A prehung door is a door that comes ready to install, already mounted in its frame with hinges and stop molding included. Because everything is factory-aligned, installation is quicker, more precise, and convenient, as you don't need to drill or align the hinges yourself. This makes it a smart option if your current frame is damaged, uneven, or if you're working on a new build. Installation involves fitting the entire unit into the rough opening, shimming and leveling it, and then securing it. If you are replacing an existing prehung door, the process is even simpler, often just requiring you to swap the old unit for the new one and secure it with a few screws. Prehung doors typically cost only slightly more (around $20) than a door slab alone, making them an efficient choice.

Yes, prehung doors include a door jamb. Prehung doors are sold as a single piece with the door frame already constructed, including the hinges. The only part missing is the trim, which you add after fastening the door. They are more expensive than slab doors but are quicker and easier to install. Prehung doors come in an array of sizes, so there’s likely an option to fit any doorway you need.

You can attach the hinges to either the door or the frame first, depending on your preference. The order will not affect how the door hangs or the ease of installation. However, we recommend starting with the top hinge over the bottom one for stability, as it’s much easier to support the door from below while you install the top hinge. It will also be easier to pull the door outward from the hinges as it hangs from the top than it would be to push the door toward the hinges, as there’s less clearance on the lock side.

Most of the time, a squeaky door is the result of dry hinges, where metal parts rub together without enough lubrication. Dirt, dust, or rust can also build up inside the hinge and add to the friction. Loose screws or slight misalignment can shift things just enough to create that irritating squeaking noise. Worn-out hinges or swelling wood from humidity changes can also be part of the problem on older doors. A good cleaning and proper lubrication usually take care of it, but if the squeak sticks around, it’s worth checking for bigger issues with the hinges or alignment.
