We had (5) Citadel sliding doors with side panels installed in a new house in 1999. All of these doors leak because of rotting wood underneath the sill. One door was replaced by Peachtree in 2002, and that one leaks again. After numerous conversations and e-mails to and from Lillian Johnson, I finally talked to a manager who told me that it had to be an installers problem because their doors do not have problems with rotting wood if they are installed properly! Bull! All these doors were professionally installed by a competant installer. They have a manufacturers defect but the company won't say that. I am considering legal action, but am looking for others who have similar problems.
