I accompanied my mother to Home Depot to purchase an exterior door for her home. We had many questions regarding time frame, cost, hardware, etc. There were may Home Depot reps available to answer our questions. We left with the number for a contractor who would install the door for us. He showed up promptly a week later and gave us a quote that was within our budget. The contractor assisted us with picking the hardware and even installed the door 3 weeks ahead of schedule. The price may have been a bit more than buying it from somewhere else, but the warranty and quality of service was well worth the extra cost.
