I know slab flatness has been discussed, but I could not find anything on the forum regarding condos. I have a client claiming the floor is too uneven to lay hardwood and “exceeds industry standards”.
Does anyone have any info about the tolerances that are acceptable for a residential condo? Preferably differences in inches per foot, or over a 6 or 10-foot length. (Also, not the requirement of the flooring manufacturer, but the proper acceptable variance for the slab.)
