Hanging a new internal door may seem like a challenging task, but with the right tools and a step-by-step approach, you can achieve a professional-looking result. Whether you are replacing an old door or installing one in a new frame, this guide will walk you through the process to ensure a secure and well-fitted door.
Tools and Materials You’ll Need
- New internal door
- Hinges (typically 2 per door internal, 3-4 for heavy external/entry doors)
- Screws
- Screwdriver or drill
- Chisel
- Hammer
- Spade bit
- Measuring tape
- Pencil
- Spirit level
- Plane (for trimming if needed)
- Sandpaper
- Door handles and latch set
- Wood filler (if required)
- Paint or varnish
Step 1: Measure the Door Frame
Before purchasing a new door, measure the height, width, and thickness of the existing door frame. If the door is slightly too big, you may need to trim it down for a perfect fit. Allow a small clearance gap (about 2-3mm) on all sides to ensure smooth operation.
Step 2: Trim the Door (If Needed)
If the door is too large, use a plane or circular saw to trim the edges carefully. Sand the edges smooth to prevent splinters. Always check the fit within the frame before proceeding to the next step.
Tip: ensure you have around 4-6mm gap on either side and top of the door and about 7-10mm on the bottom.
Step 3: Mark and Cut Hinge Positions
- Place the new door into the frame and mark where the hinges will be positioned. Typically, one hinge is placed 7 inches from the top, another 11 inches from the bottom. Heavy doors will require a third hinge about 50mm under the top hinge, add a 4th in the middle of the door (if required)
- Use a chisel and hammer to create shallow recesses (mortices) in the door edge where the hinges will sit. The depth should match the thickness of the hinge plate.
- Screw the hinges into the recesses, ensuring they sit flush with the door edge.
Step 4: Attach the Door to the Frame
- With the help of another person (or use of packers) position the door within the frame.
- Align the hinges with the corresponding hinge cutouts on the frame and screw them in securely.
- Check that the door opens and closes smoothly. If it sticks, minor adjustments may be necessary.
Step 5: Install the Latch, Handle, and Strike Plate
- Measure and mark the handle height (usually around 900mm from the floor).
- Drill a hole for the latch mechanism and another for the spindle of the handle.
- Insert the latch and secure it with screws, followed by the door handle.
- Mark out where the latch hits the frame, drill out a recess with a spade bit on the frame, and recess the strike plate.
- Test the handle operation and adjust if needed.
Step 6: Final Adjustments and Finishing Touches
- If gaps are uneven, remove the door and trim where necessary.
- Fill any gaps or screw holes with wood filler, then sand smooth.
- If required, paint or varnish the door for a polished finish.
Conclusion
Hanging new doors requires patience and precision, but by following these steps, you can achieve a secure and professional result. Always take your time with measurements and hinge placements to ensure smooth operation. With the right preparation, your new door will be both functional and aesthetically pleasing for years to come.
