Wood vs Fiberglass vs Steel Door Costs & Features Compared
Wood Door Costs
Wood doors are a go-to choice for enhancing curb appeal and showcasing a home’s architectural style. However, they come with higher upfront and ongoing costs. Breaking down these expenses can help you decide if the investment aligns with your needs.
Material and Installation Costs
The cost of a wood door varies widely based on its design and features. A basic wood door slab typically costs between $500 and $3,000, while custom or luxury designs can exceed $8,000 just for the door itself. Adding professional installation raises the total cost, with most mid-range pre-hung doors falling between $1,000 and $2,500. For doors with extras like sidelights or transoms, the price can climb to $3,000–$12,000 or more.
Several factors can significantly influence the final price:
| Factor | Effect on Cost |
|---|---|
| Wood Species | High-end hardwoods like mahogany or white oak drive up material costs |
| Design Complexity | Features like double doors, taller dimensions, or intricate carvings increase expenses |
| Glass Packages | Decorative glass inserts, sidelights, or transoms can add $1,000–$4,000 |
| Frame Condition | Repairs for issues like rot at the sill or jamb can add $130–$380+ |
Labor costs make up roughly 30–35% of the total. Professional labor typically runs $30–$90 per hour, with a standard door replacement taking 2–3 hours. Choosing a pre-hung door – where the door comes pre-mounted in its frame – can reduce installation time and improve the door’s seal compared to fitting a slab door into an existing frame.
After installation, it’s important to consider the ongoing maintenance costs that come with wood doors.
Maintenance Requirements
Wood doors require regular upkeep, particularly in areas with high sun exposure. Refinishing is often needed every 2–4 years, and doors facing direct sunlight may require even more frequent attention. Using a low-quality varnish can lead to chalking within just one season. Routine maintenance includes cleaning, inspecting weatherstripping, and checking for finish wear around the lower rail and stiles. Staying on top of these tasks can help avoid the need for a costly full strip-and-refinish job.
For doors exposed to intense sunlight, applying a marine-grade or UV-stable topcoat can extend the life of the finish. While this adds to maintenance costs, it’s an effective way to protect your investment.
Durability Considerations
Wood’s natural tendency to absorb moisture can lead to expansion and contraction, which may cause sticky latches in the summer or gaps in the winter. Without proper sealing, the bottom rail – closest to the threshold – is especially vulnerable to rot. Despite these challenges, a well-maintained wood door can last over 60 years.
Scratches and dents are also easier to repair on wood compared to other materials. To maximize durability, wood doors perform best when installed under a covered porch or entryway that shields them from direct rain and prolonged sunlight. If your entryway lacks this protection, you may need to plan for more frequent maintenance and potential repairs.
While wood doors bring unmatched charm and elegance, their upkeep and durability demands should be carefully weighed against their overall value.

Fiberglass Door Costs
Fiberglass doors sit comfortably in the mid-to-high price range of exterior doors. While they generally cost more upfront than steel doors, they tend to be less expensive than top-tier wood options. They also offer long-lasting durability with very little maintenance required.
Material and Installation Costs
A basic fiberglass door slab starts at around $150, but high-end custom designs featuring decorative glass can climb to $3,000. Installation costs typically add another $200–$800, bringing the total installed price to anywhere between $400 and $3,500. If you’re considering a complete entry system with sidelights or a transom, the price can jump to $3,000–$12,000 or more.
Opting for a pre-hung unit – where the door is pre-installed in its frame – can be a smart investment. While it costs more upfront, it simplifies installation and ensures a snug weather seal right away.
Durability and Maintenance
Fiberglass stands out as one of the toughest door materials available. Unlike wood, it doesn’t warp, rot, or absorb moisture. And, unlike steel, it won’t dent or rust. As Telegraph explains:
"Fiberglass has become the default recommendation… properly made, it does not swell, warp, or rot." – Telegraph
Maintenance is minimal – just give it a quick wash and occasionally check the weatherstripping. However, heavy sun exposure can cause the finish to fade over time. For doors facing south or west, it’s wise to select models with UV-rated resin systems to protect against surface damage and color changes. Quality fiberglass doors can retain 85–90% of their original color even after a decade of direct sunlight. This durability also translates to excellent thermal performance with little effort required to keep them looking and functioning well.
Energy Efficiency Benefits
Fiberglass doors don’t just excel in durability – they’re also highly energy-efficient. Thanks to their foam core construction, often made of polyurethane, these doors offer excellent insulation. Most fiberglass doors without windows achieve an R-value of R-5 to R-6, compared to the R-2 to R-3 range for solid wood doors. Switching from a traditional wood door to a foam-core fiberglass model can significantly reduce heat loss through the door slab.
Because fiberglass doesn’t expand or contract much with temperature changes, its weatherstripping stays tight year-round – something wood doors struggle to maintain. This stability can help reduce heating and cooling costs, especially in extreme climates. Additionally, many fiberglass doors meet Energy Star certification standards, which may make them eligible for federal tax credits.
Steel Door Costs
Steel is one of the most budget-friendly materials for exterior doors, offering both affordability and security.
Material and Installation Costs
A basic steel door slab can start at just $150, while mid-range options featuring decorative glass or upgraded finishes range from $200 to $2,000. For more elaborate setups, like double doors with sidelights and transoms, the cost can climb to $12,000 or more when installed. For a standard single-door installation, most homeowners spend between $200 and $700 total.
However, additional features can add up quickly. For example:
- Sidelights: $400–$2,000
- Transoms: $300–$900
- Decorative glass panels: $300–$1,600
- Smart locks: $120–$500
If your existing door frame is in good condition, you can save $200–$650 by opting for a slab door rather than a pre-hung unit. Labor costs typically make up 30%–35% of the total expense, with professional installers charging $30–$90 per hour.
Durability and Maintenance
Steel doors excel at resisting forced entry. Instead of cracking or breaking, they dent under impact, which enhances their security. As Bob Vila explains:
"Hit vigorously, steel doors may dent, but will rarely break or warp. Since it is nearly impervious to damage by force, steel is one of the strongest and best front doors for security."
That said, steel doors are prone to cosmetic damage. Scratches or dents can expose the metal to moisture, leading to rust if not promptly repaired. To prevent corrosion, repaint any damaged areas immediately. For added protection, applying a coat of car wax or linseed oil annually can shield the surface from the elements. Without regular upkeep, rust can start to appear within 8–12 years, but with proper care, a steel door can last anywhere from 30 to 100 years.
Keep in mind, steel doors are about 40% heavier than fiberglass alternatives, weighing 60–80 lbs. If you’re replacing an older door, make sure your frame can handle the extra weight. Reinforcing the frame, if necessary, may cost an additional $200–$500.
Best Use Cases for Steel Doors
Steel doors are ideal for rental properties, budget-conscious remodels, and homes where security is a top priority. They offer an impressive return on investment, with a potential ROI of up to 188%, according to the Remodeling 2024 Cost vs. Value Report. However, if you live in a coastal or high-humidity area, be prepared for more frequent maintenance. Salt air can cause rust to appear in as little as 18–24 months without proper protection.
