I just had new vinyl plank floor put down. I hired a local professional to do the work. The floor looks great, but...whenever we walk on certain spots, the floor pops. The popping is the result of the floor sticking to the old adhesive. Honestly, it’s driving me crazy. When the work was being done, I noticed there was still some leftover glue still on the floor, but I assumed the professional installer knew what he was doing. We paid the installer to remove and dispose of the old flooring and install the new vinyl plank. My question is should the installer have removed the glue or put something down before installing the new vinyl planks? The job is done and it’s about 750 square feet. I hate to go back to the installer, but I’m having a hard time dealing with all of the popping, particularly in the morning. Should he have have done something to deal with the old glue before putting down the new floor? If so, would it be reasonable to expect him to come back out and fix the problem? Thanks ahead for the input.
