Thank you for the link. The problem with waiting is that the door often won't slide more than a 1/4 of the way open and you have to squeeze through. We use the door frequently on a daily basis to let the dog in and out, water the plants and do yard work etc. I certainly don't want to have to leave the house and walk around to the back of the house every time I want to go in the yard. We’re planning on sending him a written letter asking him to repair the door, but today he told us he closed his P.O. Box so now we don’t know where to send it; we have no other address for him. Is he required to give us an address or something?
