The subfloor is what they call the base of any floor, whether it’s tile or wood, that will hold most of the weight. It’s not meant to be pretty like laminate or vinyl ground coverings, but if it fails (which is unlikely) then you’ll see a lot more of the flooring.

Removing the old subfloor is not a difficult task, but it does require some care and attention. Here’s how to remove your kitchen cabinets’ subfloor:

  1. Start by removing all of the doors and drawer fronts from your cabinets. If possible, remove the hardware as well. Set these aside in a safe place.
  2. Next, use a putty knife or other thin tool to pry off the trim pieces that cover the edges of the cabinet boxes. Be careful not to damage the trim as you remove it.
  3. With the trim removed, you should now be able to see the screws that attach the cabinets to the wall. Remove these screws, and then carefully lower the cabinets down from the wall.
  4. Once the cabinets are removed, take a look at the condition of the subfloor underneath. If it is in good condition, you can simply install new cabinets on top of it. However, if the subfloor is damaged or otherwise not in good condition, you will need to replace it.
  5. To remove the old subfloor, start by using a utility knife to score around the perimeter of the area where the subfloor needs to be removed.
  6. Next, use a chisel and hammer to remove the section of the subfloor that you’ve scored. Be sure to work carefully so that you don’t damage the surrounding area.
  7. Once the old subfloor is removed, take a look at the condition of the floor joists underneath. If they are in good condition, you can simply install the new subfloor over them. However, if the floor joists are damaged or otherwise not in good condition, you will need to replace them as well.
  8. To install the new subfloor, start by spreading a layer of construction adhesive on the floor joists.
  9. Next, lay down the first piece of subflooring and nail it into place. Be sure to use nails that are long enough to penetrate through the subfloor and into the floor joists below.
  10. Repeat this process until the entire area is covered with new subfloor.
  11. Once the new subfloor is in place, you can then install new cabinets on top of it.
  12. Start by attaching the new cabinet boxes to the wall using the screws that you removed earlier.
  13. Next, install the doors and drawer fronts onto the cabinets. If possible, reuse the old hardware. Otherwise, you can purchase new hardware to match your cabinets.
  14. Finally, reattach the trim pieces to the edges of the cabinet boxes.
  15. That’s it! Your kitchen cabinets’ subfloor has now been replaced.

Does subfloor go under cabinets?

Yes, the subfloor does go under the cabinets. The cabinets are attached to the subfloor with screws and/or nails. If the cabinets are not level, it is because the subfloor is not level. You can level the cabinets by shimming them with washers or strips of wood. If the subfloor is uneven, you may need to level it before installing the cabinets.

Is it hard to remove subfloor?

It depends on how the subfloor is installed and what type of flooring is being removed. If the subfloor is glued down, it may be difficult to remove. If the subfloor is nailed down, it may be easier to remove. If the flooring is a laminate or engineered wood, it may be easier to remove than if the flooring is solid hardwood.
