Replacing an interior or exterior door is one of the most visible updates you can make to a home, but the cost is rarely straightforward. The simple answer to how much a door costs to replace ranges from $200 for a basic hollow-core interior door to $2,500 or more for a high-end fiberglass entry door, with the national average landing around $1,200 per door. This wide variance is driven by a combination of factors including material choice, door size, finish quality, labor rates in your area, and whether you are installing a pre-hung unit or just the door slab.
Material Choices and Their Price Points
The material you select is the single biggest driver of cost, and it directly impacts longevity, maintenance, and aesthetics. When researching how much to replace a door, you will encounter four primary categories, each with a distinct price bracket.
Hollow Core: Often the most budget-friendly option, these doors consist of a lightweight frame with a honeycomb interior. Priced between $50 and $150, they are suitable for interior closets, bedrooms, or other low-traffic areas where insulation and soundproofing are not critical.
Solid Core: A step up in quality, these doors feature a composite wood center, offering better sound insulation and a more substantial feel. You will typically spend between $150 and $400 for a solid core door, making them a popular choice for main bedrooms and bathrooms where privacy is essential.
Fiberglass: Gaining immense popularity due to their durability and low maintenance, fiberglass doors mimic the look of wood but resist warping, cracking, and rusting. The cost usually sits in the $200 to $500 range for interior use, while exterior-grade models with steel frames can climb to $1,500.
Wood: The premium choice, wood doors offer timeless beauty and can be refinished over the years. Prices start around $400 for basic hardwoods and can easily exceed $3,000 for exotic species like mahogany or custom craftsmanship. These are ideal for historic homes or high-end renovations where curb appeal is paramount.
Size Matters: Dimensions and Adjustments
Standard interior doors in the United States are typically 80 inches tall and 30 inches wide, while exterior front doors are often 80 by 36 inches. However, if your frame deviates from these standards, the cost to replace a door will increase. Custom sizing requires more precise cutting and potentially additional shimming during installation. Furthermore, if you are replacing a French door, bi-fold door, or a pocket door, the mechanical complexity and specialized hardware will add $500 to $1,500 to the total project cost compared to a standard hinged door.
Hardware, Trim, and the Finish Line
The door itself is only part of the equation; the surrounding components significantly impact the final bill. If you opt for a basic doorknob set, you might spend $50 to $100. However, upgrading to a keyed entry system with a deadbolt, or incorporating a smart lock, can push that hardware cost to $200 or more. Don’t forget the trim—the jambs and baseboards—which might need replacement if the existing wood is damaged. Finally, finishing touches like custom staining or painting add labor time; a professional paint job typically costs between $100 and $200, while on-site staining can run $150 to $300.
Labor: The Invisible Cost
Unless you are comfortable with a saw and a level, labor is a necessary expense in door replacement. Professional installers charge anywhere from $100 to $300 per door, depending on the region and the complexity of the job. Factors influencing labor rates include the need to remove and dispose of the old door, shimming a new frame perfectly plumb, and repairing any rotten wood in the surrounding wall. If you are installing multiple doors in a home, some contractors offer volume discounts, which can bring the per-door labor cost down slightly.
Exterior vs. Interior Cost Breakdown
It is helpful to look at exterior and interior replacements separately, as the requirements differ greatly. Interior doors are generally lightweight and focus on aesthetics, resulting in lower costs. Exterior doors, however, must provide security, insulation, and weather resistance. This necessitates thicker materials, robust locking mechanisms, and high-quality weather stripping. Below is a breakdown of typical costs to give you a concrete reference when budgeting.
| Door Type | Material | Average Cost Range |
|---|---|---|
| Interior Bedroom | Hollow Core | $200 – $500 (installed) |
| Bathroom | Solid Core | $300 – $800 (installed) |
| Exterior Front Entry | Fiberglass/Steel | $1,500 – $3,000 (installed) |
| Patio Door | Glass/Fiberglass Composite | $1,000 – $3,000 (installed) |
Maximizing Your Investment
To ensure the money you spend translates into long-term value, focus on energy efficiency and security. Look for doors with the ENERGY STAR label, which indicates they meet strict guidelines for insulation. This can save you money on heating and cooling bills over time. For exterior doors, consider a steel or fiberglass shell with a polyurethane foam core for superior thermal performance. While the upfront cost might be higher, the durability and reduced energy consumption often justify the investment, making the question of "how much to replace a door" not just a cost, but a value calculation.
