“I would like to thank Jim for being so accommodating on the phone. I was trying to help an elderly friend with her air conditioning and inquired about what materials to use. Without hesitation he said to use rope caulking. Though I was unable to locate this type of caulking (I substituted plumber’s caulking), I appreciate the counsel I received on the phone. In this day and age it is certainly refreshing to hear someone on the other end of the phone that is not a recording! Thanks again.”
