How to Hang a Door

Tools and Materials

Before You Start

• Measure the opening at three points (top, middle, bottom) for width, and both sides for height — use the smallest measurements
• Check the frame is plumb and square using a spirit level and tape diagonal measurements
• If replacing a door, remove the old door and check hinge recesses — you may be able to reuse them
• Allow the new door to acclimatise indoors for 48 hours before fitting to prevent warping
• Prime or seal all six faces of the door (including top and bottom edges) to prevent moisture absorption

Step-by-Step Installation

1. Step 1 — Measure and mark. Measure the opening and transfer dimensions to the door, allowing for gaps (2-3 mm sides and top, 8-10 mm bottom). Mark the cutting lines clearly.
2. Step 2 — Trim the door to fit. Trim with a plane for small amounts or a circular saw for larger cuts. Score the cut line with a knife first. Test-fit the door in the opening with packers at the bottom.
3. Step 3 — Mark hinge positions. With the door wedged in the opening at the correct height, mark the hinge positions on both the door and the frame simultaneously. Top hinge: 150 mm from top. Bottom hinge: 225 mm from bottom.
4. Step 4 — Cut hinge recesses. Using a sharp chisel and mallet, cut the hinge recesses to the exact depth of the hinge leaf (typically 2-3 mm). Score the outline with a knife first, then chisel out the waste. The hinge should sit flush with the surface.
5. Step 5 — Fit hinges to the door. Screw the hinges to the door first, using pilot holes to prevent splitting. Check that the hinges sit flat and flush in their recesses.
6. Step 6 — Hang the door. With a helper or door lifter, position the door in the frame and drive one screw into each hinge on the frame side. Check the gaps and swing. Adjust if needed, then drive the remaining screws.
7. Step 7 — Fit the latch. Mark the latch position (typically at handle height, 1000 mm from the floor). Drill the latch bore hole through the edge, then chisel a recess for the faceplate. Insert the latch and screw the faceplate flush.
8. Step 8 — Fit handles and strike plate. Drill the spindle hole through the face of the door. Fit the handles on both sides. Close the door and mark where the latch meets the frame. Chisel a recess for the strike plate and fit it with screws.
9. Step 9 — Final adjustments. Check the door opens, closes, and latches smoothly. Adjust hinges or plane edges as needed. Apply a final coat of paint or stain to any exposed timber.

Common Mistakes

• Not checking the frame is square — a twisted frame will cause the door to bind or swing open
• Cutting hinge recesses too deep — the door will bind on the hinge side; pack with card if too deep
• Splitting the timber by not drilling pilot holes — always pre-drill, especially near edges
• Removing too much from one edge — trim equally from both sides where possible
• Not sealing the top and bottom edges — moisture ingress causes warping
