What is a Prehung Door?A prehung door is simply a door that arrives preassembled and hanging from its frame. This self-contained unit will fit nicely into the door opening and saves you a lot of time. Depending on the type of door (exterior vs. interior), the door unit will arrive with different parts attached. Before you begin, it’s important to understand the different parts of a door that are generally included with prehung doors.
Slab: First, it’s necessary to know the difference between a prehung vs slab door. Slabs or slab doors refers to the actual door regardless of frame, style, and hardware. When purchasing anything from swinging French Doors to a sliding barn door or pocket door, you can have the option of ordering only the door panel (the slab). But when you order a prehung door, this slab will arrive with everything necessary attached whether it’s made of wood, steel, or glass.
Door Slab Hinge Prep: In order for a door to swing or slide, the slab needs to be prepped with hinges or rollers. When you order a prehung door, this hardware will be installed in the specific, necessary location. Depending on the style and function of the door, the placement and number of rollers and hinges will vary.
Bore: Although many prehung doors do not come prepped for a doorknob or bolt, Rustica offers the option of prepping for this specific hardware (you can even order the knob or bolt right on our site). A bore simply refers to a predrilled hole in the door where you can eventually place your hardware. With Rustica, you can choose the exact placement and width. If this seems confusing, customer service is available to help you. Generally, these bores are drilled at 2 3/8" and 2 1/4" from the edge of the door.
Door Bottom/Sweep: Door sweeps are only for exterior doors. The bottom or sweep of the door references a piece of wood (or other material) installed underneath the bottom of the door. This piece seals off any space or gap that remains between the bottom edge of the door and the threshold without causing the door to brush against the threshold itself. With a door sweep properly installed, the door will perfectly brush the floor as it opens and closes.
Jamb: The jamb includes the two vertical sides of the doorframe. Depending on your type of door swing, the door will be hung from either the left or right jamb. Jambs are commonly made from various materials, including composite or solid wood, metal, and durable plastic composites.
Stop: A door stop is a piece of metal or wood that is installed horizontally on the underside of both door jambs, connecting the two. This piece stops the door as it closes.
Threshold: Available only for exterior doors, the threshold runs along the bottom of the door frame horizontally. It’s placed directly opposite the door stop and seals the gap between the floor and the bottom of the door. Typically made of wood or metal, the threshold has several important roles, including providing energy efficiency.
Weather Stripping: Without weatherstripping, your home will fall victim to intruding wind and water. Prehung exterior doors are commonly applied with a sealer that prevents elements such as these from entering a room. This is known as “weatherstripping.”
Door Jamb Hinge Prep: In order for the door jamb to fit appropriately into its opening, carpenters prep the jamb with hinge notches using a machine or chisel. Similar to door slab hinge prep, these notches will fall perfectly for installation.
Strike Plate Prep: The strike plate is a metal slab installed onto the jamb with screws. It has an opening that allows the latch to move in and out. This plate can be customized according to the thickness of the door and the type of latch used. Carpenters use a chisel to notch out the strike plate area.
Brick Mold: The molding placed around an exterior door between the wall and the slab is called the brick mold. Its main purpose is to fill the gap that remains when the door is installed in its opening. Usually, this type of molding is made of wood—either solid or composite.
Adjustable Sill: Found underneath the threshold of an exterior door, a sill is the bottom part of the frame that rests on the floor’s foundation.
Sidelights: Sidelights, or sidelites, are long, vertical windows next to one or both sides of a door. Sidelites will require a slightly larger door opening and are most common in front entry doors or patio doors.
Benefits of Prehung DoorsWith so many parts of a door already included with a prehung door, it’s easy to see the benefits of ordering interior and exterior doors prehung.
Installation: Installing a pre-hung door is a quick and easy process. Because the door comes with all of the necessary hardware installed in the correct areas, this option is perfect for everyone—from a first-time homeowner to a DIY veteran. You’ll save time, effort, and money by installing a prehung door.
Weather-Resistance: Exterior pre-hung doors arrive with weather stripping and are already assembled to create a weather-tight seal against the door opening. You don’t need to do anything yourself to ensure that this door will keep out the elements and maintain the desired temperature in your home.
Customization: When you purchase a prehung door from Rustica, you can customize everything from the dimensions and hardware to the style and finish. Your custom door arrives completely finished so you don’t need to go searching for the perfect handle or hinge to complement the paint or stain of your door slab. Instead, the finished product will arrive exactly as you imagined based on the many beautiful and unique options that Rustica provides.
Prehung Door Framing OptionsWith a prehung door, there’s no need to worry about building a new frame or retaining an older frame. No matter the type of door, prehung doors come with all of the frame components installed in place, ready to be placed in the wall opening. This is especially helpful when altering the size of your door opening or replacing a deteriorating or damaged frame.
Still, some homeowners might find it most practical to replace only parts of a door frame since it is made of many components such as the jambs, sill, door stop, weatherstripping, and jamb casing. Each of these components can be replaced or preserved. However, choosing one and not the other might result in a little more work compared to receiving a fully assembled pre-hung door.
Sometimes, it makes sense to preserve parts of your existing door. For example, you may only need to replace the door jambs instead of the entire frame. Remember, the jamb includes the two vertical sides of a door frame where the hinges are installed. If the other parts of the door frame are in good condition and fit with the dimension and style of your door opening and new door slab, it might be easier and more economical to just replace the jambs.
Prehung Door Hardware OptionsRustica allows you to completely customize your prehung door. You have a wide variety of hardware options available to create the perfect door—whether you want to install anything from prehung French doors and prehung closet doors to prehung bedroom doors and double doors. Keep in mind that for interior and exterior double doors, you’ll need to order twice the number of the following:
Hinges: There are two types of hinges available for your prehung door: Square Corner Ball Bearing Hinge and Rounded Corner Ball Bearing Hinge. The only difference between these two is the shape of the hinge plate itself—the former being square, and the latter rounded. Hinges, like other hardware, come in a variety of finishes, no matter the shape. You can select Flat Black or Satin Chrome for a sharp, modern look or go with something more traditional, like French Antique or Tumbled White Bronze.
Handles: If you choose to have the slab arrive with a door knob boring, you’ll need to determine its placement. Once this is completed, you can browse Rustica’s options for handles and pulls. Depending on your door, the handles and pulls may need to be purchased separately. Even so, installation will be a breeze since the exact placement will be marked and prepped. This information will always be listed in the customization process, so you’ll know when you need to make an additional purchase.
Determining the best handle for your type of door is an important decision. Prehung sliding doors are often best accompanied by a handle, strap, or pull ring. Popular choices often include the Redwood Barn Door Pull or a flush barn door pull, depending on the type of slide. Hinged doors like interior French doors and Dutch doors can be purchased with levers, such as the San Carlos or the Bern. As well, exterior doors have different options for handles and pulls. All handle options can be customized according to your desired finish.
Locks: For prehung standard hinged interior doors and exterior doors, you can choose from key and electronic locks, deadbolts, or tubular entry sets. Prehung sliding barn doors can also come installed with optional barn door hook locks. Choose from the classic hook and eye or the Rustica Door Latch + Lock, which is the first ever self-latching lock for sliding barn doors.
How to Install Prehung DoorsThere are a few simple steps to install prehung interior and exterior doors. Rustica also provides a quick guide on how to install a prehung door. The steps below are for hinged doors only.
Step 1: Verify that your prehung door is level within the complete door frame. Run a 4-foot level (larger if the door opening is wider) along the floor and mark on the door frame where it shows to be level.
Step 2: Transfer those markings onto the door jamb. Mark the measurement first from the hinge side and then from the knob side.
Step 3: Use the level again to make sure the rough frame is plumb (vertically level) before sliding the door into the opening.
Step 4: After sliding the door in place, make sure that all of your markings on the frame and on the door opening line up. Make sure the door jamb is flush with the wall, then drill a pilot hole at the point where the door meets the shim then screw it in. Finish screwing in the hinge side.
Step 5: If further leveling is required, insert the necessary amounts of shims at the bottom until it is even. Once everything is level, drill in the knob side until secure.
Step 6: Make sure the door swings well and that everything is even. If so, go ahead and complete any necessary finishing touches, such as installing trim or painting and priming if you’ve purchased an unfinished prehung door.
Are Prehung Doors the Right Option for Me?If you are looking for complete customization and easy installation, then the answer is “yes!” A prehung door includes the frame, hinges, and other hardware already assembled. It makes the job of installing a new door and frame much easier. Unless you want to keep your existing door frame, choosing a prehung door is almost always the best choice.
You don’t need to be a DIY guru—you can install your new customized prehung door in just a few hours. With Rustica’s thorough customization process, you’ll be in charge of curating the perfect prehung door crafted to your design needs and inspiration.
