Get matched with top spray foam insulation pros in Chicago, IL

"I hired Corona Insulation to remove old insulation and straw from underneath a crawlspace of an addition to our home. We bought our home 3 years ago, and one of the prior owners apparently thought it was a good idea to have layers of straw (think "bales of hay", as there was a crazy amount of it) on the floor of this crawlspace area. All it did was invite mice and probably other rodents to live there, and eventually find their way into our house (which mice have). So, as you can see, we needed this cleaned out and redone properly. Ricardo from Corona Insulation was my main contact from the beginning after going through HomeAdvisor - he then came out to do give a free estimate, and then once hired, he was also the person who handled the job on his own. Not an easy task! There was a super large amount of straw that he removed along with the old insulation - as well as some not-used/not-connected electrical outlets, a couple poles, broken pieces of wood, etc...in short, he cleaned everything out of the crawlspace that the prior owners had left there. There were 2 vents that prior owners had set up to carry heat/central air to the addition above. I say "set up", but one of the vents wasn't even connected, and the other was half-way laying on the ground, covered with the straw. Ricardo informed me that they were both filled with all sorts of debris - the straw, dirt, etc. - and, they were also cut up (probably chewed by mice, I'm guessing). So, he also offered to replace the vents and hook them up properly, which I agreed to. Along with replacing the insulation above (under the floor of the addition) with good thick layer of spray insulation, there were also 2 problem areas on the old "wall" of the house (where it used to end before prior owners put up this addition). One was a window that was since broken and not sealed - making it easy for the above-mentioned rodents to find a way into the walls of our home. And then there was another spot/opening along that wall that also wasn't covered. Ricardo suggested putting up some 1/4 inch mesh, and said he could install it for us. My wife was running errands at the time, so she picked some up for him to install for us at no additional cost, to seal up the 2 problem areas. He then used the spray insulation to seal things up further. Ricardo explained everything he was doing along the way, and did everything I wanted him to do. When he hauled the "bales of hay" away and all of the other debris, there was still a lot of clean-up to do on our driveway adjacent to the crawlspace opening...but, Ricardo also swept up everything in sight. Honestly, it doesn't even look like he was there, everything was so clean on our driveway. Corona Insulation did an awesome job, and I'd highly recommend them for your insulation needs."

"They did a great job of removing old insulation and installing better insulation and areas that were not insulated before."

"It went really well. Robert Carroll really knows his stuff. Hire this guy. I say that without reservation of any kind. Don't look any further, believe me, I did. This is the smartest guy. He is honest, dependable, offers fair pricing, and his team can do all the work. I got several estimates from A+ rated insulation companies, but Robert was more knowledgeable than the other companies. He was the only one to point out that my soffits were not vented. Apparently, my house was built on the day no one was inspecting. The builder never cut open the soffits. That meant there was zero airflow going through my attic. The attic fan could run all day, but without air to move, it would not do any good. Only Robert noticed this and offered a solution to fix the problem! I asked some of the other A+ companies if they would vent the soffits and they all said they don't do that work, but they would be happy to add more insulation, which would not fix the problem if the attic was not vented."

"I am very happy with the work done by Green Attic Insulation. David and Charlie were very friendly, professional, responsive, and flexible in working with my changing needs. I originally was looking into insulation but then discovered there was mold in my attic. As the job grew, David, Charlie, and their team worked with me to address the additional parts of the job. I really appreciate their knowledge and the thorough job they did. They took many pictures of their progress and kept me informed each step of the way. Thank you very much!"

"Attic Pro Insulation did an outstanding job! They contacted me 10 minutes after I entered my search information.They were professional, on time, and explained everything clearly. Highly recommend them for anyone needing quality insulation work!"

"Very accommodating company. Responded to all my questions and concerns, treated my home with the utmost respect and left it clean. The room was a bedroom carpeted by prior owners. When I removed the carpet, it uncovered a nightmare. The room used to be part of the garage. The previous owners left the oil spills. dirt, and cracks and just covered it with carpet. Soooooo disgusting. Perma seal ground out the cracks, pumped poly foam underneath for support, sealed the cracks, ground them to level them, and it even looks like they tried to clean up the disgusting oil spills left by previous owners. (I'll be doing additional scrubbing). I will wait for spring thaw to assess its waterproofness before I order my new floor. See before and after shots."

"Wonderfully. Ryan was a very knowledgeable pro and gave me an insulation estimate on the same day. He also found an antique Dutch Oven in the attic dating from 1920, so we've gotten an heirloom in the bargain."
