Spray Foam Insulation in Lombard, IL

Owner John came out to provide us with a quote for a smaller job in the crawl space beneath our kitchen. He was very friendly, gave us a reasonable offer, and informed us about energy rebates that would expire at the end of the year. We booked the job. The crew arrived promptly and got to work immediately. Our crawl space is not easily accessible (through an old hopper window located over the utility sink in our laundry room). They cleared out the old insulation and cleaned up years' worth of detritus. They were finished in under two hours and left everything tidy. Clear before-and-after photos were shared with us. Great work! We can't wait to reap the benefits of a well-insulated space.

I had Koala spay foam my cathedral ceiling that lacked any insulation. Guys came on time and performed the work within guidelines. Area was prepped and sprayed well. No funny residue and was able to return home the next day. I was very pleased with the workmanship, quality and attention to detail. My AC unit no longer runs as often as it did. Now I can’t wait how this will perform in the winter, but I can already tell a drastic difference in temperature. I would highly recommend.

Koala insulation came through for us. We wanted to have or attic insulated with blow in material John Anthony came and gave a quick quote. He showed us what they were going to do and gave us a fair price. The job was scheduled right away. The team came on time and left the house as clean as it was when they got there. It has not been too cold yet this year, but we can notice a positive improvement. No drafts or cold ceiling now. 18” deep throughout the entire attic. They gave us very good complete pictures of the before and after of their work. Very satisfied and will recommend them to others.

We’re so happy we hired Brian. He finished early, under budget, and his team was very clean and careful in our house. He also recommended a contractor to help with a different project we needed and that company is great also. Would definitely use again.

Wanted to give ten stars but only allowed five. Had two frozen pipes in the crawlspace when the weather dipped well below zero. I contacted a number of insulation companies until I met Bryan, owner of Dupage Insulators. What a great guy! Never met him before but upon first meeting he gave me an hour of his time educating me concerning my problem. He gave me a fair price for the work which turned out to be lower than the other companies and work was started within the week. His installer Jay was very respectable and very polite and did an excellent job in a swift, timely manner. Bryan further spent quality time with me explaining the job and what occurred that will prevent future problems. Overall, Bryan and Dupage Insulators is the company you want regarding any insulation needs...you won't be disappointed. Thanks Bryan!

I can't say enough about this company! They were top notch on the project that I had and it was not an easy one. They were very professional and great to work with. The price was right and they were clean and went above and beyond to help me out with insulating the upstairs of my old home. Will be recommending them to anyone I know that needs work done.
