"Meva glass was incredible. Damien and his crew were very efficient and customer service oriented. They have the expertise to work in an older building such as mine with no difficulty. I would highly recommend their services to anyone who need mirror repair or removal. I intend to hire them again for the remaining glass projects in my apartment. A class act and very easy to work with."

"We used Integrity Windows and Siding back in 2012 to replace our siding and half of our windows (one of the windows did break shortly after installation - it was quickly replaced at no cost, no questions asked). Fast forward to 2023, we again sought out Integrity and Howard to install some of the remaining windows. Howard is very knowledgeable, easy to work with, explains options, kept us informed during the process and sells a quality window at a fair price. Mike, who has been with Integrity for 20+ years, was very careful during the installation - clearly he knows what he is doing! The windows look great, work great and keep us warmer. We highly recommend Integrity and Howard for your next project. We couldn't be happier."

"Excellent, Could not have gone any better."

"Everything was great, from the initial consultation and quote to the installation and even the follow-up. Customer service and communication was top notch. I wouldn’t hesitate to hire this company again and I highly recommend them!"

"We had an incredible experience with Chicago Window Guys. Everything from the initial quote to the final installation was a seamless and relaxing process. I will use them again for any window work and have referred them to others looking for the same work."

"James and Charles my installers were, professional, quick they respected my property. The all around service from beginning to end was effortless."

"Process started November 3rd of 2021. The General Manager, Eli, came to the house and showed me all of the product offerings for a new entrance door with a sidelight and transom, a replacement window for the basement, and a specialty eyebrow window replacement in our master. I told Eli that I wanted one of the best doors they offer, to replace the builder grade door, and everything we are replacing needs to match the rest of the townhouses in our subdivision. Detailed quote was sent on the 17th. The quote included pictures of each item and the door showed the wrong transom window configuration. I was told that there was no picture option to show the transom configuration of 4 panes instead of 5 but he had taken pictures to insure the configuration will match with the existing door. I signed off on the paperwork and put down 30%. All three orders where custom, so the turnaround time was approximately 3 months and that also included some of there pandemic backups on supplies. In the months to follow I would receive a few automated emails a month on what to expect, manufacturing process, and what to do on the day of installation. The emails slowed down at the end of May and I finally reached out in April. The day I reached out they stated that everything was in and we set the installation date for April 26th. Opal workers arrived on time that morning and began the process. They started with removing all the old windows and door. As they unboxed the custom products I noticed that the door glass and eyebrow window glass were wrong. The basement window they were installing was considerably smaller than what they were replacing. I took pictures of everything and forwarded the information to there main office and received a fast response. I was told that the window inserts to make the configuration correct can be done after the install. The office manager looked at the picture on the quote for the door and stated that I signed off on 5 windows instead of 4 and I had to bring up the fact that there system had no pictured example of the 4 window layout but the General Manager guaranteed that all products would match the layout of the replacement. The basement window was installed and they used tons of foam and plywood to fill the gaps of where the old window was. I could hear the installers complaining after they unboxed the new window and initially put it in place because there was so much room on each side. If this was a custom measured window how come they installed a cookie cutter size that I could have bought at a big box store? The old window, without the frame, measured approximately 60 x 54 and the new window, without the frame, measured 48.5 x 48.5. This is the only window in the basement bringing in natural light. If this is a reasonable expectation then the sales team should have brought up the fact that replacement windows would be considerably smaller. If we were told this we would not have replaced the window at all. On top of the window being small you could see between the sliding glass as if there was no seals on the window at all. Air was coming in from the outside and there solution was to cut two pieces of thin molding in half, which did not close the gap. I was told that in order to fix everything it would take a couple months. I was not comfortable with paying the remainder of the $10,000. I wanted a guarantee that they would some how make this fix a priority, so we agreed to hold back $600. Two months turned into 5 months. The office manager called me once in that time frame and stated it would not be until September. It's now October and there has been no follow up. Maybe the $600 was less than what it would take to make the job right. For the first time in almost 20 years we have a gnat problem in the basement from that brand new Opal window. We would be better off just buying something to replace it. All in all there wasn't a single product that was right and the years of saving money to increase the value of our home was not what we were expecting. We will see if the pictures attached and review will get a response and then I can update it accordingly. I would be wiling to show pictures of the fixes and how there installers do there finishing work."
