Spray Foam Insulation in Mount Prospect, IL

The Koala team and Michael were all extremely polite, knowledgeable, and transparent about each step of the project. They were easy to communicate with. The invoicing and the work were completed quickly. We had a great experience with them and would happily work with them again.

We had a great experience with Koala Insulation of North Chicagoland. They were quick to schedule an estimate, and once we approved it, they were able to complete the work promptly. The team arrived on time, worked efficiently, and maintained a very clean job site throughout. They took the time to ask thoughtful questions to make sure they fully understood what we wanted to achieve with the project. We really appreciated how respectful and professional they were from start to finish. Not only did they clean up after themselves, but they also cleared out a significant amount of trash that had been left in our attic by previous owners—something we hadn’t expected but were so grateful for. We’re very happy with the results and would absolutely recommend Koala Insulation to anyone looking for a clean, efficient, and professional insulation service.

I requested a quote from Koala North Chicagoland. Tim was very helpful and explained some things I could try before jumping to installing insulation. Was a great change from being pressured by the company into buying.

Innovative Insualtion Solutions are the best. They sprayed closed cell foam in our open attic spaces. Communication prior to the project beginning from the office regarding timing and how the job would go was excellent. The crew sent over to my home were even better. They communicated well, showed up on time each day and were respectful of my home...three things that I, as a small business owner, can really appreciate. The owner, Richard Spies, also showed up onsite to make sure all was well and to answer any questions that I had. A really great experience from start to finish. I would highly recommend them for any insulation work needed in your home.

Great communication, easy scheduling, fair pricing. Richard was great to work with and his team was friendly, clean, and efficient. We got 3 quotes for insulation and thIs was by far the most reasonable. We saw the difference in our energy needs almost immediately - we would keep the thermostat at 73 and our bedroom upstairs would not get warmer than 68. After the insulation was added the room temp is exactly what we set the thermostat to. Glad we did this before winter began. Would definitely recommend this company to friends and family.

We recently worked with Innovative Insulation Solutions, Ltd., and I couldn’t be happier with the results. From start to finish, their team was professional, knowledgeable, and efficient. The crew arrived on time, worked neatly, and made sure every detail was done right. Home feels noticeably more comfortable, and the quality of their spray foam insulation is outstanding. It’s clear they truly care about their customers and take pride in their work. Highly recommend them to anyone looking for reliable insulation experts!

From the initial quote to the install, Green Attic, was accommodating and fast. Frank came out on May 20 and squeezed up into the attic space. Found black mold on the rafters from poor ventilation due to a broken fan. I appreciated his honesty and recommendations. Ten days later, Edgar and his crew (Omar and Rigoberto) arrived. They did a great job remediating the black mold in the attic, adding thick insulation, baffles and replacing the attic fan with a solar powered fan for continuous attic air exchange. When they finished, Edgar showed me the final air flow and his crew were very respectful of the property, cleaning and tidying up the work area. I would recommend Green Attic to anyone needing mold remidiation and insulation.

We had four Green Attic workers involved over our three day project. The first day Alvaro & Jeff worked diligently at completing the mold remediation and insulation installation. They were polite, hard working and respectful of our home. The second day, Mario completed the initial mudding & sanding of the installation holes. Then on the third day, Mario and Sammy completed the final sanding and the opening of the soffit vents. These two men were also hard working and respectful of our property. The entire job went smoothly and comfortably.

Our house is drastically more comfortable after an air sealing and insulation project. They were also able to accommodate our request for a positive pressure blower door test (rather than negative), though it take a bit of back and forth to get that sorted out. They did very good work and I will definitely be reaching out again if we have any future insulation projects.

I couldn’t be happier with Chicago Green Insulation. I had a unique project, and got several quotes. Tom got the job not because he was cheapest, (which he was) but because he understood my needs and came up with a unique approach that saved time and money. I didn’t get a cheap job, I got a great job, done for less money because of Tom’s expertise.

Tom, the owner, came out to visit our home on short notice because we were experiencing vastly different temperatures on the 2nd floor of our 1890s home. He took a look at the situation, gauged temperatures, structure, and gave practical, honest alternative solutions to insulation. Since adding insulation would require certain renovations that we weren’t looking to do, Tom suggested dehumidification and hvac modification, and gave the names of reliable professionals from his contacts. He did not try to make a gratuitous sale. He maintained integrity and focused on problem-solving. So if you prefer to work with smart, innovative, and honest companies that truly want to fix the problem, give Chicago Green a call.

As a home builder of many years, I can tell you that Not all contractors are alike. I have used Chicago Green Insulation several times, on different projects. And I can say, they did an excellent job every time. Their spray crews were dependable, and got in and got it done. Tom Decker is experienced and knowledgable in the field of building insulation, and most important, Reliable. Two thumbs up!

I just had to post this review now that it is -15 deg. outside. What a difference it made adding insulation. It was the best improvement to my 40year old home. Wilkins did a very professional job. The employees explained the process and made sure the attic was well vented. Thank you!

Michael Wilkin was very professional and fireproofed my my business. I own a welding company and was very nervous about my shop. He took care of my anxiety.

Very friendly office
