Wood

Fiberglass doors are often textured or painted to mimic wood grain, but up close, the difference is clear. True wood doors offer authentic variation, richness, and character that can’t be replicated by synthetic materials. No two wood doors are ever alike, making them a genuine statement piece.

2. Fiberglass Can Still Crack and Warp

Ads often claim fiberglass doors are “maintenance-free.” In reality, fiberglass can crack, split, or warp when exposed to extreme temperatures or direct sunlight. Unlike wood, which can be refinished or repaired, damaged fiberglass usually means full replacement.

3. Limited Lifespan Compared to Solid Wood

While fiberglass doors may last 15–20 years, a high-quality solid wood door can last decades—even generations—when properly cared for. That longevity makes wood a smarter long-term investment.

4. Less Insulation Value Than You Think

Fiberglass doors are marketed as energy-efficient, but their insulation often comes from foam cores that can break down over time. Solid wood naturally provides excellent insulation and durability, helping keep your home comfortable year-round.

5. Lower Impact on Home Value

Curb appeal matters. A solid wood door adds authenticity and elegance that buyers recognize instantly. While fiberglass can look fine from a distance, it rarely delivers the same impression—or resale value—that natural wood brings to your home.
