I live in Buffalo Grove, IL, and recently hired OTS Chicago Insulation to insulate my crawl space and I’m extremely happy with the results! After doing some research and calling a few companies, I chose OTS because of their professional approach and detailed consultation.

The floors on the first level are no longer cold, the air quality has improved, and our heating system isn’t working as hard this means real energy savings!If you're looking for a reliable insulation company in Buffalo Grove to handle your crawl space insulation project, I highly recommend OTS Chicago Insulation.

I live in a single two-story home in Schaumburg, IL, and was dealing with a significant temperature difference between the first and second floors. After calling around to a few insulation companies, I came across OTS Chicago Insulation. From the start, I was impressed with the salesperson, Ofer, who performed the initial inspection. He took the time to clearly explain the pros and cons of different insulation options and provided a very thorough and professional presentation.I decided to hire OTS Chicago Insulation for the project, and I couldn’t be happier with my decision. It’s been a few months since the insulation work was completed, and the results are outstanding. We’ve seen about a 10° improvement upstairs, making the second floor much more comfortable to live in. I highly recommend OTS Chicago Insulation for anyone looking to improve the comfort and energy efficiency of their home!

I had an issue with my second-floor rooms being too cold, so I reached out to OTS Chicago Insulation for a consultation. They offered a free consultation, which was a great start, and Ofer—the technician who came out—was very knowledgeable and professional.One of the biggest advantages of choosing OTS was their financing options. Unlike the other two companies I contacted, OTS offered 0% down financing, which made the decision much easier for me.On the day of installation, the team arrived on time, completed the job as promised, and left my home clean when they finished. I really appreciate their efficiency and attention to detail.Overall, I’m very happy with the service and professionalism of OTS Chicago Insulation. I hope this insulation solves my second-floor temperature issue, but based on my experience so far, I highly recommend them. Thank you so much for your excellent service!
