Overview

This task covers unscrewing old knobs, pulls, or hinges from cabinet doors and drawers and installing new ones in their place, including drilling new holes when the replacement hardware has a different screw spacing than the original. It's a purely cosmetic upgrade well suited to a first-time DIYer with basic hand tools, and it's one of the fastest, cheapest ways to refresh the look of a kitchen, bathroom, or piece of furniture. Most single-cabinet swaps take just a few minutes once you've measured correctly; a full kitchen can be done in an afternoon.

Tools & materials

  • Screwdriver or cordless drill/driver
  • Tape measure or ruler
  • Pencil
  • Painter's tape
  • Center punch or awl
  • Drill and bits sized to the new screws
  • Wood filler and a putty knife (only if old hole spacing won't be reused)
  • New knobs, pulls, or hinges
  • Cabinet hardware jig or template (optional, helpful for multiple doors)

Steps

  1. Remove one door or drawer at a time and unscrew the existing knob, pull, or hinge from the back.
  2. Measure the hole spacing ("center-to-center") of the old hardware and compare it to the new hardware's spacing, listed on its packaging.
  3. If the spacing matches, you can reuse the existing holes exactly - skip straight to installing the new hardware.
  4. If the spacing differs, decide on the new hole locations using a tape measure, a hardware jig, or by holding the new pull in place and marking with a pencil.
  5. Stick a strip of painter's tape over the marked spot on painted or laminate surfaces to keep the drill bit from skating across the finish.
  6. Use a center punch or awl to dent the surface at each mark so the drill bit starts exactly where you want it instead of wandering.
  7. Drill the new holes using a bit sized to the new screws, backing up thin panels with a scrap block to prevent splintering on the exit side.
  8. If the old holes will now be exposed, fill them with wood filler, let it dry, sand smooth, and touch up with matching paint or stain before installing the new hardware.
  9. Insert the new knob, pull, or hinge from the front (or mount the hinge per its instructions) and hand-thread the mounting screws from the back.
  10. Tighten the screws snugly with a screwdriver or drill - snug, not overtightened, so you don't strip the wood or crack a laminate face.
  11. Reinstall the door or drawer if it was removed, then open and close it to check that it swings or slides freely and sits flush.
  12. Repeat for each remaining door and drawer, using the first one as a measuring reference to keep placement consistent throughout.

Safety warnings

  • Wear eye protection when drilling, especially overhead on wall cabinets.
  • If the cabinet or door has painted wood from before 1978 and you'll be sanding or scraping around an old hole to fill it, use wet-sanding or a HEPA vacuum and avoid dry-sanding to limit lead dust exposure. This same caution applies when drilling new holes in pre-1978 painted cabinet doors — drill at a slower speed and wipe away paint chips or dust with a damp cloth rather than blowing or brushing them clear.
  • Keep fingers clear of the drill bit's exit path and use a backing block so the bit doesn't punch through unexpectedly.
  • If you're using an oil-based or solvent-based wood filler, stain, or paint for touch-ups, open a window or run a fan for ventilation, and avoid extended close-up breathing of fumes in a small kitchen or bathroom.

When to call a pro

  • The doors use hidden European-style hinges that require boring large concealed cups with a specialty jig or Forstner bit you don't have.
  • Cabinet doors are warped, sagging, or misaligned in ways a hardware swap alone won't fix - that's a door or cabinet repair issue, not a hardware issue.
  • You're refacing or replacing many doors at once and want a designer to help coordinate finishes and hole layouts across an entire kitchen.

Cost estimate

$2-$15 per knob or pull and $5-$25 per hinge pair, so a full kitchen of 20-30 pieces typically runs $75-$400 depending on style and finish; add a $10-$20 hardware jig if doing many doors.
