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.

My experience with Chicago Window Guys is nothing short of stellar. The windows and doors are…read moresolid and operate easily and smoothly. They needed 2 days to do the install since the job was so big. When they were doing the install on the second day, they removed the porch doors and adjacent windows to find massive water damage. The wooden frames were shot, the drywall was crumbling and there was frost underneath the floor inside under our new carpet. The 1/2 day project turned into a day. They knocked out and cleaned up all the rotted debris and rebuilt everything. They put the carpet back down and as my wife said "it doesn't even look like they were here except for the new doors and windows they left behind." And they didn't charge us a penny more!! It felt really good to give the install team a big fat tip because they totally deserved it! If you need new windows or doors, look no further... you won't be disappointed! Thank you Russ, thank you Peter, and everyone else at Chicago Window Guys!!!

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.

When I called to speak to Max he was very genuine and upfront with all the information he provided and honestly he had the best prices in the North Shore. As a Realtor in Northbrook it is always great to have access to a company / CEO who cares about his clients. Max delivered exceptional service and great pricing. His installation was flawless and the people who did the job were very respectful. They wore masks and cleaned up very nicely. I highly recommend Max and all Star for your homes window and sliding glass door replacements. I even got to shoot some Billiards with Max wow. Besides being a great window businessman he is also a great pool player. A+ Thanks Sam Rosengarten Coldwell Banker Northbrook / Home owner

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.)

Worked was described, scheduled and executed as planned, with very little rescheduling (I believe we had 1 hiccup in email correspondence, but that was quickly fixed with a phone call).

Update So made it thru a winter unfinished and the some of the caulk is starting to separate going to have to be redone.

We had Siding and Windows Group come out among a batch of 4 other companies for a roof and siding…read morereplacement after last August's hail damage. Here's how they stood out: They had excellent communication. From Angelo's estimate all the way to passing inspection, they were on top of their game. The estimate had every combination of options listed with exactly what they were going to do and photos of the planned work. We were assigned a field supervisor (Justin, I believe?) who would come out on the same day to inspect any issues we brought up. Our contact with the office via Cindy and Anthony was also superb and always timely. The work was done swiftly and well. The roofers were done before I got back from work. Siding and gutters are more involved, but they did excellent there as well and Roman et al. were excellent to work with, took feedback very well (see communication above), and were very hard and efficient workers. All in all, we were done with our project long before other houses in the same subdivision who had all signed up with doorknocker companies, and they delivered a high level of quality. To be clear, their estimate was slightly higher (my gut says 10% higher, but it's been a while since I reviewed the proposals) than some other offers we received, but for the work that we were doing, level of customization, and communication, we wouldn't make a different choice. Absolutely a pleasure to work with. Thank you, Siding and Windows Group!

I can't say I was thrilled when we were in the middle of a bathroom renovation and already pouring…read moreway too much $ for our home and we discovered (thanks to a few rainy days) that we needed new french doors leading out to our backyard. I'm usually not one to spend time getting a bunch of quotes and just rely on Yelp reviews to make a purchasing decision, but this was pricey enough purchase that i figured I should do my due diligence.' Siding & Windows Group was one of the 4 companies I had come out for a quote. We ended up with them for a few reasons: - Their quote was competitive - They were able to spray paint the interior trim with our existing paint color - They were able to match the exterior trim as closely as possible to our windows outside - Anthony at Siding & Windows Group was very responsive We placed the order on August 22nd, which is my bday. I can't say new doors was what i wanted for my bday, but i guess this is being a homeowner in your 40s. The new doors weren't installed until November 6th and we just hoped for no big storms and got lucky. Anthony checked in a few times on when they'd be installed and pushed it back a few days due to other projects. The actual installation took about a day, which wasn't too bad. A week later they came to spray paint, which honestly seemed like a much bigger project than installing the doors. That took 2 days and went smoothly, although there was a little confusion about them not knowing what color to paint, etc. It turned out beautifully and while the doors look very similar to our old doors I like the look of these even better. The exterior finish isn't a perfect match, but i think a big part of that is our old paint on our windows as faded. One day we'll touch it all up, but for now we're looking forward to a break in paying for anything for the house. I learned there are a lot of companies in the area for new windows/doors, but we were satisfied with this one and would use them again.
