The process of getting 4 new windows was so easy and efficient with K & J windows! Everyone I spoke with through the process was friendly and professional, especially our installer Joseff. read more

This company is the whole package. They offer great products, but more importantly their service is second to none. You might be able to get a decent window somewhere else, but you won't ever get the kind of friendly, professional, knowledgeable service that K&J offers. Don't waste your time anywhere else. read more

I'm blown away on how good the experience was working with K&J. My installer Joseff was so professional, efficient and knowledgeable. His work was impeccable. The quality of the work and product was outstanding. The owners even stopped by to check on the progress. I could tell that this family owned company takes pride in their work. I recommend K&J to anyone wanting to replace their windows. read more

We purchased replacement window from K & J for our entire home. Very impressed with the installers, Misa and Ivan. Polite, kind & courteous, couldnt have better folks on the job. Abel the supervior stop by to make sure installation was going well. There was one hicup and it was taken care of. I highly recommend these folks when buying windows. Good people and Good price. We are very happy. read more

A big thumbs up to K & J. They installed 25 Milgard windows at my house 2 weeks ago. This took 4 days and the install crew showed up on time and cleaned up each day and answered my question as I watched over everything. I was worried that my stucco might not come out right, but even that was on point. I also double-checked the windows at the end and the only thing I found was a casement window that was a little sticky to open and they quickly fixed it. Regarding the quote process, Tony was easy to work with, knowledgeable about their products, and revised my order several times as I worked out the final details. I had a few concerns, like making sure that when I replaced a narrow window at my front door that the frame would not be too thick, but it looks great. Also thanks to Debbie for checking after the job (and after I paid) to make sure I was still happy. Based on the job they did at my house, my neighbor is going to update their windows too. read more

Sliding glass door replacement. Good quality. Professional. Prompt. Fair price. Sales person, Cody, was a pleasure to work with.

Window still leaking after it rains with paint bubbling at the bottom corner of the window. We have a 10 year warranty on the windows and it's only been 5 years since installation. All we ask is K & J come out and take a look but they refused. I'll be filing a complaint with the manufacturer tomorrow. Update on review 02/13/2024 Received a call from the owner Darin and setup a time for him to come out to determine how the windows were leaking. After inspecting the window and roof he determined that the window was not leaking and the issue most likely was the roof. He gave us the phone number of a leak specialist to call. Thank you for following up to resolve our issue. read more

We had K & J windows install 25 brand new windows, a side door and change a French door to a sliding door. I cannot even begin to say what a wonderful experience it was. From the salesman who came to the house with no nonsense pricing gimmicks, to scheduling and the installation crew everyone was nice, respectful and professional, on time. Even when our dog escaped!! The best part is how they handled adversity. Any company can do a great job when things go well, a truly good company handles adversity with prompt responses and resolution. Our first snag was when replacing the side door we found the previous homeowners had the door installed on top of electrical wiring. They sealed the opening and had to wait for us to get an electrician to move the wires. Then the manufacturer cut one window 4 inches to short, they were on the phone immediately with the company to have a new window ordered and installed in less than 3 weeks, amazing. I never had to call to follow up, they always called me and kept their promises. read more

K & J Windows - Huge picture window they installed! - Windows Installation Near Me - Phoenix, Arizona

I had windows and doors installed in July, 2022. 4 months later, I finally have the warranty issues resolved and ready to do one of several reviews. To begin, a good and trusted friend referred this company to me. A person I've known for over 7 yrs. who has actually built homes. She is someone I trust. She only installed windows. So I didn't shop them, huge mistake! Unfortunately, I experienced the inconsistencies of this outfit. I made my initial complaint to the GM and she stated she would come on site (my home) and review the issues along with the installer. Upon arrival, I learned the owner Darin Garcia was in place of the GM and Zeb, who I believe owns the install group along with the door Rep. who I don't recall his name. I said, wow, the owner came out. Upon Darin's visit he stated and I quote, "if you lived in south Phoenix and talked me down on my price, I wouldn't be talking to you" (I live in Scottsdale). After that comment, I shouldn't need to write anymore and won't as I have a lot. Not enough room here. After his visit, Darin wrote me an email stating, "don't call or respond to my email as we will delete it" "if you defame me on social media you will hear from my lawyers". Also in that email, he attacked me personally saying I had issues. Almost forgot, the installers showed me how to open and close the kitchen window before they grabbed their $10k and split. Installers and sales person are 1099 workers, subcontractors. Renewal by Andersen warns you of these outfits in their commercials. I have pictures to support my experience. I've heard great things about Affordable Windows in Gilbert, AZ. They're dealers of the Simonton windows. Cornerstone is the parent company of Simonton who have been around since 1941. Stay clear of this outfit and especially their doors!!!!!! Darin will most likely provide a rebuttal. The more defensive, the more it will solidify my experience which was poor. Tell ALL your friends to avoid this outfit and especially the ones in south Phoenix. read more

We bought replacement windows from K&J for our entire home. There was some issues along the way but K&J and the owner Darin went out of their way to make things right. This company has a lot of integrity and have good people at the top. I would do business again and highly recommend. read more

We had 19 windows replaced and they gave us the best price for high quality windows. Every person we dealt with at this company was very nice and professional. They answered every question we had. Our installers were Jose and Jacob. They did a great job. Very professional and very nice. They installed 19 windows in 4 days and cleaned everything up. Jose and Jacob are a huge asset to this company. Would highly recommend this company and the installers read more

We were extremely happy with K & J windows when they installed our windows and doors in 2014. Update: I called with a warranty issue 10 years later!!! Debbie was extremely friendly and helpful. New parts being ordered for repair. I have recommended them in the past and will continue to recommend K & J. read more

Reached out to them online for a window repair on Sunday afternoon. Got a call back Monday morning. After discussing the problem, they let me know it wasn't something they worked on. Really appreciated the quick call-back and them letting me know how to proceed. read more

Another fantastic job by K & J Windows. In 2018 we had K & J Windows completely replace all of the windows in our home on Love Court in Fountain Hills. They did an outstanding job we gave them five stars and it was well earned on their part. You may be able to find my previous review here on Yelp. Knowing what kind of work they did for us back then we didn't even hesitate to call them to come and give us an estimate for patio doors and man door for our new house. Once again K&J was not only the lowest bidder but also the best quality product. We got the best quality and best price and then we got the best installers. Jose and Jacob who are a father son team worked tirelessly, flawlessly and expertly for the entire day. I was extremely impressed how independently they worked yet seamlessly the entire day. I didn't realize Jacob was Jose's son until the end of the day. It wasn't like a father teaching or instructing his son, they were truly separate and well qualified workers. You could tell they had the experience and expertise to do this entire job independently if they had to. So hats off to K & J Windows for another five star job. If you're looking to replace your windows in your residence do not hesitate for a second to contact K & J windows. You'll be impressed with their high quality of Windows, installers and customer service. They are by far the best around. read more

Had an appointment scheduled for almost a week and received an email confirming my appointment. The day/time of my appointment, no one showed up. I received a call an hour later saying there was a mix-up and they can reschedule it... I took a vacation day off of work and waited around, what a waste! The lady who called to reschedule was unfriendly and unapologetic and acted like it was no big deal. In looking at other "reviews" on here, it seems like most of the 5-star reviews all say the same thing and are all from new Yelp accounts with no other review... just saying. read more

Replaced over $22000 of windows and doors. We shopped and researched extensively We settled on Milgard then were fortunate to find KJ Windows Spearhead by Yelonda(their GM) we were rewarded with quality service,solid quote,and competitive price! They blew 2 "big box" stores out of the water! Without any reservation,we recommend Kj for any job!! read more

Update: we recently had a warranty miscommunication issue that the owner rectified and it just cemented our AAA rating of this company. He personally called me and was extremely accommodating in helping us out! Thrilled to also hear they now service Prescott! We'd recommended this company in the past and those friends are still very happy with K&J! Do yourselves a favor and call them for new windows! read more

It has been a year since the installation and my selection for K&J Windows installation. Everything is as good as day one. Nice and easy to clean, cooler in summer, and a lot more quieter. I have no regret for my selection. Thank you again. read more

Had new windows installed today. The crew was very professional and efficient. Everything look great! They cleaned up their mess and I can't even tell they were here. I had several quotes and follow ups with other companies. K and J was the only one who didn't tag on a bunch of unnecessary fees. I would definitely recommend K and J Windows read more

Nick and Solo and Cody from the K&J team took care of everything and made the new window process so much easier than I expected. Little things like putting down plastic to keep dust off items in your home and doing it all for a very reasonable cost. Some other companies basically wanted to charge the cost of a new Lexus to do my doors and windows and K&J delivered the quality at a much more reasonable price point. They also did my parents home, would highly recommend! read more

I found this company after reading multiple people were satisfied with their work on the next door app. The first person who came out to tell us all about the different types of windows, show us samples, take measurements, and give us a quote was Tony. He was incredibly knowledgable, professional, and confident. After meeting him and doing a little research we decided this was the right company for us. (As a side note we were comparing this company with another window company who was also highly rated and in business longer than K&J). Next, Zeb came out and measured. He worked with our schedule and was very flexible. He was very easy to communicate with and even answered my calls multiple times on a Saturday morning. The windows came in much faster than expected which was a great surprise and the install was setup only 2 days later. Brandon and Andrew came out for the install. They were on time, professional, and extremely careful about keeping our house clean where they worked. My husband and I watched them install and they made sure each window was perfect. They took their time, and left the house (interior and exterior) just the way it was before. The women in the office were wonderful to talk to and called the next day to make sure everything went well with the install. As for the actual windows we could not be more thrilled. They are beautiful, clean, energy efficient, and we immediately noticed a difference in the temperature in our house. Our house only has 5 windows and was so dark before. The new windows let in beautiful light without the warmth and the exterior looks so updated that our neighbor commented on it the next day. If we ever need windows again we will be calling K&J. We highly recommend them! read more

K & J Windows - Before and after - Windows Installation Near Me - Phoenix, Arizona

I wish I could give a long review about a positive experience with this company. You certainly think you will when you pick the #1 yelp rated windows vendor. Unfortunately, I never got that far. I called approximately a month ahead of my appointment time due to the fact that we are not in town frequently. We needed help with windows at a condo we just moved into. After talking with the person answering the phones we scheduled an appointment for about 4 weeks away. One business day before install, I missed a call and had a voicemail from K&J cancelling my appointment. They said "They reviewed the job and it's not something they do." They gave me a different business to call (who of course can't come out on one day's notice..and we leave town again the next day). If its not something they do, how did they figure that out when the person scheduling said that they DID do that? Why wait until the day before? Unfortunately, just led to a frustrated "potential" customer. read more

Great customer service. Bought new windows from this company. Estimate was exact on price. Great product and great price. Installation done in one day. Very easy process. read more

Cody was great. He picked the right window for the job and did not try to up sell us. They came in ahead of schedule and the installation was on time, well done, and clean. read more

I had four Millard windows installed installed in my 55+ home in Sunland Village in Mesa. After reviewing the order I found that the wrong color was ordered, tan not white. The error was corrected and did not delay installation. The windows all fit perfectly into the cinder block openings. The installer Jose did an outstanding job installing the windows and a masterful job sealing/caulking the new windows. Jose was very personable, answered all my questions, and provided me with final warranty document. Overall a professional experience for me the home owner. read more

Five stars for sure! I couldn't be more pleased with the work of K&J Windows, replacing 7 windows and 1 patio door for me. From beginning to end, it was a great experience. Everyone was super friendly. What made my experience great: - Sales consultant was very knowledgeable, asked the right questions and made me feel comfortable choosing my new windows. Not trying to sell me more than I needed or wanted.  Also giving me enough time to decide. - I received a professional quote in PDF format, detailing costs per window and labor. This should be standard but I mention it because I received pricing from competitors who had just scribbled one lump sum number on a piece of paper. - Quote was very competitive. - Expectations about delivery times and installation process were set correctly. The, by far, best part of the project was the installation by Jose and Jacob. They did an exceptional job. Old windows were out and new were in very fast, without any damage and they cleaned up everything very nicely. They even washed the new windows. They were friendly, accommodating and fun to talk to. They built me an additional exterior trim for my patio door that was NOT replaced, so that it would match the new very nice ones that they had to build. I can't praise Jose and Jacob enough - they really put the J into K&J Windows! I highly recommend that company. read more

This whole team was outstanding. From start to finish. I wish they did more than windows. This was a completed window and door replacement of our house It started with Cody. He was professional and explained all of our options in a low pressure environment. Once we decided to go with K & J, they never disappointed throughout the project. The team kept us informed during the ordering stage. Once the windows arrived, they kept their word on the installation start and completion times. The installation team of Nick, Solo, Carlos, Scott, Gary, and Pepe were unbelievable. They were on time every day. At the end of each day, we came home to clean house. They even let our dog out during the day. We kept waiting the bad news to start with a project of this size. It never did. They exceeded all of our expectations. read more

repeat customer -completing the rest of our windows. Everything about this company is 5 star. Zero pressure sales, great prices nothing hidden. Installers professional and fast. No cleanup required after they left. No damage to interior and zero stucco damage - If your looking for quality AZ windows without any hidden fees or charges K&J is who you want replacing your windows. Don't hesitate to at least get a quote it will be worth it. read more

I bought a new (to me) home in June. It was an older home (1982) with original windows (aluminum single pane), no screens, and I could feel the heat just pouring in as my ac worked overtime to cool down the house. That's when I decided I needed to get new windows. Now. I had about 4 different companies come out to give me an estimate. The first was outrageously priced and I about fainted at the price (20k! For 8-9 windows). The following 3 were about the same price give or take a few hundred. The reasons I decided to go with K&J was simple. Cody, the guy who came to give me my estimate, was knowledgeable and friendly without pressuring me to sign any contract or overcharge me for every little thing. He gave me the info I needed to make an informed decision along with his email or phone number to ask questions as they came to me later. Which I did! A lot. (Sorry cody!) Lol Second, they did everything they said they'd do and more. The install was scheduled in a timely fashion, it was easy to contact someone if I had a question or concern, and they were helpful and considerate. Next, the install crew was amazing. They showed up on time, got right to work, set my mind at east about any concerns (I'm a worrier), made sure my dogs were safe as they moved through the house, were considerate of the heat, completed their work in a timely manner, cleaned up after they were done! I mean, what else could you ask for?? The windows are beautiful! Exactly what I asked for. I can now keep out the heat when I want or open up a window for fresh air- without the bugs! I can already notice a difference in my ac and the noise reduction inside my home. From start to finish this was a outstanding process with K&J. I recommend them to everyone! Ps. If someone pressures you to sign up with them- don't! Run straight to K&J! read more

Cody was very professional and answered all our questions on the windows and the install process. The quote was reasonable to replace 9 windows in our 70's block home so we hired them. It did take a few months for the windows to come in, but they did come in a month ahead of schedule. K&J was able to get us scheduled for the install right away. The installers arrived on time and were very courteous and clean. They did a great job on the install and we are very happy. read more

Updating to 5 stars. Why? Because K&J earns it! I received a call from Darren (the owner) who reviewed the debris situation with me and immediately sent a team over to remedy the issue. Darren went above and beyond to make everything right and the follow up actions were taken care of so well, that I even decided to go with K&J to replace my doors and sidelights after all. K&J really is a family-oriented business and when you become a customer, it feels like you also become family. I fully trust these guys, for all of my current as well as upcoming needs. Choose K&J, and you'll see why. Thank you Darren, Cody, Zeb and the rest of the Family! read more

Where to begin! K & J was a breeze to work with from start to finish. We had several quotes from various companies and they were all high pressure and over priced. Tony was laid back, very thorough and explained everything and had great suggestions on what windows to use. Once we received our quote and accepted it, they immediately scheduled our windows for measurement. I don't recall who measured them, but he also had great suggestions regarding the sliding doors and the type of finish. (We thought we wanted French doors). We opted not to go with a French slider. Once the doors were ordered they immediately scheduled installation. They called a couple days in advance of installation and went over what to expect and when they installers were going to arrive (7:30 a.m.). Promptly at 7:30 a.m. Dennis and Carlos were at our house Monday and started immediately with installation. They were very professional and super easy to work with. The installation was impeccable and they took great pride in the quality of their work. They were thorough in finishing details with the sealing (inside and out), stucco around the sliding doors, colored screws to match the frames, window cleaning and were extremely spotless throughout the entire construction process. The entire process was a breeze from start to finish and I highly recommend K & J Windows for your window project!!!!! read more

We are glad we took our neighbors advice and used K&J to replace all of our windows. From start to finish 5* service all around included the great install team of Denis, Carlos, and son. Stucco repairs guys also top notch. It was long job and watching them you could tell everyone was exceptional at what they did. And as a bonus we dug the music they had on while working - ha! read more

I actually feel sort of bad for giving this place a 3 star since they've pretty much aced yelp so far. I will say this about buying windows for your house... it's a pain in the ass, and it can be stressful. If you're like me, you'll do some research online, talk to a place like Home Depot, call around and get a few quotes, and feel lied to a lot... Ultimately, you'll settle on someone who earns your trust the best who also comes in the cheapest. K & J, aside from a few hiccups during the courting phase of our relationship, was great over the phone. They were willing to bend over backwards to earn my business. They weren't able to beat the lowest price I found, but they were willing to come close, and I ended up choosing them because they earned my business. The installer came out and was really nice... good with small talk as well. He did a pretty good job too overall. I mean, all of my crappy old 70s single pane windows were replaced with efficient dual pane windows. Toward the end of the job, he made an error with the trim, and after some hemming and hawing, we settled on a resolution. He had to rip it out and re-install it. It isn't perfect, but it'll look fine after paint. Yeah, I haven't painted it yet. I'll get to it. The mistake put him off schedule, so I think he sort of had to rush toward the end. He missed some spots with caulk, and I suppose I could be happier. I wouldn't ever ask them to come out again to change it though, and I wouldn't ask for a refund either. They did a fine job. Not necessarily exceptional, but good enough. I mean, he cut and nailed in some trim for me, and it's not really what they do. So why the 3 stars? I feel like I was a little misled and oversold on the benefits of new windows. My electric bill has actually gone up since last year. I haven't changed the thermostat. It hasn't really been hotter. I'm not doing anything different, but my bill went up 3 out of 4 months this Summer. I replaced the back door since last year too (which used to have a giant dog door and got direct sunlight half the day), so I don't have any exterior doors or windows that aren't rated for high efficiency or whatever. It's possible I've got a spot in my house somewhere I'm not aware of where I'm losing cool air or where heat is getting in... same could be said for your house - so don't just assume that your bill will drop by 1/3 and your new windows will pay for themselves. It's also possible something is wrong. I don't know. I do know that a cricket got in behind the trim where there was no caulk and he harassed me with cricket sounds for 3 weeks. One thing I do like is that it's quieter in my house (aside from the crickets). New windows certainly do help with noise. Wish it kept my house cooler. If my bill didn't go up, I would have given them a 4 - possibly a 5 if things had gone a little smoother (and also just to be nice and support local business). 3 means A-OK, and I don't think it'll bring the average down, but I must be honest here. I know they are good people, and they're great with the customer service and such. I'm posting a picture of my SRP bill so you can see what I'm talking about... read more

Just had 4 windows replaced and very satisfied. Nick ,Larry and Solo did a very professional job in a timely manner. Highly recommend. The three windows upstairs done in one half day. read more

After extensive quotes and research of various companies to have all of our windows and front door replaced we chose K&J Windows. We are extremely glad we did!! Darin's professionalism from the first day provided us confidence in his work. He went through every detail, provided good suggestions on selecting windows, followed up on all questions and was very patient with us. Office staff was very helpful in competing the quote and returned calls promptly. Nick and his crew were very thorough in removing the old windows, installing the new Milgard Ultra Series windows and cleaning up the site. Everything was top notch. The stucco job after the window installation was great and matched the existing texture. We highly recommend K&J if you are in the need of replacement windows or doors. read more

Even though I chose to go another direction, it was not due to the sales person, David was pleasant and was available for my questions throughout the decision making process. I am giving them 5 stars for their customer service. I unfortunately preferred a different product. Their price was very competitive and fair. They even beat out Lowe's by 30-40%. I cannot comment on their work as I did not have it done but their sales team were exceptionally professional and responsive. Good luck to you guys read more

K & J Windows was recommended by a friend who had used them several years ago, and they did not disappoint! A great experience from start to finish. Our new windows were expertly installed and are a beautiful and functional improvement to our home. From the first appointment in our home with Cody, who was very knowledgeable and helpful, through the installation by Nick, Solo, and Larry. Installation (9 windows & a slider) was completed in less than 8 hours. Even more amazing was the clean up! The guys were meticulous. Quality company and great pricing, too. read more

These guys were really great from start to finish. Tony was very professional and helpful while I was choosing a window type, the measurer was on time and thorough, and the installers (Joe and another guy whose name I didn't get) did an amazing job and I'm super happy with the results. I would recommend K&J to anyone! read more

Thanks to Cody and the team for the professionalism and subject matter expertise. I had to replace a wall of full of windows in my condo that were improperly selected and installed by a different (now out of business) company. I spoke with multiple companies, but didn't get the confidence that their solution would solve our problems. K&J was recommended by the manufacturer as technically solid and trustworthy. Cody worked with me, the manufacturer, and the remediation company to ensure the new windows were properly sized and installed correctly. He treated me (a female customer) with respect and went the extra mile. We would have had K&J install the windows, had there been no concerns about potential mold damage. Highly recommend this company!!! read more
