How to Install Prehung Double Interior Doors: A Step-by-Step Guide

Replacing or installing new doors can significantly enhance the aesthetics and functionality of your home. Prehung double interior doors are a convenient option because they come with the door jambs and hinges already installed, making the installation process easier and faster. Follow this comprehensive guide to learn the essential steps involved in installing prehung double interior doors like a pro. ### Preparation: Before beginning the installation, gather the necessary tools and materials, including a level, tape measure, pencil, reciprocating saw, hammer, pry bar, wood shims, door stop molding, and a screwdriver. Remove the old door and trim if necessary. ### Step 1: Measure and Trim the Opening Measure the rough opening height and width using a tape measure and mark the cutting lines on the jambs. Use a reciprocating saw to carefully cut the jambs to size, ensuring they fit snugly into the opening. ### Step 2: Install the Jambs Position the jambs into the opening and align them using a level. Use wood shims to fill any gaps between the jambs and the wall framing, ensuring the jambs are plumb and square. Secure the jambs using hammer-in wedge anchors or screws. ### Step 3: Hang the Door Lift the prehung door into the opening and align the hinges with the hinge recesses in the jambs. Rotate the top hinge pins into the top hinge recesses until they snap into place. Carefully lower the bottom hinge pins into the corresponding recesses and tap them in gently to secure them. ### Step 4: Adjust the Swing Check the door swing and make any necessary adjustments. Use a pry bar to gently pry open the door or push it closed to adjust the alignment. Once the door swings smoothly and fits snugly against the stop molding, tighten the hinge screws to secure the door in place. ### Step 5: Install the Door Stop Molding Cut the door stop molding to the desired length and secure it to the jambs using screws. This will prevent the door from swinging beyond its intended range. ### Step 6: Install the Lockset Mark the location of the lockset on the door and jamb using the provided template. Drill the necessary holes and install the lockset according to the manufacturer's instructions. ### Step 7: Final Adjustments Check the door operation once more, ensuring it opens and closes smoothly. If necessary, make minor adjustments to the strike plate or hinge tension to achieve the desired fit and function. ### Troubleshooting: - If the door binds when opening or closing, check for warped jambs or misaligned hinges. Adjust accordingly. - If there is a gap between the door and the jambs, insert additional shims to fill the space. - If the door does not swing smoothly, inspect the hinges for any obstacles or wear. Replace or adjust the hinges as needed. By following these steps carefully, you can successfully install prehung double interior doors that will not only enhance the beauty of your home but also provide years of reliable service.
