John and his team were top notch. We dealt with this in October 2018 and had our windows for about…read moresix months. Our home required about 26 windows including double hung, picture, and sliders. John met me at my home in the late evening and provided a quote. There's no sales pitch, used car salesman tactics, demonstrations that have little real-world results, etc. With other Window companies, they push their "Cadillac" windows that give a marginal performance increase for an exponential cost. Not with Best Windows. I knew beforehand they installed Kensington brand windows. They started with the manufacturer's basic line. I inquired about the mid-level line and John provided his input on why he didn't think they were really worth the additional investment. John's pricing was straightforward. There was no "oh you get a Yelp discount" or "oops I forgot to add a window to your quote, I'll throw that in for free." It was refreshing to talk to a non-pushy company for once. We went with John and his installer Chris put them in our home about six weeks later. Took about a day and a half. His crew showed up about an hour earlier and were super fast! The windows are awesome and have already saved on my heating bill this past winter.

We bought our windows from Best Windows back in 2017, and while some seals eventually failed, the…read morecompany honored their lifetime guarantee without hesitation. John, the owner, was incredibly professional and helpful--he personally replaced the windows just yesterday. It's rare to find a business that truly stands behind its product and delivers great customer service years down the line. Highly recommend Best Windows and John for anyone looking for quality products and a company that keeps its word!

The team was very responsive to both my initial quote, modifications, and inquiries. No pushy sales pitch and open for questions and suggestions. The new windows are beautiful, provide a ton of airflow in the casement design, and have received a lot of compliments. Installation was speedy and they replaced some areas of concern in rotten sills. Family run business where owners take pride in their craft.

I worked with Jay and Hal on getting 10 new windows and they were amazing throughout the whole…read moreprocess. 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.

We hired Argo to replace 9 very large, oversized windows in our family room. After getting 3…read morequotes, Argo came in with the best price and other reviews indicated they were decent. Their final price was less than half of our first quote, as they said they could just replace the glass packs instead of putting in new frames (that we didn't want anyway). They showed up on time, completed the job in 2 days (short of the estimated 3) and did an amazing job. They had a Ukrainian crew of 5 guys that worked extremely well together and were very respectful of our house. Their glass also has a very good warranty compared to some of the other quotes. Overall, extremely happy with the work they did and would use them again.

I bought my house in 2009, and from almost the day I moved in, I despised the windows. Casement…read more Ugh. Yeah, sure, they look nice, but on windy days, I had to close the windows out of fear they would turn into sails and get ripped from the frames. On rainy days, I was unable to leave a few windows slightly open in order to get some air movement (casement windows open from top to bottom, if you are unfamiliar with the term). When the windows were open, people could easily see the windows were open (hey, I live in Chicago, we worry about crime here in the big bad city). Worse, as the house settled, window after window became unusable. I finally made the decision to replace the casement windows with double hung, and after I spoke to some other firms -- including one that sent over the most "salesy," gimmick-laden salesperson I ever encountered, you've probably seen their TV ads (I had to ask him, repeatedly, to leave, and I needed an hour to get him to go, truly awful) -- I was delighted I made a call to Chicago Window Guys. The owner, Russ, was the salesperson who came to my house. Now we're talking...I like doing deals with the final decision maker. His approach was what I expected: He was on time and got straight to business. No salesy talk, no gimmicks, he simply asked a few questions, took some measurements, and made notes as I explained what I wanted and what windows were to be replaced. He explained a few options to me, answered my questions...we hammered out the price, and cut the deal right then and there. When I'm treated right, I'm a salesperson's dream. He got the deal, and I sent a check a few days later after we finalized the contract. He sent his measurement guy a few days later, he took detailed measurements, made a few more notes, and sent the order to be fulfilled. Now, this is part of the reason why CWG won the deal: they make their windows onsite, here in the Chicago area. They are not a reseller. They are not a distributor for someone else. They fabricate their own product. That cuts out the middleman, to use an overused cliche, which means they offer a superior product at less than what other resellers charge. Two months later, my windows were done, and after false start due to rain (not CWG's fault, obviously), they installed the entire order in one day. That's 7 windows upstairs, 10 windows downstairs, plus the sliding door in the master bedroom, and the sliding door and transom in the family room. One day. The crew was on time, got right to work, and did a fantastic job. They even managed to take down my blinds, then reinstalled them when the work was done. They didn't have to do that, but they did. The cleaned up their work, sealed the windows on the inside and outside...and left. Absolutely first class. I am 100% satisfied with the work and the final product. Russ's crew delivered a great product and provided great service. That salesy, gimmick-laden company, by the way, initially quoted three times what I paid CWG. If you want to be annoyed and ripped off, go with the guys on TV. If you want a quality product at a fair price, go with Chicago Window Guys.

I had Mark come by to show me some window options, and I decided to purchase a three-panel window…read more The installation was done in November 2024. Since then, I've noticed water streaks on both sides of the new window after rain -- something that never happened with my old windows. This makes me question the quality of the installation. On top of that, after the windows were replaced, I found a lot of broken glass left all over my front yard. It was clear that no tarp was used to catch the debris, and I had to clean it up myself. For a professional installation, I expected much better care and attention to detail. Only one man handled the installed the window at the end, the others came and left which may have contributed to the sloppy work. Overall, I'm disappointed with the experience and the results.

Not only do the new windows look sleek and modern, but the entire process was top-notch from start to finish. What really stood out to us was their honesty. While other companies tried to sell us on full-frame replacements, SHS actually advised us to go with insert replacements. They pointed out that our house has high-density older wood framing that was worth preserving. Following their advice preserved the character and strength of our home while saving us a significant amount of money. Their communication was excellent throughout the project, and the installation crew was fantastic: punctual, respectful, and meticulous about keeping the worksite clean. On top of that, their guarantee is rock-solid. I feel completely confident that this was a lifelong investment and that they will stand by their work if anything ever comes up down the road. If you're looking for high-quality window replacement with an honest team you can trust, highly recommend Scientific Home Services.

I am now 5 years in and the windows are in just as good of shape since when I purchased.

In fall 2024, I hired All Star to replace 6 older windows on the southwest facing side of my house,…read morewhich had been impossible to maintain at a consistent temperature. My experience working with All Star was great from start to finish and exactly what you would hope for in a contractor. Dave responded quickly to evaluate the project, he was attentive to my concerns and what I needed, and he presented me with a range of quality and price options. Based on my research and competing quotes, the cost for my chosen option was reasonable. I wanted better windows and I knew they would take a while longer to manufacture. Unfortunately, we were up against a deadline with winter coming and weren't able to sneak the job in before the weather turned consistently bad. It was definitely worth waiting for though. On the day of installation, the crew arrived on time, were very professional, and they did a fantastic job. I would definitely hire All Star again for another project based on price, quality, and service. (This next piece will not be of interest to everyone, but if you are a single female homeowner, I think you know what I'm talking about when I say that a genuinely respectful contractor who listens and doesn't just flex, lecture you, and then try to hard sell you something you don't want is a gem. Dave never asked where the man of the house was either, so thank you for that. Amazing that I have to be grateful for being respected but that's where we are. Thank you, Dave.)
