Why don't you call the installers and have them remove the cabinets?

Thanks Geoffrey, but that would defeat the purpose! I paid a ton for them. Do not want to pay a ton to get them off the walls!

I called them yesterday, and they assured me they only use screws, but maybe time has glued them to the walls? We just cant get them to budge!

Sure there are not screws hidden behind other wood?

I just took down kitchen cabinets. Check for screws attaching the from face frames together, which may be under hinges. Also look very carefully for screws into the wall, sometimes they are hard to see because of shelves, other hardware, or odd location. Look all over on the outside of the cabinet too, especially the bottom. Then try to gently remove it again, noting which sections seem to be stubborn, and recheck for screws there.

It's very frustrating, but with some patience you should be able to get them out if it's only screws.

Good luck!

Do you know if they used a rail mounting system on the wall? I've seen them used on some closet systems and they're similar to Ikea cabinets.
If you're sure you've removed all the screws, try lifting the cabinets to see if they're hooked on a rail.

Thank you so much! You are all my new best friends! I have sent the link to this thread to DH, and he will appreciate your input! I promise to update if or not we were able to remove the cabinets!
