Calvin came out and did some tedious and meticulous work for me this week. He and his counterpart built, from scratch, 3 screens for very old warped windows. They had to make multiple adjustments to the screens as the window frames were not even. Nevertheless, they got the job done and their work reflects their commitment to quality. Also, Calvin installed for me a window air conditioning unit in an old window that is really not designed to hold such a machine. However, he is creative and figured out a way to install the unit as to make sure it is secure and that the window itself was presentable upon completion and protected from the elements. What was supposed to be a short job turned into nearly an all day affair, due to the nature of the work and the house being very old. Nevertheless, Calvin negotiated a very reasonable and agreeable payment for such an incredible amount of work. I was pleased with his commitment to quality and customer service. Also, a plus, while at Home Depot obtaining the requisite supplies, he had a store manager contact me via phone and read of the list of purchases and I was able to pay for them directly over the phone, saving the trouble of factoring supply reimbursement into Calvin's bill.
