Get matched with top window pros in Grayslake, IL

"From beginning to end this was a complete good experience. John came out and showed us the window and explained the process. After doing my research I have found the windows he uses to be excellent quality. Ordered the windows, 12 weeks to the date they were installed. The install was done in half a day. They team was very clean, helpful and complete. They answered all my questions and even let me watch! We noticed a difference within hours of sealing up the windows how cool my second story remained with the Energy Efficient windows in. I cleaned all of them with an easy process of sliding the clips and opening them. What a dream window and only wished we had done this ten years earlier. The windows were 29 years old, solid wood and clad. From the outside you can hardly tell the difference. These were a great purchase, and we are looking forward to having the other 13 windows done with Best Windows."

"Chicago Window Guys provided me with 8 replacement windows in my condo unit. The windows were fitted very well, and they were able to remove my old windows and install my new windows in a very timely manner. In addition, they were able to replace windows on the fourth floor of my building, while many other companies I contacted were not willing or able to do so! The warranty they provide with their windows also provides great peace of mind."

"I love my windows and siding. My house looks like it’s brand new. The windows and siding transformed my house. I would recommend Gus at EcoChamp Windows and Siding to all my friends and family. It looks amazing!"

"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."

"Windows rescreen was a little pricey and communication to how the technician would either rescreen on the spot vs taking back to shop was somewhat miss communicated otherwise overall good contractor. Satisfied"

"Super friendly, quick and responsive. The entire process was transparent, I learnt a lot about windows and how to take better care of them just by talking to them and seeing them do the work. Also, they kept to agreed upon dates and time. I will not hesitate to give them a call next time I have similar issues."

"A very thorough job of installation of the windows. The windows look, and feel MUCH better than Our old windows."

"Team from Power completed the work on time and cleaned up well after work was completed. Windows were measured correctly so replacement windows fit perfectly and were quality Pella windows versus no-name windows offered by other vendors."

"Jon came out measured my window and was back within a week to replace the bad window. Very professional, worked around my business timeline and was proficient. I will be referring him to anyone I know with bad windows! I catch myself gazing out the window now that I can see out of it."

"Eduardo & Jose from Apex Window Werks replaced the window mechanism on my office window and now my window functions beautifully. Great job Eduardo & Jose! I recommend Apex Window Werks."
