"Real Seal did a great job. The estimator visited and walked me through everything, took his time to look for potential causes of a our problem, questioned up extensively about when we had problems and ended up suggesting that we start small (and inexpensive) to see if fixing a crack would solve problems. Other estimators with other companies went straight to really expensive drain tile systems without looking for other possible solutions. The work was scheduled promptly and they did a great job. They called back and checked on how everything was working 24 hours after the install, and scheduled a second visit to make sure everything was working well and that I was happy with the result. I would hire Real Seal again and highly recommend them."

"Responsive and professional! Immediately came to repair a leaking window...the fix that afternoon needed further attention...they responded quickly with an "innovative" solution. This company is what we needed - competent, responsive, attentive and professional - true problem solvers. JD"

"Called to school appt for estimate and within 2 days had owner out for estimate. I looked at 3 other companies and was slightly concerned that Best Windows was so much less. But decided to go with them and I am quite happy I did. I was told windows would be ready in 4 to 5 weeks (I had a large customize size window that 2 companies could not meet my requirements). 4 1/2 weeks later got a call for installation and we agreed 2 install was for 3 days after the call. They replaced all 8 windows and one sliding glass door in one day. And there was a lot of dry rot and frame damage they needed to work on. They did a great job. They explained why we had so much air leakage with our old sliding glass door (no insulation a around it at all and it was just places on concrete slab with no buffer so lots of air coming in that way). They clean up inside and outside very well. You couldn't tell they were here other than the lovely new windows. Several neighbors have since asked me who I used since they like the job done on my place. I have no qualms about recommending Best Windows to them."

"Great Company. Fast Efficiant work. Shawn the Window Technician was great, and Devan who was helping him install and we learned that he was actually a Production Manager. Both were great. The completed all of our windows. 7 standard, and a picture window in less than two days. Great company. Great customer service. Shawn,Devan, and Lauren were all amazing."

"Some confusion at first on start date and some coating issues but they were resolved."

"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!"

"Just had my sliding glass door by Power Home Remolding. The process was really quick and easy. The best project I’ve done in a long time. If you are shopping for sliding glass doors or windows I recommend this company. LIFETIME no questions asked warranty."
