I did an inspection for a young couple in May on new construction. Come winter they saw that the hardwood floors were separating substantially. The builder had the flooring guy come out and he told them to turn up the humidifier which they did. Apparently this helped the flooring problem but they have the humidity too high where its condensing on windows and causing paint on the interior windows to peal and mold. Is the flooring guy telling them to turn up the humidity on the furnaces a dodge and that they installed the floor wrong with too much moisture? My advice was to turn the humidifiers off and and that the condition of the floor should not be determined by the humidifiers. I also informed them that humidifiers, in my experience, do more harm than good to the home.
