I reached out to Kot's after my contractor put cheap off the shelf windows in my addition, contrary to what I expressly said I wanted. My house had original 30 year-old Milgard window's and I prioritize quality over price. Oleg was able to get out to me right away, he sent me a quote and we initiated the order. When the windows arrived and weather permitted, his team came out to replace the cheap windows and slider my GC put in and they did a fantastic job. Everyone at Kot's was so great we requested a quote for replacing the rest of the windows in the original structure which were installed last week. The whole team was fantastic to work with from start to finish. I had a lot of quotes, some cheaper but none with the level of integrity and pride in their service that I found at Kot's. Thank you Oleg, Daniel, and the crew. read more

I am writing this review as a prior Comercial construction manager and a guy who needed a window replaced. They were very responsive and communicative prior to the glass replacement. They were very honest, respectful and professional throughout all of our interactions, and they were on time and had the glass replaced with in the amount of time that they said it would take. They weren't the cheapest but very competitive. I am not only paying for a price of replacement glass but service as well, they are professional, responsive, honest and knowledgeable, and that's what I'm paying for. I will be keeping there number for future service and I recommend you do the same. read more

They ghost you for days when they said they would get back to me in 1-2 hours. They tried to give me some cock and bull story and then tried to turn it around on me for being upset for being ghosted. How hard is it to give someone a call or text to let someone know that you ran into issues or needed more time to prepare a quote. I hired someone else and they did a great job. read more

We used Kots windows for window replacement a year ago. They did exceptional work so we used them again to replace the windows in our home. Once again their workmanship was outstanding. We chose Milgard windows with exceptional UV, as recommended by Oleg. We were provided options and went with the better option. The price was well below other quotes and we received an exceptional product and service. We highly recommend Kots Windows!!! read more

Oleg and his team are terrific! I highly recommend them. I'm a general contractor and I needed a quick last minute window repair job. He responded within 1 hour, was out on the jobsite that day.

I am loathe to give a 5 star review and do it very infrequently. When I find an excellent gem, I should keep it for myself in this economy, right? However, when a business does right by me at the detriment to their own bottom line, the least I can do is say so here. Kots Windows came to assess my small job when no one else would, made friends with my dogs (better than a yelp review in knowing who you can trust IMO), and gave me a solution I could do on my own. This is an honest, old school, quality organization. You will do no better. Talk with Kots today. You will not be sorry. read more

My son accidentally broke a living room window and we needed a quick replacement. Oleg was the first vendor to respond to my inquiry and was able to come to our house within 45 minutes to take measurements. Within a day the glass was ordered and when it was ready they came over immediately to install it. The new glass fits perfectly and we couldn't be happier with the prompt service. Highly recommend them. read more

I had glass replacement done for 3 of my windows that were not properly sealed and ended up having mold grow between the panes. Oleg got in touch pretty quickly after I submitted an inquiry, set up time for a consultation/ to measure, and then when I decided to move forward, he placed an order. The windows arrived very quickly and he sent someone from his team to install them the same day. The replacements look great and we are happy with the quality and price of service. Would recommend if you are looking for glass replacements. read more

My experience with Kots Window has been fantastic. I initially thought I needed to replace the entire window, but they were very honest and let me know that only the glass needed replacement. Their quote was also quite reasonable compared to others I received. Oleg came to my home for measurement, and placed the order. His brother came over on the weekend and completed the installation efficiently. Overall, I really appreciated their professionalism, honesty, and quality of work. read more

Prompt response and good quote relative to a few other companies. Had window replaced and the installation process is quick.

Excellent service. We had a broken IGU that we needed repaired quickly and Kots got it done for us. Oleg was easy to work with, very responsive, competitive pricing, too. Measurement to install timeline was faster than expected and the work was done very well. I recommend them highly and will use them again if needed. read more

Oleg is the guy! He is very knowledgeable and he gave really good advice and helped me through some significant steps in my remodel. I really appreciated his guidance; he clearly does care about getting things done the right way and is not just in it for a quick buck. He prefers to things the right way and will tell you all of what that will entail, even when it's not what will benefit him the most or what you may want to hear. I recommend talking with him about your next project! read more

Rude response to request for quote. Did not even respond in a civilized manner. Aggressive confrontational question to begin exchange.

Oleg is very diligent and quick to respond. He did a very good job replacing a broken window for us. Other suppliers had a minimum of three windows to accept a job, so I appreciate Oleg being flexible as we only needed one window repaired. read more

Someone through a rock through one of our apartment windows. Oleg was responsive and delivered quickly. He can out to view the window, provided a written quote and started the order with my initial payment. I was contacted when the window was fabricated and they installed it within a day after that. The window was double-paned with obscured glass and the new one matched perfectly. The installation went smoothly and they cleaned up afterwards. I will use them again when the need arises. read more

I highly recommend Kot's window. Our house has two big window which are both needed to be replaced because of the glass is foggy. We request the quote from Kots and others. But Kots responded very quickly and came to measure the window and helped us replaced the glass within 10 days. Our two windows are very big and are close to the vaulted ceiling, they are very professional and very careful. We are so happy to see the new shiny windows in our living room. read more

Oleg and his team replaced my windows last year. I was thoroughly pleased with the entire process - quoting through install. We had a pressing need to get ours replaced, which Oleg set clear and accurate expectations with me based on lead times from their partner vendors. The install went quick, and final product was perfect. I've needed support following which was met with immediate attention and addressed quickly. Great communication. Highly recommend!! read more

Highly recommend Kots windows. They replaced 13 windows in our 1950's mid century brick home and we couldn't be happier with the high quality work and good customer service provided by Oleg and Kots. I shopped around to multiple companies and got quotes ranging from Home Depot to Earl Johanssen. They were all significantly more expensive and I didn't understand why. They all talked about quality, warrantee, good service. But it just seemed like so much to spend for window installation. Oleg and Kots were very competitive price wise and offered a good warranty. It was clear when I met with them they were experienced and knew what they were doing. Windows were not something I wanted to accept and take a risk and accept low quality work. We decided to go with them and are very glad we did. We chose Millard windows with bronze trim and love them. Work was done on time and on budget. The craftsmanship and attention to detail really impressed my wife who has extremely high standards. We've since referred them to multiple friends in need of windows and they've done excellent work. In my experience Oleg had been trustworthy, honest, on time with very good communication. Strong recommend. read more

We had a fantastic experience working with Oleg and his team. Oleg was knowledgeable, professional, and a pleasure to communicate and work with.

Already planning my front door replacement with Oleg. read more

We had a storm door installed by Oleg. He was responsive and flexible with our schedules. He did a great job for a good price.
