What Does It Cost to Hang a Door in 2026?
The cost to hang a door typically falls in these ranges as of 2026:
| Door Type | Typical Installed Cost |
|---|---|
| Interior slab door | $444 – $700 |
| Interior pre-hung door | $552 – $841 |
| Exterior entry door | $550 – $2,400 |
| Specialty doors (French, pocket, barn) | $800 – $2,600+ |
Most homeowners spend somewhere between $500 and $2,000 per door, depending on the type, material, and condition of the existing opening. Labor alone typically runs $30 to $90 per hour, and the full job usually takes 2 to 4 hours.
Those numbers can shift — sometimes a lot — based on where you live, whether the frame needs work, and what hardware you choose. That’s exactly what this guide breaks down.

The Real-World Cost to Hang a Door in 2026
When budgeting for a home improvement project, looking at a single average price can be incredibly misleading. A widely cited range across common door projects is about $500 to $2,000 per door, with an overall national average of around $1,200. However, this average combines basic interior closet doors with massive, multi-lock fiberglass entry doors.
To help you build a realistic budget, we must separate these projects by their actual scope. The physical demands, sealing requirements, and structural support needed for an interior bedroom door are completely different from those of an exterior front entry door.
Below is a detailed breakdown of what you can expect to pay for different door categories in 2026, including both the door itself and professional labor.
| Door Category | Average Materials Only | Average Labor Only | Total Estimated Cost (Installed) |
|---|---|---|---|
| Interior Hollow-Core Slab | $50 – $200 | $100 – $250 | $150 – $450 |
| Interior Solid-Core Pre-Hung | $150 – $500 | $150 – $300 | $300 – $800 |
| Standard Steel Entry Door | $300 – $800 | $250 – $600 | $550 – $1,400 |
| Premium Fiberglass Entry | $800 – $2,000 | $350 – $800 | $1,150 – $2,800 |
| Sliding Patio / French Doors | $800 – $3,000 | $500 – $1,500 | $1,300 – $4,500+ |
| Pocket or Barn Doors | $200 – $1,000 | $400 – $1,500 | $600 – $2,500+ |
Average Cost to Hang a Door: Interior vs. Exterior
The division between interior and exterior projects is the single most significant factor in your overall budget.
For interior projects, the national average cost to hang an interior door starts at $444 to $675 per door. When you look at the wider market, interior door installation is commonly budgeted around $350 to $1,250 installed, with a realistic average of around $800. These projects are simpler because the doors do not have to block sub-zero Missouri winter drafts or keep out driving summer rain.

On the other hand, exterior door installation is commonly budgeted around $550 to $2,400 per door, with a national average of around $1,450. Why is it so much higher? An exterior door is a critical part of your home’s security and thermal envelope. It requires heavy-duty hinges, weatherstripping, threshold sealing, and often extensive structural framing support.
How Materials and Door Types Impact the Cost to Hang a Door
The physical material of the door determines both its raw purchase price and the physical effort required to hang it.
- Hollow-Core Wood/Composite: Extremely light and budget-friendly. These are standard for interior closets and bedrooms. Because they are lightweight, they are easy to align and quick to hang.
- Solid-Core Wood or MDF: These provide excellent sound dampening and a premium feel. However, because they are heavy, they require sturdier framing, exact hinge mortising, and often a second set of hands to hold in place during installation.
- Steel: Steel doors offer incredible security and value, typically costing $300 to $800 for the unit. They are durable but must be perfectly square in their frames to prevent binding.
- Fiberglass: The gold standard for modern exterior doors. Fiberglass won’t warp or rot like wood, and it won’t dent like steel. However, premium fiberglass entry systems can easily run $700 to $2,000+ before labor.

Pre-Hung vs. Slab Door Installation Costs
One of the most common points of confusion for homeowners is the difference between a “slab” door and a “pre-hung” door.
A slab door is just the door itself—a rectangular piece of wood, fiberglass, or steel with no frame, no hinges, and sometimes not even a hole drilled for the doorknob. A pre-hung door comes already mounted inside a matching wooden frame (jamb), complete with hinges attached and the lockset holes pre-bored.
- Slab Door Installation: While a slab door is cheaper to buy, it is often more expensive and time-consuming in labor. The carpenter must manually trim and plane the door to fit your existing frame, mortise (chisel out) the hinge pockets, and drill the lockset holes.
- Pre-Hung Door Installation: In May 2026, the national average cost to hang a pre-hung door starts at $552 to $841 per door. While the material cost is higher up front, installing a pre-hung door is often faster and more reliable because the door is already perfectly aligned with its frame.

Labor Cost Breakdown: Hourly Rates and Project Timelines
Labor is a massive component of the cost to hang a door. Understanding how contractors charge and how long the job should take will keep you from overpaying.
Hourly vs. Flat-Rate Pricing
Door installers generally charge in one of two ways:
- Hourly Rates: A professional door installer or skilled carpenter typically charges between $30 and $90 per hour. A simple interior pre-hung door might take 2 hours ($60 to $180 in labor), while a complex exterior door with sidelights could take 5 hours ($150 to $450 in labor).
- Flat-Rate Pricing: Many experienced contractors prefer to charge a flat rate per opening. This is highly beneficial for homeowners because it protects you if the installer runs into unexpected alignment issues that drag the job out.
The Minimum Charge Warning: If you are only hiring a professional to hang a single interior closet door, expect to pay a “minimum charge” or trip fee. Most reputable contractors cannot afford to send a truck, tools, and a two-man crew to a home for a one-hour, $50 job. Minimum service calls typically range from $150 to $300, which is why we always recommend bundling multiple door replacements together.
What is Included in a Professional Installation Quote?
When you receive a quote to hang a door, you must look closely at the line items. A comprehensive, professional quote should include:
- Site Preparation: Laying down drop cloths to protect your flooring.
- Basic Labor: Measuring, leveling, shimming, and securing the door frame.
- Hardware Installation: Mounting the hinges, doorknobs, strike plates, and deadbolts.
- Trim and Casing: Re-installing or installing new decorative trim around the opening.
- Cleanup and Disposal: Sweeping up wood shavings and hauling away the old door.

Key Factors That Influence Your Final Estimate
If you have ever received home improvement quotes that varied by hundreds of dollars, it is because every home presents its own unique set of challenges. Here are the variables that adjust your estimate up or down.
Rough Opening Condition and Frame Repairs
The “rough opening” is the structural framing inside your wall that holds the door assembly. In older homes—which we have plenty of in the St. Louis area—settling can cause these openings to become warped, out of plumb, or completely out of square.
If an installer opens up your wall and finds dry rot, water damage, or termite activity around an old exterior door, that frame must be rebuilt before the new door can be hung. Rebuilding a rough opening or replacing a rotted exterior frame typically adds $200 to $650 to the project cost.
Regional Labor Markets and St. Louis Pricing
Labor rates are highly dependent on your local economy. While coastal metropolitan areas face incredibly high labor rates, the Midwest offers highly competitive pricing.
For homeowners in our local service areas—including St. Louis, St. Charles, St. Peters, Florissant, Creve Coeur, Maryland Heights, O’Fallon, and Chesterfield—pricing is highly stable but influenced by local weather patterns. Our hot, humid summers and freezing winters mean that exterior doors must be sealed with extreme precision to prevent energy loss.

DIY vs. Professional Door Installation
Many homeowners look at a door and think, “It’s just a piece of wood on some hinges. How hard can it be?” While some door projects are highly DIY-friendly, others can quickly turn into a structural nightmare.
When to Hire a Professional Carpenter
We recommend hiring a professional for:
- Any Exterior Entry Door: If an exterior door is hung incorrectly, it can allow water to leak into your subfloor, leading to thousands of dollars in structural rot. It also compromises your home security.
- Load-Bearing Wall Modifications: If you want to widen an opening (for example, turning a single door into double French doors), you are dealing with structural framing that supports your roof. This requires professional headers and permits.
- Custom or Oversized Doors: Heavy solid-wood doors or custom glass patio sliders require exact structural calculations and specialized tools.

Smart Ways to Reduce Your Installation Costs
If you want to keep your project costs down without sacrificing quality, use these proven strategies:
- Keep Your Existing Frame: If your current door frame is perfectly square, plumb, and free of rot, you can buy a slab door and have it cut to fit the existing frame. This can save you $200 to $650 in framing and trim costs.
- Choose Standard Sizes: Standard doors are 80 inches tall and 28, 30, 32, or 36 inches wide. Ordering a custom size can instantly add $200 to $1,000 to the price of the door.
- Bundle Your Projects: Instead of hiring a contractor to replace one door this year and another next year, replace 3 to 5 doors at once. This allows the contractor to maximize their time on-site, and they will often pass a 10% to 20% labor discount on to you.
Frequently Asked Questions About Door Installation
What are the hidden costs of door installation?
The most common hidden costs are disposal fees (typically $40 to $200 to haul away heavy old doors), trim replacement (if the old trim breaks during removal), and painting/finishing. Most door installers do not paint; they hang the door and leave it primed. You will need to budget for paint or stain to finish the job.
How long does it take to hang a new door?
An experienced professional can hang a standard interior pre-hung door in 1 to 2 hours. A standard exterior entry door typically takes 3 to 5 hours because of the extensive weatherproofing, threshold adjustment, and lockset alignment required.
Does replacing an entry door improve energy efficiency?
Yes! Old, drafty doors are a major source of energy loss. Modern exterior doors feature insulated fiberglass cores and tight-fitting weatherstripping that can reduce your heating and cooling bills by 10% to 20%. Plus, replacing an entry door is a fantastic investment, recouping about 75% of its cost in added home value when you sell.
