We recently went through a main floor reno with a reputable contractor/design firm. They removed all our old flooring on the main floor, laid new sub-flooring and Armstrong LVP. There has been nothing but issues since. As you can see by the photos, some of the flooring is bubbling, some boards are showing bumps underneath and no matter how much I clean them, as soon as they are swept and then mopped/dried prints show up. They have tried to replace the bubbled/warped boards at least four times and this still occurs. They now blame our house and say it's due to shifting or the floor joists, even though this is the only area of the main floor this is happening. They don't even speak to me about the bumps and will probably say the same thing. But are saying I will need to pay them more money to rip out the flooring to check the joists/redo, etc.. For the foot prints, I've tried every cleaning solution, water and vinegar, dawn dish soap and water, special LVP cleaner, etc.. the last suggestion from the supplier is Armstrong Once N' Done. Didn't work. We walk in socks or slippers and a foot print will still show through socks. My questions are, can they be defective as we are not able to remove the prints and can't even walk on the floor without it looking like the photos within a minute of walking on them after washing and drying them. I am aware residue form other cleaners may be leaving a film and causing the prints, but was told the Once N' Done would help remove any film or residue. It didn't. Also is the warping/bubbling a joint issue?? And wondering about the bumps. I've read Vinyl will show any bit of dust from the subfloor. Could shifting in the flooring (hence shifting of the subflooring) cause this? Some areas look like the nails or screws from the subfloor are starting to 'pop up' or the floor boards not being level. I can't tell.
