Super helpful in pointing me in the right direction. Great customer service, even if it meant losing a customer.

Great work at a fair price. Installers were very polite and efficient. Finish work was great. Would have liked more counsel on getting sound proofing since we're close to the airport. Non-soundproof windows have a noticeable ring to them. read more

Great work and very efficient. finished the work in 2 days and the pricing was reasonable. Also, the manufacturer gave the wrong screen size, but Michal followed up quickly with them and installed it in a couple of weeks. Would definitely recommend them. I was a little hesitant at first since they only work with Simonton and very few choices in that. Michal gave me the reasoning for his decision, Simonton being the most reliable, and it was fine for me, and it turned out to be a good thing for us since we liked the windows. But it might not be ok with other. read more

Michal and his team were courteous, professional and responsive. They replaced many of our windows with double paned sound blocking windows which worked well. His team did a thorough clean-up and worked according to schedule. Michal answered all questions in a timely way. They're great to work with. read more

Custom Exchange replaced my windows and sliding glass doors in one day! They are fast and efficient and extremely pleased with the work!

I messaged several businesses for my window project and Custom Exchange Windows was the only company that was communicative throughout the whole process. Scheduling was easy despite them being in-demand and my busy travel schedule. The team was punctual, professional, and also identified potential issues that I have with my window trim. I so appreciate that! I would 100% work with them again as the service was outstanding and pricing is extremely fair. read more

We own a 25 yo home and needed ~30 aluminum-framed windows, including a sliding patio door, replaced.

Our experience was fantastic from start to finish. We got a very reasonable quote for nice quality windows and decided to move forward with Custom Exchange. The actual install went quickly and efficiently - all windows fully swapped out within a day. There was no mess inside or out when it was done. The difference from the new windows is amazing - it's so much quieter inside and the house stays much more insulated now. We have already recommended Custom Exchange to other friends of ours who will be needing new windows. read more

Custom Exchange Windows - All new windows - Windows Installation Near Me

This review is long overdue! After receiving some outrageous quotes from other companies we decided to go with Custom Exchange Windows. Michal and his team are very knowledgeable and professional! He was extremely patient with my questions as i had never had windows installed before. He gave us a quick and accurate in person quote, made impactful suggestions and even brought a sample window for us to look at. The gentleman that came to install also made it a quick and seamless process. We've had our windows for a little over 6 months and we've had no issues. The sound package has been a lifesaver and we love the auto lock mechanism. Not to mention they look beautiful! Would highly recommend to anyone. Thanks Michal and Customer Exchange Windows team! read more

What can I say? Outstanding service and communication, a quality product, and a timely and highly professional installation! Michal was great to work with, straightforward and honest throughout. His price was more than fair, and we are really, really enjoying the results! It is so rare to find a contractor and business that operates like this. Yes. I would recommend Custom Exchange Windows without hesitation! read more

Michal and his team were so great to work with and their communication was clear throughout the entire process. We were referred to Michal through friends. The quality of the work and the windows is amazing. Their pricing is great too. They replaced all the windows on our house. We're so happy with their work and would recommend them to everyone. read more

Michal and his team are the best in the Tri Valley area. After thorough research online, I reached out to Michal for an estimate. He came on time and emailed me that evening to provide me with an estimate. He told me it would take about 8 weeks for the windows to arrive. I didn't bother looking at any other window companies because I liked Michal immediately after meeting him and knew he was the right guy. 8 weeks late after the Simonton windows arrived, him and his team replaced 6 windows and 1 sliding patio door. They were so meticulous, worked hard all day long, and clean. Everyone was so nice and professional. We immediately noticed the decreased level of noise. Our old windows were from the 70s and we live in a very busy area. I couldn't take the noise anymore. I am so happy that we chose Michal to do our windows. Great communication, great service, and amazing quality. read more

Nothing but positive things to say about working with Custom Exchange, they pretty much patterned an ideal experience for remodeling our house. We got several quotes for replacing the full windows and sliding door in our house, and Michal made it easy to schedule with him and gave a very quick and matter-of-fact estimate, which ended up being extremely competitive vs. other quotes we received. Scheduling was also easy, including a necessary re-schedule on our side due to covid (boo), and Custom Exchange's team arrived on time, finished ahead of schedule, and the worksmanship quality seemed high. Overall great communication, clear costs, excellent work quality, and no complaints. Would definitely recommend Michal and his team to anyone looking to replace windows in the South Bay! read more

Michal and his team did an incredible job replacing our windows and doors. Everything was done in a timeline manner, the guys were super polite and cleaned up thoroughly after finishing the job! Also, Michal made sure we applied for the ongoing promotion from the factory and sent a warranty request there. I would highly recommend Custom Exchange Windows! read more

I am more than pleased with my new windows from Michal and Custom Exchange Windows. We got quotes from five different window installers and Custom Exchange Windows not only had the lowest quote, but they also had the best ratings of any of the companies we looked at and they carried the Simonton DaylightMax windows which were a great choice for retrofit installation. Michal was great to work with and a had an extremely generous payment schedule. His two-man crew were very efficient and did a great job in the installation and cleaning everything up when they were done. If I had to go get new windows again, I wouldn't hesitate in having Michal and Custom Exchange Windows do the job. Seriously, I couldn't be happier with not only the job and our new windows, but the whole experience. Do your own due diligence, but you can rest assured that all these five star reviews are the real deal. read more

I had Michal and the Custom Exchange Windows team install new windows and a new sliding glass door in my condo. Michal is very professional and the team was wonderful. All done in one day and my house looks like a new house! I will absolutely work with Michal and Custom Exchange again when I am ready for new windows! Excellent experience. read more

Great communication, fair pricing, high quality work, delivered rapidly. 100% recommended. We had 14 windows installed in total - all excellent quality Simonton. Thanks! read more

Michal and his team replaced 7 windows and 2 patio doors in our house. I needed my patio doors replaced. Michal's prices were better than the others, so we went with replacing the windows too. They did a great job finishing the work in a day and the new doors are great for the last 5 months. A great example of Michal and his team's great work ethic is that they installed a patio door slightly incorrectly at first. Something which I would not have noticed and would have even functioned fine. But they were honest in disclosing the mistake to me. they offered to keep the incorrect door installed until they can order another door to replace it. 3 weeks later they promptly replaced the door. read more

Michal and his team installed 20+ Simonton windows for our home, including noise-reducing windows in all the bedrooms, and a sliding patio door. We've been enjoying our new windows for the past month, and we are very happy with how they turned out! We initially got a few quotes from other places, and we were feeling a bit discouraged due to the cost and turnaround time. We then contacted Michal, who came out to give us the an estimate within a few days. He was responsive and transparent, and he was kind enough to educate us on the differences between Simonton vs. other window brands. We also found his pricing to be the best. The estimated shipping time Michal gave us was accurate, and as soon as our windows arrived, Michael promptly reached out and got us scheduled for installation. Originally, the installation was quoted for 3 days, but his team worked quickly and efficiently and finished within 2 days. Workmanship was great, and we no longer feel drafts coming in through our windows. Overall, it has been a pleasure to work with Michal and his team throughout this entire process. Highly recommend to anybody looking to replace their windows! read more

Communication with Michal was clear, responsive and helpful from beginning to end. His quote for parts and labor was unmatched to any other competitors we received quotes from. After reading several reviews plus his unmatched quote, the choice was easy. My wife and I upgraded 4 ancient windows and 1 ancient sliding door to beautiful Simonton DaylightMaxs. Day of demo and install, Michal's team was very professional, polite and fast! Despite such a quick turn around (About ~4hrs), their work was completed with the upmost quality! Day following the install, all my wife could say was "why did we wait so long to upgrade our windows + sliding door?" lol. We cannot recommend them enough. Thank you so much to Michal and his amazing team. read more

Michal and his team of Custom Exchange Windows are super reliable and great to work with. Robert of CEW installed 5 windows and 1 sliding window recently and I'm quite happy with the Simonton windows. These new windows have elevated the energy efficiency of our place. The turnaround time from the initial evaluation/consultation to the installation was smooth with ease and clear communication. I'd highly recommend this company for high quality products and an excellent price point. read more

I heard positive reviews of Custom Exchange and included them in my quote process. Michal was prompt and professional when he came to do the measurements and estimate. The quote was the most reasonable and I moved forward with replacing all 13 of the windows in my home. Very communicative about the process and worked with my crazy schedule to find dates that worked for me. The installation process was so stress-free. Came on time, such a nice and professional guy! He is definitely a craftsperson at this! He cleaned up everything. The windows look so beautiful! I cannot say enough positive things about this company. Best experience I have had ever with work on my house. And the sound difference is fantastic. So glad I went with Custom Exchange! read more

Ten years later, it's still perfect! Winter: keeps the cold out. Summer: keeps the heat out. The house is no longer "drafty". ...and it also muffles any sound outside. Windows looks as fresh as the day they were installed. Thanks, Michael. I can't recommend you and your team more highly!! read more

It was an excellent experience working with these guys. They installed five new windows and a sliding door. They did an excellent job on the installation. In addition, they showed up on time for the estimate and installation. They are so pleasant to work with. I wish every contractor was like these guys. I totally appreciate them and would gladly work with them again. read more

Michal is a straight shooter who makes the process of getting new windows easy and reliable. He did not ghost me even after I took a long time to follow through, and was an immaculate professional the whole time. He gave me an estimate without any annoying upsell or pressure tactics. He then took detailed measurements so that he could perform the work to the highest standards and give me a final quote. The quote even came in a bit lower than competitors. He corresponded with me completely remotely, which was fantastic. The only slightly negative thing I can say is that the lead time was a bit more than a month, but once he received the windows, the installation of 6 windows took only a few hours. This is a minor inconvenience at worst. I would recommend him for your window needs without hesitation! read more

Michal and his team are rockstars. The whole process of getting my windows and sliding doors replaced was super smooth and seamless. Michal came over and explained to us the various options. He answered all our questions to our satisfaction. The quote was unbeatable and then the installation was quick and prompt. The crew installed everything in 2 days (20 windows and 3 patio doors) and kept the job site very clean. The workmanship is superior. I am confident that these new windows and doors will last many years. The functionality and energy efficiency is very evident now. I have turned on the air conditioning this summer perhaps only on a handful of days. These windows are great to keep the heat out in summers and in during winters. Highly recommend Custom Exchange Windows. read more

I want to leave a comment again to show my appreciation to Michal. He is very responsive to all my questions, as I have no knowledge about windows or how to maintain a house. He even came to my house to try to resolve my concerns on a rainy day. He did more than he was supposed to. I really appreciate his help and would highly recommend him. If you want a responsible guy, here he is. read more

I had a very pleasant experience with the team at Custom Exchange Windows. I appreciated that it was a small business and the owner came to do the estimate.

We are completely satisfied with their service. Michal was prompt in coming on site and giving us a quote. Michal gave us the promo from Simonton. On the installation day, his team worked efficiently and they cleaned up afterward. The look of the windows and sliding doors elevate our home. They look beautiful! We already notice the difference in noise level as well as the temperature changes. It was definitely worth the money. Will recommend them to our friends and family. read more

Michal and crew are amazing. I wish I could give them 6 stars. They're reliable, communicative, provide high quality workmanship, and offer great value. I replaced the original bedroom windows in my nearly 100-year old house. The Simonton windows are energy efficient and worth every penny! Not only do they muffle the outside noise, my room also feels noticeably cooler on hot days. Having dealt with flaky contractors...I kept thinking these guys are too good to be true. They showed up to all appointments on time as promised, Michal kept me updated on the status of the windows (there's a wait due to supply chain challenges outside of Michal's control), and they were very efficient in replacing the windows. Two guys showed up and replaced all 14 windows within a few hours. They cleaned up after themselves, took care of disposing the old windows, and the workmanship is high quality! read more

From start to finish, our experience to replace 9 windows with Custom Exchange Windows was excellent and seamless and at a very, very competitive price.

They took care to protect our floors and walls, addressed our concerns, finished quicker than expected and left behind a clean work site. I highly recommend Custom Exchange Windows! read more
