Pre-Hung vs. Slab Door: What’s the Difference?

Whether you look for a new entrance or a replacement door for a room, you can choose between two basic types, with or without a door frame. So, before you make an order, you need to know the difference between the pre-hung vs. slab door.

Both choices have their pros and cons. While the slab door is just a rectangle-shaped piece of wood (or some other material), the pre-hung door is a complete package with a frame ready for installing. That is why manufacturers recommend the pre-hung door as a better option. However, the slab door is a better choice in some cases. Let’s see.

The slab door is actually a door itself without a door frame or additional parts. Usually, it doesn’t come with the cutouts for hinges, which makes the DIY installation tricky. In most cases, these doors are not exclusively a single piece.

Nowadays, many models have two or more panels, plus you can combine materials, such as wood and glass. The great thing is that the simplicity of this door makes it an ideal option for all custom variations. You can pick out from many, modern or traditional stab doors styles and models, and quickly find the perfect match for your home.

Unlikely the stab door, the pre-hung type comes entirely or partially assembled. When you buy it, you will get the door frame, jambs, and hinges. Sometimes, the door unit contains the door sill and the weather-stripping as well, depending on the purpose of the door.

Keep in mind that the exterior pre-hung door will come with particular additional parts, which the interior door doesn’t need. However, you will get everything you need in both cases so that the installation process can take merely 15 minutes. Even though you are not highly skillful, you probably won’t need more than half an hour to finish the job.

Nowadays, most of the newly built houses have this model. Since they come with the frame, all you need is the opening in the wall, and you can mount your new door without trouble. These models usually come in standard sizes, but you can still choose among numerous patterns and materials.

If the door frame is preserved and you replace one door with another, the slab door is the logical investment. The same goes even if you have an authentic vintage house that the pre-hung door doesn’t fit aesthetically.

On the other hand, when the old door frame is damaged and rotten, the only solution is to take the old door out and install the pre-hung model. This unit is also the smart choice when you want to install the exterior door that offers quality weather protection.

The choice between the pre-hung door and the slab door also depends on whether you want to install the door yourself or hire a professional to do the job. It is crucial to hire someone reliable with enough experience to mount the door and place the hinges correctly.

On the other hand, you can decide to make the door installation a DIY project. In such a case, it is wiser to buy the pre-hung door because the mounting doesn’t require any particular skill. However, don’t forget that this model is quite massive, and you need help to lift and adjust it to the wall opening.

Finally, if you renovate an entire house and don’t have much time, the pre-hung door can speed up the work. The installation of this type will take much shorter than mounting the slab door. So, you can finish the complete remodeling more efficiently by choosing the pre-hung model.
