Keystone was easy to work with from start to finish during our window replacement process. Steve answered all of our questions thoroughly and even made a second trip to our home to bring additional sample windows. The installation was quick, professional, and smooth. The installers were careful not to damage any existing trim work while removing the old windows and cleaned up thoroughly after the new windows were installed.

Wanna thank Keystone Window for the windows installed on 3/20/2024. The 3-person team arrived on time ready to go. Quietly and efficiently, they installed 5 windows in about 4 hours, a very professional job. And then they cleaned up afterwards. I purchased top of the line windows; the purchase price and installation were a great investment. Had windows installed in another part of my home by that other company that begins with an A, you've seen the commercials. They did a good job, but I got a better value with Keystone Window, without question. High quality windows, great price, professional installation. One other thing, the time from contract inception to installation was about 6-weeks vice 3 months with the other company. So, if your considering replacement windows, don't overlook Keystone Window. You won't be disappointed.

The installation was done with precision and expertise. The windows themselves were solid and very easy to open and close. I recommend Keystone Windows to anyone looking to improve their homes.

This was my 2nd time using Keystone for my replacement windows. I had a great experience my first time so when it came time to replace more windows I only made one phone call. Everything went very smooth and they were very thorough. They are all very nice to work with. The windows actually came in quicker than they originally said and the install went very smooth, and they were in and out with leaving the area very clean. They showed up exactly when they said they would. Could not have asked for a better experience from beginning to end.
This is our second time working with Keystone Window and had yet another great experience. Steve helped us pick out exactly what we wanted and gave us a quote right away. Scheduling the install was easy. We had a team of three men here to install a sliding door and two massive windows in our two-story family room. They did such a fantastic job, they were very professional and meticulously cleaned up after the job was done. Great experience from start to finish!

Everyone at Keystone Windows from the salesman Steve, the installers crew headed by Ivan and the customer service department have been outstanding! We had a small issue during the 1st install that was corrected the next week without any difficulties or discussion. I would highly recommend Keystone for their professionalism, honesty, integrity and all around great service!

The whole process from quote to install was very professional. If I had to make one improvement, it would be with the scheduling. It was difficult to get in touch with the individual, but once we spoke the scheduling was quick and they were very accommodating.
When we moved and knew we needed new windows, Keystone was my first thought.This is the second house we owned and have used Keystone and we cannot be happier. Rob is the absolute best and a pleasure to work with!! We had 11 windows replaced and the installers were on time, fast, professional and the clean up was done with the utmost care. If your in need of windows call Keystone, the product is immeasurable and top quality. I was happy with the replacement windows they did in my old house and am now super happy with them in my new house!

Our experience with Keystone windows was wonderful! They were professional, and did a very thorough job. The workers were very conscientious and respectful of our home. They were very careful around all of the landscaping and flowers, while installing the windows. There was no damage to the interior of the home. I would highly recommend them.

Keystone Window did an amazing job replacing all 19 windows in our home. After meeting with Rob and getting all of the details with the replacement as well as an honest, fair quote we knew Keystone would be a great fit for our project. The installation team did an amazing job especially considering how difficult the removal of our old aluminum windows was. They were very professional and clean. The new windows are such an improvement and we are really looking forward to the quieter atmosphere and lower utility costs. Overall, I am very pleased with Keystone Window and will be recommending them to anyone I know that needs window work.

We had Keystone replace four windows in our house. Their prices were in line with or slightly better than what we found elsewhere, and while the windows did take a while to come in, they were up front with us about how long it would take to receive the windows. Our windows came in within the time frame they had told us, and installation went very smoothly. Overall very happy with the quality of the windows and installation.

I had keystone windows provide me a quote for window replacement. They were very responsive, straightforward and honest with their prices and process. I worked with a gentleman named Lou who I have nothing but good things to say. I would highly recommend this business to others.

I used another window company 2 years before I heard of KEYSTONE WINDOWS. They installed the windows and just caulked around the edges. I was pleasantly surprised when Keystone put flashing around all the windows. Not only were they better than the other company, they were also less expensive and did a better job. Very professional . Left the house cleaner than it was before they came. I'm saving up for more windows in the future and I am DEFINITELY going to use them again. Highly recommend them.

Rob and his team were fantastic through the entire process, from the estimate, financing, scheduling, and installation. We could not have had a better experience. The installation team was respectful, courteous, and very efficient. We look forward to having Keystone complete the remainder of our window project next year. If I had to say one thing that stood out the most to me was Rob's personal approach, as well as his office staff's. I never felt like a number, I felt like they genuinely cared about me as a customer and an individual. Highly recommended!

From top to bottom, excellent. Started with Gary and his patience. Then the owner came out to do final measurements...the owner? Find that elsewhere. Finished with Dave and his professionalism and attention to detail. Hope you have a referral system---you may be getting some calls from my neighbors! Thanks again!
Family business quality people and products!

The staff was very professional and neat, the salesman wasn't pushy but helped me pick the right choice of windows and was very helpful! The day they installed the windows was better than I expected, they were so quick - in and out before I knew it. The crew was very polite as well, they took care of my home and anything that had to be moved to get the windows was replaced exactly as is.
Amazing work, amazing price and they replaced my 12 windows in less than a day!!! I highly recommend Keystone window and believe me we got bids from 5 different window companies and none of them came close A+++++++++
