"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."

"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."

"We reached out to Dan with the issue of freezing pipes and cold rooms in our old house. Dan inspected the house and proposed a plan to remedy these issues. Aside from the more traditional air sealing and insulation solutions, Dan also recommended insulating the area of our house above our soffit, which was difficult to access but that appeared to be a major insulation issue. I should add the other firms we requested quotes for did not identify this area in their proposal. I firmly believe the proposals from the other firms would not have fixed our issues. Dan worked for ~2 weeks on air sealing our attic and house, adding insulation to our attic, removing our soffit and adding insulation and reinstalling soffit. Work was done well and within budget and at a fair price. Dan is very easy to work with and takes pride in his work. We are very happy to report our pipes have not frozen and the cold rooms are no longer cold - would highly recommend Dan to others - he went above and beyond."

"Home Genius Exteriors is amazing! I have been impressed throughout the whole process with their high level of professionalism and depth of expertise. Every person I have met throughout my project has been a dream! I honestly believe they care as much about my home and doing what is best for me and my family as I do. I highly recommend! Long story about my incredible experience so far below: Our roof and siding were older, losing grit and fading, and we had lost some shingles in a storm. After having another company out that was okay/average, I did some research and read a ton of reviews. Home Genius Exteriors really stood out from the rest, so we decided to setup an appointment. Our Home Remodeling Expert was named John and he was the best! He did a complete and thorough inspection of our home inside and out (including using a drone). He even went up into our attic mid-summer to see what was going on under the roof. He then took us though all of the photos and videos and explained what was happening. He also listened to what we were hoping to improve. He provided multiple options and recommendations and answered all of our questions and concerns. Next thing I knew we were creating models of our actual home and toggling between different colors, styles, materials, etc. John was extremely patient as it took a while for us to get it dialed in just right. He wrote up our project, helped to find some discounts and areas we could save money to stay within our budget without compromising the end result we were now in love with. We decided to get a roof, siding, windows, patio door, and gutter replacement to completely makeover and modernize our home. The next day we were contacted by our Home Genius project coordinators Tiffany and Beth to schedule our roof install and to have a technician out to remeasure and confirm our windows/patio door order. I figured it would be a while to get on the schedule...They blew me away. Measurement appointment tomorrow and roof install the next day! Our measurement technician was named Frank and he arrived on time, took off his shoes without being asked (love that), and his attention to detail was impeccable. He even went as far as to reconfirm our order and to walk us through what to expect with the windows and patio door install. That afternoon Brandon, our Home Genius Project Manager for the roof install, called to introduce himself and provide a detailed timeline for the day of the install and to see if we had any questions. He also informed us when the dumpster and materials would arrive that evening. The next morning Brandon and the roofing installation crew showed up at 7:00 and began prepping our home, including hanging tarps from the roof to protect our landscaping and even moving all of our deck & patio furniture out into the yard for protection. Then the work really started - the crew was incredibly fast and efficient! They had all of the old roof off in less than 3hrs. By lunch they were done laying the new underlayment and starting to put on shingles. They worked non-stop. The roof was finished by 8:00 and what I really appreciate, is they spent almost an hour cleaning up the jobsite and even using magnets to make sure no nails were left behind in the grass or landscaping. Brandon was terrific throughout the project. He provided detailed explanations of what was happening, provided updates on timing and progress, answered all of our questions, and made sure that the installation was perfect. He even came by the next day to do a second final walkthrough to make sure nothing was missed since it was getting dark the night before. Roof looks amazing and we could not be happier! Can not wait for the next stages of our home transformation!"

Insulation FAQs, answered by experts

How to dispose of insulation depends on a few factors, including the condition of the material. While you can simply bag up and throw away many kinds of insulation, some municipalities offer recycling, so it's worth checking with yours. If there are contaminants such as asbestos in your insulation, abatement and specialized disposal are often necessary.

Opting for insulated ducts can lead to significant long-term savings on your energy bills and contribute to a more efficient HVAC system. The precise amount you can save depends on various factors, including your climate, usage patterns, and the insulation's quality. However, on average, insulated ducts can result in savings of up to 20% on your annual heating and cooling costs, according to ENERGY STAR®.

Doubling the insulation in your home also doubles the R-value of said insulation. In other words, by adding more insulation, you can reduce the heat loss by half. Most homes benefit from increasing insulation. Older homes, in particular tend to have less insulation as is, so doubling your insulation could drastically reduce your energy bills, keep your home more comfortable, and take the strain off your HVAC system.

There are two reasons why cellulose insulation repels rodents (and insects). First, the insulation has been treated with boric acid, which is a natural pest-repellent. In addition, the loose-fill style of cellulose creates less-than-ideal conditions for mice and other rodents to nest and burrow, helping to keep them at bay.

Mineral wool wraps are the most affordable and effective insulation for crawl space ducts. They are easy to cut, last for a long time, and healthier for humans. Meanwhile, fiberglass wraps are cheaper but more hazardous and difficult to handle. If you do choose to use a fiberglass wrap, make sure you are wearing long sleeves and wear proper protective gear.
