How to Replace an Interior Door and When to Hire a Contractor

Replacing an interior door may seem like a straightforward home improvement project, but it’s a task that requires precision and the right tools. Whether you’re upgrading for aesthetic reasons or replacing a damaged door, knowing how to do the job correctly is essential. In this blog post, we’ll cover the steps for replacing an interior door, when to consider hiring a professional, and how Big D’s Handyman Service can make the process hassle-free for homeowners in Olympia, Washington.
Tools and Materials You’ll Need
Before starting your door replacement project, gather the following tools and materials:
- New door (pre-hung or slab)
- Measuring tape
- Screwdriver or drill
- Hammer
- Wood shims
- Level
- Pry bar
- Chisel
- Sandpaper
- Paint or stain (if needed)
- Hinges and hardware (if not reusing old ones)
Steps to Replace an Interior Door
- Measure the Door Opening
- Measure the width, height, and thickness of the existing door to ensure the new one fits correctly. For pre-hung doors, measure the door frame as well.
2. Remove the Old Door
- Use a screwdriver or drill to remove the hinges from the door frame. Lift the old door off its hinges and set it aside. If you’re replacing a pre-hung door, use a pry bar to carefully remove the door frame and trim.
3. Prepare the Door Frame
- Check the door frame for any damage, such as cracks or warping. Repair as needed to ensure the new door fits properly. Use sandpaper to smooth rough edges.
4. Fit the New Door
- If you’re installing a slab door, align it with the existing hinges and mark where the hinges need to be attached. Use a chisel to create recesses for the hinges. Attach the hinges to the door and frame.
- For pre-hung doors, position the new door frame in the opening. Use wood shims to adjust the fit and ensure it’s level and plumb.
5. Secure the Door
- Once the door is properly aligned, attach the hinges to the frame using screws. Test the door to ensure it opens and closes smoothly.
6. Install Hardware
- Attach the doorknob, latch, and other hardware. Make sure everything is securely fastened and functioning correctly.
7. Paint or Stain (if needed)
- If your new door isn’t pre-finished, apply paint or stain to match your interior decor. Allow it to dry completely before use.
When to Hire a Contractor
While replacing an interior door can be a DIY project, there are situations where hiring a professional is the best choice:
- Complex Door Frames: If your door frame is damaged or uneven, adjusting it properly requires expertise and specialized tools.
- Custom Door Sizes: Installing a non-standard door size may involve cutting or modifying the door, which can be challenging without experience.
- Time Constraints: A professional can complete the job quickly and efficiently, saving you time and stress.
- Multiple Doors: If you’re replacing several doors, the project can become overwhelming and time-consuming.
- Ensuring a Perfect Fit: A poorly installed door can lead to issues like uneven gaps, sticking, or difficulty closing.
