"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."

"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!"

"Entire staff was knowledgeable, professional and courteous. The quotes we received were detailed and submitted promptly. When the day came to blow in the cellulose insulation in our garage, it coincided with one of the snowiest and slippery days of the year. The two man team arrived on time and stayed until 6:30pm to finish. End result...on budget, on time and the cellulose has made a big difference."

"I am very pleased with my new windows. I used Home Genius Exteriors to do my roof, gutter protection, and now Windows. This is an absolute amazing company, my salesman brendan was very helpful, Devan the Project Manager helped make sure everything went smoothly. Walter and Mike also from production were very friendly and professional. And Shawn, the window installer was polite,knowlagable, and efficient. And even cleaned up on his way out. Next on the agenda is to get a new door taken care of. Highly recommend HGE"

"I was hesitant at first because it felt a bit strange for a door salesman to be knocking doors during a global pandemic, but I am glad we answered! Brad was knowledgeable and gave an amazing presentation. He showed us the ins and outs of the windows, the history of the company, and provided numbers to back up his words. We live in a two story and from 1pm until sunset the front of the house faces the sun. It is very difficult to keep the upstairs cool, and the number one reason is the windows letting in so much heat. So, Brad showed us the heat lamp demonstration, and that was all it took. We bought 5 windows, and although it took 3 months before they installed, we felt the difference IMMEDIATELY. Iâ m hoping out electric bill is noticeably lower as well. Couldnâ t be happier, unless they were installed sooner but since they are custom made, I understand."

FAQs for insulation service projects in Harwood Heights, 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.
