We have a four year old two story house with a 3/4 inch plywood subfloor upstairs covered by carpet. The plywood is “bumpy” (due to water damage during construction) in many areas to the point where it is noticeable while walking over the carpeted floor. My builder told me that the carpet would compensate for the plywood’s condition, but it does not. The home warranty allows for 1/4 inch variation in floor height. What is considered acceptable sub-floor construction? Should I be able to feel any irregularities in the sub floor? Is there any solution besides ripping up the bad sub floor pieces? Also, part of the irregularity I believe is due to a couple of bowed floor joists. How do I fix those?
