"The previous owner I bought the house from concealed the rotten windows and the home inspector my realtor recommended did not mention that the windows need to be replaced. 5 years later, water started to come into the house and I learned that not only I need windows, but my house susteined significant damage. I looked for a local company willing not only to replace the windows, but to fix the potential damage as much as possible. Not a same day or 2 days replacement company that will slap the new window in the rotten frame but someone willing to replace a rotten stud or seal. And I found Travis that made me an excellent impresaion- honest, knowledgeable and surprisingly, not pushy. After an initial quote I let it sit for about 2 weeks until I decided and except an email asking me if I have more questions...which I had -about 10 of them lol, he let me decide. In 4 weeks his team was already on site. Now his guys are the best. I had Adam and Rafal installing my windows and oh, my , when they opened the walls I was looking in disbelief at the rotten wood. They were able to replace all that rotten wood including wood studs, top and bottom seal, joists, etc and make the window casing look like new. Most companies either walk away or cover the rot but these guys were absolutely amazing. Every detail was adressed and every concern was answered. And I was not an easy customer because I was over concerned and watched everything they did, asking a bunch of questions. Yeah, that kind of a customer. What can I say. There are a lot of windows companies but these guys standed apart being able to handle this complex and challenging project. Highly recommended, a company that stands apart through the quality of work and professionalism."

"Gus and his team at EcoChamp Windows & Siding are amazing! They were very professional, responsive, and installed high quality windows in our home at competitive pricing. I love my new windows and Gus’ suggestions really made a difference. My husband and I highly recommend this company!!!"

"Tomek did excellent job installing vinyl siding on entire house. He also did all suffits and windows installation, the work passed the city inspection. No violations or mistakes. He went extra mile to make sure the job was completed correctly with great attention to detail."

"We had to replace 3 windows and a huge patio door. The replacements were smooth and we love how easy they are to open/close. We can already feel the difference with our new patio door, and have a nice cozy family room now! Russ was incredibly helpful and accommodating with our timelines. The staff has always been friendly and quick to respond to us. We definitely recommend Chicago Window Guys!"

"This pair of true craftsmen worked magic on my old but serviceable 28-year-old wood windows. Two casement & two large fixed windows suffered substantial cosmetic rot in sash, sill &/or brick-mold. Windows were removed & completely rebuilt. The skill displayed in fashioning the intricate re-framing of the windows from 4â x4â stock using a table saw amazed me. They did additional exterior work, replacing rotted wood trim around the garage & chimney areas. All work was caulked, & repainted. Half dozen other contractors shied away from any cosmetic repair, each suggesting full window replacement. Work was done very reasonably compared to replacement cost, they look brand new. I thank God they came to DeKalb for us & saved our beautiful windows. Prayers answered, they have our highest recommendation."

"11/04/18 I am changing this review. One of the things they did was cut off the bottom of the sliding door so it would slide easier. The work was done in August. I didn't notice until fall / winter, there was no weather striping and the wind was blowing in, actually snow was blowing in. I had to have a new sliding door installed which I did 2/22/18. I never did hear back from them about the balances for the double-hung windows. Very prompt service. I contacted them Tuesday, August 22, 2017, the sliding door was repaired the following Monday. Alex explained the repair (it needed a new track) and why it was needed. The double hung window needs new balances, Alex is checking into the part. I was very happy with their work and will recommend them to anyone who needs a sliding door repaired. I had contacted 3 other companies. One said it couldn't be fixed, buy a new door; one didn't respond; and one was to busy to handle the repair now. I am thankful Sliding Door Repair Service was able to help me. They did such an excellent job!"

"Jeff was on time, work done right and pleasant to deal with. He put in a dog door on our back door. Very nicely done."

"Mike was a pleasure to deal with. He is very down to earth. We had him install 18 interior doors and 6 bi-fold doors. He keeps you in the loop on where the project stands and did the job for a fair price. I would hire him again for another project."

"It was wonderful, he knew just what to do and fixed the door. Everyone else didn’t have clue."

"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."
