I contacted several different companies the weekend of January 29th to see if they could install an electronic doggie door. In my inquiries, I mentioned the two companies we were considering for the doggie door purchase and the types of dogs we had. Bill returned my message on Sunday, January 30th. In his initial reply, he said that he had installed many doggie doors. He said that he wanted to discuss with us the type of door we needed so the opener would fit seamlessly, would need to see the door area to see where the electrical outlets were, and examine the current door to see what size door we needed and the type of siding that was currently there. Bill asked whether days, evenings, or weekends were best for us, and asked for our address so that he could come by to discuss our project. In a couple more emails the same evening and the following day, Bill advised us on the type and size human and doggie door we needed. It was obvious he had researched the two doggie door companies I mentioned, and that he was familiar with door installations. He told us when he would be available for an initial visit, which was the upcoming weekend or sooner. Before his initial visit, Bill also called the owner of Solo Pet Doors to further research the doggie door. We agreed that Bill would come by on Saturday afternoon, February 5th. He called before he arrived to say he was on his way. During the first visit, he examined the door area for the doggie door. He asked us what color paint we had in the house so that he could touch up the interior around the door if needed. He advised us to buy a quart of the paint before the installation. He said that he already had the white paint we would need for touch-ups after the install. He had agreed to buy the (human) door for us so that we would not have to worry about transporting it. Before he left, we wrote him a check for the door. Note: Bill does not up-charge for materials. Once I knew when the Solo doggie door would be arriving, I contacted Bill to arrange for installation. It was agreed that Bill would come by on Sunday, February 13th to hang the new door and install the doggie door. He purchased the (human) door the same day as the planned installation, so he arrived about 45 minutes later than agreed. He arrived at our house with the new (human) door and one other worker. The work took about five hours (10:15 AM to 3:00 PM). Though Bill has installed several doggie doors before, this was his first electronic doggie door installation. As promised, Bill touched up all paint around the door and he cleaned up the area to make it look the same as before. Bill also tested out the door to make sure that it worked. Overall, we were very pleased with the end result. It took about a week for the dogs to get used to the new doggie door and it works great. We were especially impressed with the level of research that Bill undertook in preparation for this project. This was unexpected and greatly appreciated. Bill followed up on Thursday, Feb. 17th to see how things were going.
