Hello everyone. I appreciate your time and expertise in helping me with this problem. I have recently had some LVT Smartcore Ultra made by Coretec installed in my kitchen and foyer. A few weeks after installation there began to be a crackling noise when stepping on the seams. I have contacted the installer, but he hasn't returned my texts as of yet. I would like some input from you as to whether I am correct in assuming what the issue is. I can upload a video, but I don't think it's necessary to understand what the crunching sound is like as there have been uploads in the past which very similar to what I have going on. The manufacturer's instructions clearly state that a 1/4" gap between the walls and the planks is required. I believe that the installer failed to leave enough space on the perimeter and now the floor has expanded and is causing the seams to bunch. Please review the following photos and help me confirm. I only pulled a small portion of the baseboard up and took one photo beside the pulled out stove. I imagine the rest of the perimeter is pretty much the same. Thank you for you time.
