Cabinet Door Alignment

Why this matters

Kitchen cabinet doors that don't align (one door sits higher than its neighbor, doors don't close evenly, gaps between doors are inconsistent) are one of the most visible aesthetic complaints. The customer notices every time they look at the cabinet. The fix is rarely complex - usually adjusting the European-style hinges that hold the doors - but most customers don't know how. A handyman who can walk through a kitchen and adjust 12 cabinet doors in 30 minutes makes a meaningful visible improvement; the customer pays a modest for the service and is delighted.

Cabinet hinge types

European concealed hinges are dominant in modern installations and adjust on 3 axes. They're the most adjustable and easiest to align.

European hinge adjustments

A modern Blum or similar hinge has 3 adjustment screws:

Each adjustment is typically a screw at a specific location on the hinge. Reference the hinge manufacturer's documentation; most are similar.

Side adjustment

• Loosen the central screw on the mounting plate (the part attached to the cabinet)
• Slide the door left or right
• Re-tighten

OR

• Turn the side adjustment screw (typically located on the hinge arm)
• Clockwise / counterclockwise adjusts

Depth adjustment

• Turn the depth adjustment screw on the hinge arm
• Clockwise / counterclockwise moves the door in or out

Height adjustment

• Loosen the two mounting screws on the mounting plate (vertical slots)
• Slide the door up or down
• Re-tighten

Tools

• Phillips screwdriver
• Hex driver / Allen wrench set (some hinges use)
• Level (small, 6 to 12 inch)
• Measuring tape
• Pencil

Procedure for a typical kitchen

Step 1: Survey the cabinets

Walk the kitchen with the customer. Identify:

• Which doors are misaligned
• Whether the issue is consistent or random
• Whether doors don't close properly (latch issue) vs misaligned visually
• Whether drawers (separate hardware) are also misaligned

Step 2: Plan the alignment

Decide:

• Are doors generally misaligned in one direction? (Often the case with a wall mount that shifted)
• Are individual doors misaligned? (Loose hinges, age-related shift)
• Do drawers need adjustment too?

Step 3: Adjust one door at a time

For each misaligned door:

1. Open the cabinet
2. Identify which adjustment is needed
3. Make the adjustment (typically 1/16 to 1/8 inch increments)
4. Close the door
5. Check alignment
6. Adjust further if needed

Some doors require multiple adjustments (height + depth, or height + side).

Step 4: Verify consistent gaps

After adjusting all doors, stand back and verify:

• Adjacent doors at the same height
• Equal gaps between adjacent doors
• Doors fully close
• Magnetic catch engages (if equipped)

Make follow-up adjustments to any door that's still off.

Step 5: Tighten loose hinges

If any hinges are loose (screws stripped or hinge wobbling):

• Tighten the visible screws
• For severely loose hinges, replace screws with longer ones
• For damaged screw holes, fill with toothpicks and glue, then re-drive screws
• For severely damaged hinges, replace the hinge

Step 6: Inspect for hardware issues

While adjusting, note:

• Loose pulls or knobs (re-tighten)
• Soft-close hinges not damping (some adjustable; some replacement)
• Spring failures in older spring-loaded hinges (typically replacement)
• Cracked or broken hinges (replacement)

Specific situations

Door sags after adjustment

If a door drops back to its sagged position after adjustment, the hinge screws are stripped. Fix:

• Remove the hinge
• Fill the holes with wood glue and toothpicks or wooden dowels
• Allow to cure
• Re-drive screws

Doors won't close due to spring failure

Some hinges have an internal spring that closes the door. If the spring fails:

• Replace the hinge with the same type
• Match the cup size (the part recessed into the door, typically 26mm or 35mm)
• Match the opening angle (95, 110, or 120 degrees common)

Cabinet door rubs neighboring door

If two adjacent doors rub:

• Adjust both doors' depth (in toward cabinet)
• Adjust the side position to widen the gap between them

Drawer alignment

Drawers use different hardware (typically drawer slides):

• Most slides have lateral adjustment
• Loosen mounting screws; reposition; tighten
• For older slides without adjustment, may need replacement

Replacement of failed hinges

For a hinge that needs replacement:

1. Open the cabinet
2. Remove the door
3. Unscrew the failed hinge from the door
4. Unscrew the mounting plate from the cabinet
5. Install the new hinge on the door (match cup size and overlay)
6. Install the new mounting plate on the cabinet
7. Reinstall the door
8. Adjust for alignment

European hinges are sized by:

• Cup diameter (26mm or 35mm most common)
• Overlay (door's overlap on the cabinet; typical 1/2 inch or specific to the door)
• Opening angle (90, 95, 110, 120, 170 degrees)

Replacement hinges should match the originals. Mismatch produces a door that doesn't open or close correctly.

Customer expectations

Set expectations:

• "Cabinet alignment is largely about hinges; the cabinet boxes themselves don't usually move"
• "Most doors can be aligned within minutes; some need replacement hinges"
• "Cabinet doors won't be perfectly aligned forever; minor adjustment every year or two is typical"

When alignment isn't possible

Some situations require more than adjustment:

• Cabinet box is twisted or damaged: structural repair
• Doors themselves are warped: replacement
• Hinges are obsolete and not replaceable in kind: more invasive repair or full hinge replacement

In these cases, the alignment work won't produce satisfactory results. Communicate honestly.
