Our resilent [vinyl] floor is to be replaced under a manufacturers warrenty, but the warranty does not cover replacing a subfloor [1/4 plywood, whatever]. The warranty covers other labor and materials. The flooring retailer whom we have contacted to do the work states that our subfloor must be removed, that they do not do such work and it is not covered by the manufacturer's warranty. They have advised us to get a contractor to make the floor read for the vinyl replacement. Our dishwasher was replaced and we were told that it had a leak. The seven year old vinyl began showing stains near the washer which we assume was the cause of the stains. The people who say we must replace the have not cut into the old vinly nor made a moisture test. They have walked over it stating that it seems squashy, etc. The original people who did the work are out of business. Should we accept the conclusion about the need for replacing plywood subfloor, or would you recommend that we contact another vinyl retailer?
