Ofer and his team are the best in the business! They were timely, professional, reasonably priced, and did an excellent job. Highly recommend!
I had a really great experience with Clean Air Doctors. It was easy to set up an appointment, and they made themselves available on short notice. They were prompt, and very understanding when I was the one a couple minutes late for our appointment. Our dryer is in a tough/tight spot, and they really went above and beyond to access the vent to clean it, and then they taped it to alleviate the lint build up issues we were having (the vent had been installed without any tape to seal the seams, which was part of our problem). I would highly recommend Clean Air Doctors... they were kind, quick, and did a good job.
Was strangling finding good service in this field as it is so hard due to so many companies that are unfortunately just tried to rip us off and we even had to pay a lot of money for simple estimates, But Clean Air Doctors turned out to be first the most professional and secondly honest with a free estimate so we decided to hire them for spray foam insulation for our walls and let me tell ya I honestly don't think any other company in the Chicagoland could have done a better job for such reasonable price! I definitely strongly recommend

Absolutely outstanding work from beginning to end! The project manager, Javier, did a fantastic job. The project involved the removal of old insulation from the attic and walls of one room. From the initial planning, execution of the project, to the final cleanup, everything was handled professionally. I highly recommend this company for their excellent service.
Echo Tec is responsive, professional and efficient. They did a wonderful job with my home insulation.
It was a pleasure to work with Brian, Andrew, and their family business. I recently had Eco Tec at my home doing wall cavity insulation. My house is over 100 years old and largely stucco exterior, both of which present more challenges, but they were able to do get the job done mostly from the outside. I only had a short turn around time for completion of the work, repair, and clean up. Brian went above and beyond to get my final clean up done by my required deadline - thank you Andrew and Ryan. I want to acknowledge Ruben for his efforts and thorough work getting my drywall repaired, painted and back to normal. Brian is very responsive and has such a friendly, calm and competent attitude. I thought my initial quote was very reasonable considering the scope of the work. My final invoice and payment due amount was really good value. I would definitely recommend Eco Tec Insulation.

I've used Reynoso Insulation for several insulation projects, and they’ve consistently delivered excellent results. Their team is reliable, always on time, and easy to work with. One of the things I really appreciate is their attention to detail. Any time I asked them to adjust or level out insulation, they handled it without hesitation. Their work made drywall installation smooth, with everything fitting perfectly on the studs. I highly recommend them for anyone looking for quality insulation work done right the first time.
Jose and his wife and very customer friendly. Jose is knowledgeable about building construction and climate control. Insulation workers and professional, kind and clean up after themselves. Highly recommend Reynoso . Thanks again! Guillermo P
Reynoso Insulation did a great job with our second floor. For years, extreme temperatures outside, could be felt inside. This prevented us from even going upstairs in the middle of the Summer because our AC just couldn’t keep up due to the heat. And in the Winters, the heater would work overtime. We finally had enough and searched around for someone to insulate the whole upstairs. Reynoso insulation suggested a contractor to us to cut the drywall. We ended up hiring him. He was confused with the start of the project and showed up a bit late. And to finish the project, wouldn’t show up til 10 some days. But he ended up doing good work in the end. When it comes to the actual company, Reynoso Insulation came on time (8 am) for the days they worked. They worked quickly and efficiently as well as cleaned up nicely. Now, with this Summer’s heatwave, our AC is finally working like it should upstairs. Letting us know that the insulation was a job well done.

I am extremely happy about the whole process from start to finish with Daniel, and Smart Insulation. Daniel was very thorough on his inspection and offered a few different strategies for insulation in my attic. Gave me a fast estimate and was even willing to do the job on a Saturday! With these below zero temps this week, I already notice the difference. I definitely recommend this company. Thank you! -Lauren
Excellent professional workmanship. They went beyond what was quoted and did some additional repair work that was needed to ensure that the crawl space would be sealed perfectly for the next winter. The team worked hard and diligently getting the work done efficiently. They cleaned up when finished. Five stars.
This company is AMAZING. They came out and sprayed foam insulation in my attic, and they did it quickly and efficiently. The crew was very friendly, and they didn’t leave a mess when they were done!

Have used Chicagoland Sprayfoam multiple times for various projects. They’re honest, respectful of clients needs and thorough with their work. Would definitely use again. They’re extremely busy but worth the wait IMO.
Called a few times and left a message but no answer. Drove to the address from Northbrook because it says they close at 6pm and I arrive to a residence. No business advertisement and no answer at the door.
Contacted them and they never responded.
