Get matched with top insulation pros in Deer Park, IL

"We badly needed insulation in our attic. We got three quotes. Weather Shield was not only the most reasonable, but the only company in which the owner both gave us the quote and installed the insulation with colleague. We could not have asked for more professionalism or better service. Would highly recommend Gus."

"My attic was poorly ventilated — damp, musty, and overdue for attention. After deciding to bring in a professional, Randy came out to my home, thoroughly assessed the problem areas, and put together a detailed quote on the spot. The scope of work included removal of the existing insulation, air sealing around all attic entry points, sanitizing, air baffle installation, and installation of new Weather Blanket cellulose insulation. The new cellulose achieves an R-value that meets or exceeds Illinois code requirements. I couldn't be happier with the results. I've already noticed a meaningful improvement in temperature consistency and overall comfort throughout my home. If you're looking for a trustworthy, professional insulation contractor, I wouldn't hesitate to recommend Paragon Insulation & Services."

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

"Very professional and courteous team. Five team members where here for six hours installing, new fan roof vents, removing old duct work including a bird nest, installed new vents between the beams, discovered builder originally did not properly insulate one area above master bath and corrected that area too. Had insulation blown in very deep to R49 and once done with house attic had garage attic also fixed and insulation installed. We have seen a big improvement, bedrooms are so warm now we keep thermostat on 63 or 65 from midnight to 0800 and 65 to 67 during the day. Garage is not freezing anymore and recently with temperatures at 30 to 10 degrees outside the garage is still between 47 to 43 which keeps any garden, household or automotive products from freezing out there which helps with storage of these products. A professional team from evaluation, quotes, installation, office scheduling, payments and follow-up. Highly Recommended. Thank you, Robert USN Retired"

"Attic Air absolutely lived up to their reputation. They did a GREAT job! I did my research in creating a short list of 3 bidders for the job. I have a bi-level house (4 levels) with 2 attics. We had black mold on the underside of the roof which we had remediated a week before having Attic Air come in to fix our ventilation and insulation issues. Our upstairs floor was cold in the winter and hot in the summer. The attic ventilation and insulation needed to get fixed, and I wanted to make sure I hired a good company to do it the right way so I never had to worry about it again. I made the right choice. The temperature throughout the house is so much more even now. Before Attic Air came out, the basement and sub-basement were freezing and the first and second floors were warm and hot. My over-sized top of the line Trane a/c unit was working overdrive to try to cool the 2nd floor and never could do it. The top floor is so much cooler now than before. It's really going to save my a/c unit in the long run. Attic Air was not the lowest bid of the 3, but you get what you pay for. If you want to get the best quality this is the company you want. I would haven't have changed a thing. Worth every penny!"

"Did a blow door test before and after the insulation job to check for any unaddressed leaks. Very thorough work, highly recommended"

"Jeffrey, did a great job installing insulation and air vents. Cleaned up well after!"

"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!"
