"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."

"Arc was great from the start. We were given a complimentary consultation by Steve Garrett, who gave us a detailed explanation on the issues we may have with our attic insulation and why our energy bills may be so high. We chose to have our attic insulated and our ducts sealed. Our ducts saw a 93.5% improvement, and we immediately noticed the difference in the temperature of our second floor. Even during this prolonged heat wave, we have been able to keep our temperatures much lower than before. The attic insulation has also decreased the temperatures of the upstairs. It has been a remarkable difference. We are fully expecting our house to be more comfortable in the winter as well. Steve is honest and reliable and we would not hesitate to recommend Arc to anyone who needs insulation and duct work."

"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."

"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!"

FAQs for insulation service projects in Oswego, IL

Old insulation should be removed when it shows damage, contamination, or heavy deterioration. If you notice water stains, rodent droppings, mold, or large gaps, plan on taking it out to protect your home’s energy performance and indoor air quality. Removing compromised material eliminates health hazards, cuts energy loss, and sets the stage for a safer, more efficient attic—all while keeping utility bills in check.

R-value measures how well insulation resists heat flow—the higher the number, the better it slows heat transfer. The right R-value keeps your home warmer in winter and cooler in summer, saving energy year-round. Match the rating to your climate zone and have a pro verify performance over time, because moisture or settling can lower R-value and cut efficiency.

Attic insulation can stay in place for 80 to 100 years, but its performance often drops after the first 15. As dust, moisture, or mold build up, the material loses R-value and allows heat to escape. Schedule periodic inspections so a pro can tell you when replacement makes sense—helping you keep energy bills down and indoor comfort up.

You can over-insulate an attic. Beyond the recommended R-value, extra layers don’t add efficiency and can trap moisture, leading to mold or reduced performance. A local insulation pro can measure current levels, confirm the right target for your climate, and advise on any adjustments so you avoid future energy or maintenance headaches.

Insulation can be damaged by mold, pests, water leaks, or accidental electrical contact. When the material is compromised, it loses R-value and can introduce health hazards. Removing and replacing affected sections restores efficiency, while routine inspections from a qualified pro help you catch problems early and keep your attic safe and energy-smart.
