Carpenters with years of experience in crafting and installing internal doors, use this approach which can easily be copied by a skilled DIY person. Just follow the simple instructions.
Preparation and Selection
- Assess the Opening: Begin by carefully examining the door opening, ensuring it's level and square. Check for any damage or irregularities in the frame, which may require repair or reinforcement.
- Choose the Right Door: Select an interior door that complements the overall aesthetic of the space and matches the dimensions of the opening. Ensure the door is the proper thickness for the frame and hardware.
- Gather Tools: Equip yourself with essential tools like a measuring tape, level, hammer, drill, screwdriver, saw (if necessary), door hinges, doorknob or lever, door stops, door sweep, wood glue, shims, and a chisel.
Door Frame Preparation
- Remove Existing Door: If there's an old door, carefully detach it from the hinges, taking care not to damage the frame. Remove any existing trim or moulding surrounding the opening.
- Repair Damage: If the door frame is damaged, repair any cracks, dents, or warped sections using wood glue and shims. Ensure the frame is structurally sound and level before proceeding.
- Hinge Marking: Accurately mark the hinge locations on the door frame using the level. Ensure the marks are evenly spaced and aligned with the hinge mortises on the door.
- Drilling Pilot Holes: Before attaching the hinges, carefully drill pilot holes for the screws. This will prevent splitting or cracking of the wood.
Attaching the Hinges
- Apply Adhesive: Apply wood glue to the hinge mortises on the door frame. This will enhance the strength and durability of the hinge attachments.
- Positioning Hinges: Carefully position the hinges on the door frame, aligning the hinge knuckles with the marked locations. Ensure the hinges are level and evenly spaced.
- Driving Screws: Secure the hinges to the frame using the appropriate screws. Tighten the screws firmly but avoid overtightening, which could damage the wood.
Door Installation
- Aligning the Door: Carefully place the door into the opening, ensuring the hinges are properly aligned with the mortises on the frame. Ensure the door is plumb (vertically aligned) and square (horizontally aligned) using a level.
- Marking Door Jamb: Mark the locations of the mounting holes on the door jamb, aligning them with the corresponding hinge knuckles.
- Drilling Pilot Holes: Drill pilot holes for the mounting screws on the door jamb. This prevents the wood from splitting during screwing.
- Attaching the Door: Carefully lift the door into place, aligning the pilot holes with the mounting screws on the door jamb. Secure the screws firmly, ensuring the door is firmly attached.
Hardware Installation
- Doorknob or Lever: Follow the manufacturer's instructions to install the doorknob or lever, ensuring it's aligned and properly secured.
- Door Stops: Mount the door stops at the appropriate locations on the frame, ensuring they prevent the door from swinging into walls or furniture.
- Door Sweep: Attach the door sweep to the bottom of the door jamb, creating a seal that prevents drafts and improves noise reduction.
Testing and Adjustments
- Smooth Opening: Open and close the door repeatedly, checking for smooth, effortless operation. If there's any resistance or binding, adjust the hinges slightly to ensure proper alignment.
- Hinge Adjustment: Use a screwdriver to tighten or loosen the hinge screws on the loose side of the door, adjusting the door to swing freely and evenly.
- Final Touches: Check for gaps between the door and the frame, ensuring a tight fit. If necessary, use wood shims to adjust the gap and improve the seal.
