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.

From the first time I reached out requesting an estimate all Russ could talk about was his reviews…read more He seemed to care more about the reviews on his company than actually providing good customer service. He came to my townhouse to give me an estimate to replace five windows. He was in my house 20 minutes threw out a number to me and wasn't even going to write it down in a proper estimate. When I asked him if he would put it in writing, he scribbled it on his brochure. I went to his website to find out what I would actually be getting because his brochure didn't say it and there was no information that I could find that would tell me what I would be getting for the dollar amount he scribbled on his brochure. I later followed up with an email with additional questions and he did not respond. I honestly didn't expect him to but I wanted to see if he would. Way too concerned about reviews and not actually providing customer service. Very happy I did not hire him!!

After researching several window companies, I ultimately chose Window Door Pro for my project,…read morewhich included replacing my original 1976 white casement windows with ProVia Aspect windows and installing a new ProVia sliding glass door (replacing a patio door that had been installed by a previous owner in 2011). From the beginning, Robert stood out because of his extensive knowledge of ProVia products, window installation, and the industry as a whole. He took the time to answer my questions and explain my options, which gave me confidence that I was making the right decision. The installation itself presented an unexpected challenge when the crew discovered that my original windows had virtually no existing frame. They had to build new framing, which required additional lumber, but it was the right solution and not entirely unexpected given the age of my home. I was also impressed that the team completed the installation of my second-floor condo in under five hours without using scaffolding. They also went above and beyond by concealing some unattractive roof flashing that had always bothered me, which made a noticeable difference in the finished appearance. The final result looks fantastic. I've received numerous compliments from neighbors and even other contractors on both the style of the new windows and the quality of the installation. No project is without a few hiccups, and I did have a handful of post-installation issues. Shortly after installation, the secondary bottom lock on the sliding door would not engage, the screen needed adjustment, and the door required more effort than expected to close and lock. Robert personally came out, adjusted the sash and locking mechanism, and the door now glides effortlessly and locks exactly as it should. On another visit, Robert replaced a weatherstripping bulb seal on one of the casement windows that had been manufactured too long and wasn't sealing properly. He also cleaned adhesive residue that had been left on the exterior glass after installation. While the cleanup inside and around the work area was very good, the adhesive marks on the outside of a second-floor window were difficult for me to access, so I appreciated that he came out promptly to take care of them. Overall, my only suggestion would be a more thorough quality-control inspection immediately following installation. While I understand that new windows and doors may need minor adjustments after settling into the home, catching a few of these items before the project was considered complete could have eliminated a couple of return trips. What truly sets Window Door Pro apart is Robert's commitment to customer service. He stood behind his work, responded quickly to every concern, and made sure everything was corrected to my satisfaction. It's refreshing to work with a company that doesn't disappear after the installation. I would confidently recommend Window Door Pro to anyone looking for quality products backed by exceptional service. The only reason I did not give a five-star rating is because I believe a more thorough quality-control inspection immediately after installation could have identified and corrected these minor issues before they became service calls. That said, Robert's responsiveness and dedication to making everything right were exceptional, and I would not hesitate to recommend Window Door Pro to others.

He came out, was well versed on window styles in the neighborhood and our home and matched it accordingly without being asked. He was very communicative, understood the quick turnaround needed, expedited the custom order with low expedited fees, and he installed them the day after they arrived. Best of all, he went above and beyond in coming out a separate time to look and quote one of the other windows in the house that would fall spontaneously. It ended up being a fix that could be taken care of immediately, and he did it at no charge. I really appreciated that beautiful, quality work that he did. He has a great company and stellar customer service with quality work.

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.)

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.
