How to Hang a Door in Your Home: A Step-by-Step DIY Guide

Hanging a door may seem like a daunting task, but with the right tools and some patience, you can achieve a professional result. Whether you’re replacing an old door or installing a new one, this guide will take you through the process, including how to attach hinges, fit the handle and latch, test the door, and apply a quality finish.

Tools and Materials You’ll Need:

• A new door (pre-hung or slab)

• Hinges (typically 2 or 3 per door)

• Screws

• Screwdriver or drill

• Chisel and hammer, or router

• Tape measure

• Pencil

• Level

• Plane (if adjustments are needed)

• Door handle and latch set

• Paint or stain (optional)

• Sandpaper

• Masking tape

• Hinged door wedges or shims

Step 1: Measure and Prepare the Doorway

Before starting, check the doorway’s dimensions to ensure your new door fits. Standard doors in New Zealand are usually 1980mm high and from 710 – 910 wide, but sizes can vary. If needed, trim the door slightly using a plane—be sure to remove small amounts at a time and check the fit frequently.

Step 2: Mark and Attach the Hinges

1. Mark Hinge Positions: Position the door in the frame, ensuring an even gap around the edges (typically 2-3mm). Mark where the hinges will go—usually 150mm from the top and 225mm from the bottom, with a third hinge in the middle for heavier doors.

2. Cut the Hinge Mortises: Using a chisel, carefully cut recesses for the hinges so they sit flush with the door edge.

3. Attach Hinges to the Door: Place the hinges in their recesses, mark the screw holes, and drill small pilot holes before securing the hinges with screws.

4. Attach the Hinges to the Frame: Position the door in place using wedges or shims, then screw the hinges into the door frame.

Step 3: Install the Handle and Latch

1. Mark the Handle Position: Most handles sit around 1000mm from the floor. Use the template provided with your handle set to mark the spindle and latch positions.

2. Drill Holes: Drill a hole through the door for the spindle and a smaller hole for the latch.

3. Fit the Latch and Handle: Insert the latch into the hole, securing it with screws. Attach the handles on both sides, ensuring they turn smoothly.

4. Install the Strike Plate: Close the door to mark where the latch meets the frame. Chisel a small recess for the strike plate and secure it with screws.

Step 4: Test and Adjust

• Open and close the door several times to ensure smooth movement.

• Check for even gaps around the edges.

• If the door sticks, use a plane to trim small amounts from the problem areas.

• Tighten any loose screws.

Step 5: Finishing Touches – Painting or Staining

1. Prepare the Surface: Lightly sand the door to remove any rough patches.

2. Mask Hinges and Handles: Use masking tape to protect hardware from paint.

3. Apply Primer and Paint or Stain: Use a roller or brush to apply an even coat of primer. Once dry, apply two coats of oil based paint or stain, sanding lightly between coats.

4. Let It Dry: Allow the paint or stain to dry fully before closing the door completely.

Tips to Make the Job Easier:

• Use door wedges to hold the door steady while you work.

• Pre-drill holes to prevent splitting the wood when attaching screws.

• Apply a thin layer of beeswax or soap to the latch to help it glide smoothly.

• If painting, remove the door and lay it flat to avoid drips.

With these steps, you’ll have a perfectly hung door that looks great and functions smoothly. Happy DIYing!
