How To Install Concealed Door Hinges?

concealed door hinges, sometimes called invisible or hidden hinges, are designed to sit flush within the door and frame, providing a sleek, modern appearance without visible hardware. Installation requires careful measuring and precision, but with the right approach, you can achieve professional results.

Tools and Materials Needed

• Concealed hinges (check weight capacity for your door)

• Drill with hole saw or Forstner bit

• Chisel and hammer

• Measuring tape and pencil

• Screwdriver

• Screws (often included with hinge set)

• Level

Step 1: Mark the Hinge Placement

• Decide how many hinges you need: typically two for interior doors, three for taller or heavier doors.

• Mark the hinge locations on the door edge and frame, usually 7–10 inches from the top and bottom.

• Use a level to ensure alignment between door and frame marks.

Step 2: Cut Recesses for the Hinges

• Using a drill with the correct size bit, bore the recess where the hinge body will sit.

• Depth must match hinge specifications so the hinge sits flush.

• Clean up the recess with a chisel for precise edges.

Step 3: Attach Hinges to the Door

• Insert the hinge into the recess and secure with screws.

• Check that the hinge body fits snugly without wobbling.

• Repeat for each hinge.

Step 4: Transfer Marks to the Frame

• With hinges attached, position the door in the frame.

• Mark corresponding recess locations on the frame.

• Drill and chisel recesses just as you did on the door.

Step 5: Mount the Door

• Insert hinge bodies into the frame recesses.

• Secure with screws, starting loosely to allow minor adjustments.

• Tighten once you confirm the door sits evenly.

Step 6: Adjust the Hinges

• Many concealed hinges allow 3D adjustments (up, down, in/out, side-to-side).

• Use a screwdriver to fine-tune until the door opens and closes smoothly, with even gaps along the frame.

Tips for Success

• Always follow the hinge manufacturer’s specifications for recess depth and screw placement.

• Pre-drill pilot holes for screws to prevent splitting.

• Use strong hinges rated for the door’s weight.

• Work slowly—accuracy is more important than speed.

Conclusion

Installing concealed door hinges requires careful measuring, drilling, and adjustment, but the results are worth it: a clean, modern doorway with no visible hardware. With the right tools and patience, you can achieve a professional finish and long-lasting performance.
