Types of interior doors: flush vs rebated

• Flush (standard) doors – flat edges, sits fully within the frame, hung on butt hinges
• Rebated (lipped) doors – stepped edge that overlaps the frame, often uses different hinge positioning

Step 1: Measure the frame & door (get the right clearance)

Measure the frame opening at multiple points (top, middle, bottom) to check if it’s square. A perfectly fitted door needs small, consistent gaps.

• Side gaps: aim for even spacing along the hinge and latch side
• Top gap: keep it consistent across the header
• Bottom gap: allow clearance for flooring, rugs and airflow

Step 2: Trim, plane & sand for clearance

If your door is slightly oversized, trim or plane small amounts at a time. A workbench helps keep the door stable while you work. After trimming, smooth the edges to avoid splinters and improve paint adhesion.

• Trim/plane gradually and test fit often
• Sand edges for a clean finish
• Seal or paint raw edges before fitting in humid rooms

Finish edges cleanly with the 12V Cordless Detail Sander and support the door on a stable workbench.

Step 3: Mark & cut hinge recesses

Correct hinge recess depth is crucial. If hinges don’t sit flush, the door won’t close cleanly and may bind on the frame.

• Mark hinge positions on the door (top and bottom, plus a third hinge for heavy doors)
• Transfer marks to the frame
• Outline each hinge leaf precisely
• Cut a shallow recess to match hinge thickness

Step 4: Hang the door & align gaps

Use wedges/spacers to hold the door at the correct height in the frame. Attach hinges to the frame, then check for even gaps and a smooth swing.

• Support the door with wedges so it can’t drop while fastening
• Drill pilot holes to prevent splitting
• Screw hinges firmly and check movement
• Make small adjustments if the door rubs

Step 5: Install handle, latch & strike plate

Mark the handle height, drill the latch hole, then fit the latch and handles. Finally, align and screw the strike plate so the latch closes smoothly.

• Mark handle position (keep consistent across your home)
• Drill latch hole and recess
• Fit latch, handles and screws
• Install strike plate and test closing

Pro tips for hanging an interior door

• Check squareness first: if the frame is out of square, plan your trimming accordingly
• Use longer screws in the top hinge: improves durability and reduces sag
• Work on a stable surface: a workbench makes cutting and sanding safer and more accurate
• Seal edges for humid rooms: reduces swelling and sticking
• Take your time: careful measuring and small adjustments beat rushing every time
