Honestly, I could not have been more pleased with my decision to go with K&J. They were not the first nor the last bid I recieved, but they were by far the company that made me feel the most at ease with the project I wanted done. I replaced all 11 (50+ year old) windows in my home and I am so pleased with the quality of the window and the work, and K&J was able to keep the overall asthetic of my old ranch home while giving it a HUGE upgrade. Cody was the best. He gave me an itemized and specific quote within 24 hours of his visit to my house. He responded to my emails when he was on vacation and even responded to an email I sent significantly after business hours the night before the install because I was worried about a few things - all of which he addressed and set my mind at ease. The professionalism and low pressure sales that was displayed by K&J was so vastly different than the big commerical orange company I had recieved my original quote from - which not to mention was close to 25% more than K&Js quote for the same project with a far lower quality window. Nick and all others on the instasll crew were also great. Everyone was on time, professional, and their customer service has been nothing short of awesome thus far. I RARELY write reviews on yelp, only for the very very best and the very very worst, and K&J is definitely the former. I used yelp to find K&J and the 5-star ratings are well deserved. I will be recommending them to everyone I know. read more

Had an amazing experience with my sales rep. who was very knowledgeable and responsive. I had several quotes from different companies and choose K&J for their willingness to work with me to find product to meet my needs and their knowledge of the product. I highly recommend this company for your window and door needs. read more

A great company with a very personable, friendly and knowledgeable owner. Darin came to our house and advised us on what would look great for our structure of house. We chose windows and doors together, and felt confident before during and after the project. Any issues over time that came up with a complete house Window/Door remodel were promptly taken care of with the best of customer service and support. Communication is top notch and i would recommend you do your project with Darrin and K & J Windows. read more

Great service great experience super impressed with the job done had 7 windows and 1 sliding glass door done they helped through the whole process great customer service. Would recommend to anyone!! read more

We selected KJ to bid our windows and sliding doors. The quality and price of the windows we purchased were great. They completed our fairly large job in one day. There were a couple of minor communication issues during install, but were quickly corrected. The reason we didn't give all five stars is because the crew left broken glass and a lot of plastic caps that were cut off the caulking tubes in our front rock landscape. It's been 8 months and we are still finding plastic caps and glass bits. But other than that, I will definitely use them again and we've referred them to others that have been happy too. read more

This company and my experience were awesome! The price was amazing! Installation was flawless! I highly recommend them!

We had K&J to our house to replace some old windows from the 1950s. The energy savings are impressive. The quality of windows and the install were both excellent. I highly recommend K&J to all of my friends and family. The installers were prompt, answered all my questions and kept the work area clean. We are very happy and have had neighbors complement us on how great the new windows look. read more

Stay clear of this company , Tony came out to give us a run down of the products and was very pleasant to work with answered questions and made suggestions , he provided us with a quote that same night and honestly worked extremely hard for us , once the windows were installed it seemed that the quality of work was not near acceptable, some windows look like they were way too small and should have never been installed ( mis-measured) they filled the gap's a half inch to three-quarter inch with caulking, one of the windows has not even been completed .I called and was polite and brought up my concerns they stated that they would get right back to me , the next day they called me and told me that they would stop by my house next time that they're in " the area "to take a look no date given . The following day they call me and ask for the remaining balance and I asked them when will somebody be coming to take a look at the work that is in question and I was told next time somebody is in "your area" they would stop by, I 100% understand that mistakes happen this was a pretty big job 14 windows , however being told "next time we are in your area we will call you " and not setting a date or have any compassion for the client that spent good money at your place of business is not acceptable. this company is quick to make an appointment when you were looking for a quote but when it comes to issues with their install you do not matter to them and they make it clear , I hate to leave a comment like this but if I could help someone that is in the market for new windows do yourself a favor and look elsewhere . Someone should call the register of contractors , reading some of these reviews right now show similar issues/stories. . read more

Thanks to the Yelp reviewers, I found K&J Windows to replace my double entry doors. Tony showed up on time with lots of information and catalogs to choose from. He had every detail covered. I had another door guy come Dov but he was unprepared and didn't even call back as promised. Back to K&J: We chose the doors, Zeb showed up and took measurements and installers Mike and Ryan did a professional job. There is always a glitch in replacing old with new and those two knew exactly how to tackle the glitch and the installation is perfect. They even added grout to an exposed area on our threshold. Definitely recommend this professional company! read more

I highly recommend this company. Had all windows in home replaced. Outstanding customer service, timely, reasonable price & great follow though. Salesman Toni was wonderful answering all questions, Jessica & other office staff very efficient & responsive. Nick, Solo & Dan the installers were on time, cleaned everything up, plus windows. Nick immediately recognized a problem with kitchen window & explained issue to us. He took pictures, called the office regarding problem & that same day Milgard called to arrange date to replace the defective window issue. The communication factor & follow though alone makes this company worth more stars than 5. Office staff also suggested I not pay in full, but remaining balance for cost of kitchen window will be completed once new one is installed. That also was impressive. read more

I recently had a sliding glass door replaced. The service from K&J was excellent from start to finish. I don't know everyone's name that I dealt with, but everyone was more than helpful. Thanks Luke, Beau, and Nick (and crew). read more

I found them through Yelp, and they performed well. I was remodeling and had to replace 17 windows with new framed out, larger sized windows, bnut we had to match our original 18 year old metal frames. I found the salesman,Tony, to be very knowledgeable about alternatives, he found a good match. We discussed the disadvantages of the old metal framed windows energy wise, again Tony was very knowledgeable and helpful. We had our own framer, but they installed and did a good job. I am very pleased with the entire transaction. read more

After 20+ years, I decided it was time to get new windows in my house. It has been a pleasure to work with this company. Professional, polite and "dog friendly". Great customer service...lots of communication and very comfortable. Highly recommended! read more

Recently had the original windows replaced in our home built in the late 1950's. K and J came highly recommended. We talked to just one other company. There was no comparison. This project was the smoothest home improvement project we've experienced. Cody and crew are confident in their products and take pride in their craftsmanship. We were told there might be some touch painting to do, there was none. We love the windows and can already tell the difference. read more

Had all the single pane Windows replaced in my house. Everything turned out great, a pleasure working with them.

Fantastic experience start to finish. I'm extremely happy with my new windows! I would recommend K&J windows to anyone thinking about replacing their windows. Do it now and use K&J! read more

From start to finish the salesman Tony was great, the estimator confirming sizes, staff in the office and to the installers Nick, Adam and Carlos were EXCELLENT. We replaced all windows and oversized sliding doors. Tony gave us a great price. The estimator to confirm sizes worked a plan for our renovation to fit perfect into the kitchen, we changed window sizes. The installers arrived early and were very professional, thoroughly cleaned all of their work debris and hauled away everything. I would recommend this company for new or replacement windows. Milgard misread one of the written measurements for a tiny window that came in too big. The installers called it in and before they were finished at our home, the office was already calling to let me know they already reordered the correct size window. Awesome company through and through. Professional read more

I just had my new entry doors installed and they look great! This company was the most competitive in pricing and provided great service. I would highly recommend to others. Thanks! read more

We used Yelp to select who would be installing our windows. K & J Windows had the most and best rated Yelp reviews for 2016 so we called them for a quote. Tony came out and provided a review of windows and installation. The frames of the old windows would be covered with new channel frames minimizing damage to the existing window openings and keeping the mess to a minimum. That sounded great and we had all windows quoted (11 total) at a cost of $11,000+. We decided to begin with the six most critical reducing the cost to $6,000+. We were advised to remove anything breakable and the crew would provide any other protection needed. A two man crew arrived late due to traffic and began to tear out a large bay window in the master bedroom. They laid down some tarps and proceeded to tear out the old window frame back to the drywall. Much more extensive demo than we were led to believe but John, the lead installer, made a comment that you never know what you are going to find until you tear into a window made sense and at this point we were committed to get the old window out and the new, Simonton, window in. Six windows took the entire day (actually four windows and two sliding doors). The window box in the kitchen was a real mess. At one point John was outside using a sawsall while his helper stood in the kitchen with a leaf blower blowing the dust and debris out the window. Man, what a mess that made. Finish work around the frames was left to last so it was very late when the finish work began. The finish work reflected a 10+ hour work day. Given the hour and the mess, we did not do a thorough inspection until the following morning. Finish work is at best a "3" and dust was in every nook and cranny throughout the house. We love the windows but the mess it left was very upsetting to my wife. She is a fastidious housekeeper and will not let anyone clean other than herself. It took her a good week to go through every dish, pot, pan, drawer, books and bookcases, picture frames and floor in every room of the house to get the mess cleaned up. When we called to authorize payment we expressed out dissatisfaction with not having been provided fair warning of the mess this undertaking would require and offer fair warning here to anyone who is considering window replacement. Simonton windows are very nice and we believe the investment was worth it but be prepared for some serious clean up once they are in. read more

I called K&J for window replacement however Cody explained what I needed was just glass replacement. Nevertheless he spent quite a bit of time educating me. He is very knowledgeable and professional. If my needs change or I can recommend this company I will. read more

When I was changing out my mom's windows I was looking for energy efficient windows. Working with K & J Windows, they helped me find vinyl replacement windows that were best suited for my mom's home. Their service was great, prices competitive, and they were very knowledgeable and friendly. They were just overall great to work with and I would highly recommend them! read more

K&J Windows supplied our office, 2 of my brothers and myself with new windows recently. Working with Beau and the team in the office is always refreshing and I will go nowhere else for my window needs. Beau went out of his way to make sure all of my questions were answered and I was getting the product that I need. Great customer service!! read more

From the minute Cody gave me the quote to Beau and Carlos installing, it was flawless. They were great also at coordinating other trades that had to happen. I am a landlord and live out of town, so facilitating everything for me an doing the job right was key. Could not have been better. Thank you K&J! read more

I have had my windows for 3 years. A year ago a few of the windows began to leak. I called KJ out to look at and was told this was normal by one of their employees to cover his hide. I was very frustrated and went to the manufacture who in turn contacted the owner. Come to find out the management of KJ never knew about the issues I was having because of a bad apple in their ranks. Once the owner Darrin and manager Cody found out they went into high gear to evaluate, understand and come up with a game plan to fix the issues. One window even had to be removed and replaced. They covered all of the paint and other items which they repaired and made sure they left the site better than how they had found it. They went the extra mile with repairing the issues and making sure I was totally satisfied and would only leave them a glowing recommendation. Three months ago this would have been an ugly review and one star because of one bad apple. Thankfully they stood behind their work which is a rare commodity these days. I highly recommend them from the original work and especially how they stepped up to fix a three year old issue. read more

Great Company and very fair pricing!! Don't go anywhere else!!

Looked at several window companies when the time came to replace all my single pane windows and the 2 doors leading to the patio. Darin came out measured, showed me some options and even made a suggestion for changing the configuration in the front bay window. It was a large slider, flanked by 2 solid panes and Darin suggested making the large a solid pane with sliders on the sides. Cost would be a little less and we'd have an unobstructed view. He also came out a second time when my SO was available, which was much appreciated. Chris came out for measuring and was the lead installer. They arrived on-time, found & replaced some damaged wood, pointed out other areas of potential water issues, and finished the job on-time. Job site was cleaned as were the new windows & doors, which came out beautiful. So glad we took Darin's suggestion on changing the bay configuration; it's really awesome! Thanks to all! read more

Every step in the window replacement process with this company was great. From the original appointment with Cody (he was on-time, organized, and provided a detailed estimate) to the follow-up with the office to confirm installation, to the actual work of installing 17 windows and a patio slider, everything went well. Nick and the installation crew were on-time, professional, organized, and very tidy, cleaning up after themselves. I'm very happy with the finished product. read more

Tomorrow will be a better day with new windows and doors from K&J Windows. I am very happy with the service I received from K&J. They were very helpful in helping me choose the right windows and doors for my home. I have three sliding doors and am thrilled that I can open the drapes for the view and not have warm windows. So nice to be able to let the light come in when it is 110 degrees outside. I couldn't be happier. I highly recommend this company for your window and door needs. read more

This company is amazing! I shopped for Windows on line and the big box stores. While the price was not the cheapest they were not the most expensive and when we compared the price and quality we were getting with K&J and the install it was comparable (only off by a few hundred dollars) The quality of install and willingness to help when there were issues with our GC was nothing short of spectacular. The Windows were inspected prior to being installed there were a few with defects and Danielle immediately let us know and ordered replacements. We never had to ask for the job to be done right it was right every step of the way! Zeb and the install team were great! You can not pay enough for the customer service the company provides- knowing what I know now and my experience with K&J I would never go with another company! read more

After trying to find a custom door for weeks, with many door and window companies in AZ I was about to give up. Nobody was interested in returning my calls. Then, luckily, I found Darin and Luke at K and J. They were accomodating and were willing to do anything to help me solve the "door problem." A few phone calls and e-mails later we had the design, a price and shortly thereafter an install date. The door was installed on 5/2/13, on time and as scheduled. Perfect! Easy to do business with people who care about their customers. I would not hesitate to recommend K and J for all your window and door needs. read more

Other estimates came up with..your doors are "custom $$$" .."we can replace but $$$".."here's our cost $$$"...yada yada...When Tony from K&J Windows came to our home..every word he said was sensible and the cost was reduced because Tony thought about our "custom sized" replacement French doors and came up with a solution. A line of windows & doors that they install (good quality Simonton) that could still be considered a STOCK size. This, fortunate for us reduced the price significantly. It was so good we almost thought it was too good to be true! Just as he said from the second we said YES to our order, to the scheduling and to the install..there was not one kink, question or problem. The installers (John & his brother) were prompt & worked extra long to do our job in one day! With their respectfulness to our home, the cleanliness and their skill ..well let me say we are so proud and happy to have our new sliding patio doors. The quality, the ease, the retrofit on the install in our old 1980's replacement worked. Even with the surprise that our old french door were built into the old frame of an old imbedded slider they did what was necessary to bring things up to par ..they went above and beyond to do our job as if it was there own home. The pleasure was all ours. Thank you read more

AWESOME EXPERIENCE! These guys are THE BEST! My husbnd and I got a few quotes and this the most reasonable. Cody took the time to explain everything, gave an accurate cost and we booked a date to get our new windows! Richard and his crew (Vern and Andrew) did an awesome job with installation. They were polite, honest, efficient and did a great job! I'm 6 months pregnant with a very active 16 month.....they moved all the furniture and did an amazing job cleaning up. They were all awesome with my little guy, saying "hi" back to him after the 1,000 times he said it to them! :) Such a great company with a great sales and installation team! I highly recommend them if you're looking for honesty, efficiency and great work! read more

We were extremely impressed with the workmanship and service K & J Windows delivered. Reasonable price, great staff and quality work. Cody from sales was always available and responsive with our needs; installation team lead by Coby did an awesome job. They were efficient and always cleaned up after themselves. Team had to cramp 3 days work into 2 days due to delay of shipment; they work long hours to meet the promised deadline. I highly recommend K&J Windows if you need window work; support our local vendors!! read more

This company was great.If your looking for a quality window supplier at a fair price and complete satisfaction, you need to check this business out. No pressure. Cody (General Manager) was very friendly and especially knowledgeable on the quality and features in their product line. Chris the lead installer did a pre measurement for four window replacements at the site. The final installed cost from Cody was very reasonable when we also considered this company had it's own installers, and we would be dealing directly with Cody on both any installation issues and any future manufacturer warranty conditions. At the time of installation, it was quite evident that Chris and Tim knew their craft, which resulted in a glitch free installation. They arrived and finished on-time, and cleaned up after themselves. We had a final walk-thru and everything was installed to our complete satisfaction. We have more windows that need future replacement, and will definitely use this company at that time. read more

We just had all of the windows in our house replaced. I am very pleased with the professional job that Nick, George and Erin did. They were extremely polite and did a wonderful job cleaning up. The salesperson, Tony, was just as professional and easy to work with. I would definitely recommend if you are looking for replacement windows that you give these guys a call. read more

Great experience from beginning to end. The K & J crew were professional and courteous. I would recommend them to anyone who needs their windows replaced. read more

After a move from New Mexico to Phoenix and the purchase of a house in need of remodeling and new windows, both my son and myself decided to hire K&J Windows for replacement Simonton windows in June. We had visited other places locally, no big box stores though as I prefer to hire local companies if I can, it was obvious that K&J Windows were pros and incredibly professional. We met Cody first in the showroom who showed us a type of windows from Simonton that could work for my son's house then sent us Tony to measure, give us his opinion and finally e-mail us an estimate. The cost was very reasonable and the Simonton replacement windows sounded perfect so we decided to order 7 of them. Tony was extremely helpful. Chris the head installer came to take the final measurements and installed in no time. I was still at the time in New Mexico but my son was quite impressed with everyone and the final product looks fantastic. In September it was my turn to move to Phoenix and after the purchase of my own house again in need of renovation and new windows, of course we immediately called Tony to come measure all the windows in the house for an estimate. He gave us a really good deal for 25 windows of the best quality by Simonton. Those are slightly different from my son's house since they are thicker yet do not cut the view of the lake the house is fronting. The result is unreal. It was amazing that the 25 windows were installed in 3 days by a wonderful crew led by Chris of course and that when they left the house looked like it always had those fabulous windows without any disruption to the outside paint or stucco! The service and attention to detail we have had from everyone at K&J Windows is exceptional. Jessica is always so cheerful and helpful on the phone, Tony is a gem, he gave me excellent advice even if his own interest and that of the company would have been to sell me something bigger like a large sliding door window, he suggested to keep the same window opening as before to obtain the best unobstructed lake view. Tony really takes the customer's interest at heart and I am so glad I took his advice and ordered the suggested windows. Chris as the lead installer is also very personable and explains the entire process going the extra mile to please the customer and makes sure there is no stress involved. His crew is top notch with always a smile and an unequaled work ethic. I don't seem to find enough superlatives to describe the level of professionalism, cleanliness and readiness to make the entire process easy for a picky client like myself that those guys have demonstrated during our 2 houses installs. My neighbors keep admiring the beautiful windows when they pass our house, the house has truly been transformed by the Simonton windows from K&J Windows. I am still awaiting with excited anticipation the installation of a new entrance door and 3 other secondary doors. All the costs are so reasonable, the entire experience so painless and I am such a very HAPPY, ecstatic customer! I wouldn't even loose my time inquiring anywhere else, this company is the best I have had to deal with and I recommend them with all my heart because I am thoroughly impressed by their employees, products and services. They can't be beat! Hurry and call them when you are ready for a big house transformation. To Cody, Tony, Chris and Jessica, a huge thank you for your help to make our move such an easy transition with a painless window replacement process on 2 houses. To anyone who is considering replacing windows I encourage you to start the process and assure you of a wonderful outcome, you'll be so happy when your house looks like brand new and you save on energy costs! read more

Everything from start to finish was a breeze. Each employee we came in contact with was of the utmost professionalism, and we never felt like we were getting the run around as we did with other window companies we quoted out. Installation was quick & easy, and the installer cleaned up everything perfectly. The windows themselves all look great, and our new sliding door is a dream! Would absolutely recommend this group to anyone else looking to replace some windows or doors. read more

Doing a super remodel in North Scottsdale in a million plus home. Most windows needed to be replaced as well as sliders, two doors, and we created new large custom four panel slider for the great room. Our contractor suggested K&J Windows as they were a company he had worked with on numerous jobs. The Sales Rep, Joe Golden came out on two or more occasions,(I was still living in Denver at the time, I know of two occasions). We were quoted May 9, 2017 for Milgard Essence, (top of the line), with a stainable interior so to match the other finishes being used in the home. Time line was described to me personally as 4-6 weeks, and if lucky, maybe three. This was appealing because with all new interior features, we could not proceed until the windows were in. Mid August the windows came in part. We were told some came in wrong, some came in damaged. The problems were described to us as problems with the manufacturer. Once the windows were installed, they left them incomplete, with damage to stucco and interior walls, as well as white screens for our dark stained windows, and wrong size screens. We had to pay extra for the finishing as K&J said that was not something they were responsible for, due in part to the preparation of our contractors, huh? Hello, open walls, make it work. Since speaking with people in the area, their windows were a complete package, installation, finishing, and any stucco/dry wall issues were included in their price. The windows were in horrible shape when I saw them, filthy, no screens, silicone from the install all over the tracks, which when we sanded our new patio, the sand stuck horribly. It is now The end of November. We finally got someone to come out, I was not told they would be there until at my door when I was not home. (No pre call from K&J, my contractor told me they would be out that day, but finally after 4:00, and no call, I gave up and left the house). I did give them permission to go through the back to look at the windows and was told they can not be fixed as they don't have any of the parts and will be back early next week to fix them. Of course they haven't showed. We had a house full for Thanksgiving, no functioning screens, ( still completely missing 4 or 5), flies all over the house and our food, screens literally falling on the ground when guests unknowingly tried to open and close. This has been a nightmare, so bad in fact, that they took some money off the 30k + price tag for not being complete after 6 months, trust me not nearly enough, I would have gladly paid the entire bill to get new, beautiful, and functioning "completed" windows. I have never personally received a call from the owner, or any management at K&J. My contractor keeps telling me they are promising to fix this window fiasco, but, again we are now going on 7 months with no finished product. I do not usually leave reviews, but, am hoping my terrible experience will not be repeated on unknowing consumers. Maybe there is more to the story that I have not been told, again, where is my phone call from the owner? I continue to wait, and wait, and wait...... if I could give zero stars I would. read more

These guys are awesome. Very knowledgeable and professional. They do great work for a fair price. Highly recommend!
