We were forced to replace our original bay window in the summer of 2007, and despite a questionable reputation, we called Jack's Wholesale Windows. Boy am I glad we did. We had five estimates on the work and by far the Jack's salesperson, Denny, was the most knowledgeable and professional of all the salespeople. While their estimate wasn't the lowest, primarily due to the quality, Denny matched the lowest quote (on a clearly inferior window) just to get our business. That was just the first step of a great process. Our window was custom made and the installation was set, and surprisingly the installers were on time and very efficient. They even went above and beyond to do some extra trim work to make sure it looked good that most of the other companies had balked at. As promised, the new bay not only looked great, but it did a wonderful job of temperature control, essentially giving us our living room back. If this had been the end of it, I doubt that I would have written this. But the story continues about a year later, about a month ago this summer. Due to the heavy rains we had this spring, we developed a leak in the bay. I thought it was simply a matter of needed to be caulked, so we tried that a couple of times to no avail. Thinking that I was going to have to pay for a service call, I dialed up Jack's service line and requested a visit. I was surprised that they insisted to get someone here the very next morning, and when they showed up, they pointed out the problem with our soffit. Not their problem, more of a problem with the gutter system, but they again insisted on trying something to make it right. They custom installed a piece of metal designed to protect the roof line and redirect the water, all in about 20 minutes. When finished, they refused payment and told me to call if any more water should come in, as well as scolding me for not calling them sooner. I have no idea where any questions about their products or service have come from. The entire process has been fantastic, from sales, installation, and to service. I could not be happier and will absolutely call them for any future window work. Highly recommended!
