"Ricardo was not the cheapest but knew what I needed in a room ruined by freeze/thaw action last winter. He went the extra step and installed ceiling insulation as well."

"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."

"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!"

"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."

"George came out promptly and did a thorough inspection of the crawlspace and provided options on what can be done. The insulation work was performed by Jesus who also found and fixed two foundation cracks. Encapsulation was done by Juan's team and they all did a great job. They were able to perform all the work with a very narrow opening into the crawlspace and were also able to fit in the dehumidifier. After installation there was a minor issue with the dehumidifier and Craig came right away to fix it. Great experience and I'd definitely use their services in the future if need be."

"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"

"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."

Insulation questions, answered by experts

Completing insulation service projects in Chicago delivers immediate comfort by reducing drafts and stabilizing indoor temperatures during harsh winters and humid summers. Over time, you’ll benefit from consistent energy efficiency, quieter living spaces, and fewer allergens entering your home. Proper insulation also helps prevent ice dams and moisture issues, supports HVAC longevity, and can increase your property’s resale appeal—especially important in Chicago’s competitive housing market.

Helpful?

In Chicago, attic insulation service projects usually take two to four days, while whole-home insulation may require two to four weeks due to planning, inspections, and permit processing. Basement or crawl space insulation often finishes in three to five days. Project timelines can be affected by weather, contractor scheduling, and the age or complexity of your home, so plan ahead—especially during Chicago’s busy spring and fall seasons.

Helpful?

Insulation service projects in Chicago require periodic maintenance to stay effective. Inspect attics, basements, and crawl spaces annually for signs of moisture, settling, or pest activity, especially after heavy storms or extreme cold. Address air leaks and condensation promptly to prevent mold and energy loss. For older Chicago homes, consider professional evaluations every few years to ensure insulation continues to meet energy efficiency and home comfort needs.

Helpful?

Chicago homeowners should consider the city’s temperature extremes, high humidity, and older housing stock when planning insulation service projects. Many homes have unique framing or masonry that requires tailored insulation solutions. Be aware of permit requirements, especially in historic neighborhoods, and check for available energy efficiency rebates. Scheduling projects in spring or fall can help avoid weather delays and ensure optimal installation conditions for Chicago’s climate.

Helpful?

In Chicago, insulation service contractors include full-service providers who handle everything from energy assessments to installation, as well as specialists focusing on spray foam, cellulose, or fiberglass insulation. Some contractors concentrate on attic, basement, or crawl space projects, while weatherization experts address whole-home energy efficiency. Always choose professionals familiar with Chicago’s building codes, local rebate programs, and the unique needs of older city homes.
