We learned that the old windows were not even windows by today's standards, they were just huge panes of glass that gave no insulation. He measured the windows so quickly (like 2 minutes) that I wondered if the windows world 3 actually fit (they did!). The price was extremely reasonable; we had intended to get three estimates but my mom and I both lined Kris so much we decided to go with him right away. I chose a day for installation when Kris was going to be out of town on vacation so he let me decide if we wait to wait until he got back or if we wanted him to send his right hand man Daniel. We went with Daniel who showed up right on time on a cold morning. I thought removing the old badly cracked panes of glass would be very difficult. I was right but they got the old ones out quickly and the new ones in so fast and they finished about 30 minutes before their estimate. They only removed one window at a time and our house never got cold on a 33 degree day This was one of the best customer experiences for a project I have ever had. I chose EV Windows after asking CharGBT to find me a great window company with very good reviews and I'm so glad I did. I do not have one negative thing to say. I most strongly recommend Kris and his team.

He walked me through every step, set clear expectations, and was always quick to respond to my questions. His team replaced all 32 windows and a sliding patio door in my Arlington Heights home in early April 2026, completing the entire project in just two days. Their care and attention to detail stood out. They were incredibly respectful of the surrounding furniture, walls, and floors, and the cleanup was so thorough that the only sign they had been there were the beautiful new windows. I would strongly recommend Chris and his team to anyone looking to replace their windows at a competitive price.

A salesman came out and gave an entire spiel, we agreed to change 4 windows and waited on the rest - THANK GOODNESS for that. Because our experience was horrible! First, the salesman gave us a brochure talking about how careful they are when handling old windows, as there is a danger of lead paint. When the guy came to change our windows he didn't even put plastic down. Just charged up and hammered the window out from the outside, which left debris all over the inside of the house I called Feldco immediately complaining, and asking him to stop and send someone else. The person on the phone only cared about one thing - getting the project done right then and there so they could charge me for it. They had a great old time giving me lies over the phone and convincing me the cleaning would be taken care of - they even sent out someone for a different project to say everything will be totally fine etc. I gave the go ahead to finish the project and when I called them asking about the cleanup that was promised by the person on the telephone and the person who came to the house - they literally laughed at me and said they don't do such a thing. This was actually hilarious to them. The windows are bad quality. One window grows frost in the winter, and another is near impossible to open or close - but I will never call this atrocious lying scamming company again. Shame on me for not checking the reviews, a mistake I will never make again

Although we ended up having them install a pre-built door instead of a completely custom option, Adam came to our house to talk us through all of the options, and spent several hours going over all the details and answering all of our questions. We knew we had water damage to replace with the current door, and when it came to install, Mario and his peer did an amazing job fixing what needed to be fixed and talking though the water damage. They were also extremely respectful of our home, draping plastic over everything possible to control the construction. Although Renewal is going to be a bit pricier than other contractors around, in my mind, the peace of mind that they were going to take care of everything and leave our house in nothing short of perfect condition (significantly better than before they came, actually) was worth it. Would highly recommend Renewal by Andersen!

We had two condo units in our building update windows as well as two back hallway windows, and Jacob provided a highly competitive quote. He was kind and patient when we waited for other unit owners in the building to decide, and did not push us to move quicker or make a decision when we were not yet ready. Ordering windows took a few weeks and teams on install day moved swiftly and kept the area clean after! I also want to note that we live on the 3rd floor of a condo building and many contractors said they could not install and/or needed additional materials, external infrastructure and costs to do the project, but Jacob made it seamless with bringing windows up the stairs, and doing an internal install, which incurred no extra install costs. This was also great as it did not impact our neighbors and kept the project contained and clean. Jacob really cares about being transparent and has earned our trust, and I would 100% recommend him and his team to anyone looking to install new windows in their home. Overall, we really highly recommend Jacobs 1 Construction! I cannot say enough great things about the quality of their work, competitive pricing, and their dedication to their customers.

They came out to measure everything we needed, quoted us on what we wanted and a few other optional windows as well since we were debating on doing everything at once. After selecting the quote for the windows we wanted to get done, a down payment was made and the windows were ordered. They came in a few weeks later and two of their team members came out to install them in the morning. Everything was done quickly and professionally with care. After the install, I had a question about one of the windows since it looked like there was a small crack at the top corner and they sent someone out to look at it right away. It turned out it was just some glue residue that was attached on the inside of the window that made it look like a crack and was easly scraped off with a razor blade. I definitley recommend using Semko as they provided a very reliable service and also beat out many other window companies with their competitive pricing.

If you're considering Semko for windows, I strongly recommend looking elsewhere. My experience has…read morebeen frustrating and costly. Here's why: Warranty Issues: Semko does not handle their own warranty work. Instead, they pass you off to a third-party, which adds complexity and delays. Poor Installation Quality: When I recently had siding installed, the contractor was shocked at the poor quality of Semko's original window installation--missing foam around windows and minimal caulking. Product Problems: I've had two leaking picture windows. Defects happen, and I understand that. A reputable company would acknowledge this and honor their "lifetime" warranty. Semko did not. They denied any responsibility and insisted the problem couldn't be their product. Customer Support: Rather than standing behind their product, Semko leaves you chasing other potential issues, only to discover the real problem is their windows and installation. Yes, Semko may save you a few dollars upfront, but peace of mind matters. I wish I had spent more with a company that truly stands behind its products and reimburses for damages caused by their failures.
