Slab Replacement vs. Pre-Hung Doors: Which One Do You Need?

May 9, 2025

When it comes to upgrading or replacing a door, homeowners often encounter two main options: slab replacement and pre-hung doors. While both choices serve the same primary function—providing access and security—the differences in structure, installation, and use cases make them suitable for different situations. Understanding these distinctions is key to making the right decision for your home improvement project.

What Is a Slab Door Replacement?

A slab door is essentially just the door itself—no frame, no hinges, no extras. When you opt for a slab replacement, you’re only swapping out the existing door, keeping the frame and hardware intact. This option is ideal for homeowners who already have a well-maintained frame and want a more budget-friendly solution. It also allows for more customization in design and material selection.



However, slab replacements can be tricky if you're not experienced with door installation. You’ll need to align the hinges and drill holes for the handle and lock, which requires precision. If your door frame has shifted over time or is damaged, a slab replacement might not seal properly or hang evenly.

What Is a Pre-Hung Door?

A pre-hung door includes the door itself, already attached to a new frame with hinges. It often comes pre-drilled for the lockset and includes a threshold. Pre-hung doors are designed for full-frame replacements, making them perfect when the existing frame is warped, rotting, or out of alignment.



This type of door is easier and faster to install for many professionals, as it reduces the guesswork. However, pre-hung doors can be more expensive and may require modifications to the wall opening. The installation can also be more labor-intensive, especially for exterior doors, since you'll need to remove and replace the trim and possibly adjust the subfloor.

Cost and Installation Considerations

In general, slab replacements are more affordable upfront but require skill to install properly. Pre-hung doors, while pricier, offer a more comprehensive solution and are often quicker to install when replacing a full door and frame. If your home has shifted over time or the old frame shows signs of damage, a pre-hung option may save you from future headaches.



On the flip side, if you're only looking to upgrade the look of an interior door and your frame is solid, a slab replacement is likely the more economical and straightforward choice.

When to Choose Which Option

  • Choose a slab replacement if:

Your existing frame is in good condition, you’re comfortable with basic carpentry, or you want a cost-effective way to update an interior door.


  • Choose a pre-hung door if:

 Your door frame is damaged, you're installing a new exterior door, or you want a quicker, full-frame solution with fewer measurements involved.
