How to Install or Replace Kitchen Cabinet Doors

Kitchen cabinet doors take the visual and functional hit of daily use—they swing open hundreds of times a year, catch grease and moisture, and eventually stick, sag, or crack. Replacing them is one of the highest-impact upgrades you can make without a full cabinet tear-out. The work is straightforward: each door hangs from two hinges that bolt directly to the cabinet frame, so you can remove one and install another in its place. Done well, new doors transform how a kitchen looks and feels. Done poorly, they'll bind, slam, or hang crooked. The difference between the two is patience with measurement and adjustment—there's no rush once a door is mounted.

1. Locate the Hinge Points. Swing the cabinet door open to 90 degrees. Most kitchen cabinets use two hinges—one about 3 inches from the top, one about 3 inches from the bottom. Look at the hinge bracket bolted to the inside face of the cabinet frame (not the door itself). This is where your attachment points are. Mark the screw locations with a pencil so you can reference them later.
2. Unbolt and Lift Away. Use a cordless drill or screwdriver to remove all bolts from both hinges. Most hinges use 1/2-inch or 5/8-inch bolts with nuts on the back. Have someone hold the door level as you remove the last bolts, or support it yourself with your body—don't let it drop or twist as you release it. Lift the door straight out and set it aside flat on a work surface.
3. Verify Dimensions Match. Before installing, measure the opening width and height. Check that your new door fits: it should leave about 1/8 inch of clearance on all sides (top, bottom, left, right) so it swings freely without binding. If the new door is significantly different in size, stop here and verify you have the correct replacement—cabinet doors are made to very specific dimensions.
4. Check Frame Integrity. While the door is off, check the hinge mounting points on the cabinet frame. Look for cracked wood, stripped bolt holes, or bent hinge brackets. If the wood is cracked around a bolt hole, you may need to fill it with wooden toothpicks and wood glue, or drill a new hole slightly offset. If the hinge bracket is bent, replace it. Make sure the cabinet frame itself isn't bowed or twisted—if it is, you may need to reinforce the frame before hanging a new door.
5. Center and Shim Door. Lean the new door into the opening so it rests against the cabinet frame. Start at the top hinge. Slide a shim (a thin wooden wedge) between the door and the frame on the latch side (the side opposite the hinges). Add shims as needed so the door sits centered in the opening with equal clearance on all sides. The door should not touch the frame anywhere except at the hinges. Have someone hold it steady while you work, or prop it with your body.
6. Secure Top Hinge First. With the door held in position by shims, insert the bolts through the top hinge bracket (the one on the cabinet frame) and through the corresponding mounting holes on the door's hinge plate. Finger-tighten the bolts and nuts—do not fully tighten yet. The door should still be moveable for adjustment.
7. Square the Top Edge. Step back and look at the top of the door. It should sit centered with even clearance between the door and the frame on both sides. If the top is off-center, loosen the top hinge bolts slightly, adjust your shims, and re-tighten. Once the top is square, insert and finger-tighten the bolts for the bottom hinge in the same way.
8. Secure All Bolts Firmly. Using a wrench or socket, tighten all four bolts (two per hinge) firmly but without cranking. You want the door held solid to the frame, but over-tightening can strip threads or bend the hinge bracket. Tighten in a cross pattern: top-left, bottom-right, top-right, bottom-left. This prevents the hinge from twisting.
9. Test Full Range of Motion. Slowly open and close the door through its full range of motion. Listen for rubbing sounds and watch for places where the door touches the frame. If it binds at the top, bottom, or edges, the door is out of square or your shims are in the wrong place. Mark the bind spot with a pencil so you can see it clearly.
10. Fine-Tune Until Perfect. If the door binds, loosen the hinge bolts on the side toward which the door is rubbing, remove or adjust shims, then re-tighten. If the door gaps unevenly (wider at the top than the bottom, for instance), loosen the top hinge bolts and shift the top of the door slightly in the direction you want it to move, using additional shims if needed. Make small adjustments—an extra shim thickness of 1/16 inch makes a visible difference.
11. Add Handle and Test Latch. Once the door hangs square with good clearance all around, mark the hole locations for the door handle, drill as needed, and bolt or screw the handle in place. Close the door gently and make sure the latch engages smoothly without binding. The door should swing closed under its own weight and latch without forcing.
12. Remove Shims and Polish. Once the door is fully adjusted and secured, you can remove the shims—the bolts are now holding the door in place. Carefully pry the shims out from behind the door. Clean up any sawdust or debris around the cabinet, and remove any pencil marks with a magic eraser or appropriate cleaner for your door finish.
