My daughter's house needs new windows and I thought I would help her by sorting through the various window suppliers out there. What I found was that Semko was by far the best option for us. The Semko's treated us like family and worked with us to ensure all our needs and wants were satisfied. Great people, great experience. read more

Very professional all the way through. Windows look AMAZING - it makes it look like a whole new house. Clean up was so thorough it's like they were never here. Great price, very friendly - highly recommended! read more

Just had four windows replaced with Semko. I found them through Yelp and was more than pleasantly surprised; very fair pricing, short lead times, efficient, professional and left our home without a spec of debris after the installation. I would highly recommend Semko. read more

I own a multi-unit rental building in East Humboldt Park and was looking to replace some old single pane windows that were broken and rotting. Plus the windows were odd sizes due to an older building so I had to get custom windows. I've never bought windows before so I contacted 3 companies to get quotes: (1) Semko (2) Chicago Window Pros and (3) Feldco. Jason from Semko came out the next day and walked me through the options and gave me a quick quote and explained the process and the installation time. He also followed up with an email detailing the dimensions of the windows, the quote and everything that was included. I was impressed by how honest he was with everything and how quickly he responded when I had questions. I called Semko and was immediately answered by Jason every time. Semko also provided the best price and fastest installation time which was important for a rental building. Chicago Window Pros was a bit more expensive. Feldco seemed to have the fanciest windows BUT they were the most expensive. They claimed to be running a 40% off sale but then the salesman tacked on all these installation charges and other items and it seemed like I was getting nickeled and dimed for everything. The Feldco quote was $700 more than the Semko quote and the turnaround time was 3-6 weeks!! Furthermore, Semko offers a lifetime window and labor warranty on all their windows. Feldco offers a lifetime warranty on their window but their labor is only good for 5 years. So if a Window or screen breaks you'll pay a ton for labor. Plus the reviews for Semko were just awesome. So I went with my gut instinct and chose Semko. Sure enough they lived up to their word. Within a week and a half the custome double hung white vinyl windows were ready to be installed. Two guys from Semko (not outside contractors) pulled up and installed the windows within 4 hours. They also noticed that all of the inside window stops were rotted so I talked with Jason and the guys agreed to replace them all for a small fee. The windows, caulking, stops, etc were all really well done and I'm VERY happy with the job they did. I would recommend Semko to everyone for their honesty, good work, lowest prices, quality windows, lifetime warranty on everything and turnaround time. read more

I had a very old house that needed over 20 windows- Jason came out and gave me a quote to have everything done including additional trim build-outs around existing glass block windows that I wasn't replacing and the pricing/quote he gave me was very reasonable compared to other quotes I had received- Adam and his team did the install and did an excellent job on everything. I wouldn't hesitate using Semko again as it was great dealing with a company that was so responsive and even better, was great with pricing of the windows...the new windows and trim around them look great and really helped this house look incredibly nice. read more

Excellent service installation crew and prices. Very pleasant to work with. Installation crew was very through and clean. Highly recommend

My husband and I purchased an older apartment. The original windows were in bad shape and we needed to replace them. I read the positive reviews on Yelp and gave Semko a call. Jason came to our apartment. He measured our windows, explained the process, gave us a price quote, and followed up the next day. The cost quote was all inclusive - no hidden/add-on costs for anything. We made the decision to replace our windows and, after my custom windows came in, we arranged a date for installation. The work crew was professional, polite, efficient, and respectful. There were no surprises anywhere along the way and we love our new windows! I wholeheartedly recommend Semko for Window replacement! read more

When I first decided to replace the 11 windows of my rental apartment I called the big name popular company I saw on TV since they were offering the penny installation. One of their guys came out, measured my windows, and then it was as if I was buying a car; he first gave me a high quote, I refused, he brought the number down, I was still unsure, he brought it even lower while telling me how great of a deal I'm getting BUT he could only offer it that day. He even called his boss in front of me having a conversation with him as if his boss thought it was crazy to offer me such a great deal. So I signed, knowing I had three days to cancel. Later on that day I went on Yelp and found Semko with 5 star reviews so i called. Jason said he could come out the next day. He showed up, did some measurements, and since I was on the 3rd floor told me he had to talk to his contractor before giving me an estimate. No negotiations, no hassles, no games. At the end of the day he sends me an estimate about $500 less than the other guy! When I canceled with the other company they said they could match or beat the estimate I was given. No thanks, I stuck with Semko. The contract was signed on July 23 and the windows were installed on Aug. 8. I asked the contractors if they could remove or cover their shoes and they did. Nice. They started the job at 8am and were done by noon. They cleaned up after themselves and left my tenants with beautiful new energy efficient windows! read more

We hired Semko this fall for a total building window replacement project, almost 300 windows. This was a major job, 100 year old building, with big windows! Over the course of 3 weeks the Semko crews organized and completed the job. I can't say enough good things about the experience. 2 months later I'm happy to say we absolutely hired the best company for the job got the best deal and 24 out of 24 owners have commented they are 100% satisfied with the finished product. Big thanks to Jason and Adam. read more

Hal and the guys at Semko were awesome. I had a great experience from the start of the process. Never felt like I was being sold to like other large window contractors, and they were always on time throughout estimates, as well as install. The workers worked quick and were very respectful of my house and made sure to clean up after the work was done. Price was very competitive and the quality of work was second to none! Thank you for my beautiful custom windows and my storm doors! read more

Semko is amazing- my husband and I had a very bad experience with another window replacement company so we were very wary. As an experiment we replaced just 3 windows and the results are FANTASTIC. We had special concerns and they were accomplished - Semko will now do the entire back porch next year. 5 stars. This company listens and is very helpful. Go local!! read more

Not only did they replace 10 windows in my house, they also created a hole in the wall to add one more. They did a terrific job! The workers are considerate and professional, and the price is very fair. Very good quality windows. No hassle, just straightforward and honest. Jason is a down-to-earth, responsive and friendly representative for this local, family-owned business. read more

Jason and his dad helped us out with a quote on windows for a property we were under contract on, but ultimately fell through. They were so helpful during that stressful process, that we knew we would definitely contact them when it came time to replace windows on the house we ended up purchasing. Jason came out the same day we contacted him and put together a very reasonable quote for replacement right away. Our windows arrived and were installed on time and within the time frame Jason had told us. We are very happy with our new windows. The installers did a great job and cleaned up afterwards. The windows are beautiful and function well. We will definitely be contacting Semko when it comes time to replace any other windows in the house. Thanks! read more

OUT-KCUFING-STANDING! If you go anywhere else for windows your a fool. From the moment I made the first call to Semko to they walked away when the job was done I've been in awe of their professionalism with a no pressure laid back attitude. The quality of the workmanship and windows is top notch and only took a month to have the windows custom made and only 6 hours to install. We had priced other companies and they were almost twice as much AND sent a pushy salesman with smarmy tactics like attempting to play off of two people and refusing one on one quotes. When I need the other half of my house windowed I know where I'm going: Semko. read more

Fast, easy and stress free. A friend of mine recommended Semko so they were one of the several estimates that I got. They were the best reviewed and price so I had to do it. They were out in a few days to measure and give estimate and then just a few weeks later they were installed. Done. read more

We had our windows installed today and I just wished my experience with everybody was as great as it has been with Semko. Absolutely professional, reliable, nice, great work, I can't say enough. We absolutely love the work that was done in our house, windows were ready exactly after the time we were told they would be. Starting with the estimate thorough taking measurements to the actual installation everybody always showed up on time (I had to leave home by 7:30 am, the carpenter was at my door before 7 am so I wasn't late). We left the installation crew home alone for the whole day I can't tell there was any work done, everything is clean and neat. Before choosing SEMKO I spoke with several other companies, there is nobody who will do it better. Will absolutely recommend them to friends and family! read more

Fabulous company... I don't think the experience could have been any better. We're moving into a new home and needed to have some windows replaced. Jason was extremely flexible with timing when he came out to give a quote (we're not living in the home yet, and I have a 1 year old daughter so he was understanding of us perhaps being a little late or early depending on her nap and lunch). He was also friendly, quick, and honest (I was on the fence about having the kitchen window replaced and instead of trying a "hard sell" he honestly told me that it probably didn't need to be replaced). The price was less than we had expected and the windows came in quickly and were installed in just a few hours. There was no mess at all (we only had the windows, not the frames, but it was still incredibly neat) and the windows look great. I highly recommend that you use this company! read more

Jason from Semko came out to give us an estimate to replace a broken window. We really appreciated that he was willing to come out to look at one window and that he recommended that we just replace the glass after inspecting it and finding no damage to the frame. That kind of honesty is hard to come by! We didn't end up having Semko replace the window (we got the glass repaired by Accurate Glass Shop), but the next time we need replacement windows for our home, we'll definitely be going with Semko! read more

I had my 11 windows installed 06-Oct-2016, and they did a great job! The sales person was technical and knowledgeable. They met my expectation on the quote and installation workmanship. I've save 43% on the budget, when did comparative cost analysis to F-co. I highly recommend Samko. read more

Family business with great service and prices. Discussed options for windows after measurement and assessment completed, and owner Hal convinced us that the casement windows were a better option than bay, saving us money. Installation was done on a rainy day without any mess, and every scrap of materials was cleaned up inside and out. They made sure they didn't hurt any of the plants I have all around my house. Nine window openings with a mixture of casement, picture, double hung that work together perfectly. read more

Fantastic to work with. Had 15 windows installed all one day. The bathroom window was measured a little off due to the outside brick. They initially said they would need to come back another day - which was ok with me. But around 2:00 Jay shows up with a new window. read more

We are very happy with our new Windows! Our new place is warmer and definitely energy efficient. Semko, too out our old aluminum frame windows and replaced them with energy efficient pvc ones. I highly recommend Semko if you are looking to get new Windows. They were helpful, friendly and efficient in every step of the way. Thanks!!!! read more

Purchased windows and patio door in 2014 and gave them a five star review for product and installation..After 4 yrs, we noticed a small crack in one of the windows, one call and we were told that the window would be replaced at no charge...one week later, they arrived and replaced the window in about 10 minutes...Great service again...it is no wonder why they have stayed un business so long...Great customer service and stand by their product.. read more

Great price on my three windows. On point bid, efficient installation with very kind folks installing. Solid product and experience overall. Patio door is next. read more

Hal was very professional and did his best to accommodate whatever needs we had. We originally wanted blinds in our patio sliding door but the product was discontinued by his supplier so after doing some research we decided to get it without. Installation was thorough and they did an amazing job. They were able to install it from the outside and none of our inside casing was damaged which saved me some money. The door looks great and the price was well worth the work. Definitely recommend read more

I needed new windows. Jason came to my house. It was immediately clear that they were window replacement professionals. He provided some advice on the right windows. We received other quotes and Semko were cheap without being too cheap. We decided to go with Jason and they started work the next week. The installation was quality and the results were great. No more drafts, easy to clean and beautiful. Jason gave the direct number of (773) 631 1060 for any questions. Love the work. read more

I can't say enough great things about this company. I purchased an old house (circa 1957) a year ago and all of the windows had been replaced except for two - a 6-pane bow window in the living room and a 3-pane casement window in the kitchen. The first estimate I got from another company was more than I could afford. Then a friend recommended Semko; they had replaced one of her windows and she was very happy. When I contacted them, their estimate was thousands less than the other guy, plus their reviews on Yelp were stellar. I figured I couldn't go wrong, and I was absolutely right. Everyone I encountered (Hal, Dave, Jay, the guy who measured, the workers who installed the windows) whether through email or in person were friendly, helpful, and knew their stuff. Communication was excellent. Unlike some other companies, Semko doesn't contract out their installation services. Four guys installed the windows and not only did they cover the furniture but they actually cleaned up behind themselves. They were clean, they were friendly, they kept me updated with what they were doing, no one left cigarette butts on my lawn, they even washed the windows after they peeled the labels off of them - it was an all around pleasurable experience. So now I have windows that I aren't outdated and that I can actually open. I highly recommend Semko. It's a nice family-run, family-owned business. You can't go wrong hiring these guys. read more

We visited the Semko showroom and met with Jason. Very nice and helpful and explained everything to us. Came to our house to take measurements and talked about how we could save money. His carpenter and crew came on the scheduled day and time to replace our bathroom window; were very courteous and respectful of our home. Could not believe my eyes when they were done. Replaced old glass block with a beautiful window that made our bathroom brighter and complete. They cleaned up the work area and were done in a timely manner. We highly recommend Semko and will definitely have them replace other windows in our house at a later time. read more

I called Feldco for replacement windows. The salesman was very nice, but he was in my house for almost two hours, and his initial estimate was a bit high. I called Semko. The son of the owner was the salesman (Sorry, can't remember the name). He spent all of fifteen minutes at my house measuring each window, and then he gave me a price. About twenty percent under Feldco. The windows were installed two weeks later by a very efficient crew, and the windows themselves are almost exactly the same as the windows Feldco showed me. Excellent company. read more

Wow! FANTASTIC company to work with!! Our 8-unit condo building has been owner-purchasing replacement windows over the last 2 years. We got bids from Semko and three other companies. Semko's prices were by far the best but we were most impressed with their customer service and short timeline. Our neighbors are still not happy with their big-name-brand windows and the terrible experience they are still having with that company. From the initial visit (definitely NOT a pushy sales pitch like the three other companies!) to the visit to the store (our choice - we wanted to double check and see the window in person one more time) to the visit to do final measurements to the day of install (and ok, the follow up visit that we thought was a scratch on the window but turns out was just dried glue...), every team member was wonderful to work with! Extremely polite, helpful, a true joy to work with. Day of install was absolutely perfect (and it was 30 degrees but that hardly mattered to anyone) - done in one day, cleaned up everything. That night we realized wow it was now quiet and warm in here. Did I mention the price was exactly right! I hardly ever write reviews but I was so impressed with this family/team that I had to write this! read more

Semko replaced the windows in my house. They did everything right. Professional service, fair price, excellent installers. If you like working with family businesses, give these guys a shot. You won't be sorry. read more

I know I give a lot of 5 stars, but this Semko deserves five stars. Jason is honest and trustworthy, work was competed ahead of schedule. Thanks for getting the windows in time for Thanksgiving. read more

Quality at competitive cost, thoughtful customer service, really fast installation. These guys are great, and I will recommend to family and friends. read more

Well, apparently they don't serve the south side of Chicago. Emailed them for a quote and the rep Jason called me back and told may that they were really a "North side company" whatever that means, and they have a 5 window minimum. Hmmmm., I scanned their website and saw nothing about a minimum but fine. I'll be sure to let everyone I know not the bother Semko. read more

I BOUGHT NEW REPLACEMENT WINDOWS FROM SEMKO windows 6259 w. touhy. So glad I only gave them the job for only 5 small windows and a slidding door.The windows were advance.The screens that came with the windows have gaps in most of the corners.I have never seen screens so poorly made. The have been over 7 times.The other 20 windows in need replaced will not be with Semko.What a joke all the windows needed to be painted. Because the weilds in the corners were showing.I paid an extra $1000.00 for wood grain.not wanting to see white weilds. The owner Al said he would come over and bring a gift card.Because his serviceman came over asking me for a screwdriver and a drill.I never got my gift card.I did not ask for a gift card. Just wanted my screens fixed.Al told me the frames of the screens holes are only the size 1/16. What a joke who wants to have the frames of there screens with1/16 gaps in the corners.My old screens are 23 yrs. old and no gaps.Owners be ware. Never Again. Jerry read more

The contractors that Semko uses are very bad. They don't speak english and do some of the worst work I ever seen. The materal used is bottom of the line and god forbid you have a problem. They come out and look at you like you are crazy. They left a mess and broke a outside light without even saying a word. The job was so bad I had neighbors tell me that it look like crap. Take my word use someone else. These guys outsource to a crew that doesn't even work for them directly. All they care about is flipping jobs as quick as possible. read more

I called and spoke with Jason regarding my window needs and Hal came out to our house to measure and provide the quote. We were only going to have broken windows replaced, but after our conversation with Hal and working out our budget, we decided to have all 10 windows done. I am so please with the work from start to finish and I love the custom window color as well. The installation crew was absolutely awsome. They had old windows out within minutes and were completely careful working around our furniture. They had no problem removing a large window in our dining room and the replacement is spectacular. We can't be happier with the decision to go with Semko and will definatly recommend to family and friends. read more
