We did the whole house and they were fantastic! The demo of the old windows and install of the new ones took only a day. They cleaned up very well when they were done and made sure we were happy. I asked them to come back a week later and check on something, and they did! They were just great. They stand by their product and your satisfaction is their top priority. They were recommend by two other people I know and I am glad I went with them. Their pricing was good and their installation fee was totally in line with having 4-5 people working at once. Glad I went with them.
K&J Windows was fantastic from start to finish. The quoting process was clear, installation was right on schedule, and the team was professional—quick, efficient, and cleaned up perfectly. The owner personally answered all my questions, and when a small cosmetic issue came up (the windows themselves worked perfectly), they listened and sent someone out promptly to fix it, no hassle at all. It’s rare to find a company that cares so much about the entire experience—and their price was the best around. Highly recommend them and would hire again with zero hesitation.
K&J windows did a great job quoting and measuring for a new fiberglass double entry door. Shawn was a great point of contact walking me through the options, install process, and coordinating the quotes. Maxwell came out to measure for the install - he answered all of my questions with professionalism and arrived promptly. I ultimately went another route due to my narrow timeframe for getting the job done (my own fault), but I wanted to leave a glowing review for the K&J team - they will take great care of you!
We had an excellent experience with getting a new front door installed this past spring! Our old door was not a standard size and other folks I had out for quotes weren't nearly as knowledgeable and helpful as our K&J salesman Tony Liethen. He really took his time at our initial appointment to make sure they'd be able to help us out, and it did take the installers probably a good deal longer than normal due to this very old house and door. Even though the install took quite a while, there was no additional cost or quote adjustment after the first quote.The installers did forget one screw and forgot to adjust the threshold, but K&J sent someone right out to get those things tidied up for us and were very professional and nice about all of it! Thank you so much for helping these new homeowners and for your patience and professionalism!
K&J did a fabulous job updating our windows. The windows themselves were the Amsco middle range product, that we chose based on budget and quality - they are great. Clean lines, work well, beautiful design. I was concerned it would make the house darker because they have built in heat and light reflecting, but it made no change in the amount of light coming in, and actually made it brighter because we do not have to use sunscreens anymore. The installers were extremely professional, had over 10 years of experience in the industry, were on time every day, worked quickly and efficiently, cleaned up after themselves, and did a fabulous job. We are thrilled with the change in our home after the windows were installed. It's like a new house! From initially working with the salesman (Tony), to the follow up questions and changes we made, to the installation, and follow up afterward, it was an incredibly smooth experience. And they quickly responded to my questions and changes I wanted to make from our initial bid. I would HIGHLY recommend K&J, I found them using on online search because I wanted to use a local small business, and am so glad I found them!Before and after pictures below. It's like I live in a magazine now!We had K&J out again at our house purchased recently (2023), they again did a fabulous job. Jose and Jacob did the install and were efficient, clean, and thorough. Everything looks amazing, the caulking was done really well to prevent leaks - a problem we were having with our previous windows. We went with a product between mid- and high-grade. They are crystal clear and keep the heat out without having to use sunscreens. I love how it gives better visibility and lets more light in. The price point was also excellent, with a discount given for doing the whole house. Thanks again, K&J, we'll recommend you to all our friends and family looking for windows.
