Doors are one of the most important parts of a home. They keep you safe, help control temperature, and add beauty to every room. But when it’s time to replace or install new doors, one question always comes up — how much does it cost?
In this guide, we’ll walk you through the average costs for both interior and exterior door installation, what affects the price, and when it’s best to call a professional. By the end, you’ll have a clear idea of what to expect before your next home project.
Average Door Installation Costs (Quick Overview)
The price of installing a new door can change a lot depending on the type of door, material, and labor.
Here’s a simple breakdown for 2025:
Type of Door | Average Total Cost |
Interior Door | $150 – $400 |
Exterior Door | $400 – $1,800 |
Interior doors are lighter and easier to install, while exterior doors are thicker and need more time, insulation, and hardware.
What Affects Door Installation Costs?
Several factors can change how much you’ll pay for a door installation. Let’s look at the most common ones:
- Type of door: A plain bedroom door costs less than a sliding glass or French door.
- Material: Wood doors are classic but more expensive. Fiberglass and steel doors cost less and last longer.
- Labor: Handyman and contractor rates vary by area, but expect to pay around $50–$100 per hour.
- Framing and trim: If the doorway needs new framing or drywall repair, the cost will increase.
- Hardware: Handles, locks, and hinges add to the total price. High-security or smart locks can also raise costs.
- Location: Installing an exterior door requires sealing and weatherproofing, which takes more time and care.
Interior Door Installation Costs (Detailed Breakdown)
Interior doors are usually easier and quicker to install than exterior ones.
Average cost: $150 to $400 per door
Labor: $75 to $200
Materials: $50 to $200
Common types include:
- Bedroom or bathroom doors: Often hollow-core, lightweight, and easy to replace.
- Closet doors: Can be hinged, sliding, or bifold; sliding types may need extra tracks.
- French or barn doors (interior): Add style but can double the price because of hardware and alignment.
Tip: If your existing frame is in good shape, reusing it can save you about $50–$100.
Exterior Door Installation Costs (Detailed Breakdown)
Exterior doors cost more because they need to be secure, insulated, and weatherproof.
Average cost: $400 to $1,800 per door
Labor: $200 to $600
Materials: $200 to $1,000
Here are common exterior types:
- Front entry doors: $500–$1,500 (fiberglass or wood).
- Steel security doors: $400–$900.
- Sliding glass patio doors: $800–$2,000 depending on size and glass quality.
- French doors: $1,000–$2,500, more if they open to a patio.
- Storm or screen doors: $200–$600.
- Weatherproofing matters: Good insulation and sealing around the frame prevent drafts and save on energy bills.
DIY vs. Hiring a Professional
Installing a door looks simple, but it’s not always an easy DIY job.
DIY pros:
- You can save on labor.
- It’s a good small project if you already have tools and some experience.
DIY cons:
- A small mistake can cause gaps, squeaks, or doors that won’t close right.
- You’ll need to measure perfectly and possibly adjust hinges or frames.
For many homeowners, hiring a professional saves time and ensures the job is done right the first time.
