I've had my wood floors for a year now. A month after the installation I noticed a cracking noise in certain parts of the floor when I walked on it... I've used the baby powder on the floors... and the home depot guys have come out several times to help allieviate the problem, but no the cracking noise is on all the floor. It just started a month ago... so when the temperature got hot... its really loud... especially at 5:30am!!!! What can I do at this point? Thank for your help in advance
