Get matched with top new windows service pros in Round Lake, IL

"I am very pleased with my window replacement through Scientific Home Services. The windows look beautiful and work wonderfully. I put off replacing windows for quite some time because I was afraid of the process. But the installers worked efficiently and had everything like new in a few hours. Both Mark and Jon are wonderful to work with. I am the third homeowner in my subdivision to hire Scientific, and with good reason."

"The replacement was done quick. Installers did a great job on installation and cleaning. Would recommend this company to anyone."

"From the initial estimate, to the scheduling, installation, and follow-up, our entire experience was top notch. Joe came out for the initial meeting and estimate for five new windows we were hoping to replace and was on time, professional, knowledgeable, and in no way pushy. And when we had follow-up questions, he kindly returned to our house the following day. Shortly after deciding to proceed with Illinois Energy and Windows, they sent a follow-up technician to double-check measurements prior to manufacturing. Our windows were manufactured and ready for installation several weeks early and Samantha made scheduling our installation super easy. Max and his crew (3 total) arrived right on time on install day and quickly got to work with laying down protective plastic and tape to keep dust to a minimum. We were told they should be able to complete the job in one day, but might need a second day depending on how the install went. Max and his crew worked efficiently, but in a very thorough manner and ended by around 3pm. The team was diligent in cleaning up all of the debris and dust and made sure we were happy with the installation and had all of our questions answered before leaving. Beyond being very happy with the final installed product, I am most impressed by the organized and professional communication we experienced from start to finish. Despite interacting with numerous points of contact, it was clear that all were on the same page and up to speed on the project history and status. I would, without hesitation, go back to Illinois Energy and Windows for additional window replacements. Great job all around!"

"McCann Windows was great! Kevin McCann came out promptly to look over the job and sent an estimate that was fairly priced (that came in the middle of the other estimates). We went with McCann because the price was fair, Kevin was very professional and informative, and took the time to answer our questions. It took a little longer than I expected for the windows to come in, but the slider turned out to be a custom order, and there was no extra charge. Once the windows were delivered, the installation team was fantastic! They worked hard all day, met the timeline to install that they promised, were personable and professional, and the cleanup afterwards was perfect. We will only go with McCann to finish our window replacements. We are very happy."

"I’m completely disappointed with the customer service I received from ThremalCraft. I called them after I purchased our new home in July 2021 and realized how many of the windows needed replacing. I wanted to work with a company that I trusted. Thermalcraft installed our windows in Elmhurst in the 1980’s and more recently put siding on that home. We were very pleased with their service in the past. Jim, the owner, came to our house in South Elgin at the end of October 2021 and we placed an order for four windows. He indicated that the windows would be ready by February 2022. While I wasn’t happy with the delay, I understood the reason and was ok with the arrangement. In late January, I identified two more windows that needed replacement and called Thermalcraft. Jim was on vacation and Pat took the call. We agreed to a time for him to come out and measure the windows. On that same call, I asked Pat when the original four windows would be installed and he said the windows were due in one week and he wasn’t going to wait for the other two. Two weeks later while at the house Pat started to change his story. Pat said that he would try to put a rush on the additional two windows and install at the same time. I said I was ok as long as it didn’t take too long. The weather (and house) were cold and we were anxious to get the work done. I called Pat a couple weeks later and asked about the timing of the new windows. Pat claimed that he wouldn’t know for another two weeks. It was clear to me that this was going to drag out, so I asked Pat to install the original four windows as you and I agreed. His response was “That’s not gonna happen.” I was a bit surprised at his response and asked why not. He said, “because I’m not going to send my team out to South Elgin twice.” Once again, I was very surprised by the lack of respect for the customer. I asked Pat to cancel the additional two window so he didn’t have to “come out twice” and he said “Well, it’s too late for that,” even though the order was only two weeks in and he couldn’t even tell me when the windows were coming. Again, no concern for the customer and a bit “heavy handed”. Pat did call at the end of March to offer one date for installation. We were going away for that weekend and Pat said his installer would call to set up another time. No phone call. My wife called 10 days later to ask about installation and at that time, Pat called her back to set up the installation in April. Again, I can’t tell you how disappointed I am at the lack of concern exhibited by ThermalCraft for the customer. It’s really left a sour taste in my mouth and of course, I’ll never use or recommend them again. Ironically, we decided to replace the remaining windows (a total of 10) in our home about a week after my conversation with Pat. Needless to say, we weren’t going to call Thermalcraft based on his poor attitude. Fortunately, I found an outstanding company who came out the second week of February and installed the windows by the end of March only 5 weeks later (18 weeks less than Thermalcraft). They are actually located further away than Thermalcraft and didn’t seem to have a problem with the distance. The windows are top quality, less expensive and have a lifetime warranty. Several of our neighbors have been asking us for recommendations. I plan to promote his company instead. The bottom line: Don’t go with ThermalCraft as they clearly are more concerned with themselves and not the customer’s needs."

"George Krinninger & Sons deserves your business. They were phenomenal and I would use them again if I ever needed to have a door installed. When we were looking to have our front and back doors replaced, we went to Menards to look at doors. While we were there, a sales associate recommended we reach out to one of their preferred contractors, George Krinninger & Sons, to assist us with replacing the doors. We did and it was the best decision. We worked with Mike and he was incredible. He was very knowledgeable, responsive, and walked us through the whole process. He even went out of his way to go with us to the store to help us pick out the right doors. When it came time for the installation, he showed up right on time, was incredibly professional, and a pleasure to chat with. When the project was done, he left the work area spotless and walked us through any features the doors/locks had. The quality of his work and the experience we had with George Krinning & Sons really speaks for itself. We highly recommend you use them."

"Exceptional product and service. Glass shower door and glass tops were all cut well. Look great! On time, great cleanup after and terrific installers. Measured several times to insure everything would have tight fit. Very happy. Highly recommend."

"Bill and Linda Berg are the ultimate professionals. They are responsive to your questions, provide excellent service, and couldn't be nicer! I heartily recommend their services."

"I learned about A & M Window Cleaning from my father-in-law, so it never occurred to me to write a review. Have been using them for both window washing and gutters since we moved into our home five years ago. Quality work, a fair price, and very nice and responsible guys to work with. So glad we found them. Highly recommend."

"It went well."
