How to tell if uneven flooring panels are defective

“part of me wants to get this old damp warped stuff out too and start new but the other part says f*** it the plywood is your new subfloor!”source ↗
“I keep finding new nicks/chips in the surface, even in low traffic areas like my closet. We’re a no shoe home and I’m pretty neurotic about using felt pads.”source ↗
“Would you replace this chunk, or clean it up and lay the wood over it?”source ↗
“About the wooden floors, i desperately want to save them if possible, however they are not even, in most rooms there is a slope from the halways to the center of the room, and in one bedrom there is a sensible wave in the floor”source ↗
“From what i understood at that point i might be better of just doing new wooden floors from a price and effort perspective, cheapest and easiest would be laminate, but i feel like the apartment would lose a bit of character and value with that.”source ↗
“would it be better just to cover it, I saw some adds for companies that apply a liquid epoxy layer on top, that be the easiest way to do it, i am quite reluctant of putting tiles directly over as that might raise the floor in the halways quite a bit.”source ↗
“pulled up old particle board underlayment to find this mess around the toilet.”source ↗
“This is a 114 yr old house.”source ↗
“What can i expect to find under that section when i remove to replace?”source ↗
“Flooring is cheap and locking mechanism broke. Floor wasn’t flat enough, the whole floor is going to come apart”source ↗

“I feel like the plank quality is bad. $450k home.”source ↗
“Yes it is. As is the pattern and pretty much all LVP”source ↗
“I was assuming that due to these multiple issues I'm pretty much at the point of needing a partial bathroom remodel to replace all the flooring and shower tile.”source ↗
“Do you think it would be possible to just replace the damaged floor portions if I can find matching engineered floor tiles? Does the shower look like it could be regrouted, or should I tear everything out and rebuild it?”source ↗
“The floor is a little messed up, I don't where to start with this but should we consider replacing the flooring or can we do some steps to smoother/save the current flooring before we move in?”source ↗
“I have a finished attic with some very old wood floors. The wood has stains, peeling paint, holes, and gaps of all sizes.”source ↗
“I asked a flooring guy what it would cost to replace the floor and install carpet on top, and he said $12k.”source ↗
“I've thought about tearing out the floor and replacing it myself, but I've also been wondering if there's any way to save this floor?”source ↗
