"Jim Clay gave the most comprehensive quote for our insulation project. He suggested a couple of options which thought would help regulate the temperature in our home. He explained everything that ARC insulators would be doing to our home. He told us about rebates that would be credited to our bill because of a blower door pressure test and gas appliance combustion test. He presented a well-written quote. The technician for the tests and the technicians who did the insulation work showed up on time. They explained everything they were doing thoroughly. When the work was done, we did a thorough walk-thru before the techs left. We are satisfied with the work performed. We are satisfied with the money we paid. We would recommend ARC Insulation to anyone seeking recommendations."

"I met Robert for an estimate. Robert is a straight shooter, gave a competitive estimate, and no pressure at all. I decided to go with him after another estimate I got was borderline gouging. I was impressed with how efficiently and quickly his crew worked. These guys know what they are doing. Many companies can insulate an attic but Attic Air can also replace attic and bathroom fans. Make sure your soffit though has holes in it to let air into the attic. This was an optional piece for me but the crew chief explained to me the new attic fan that was being installed would burn out if there was not enough air coming in from the soffit for the fans to circulate. I also took advantage to replace two other very old bathroom fans with more powerful Panasonic 100 cfm LED fans to take advantage of the crew being in the attic. My second floor used to be 3 degrees cooler than what the thermostat showed on the first floor, but is now 1 degree or no difference. I am hoping I won't need a separate cooler fan in the summer on the second floor. Didn't need a separate heater for winter at least or shiver unless I brought up the temperature on first floor."

"Koala Team was excellent starting with John Anthony giving us a quote immediately after looking at the space. He told us about a rebate and applied it off the top. Team showed up on time, they were neat, did a beautiful job of putting the foam insulation in. We are very happy and would definitely recommend Koala to our friends and neighbors."

"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!"

Insulation questions, answered by experts

Before starting insulation service projects in Naperville, arrange a professional energy audit to identify problem areas and confirm recommended R-values for the local climate. Check if your neighborhood requires HOA approval and apply for available utility rebates early. Clear access to attics and basements, protect valuables, and compare several contractor quotes to ensure materials and methods are suited to Naperville’s weather.

Helpful?

After insulation service projects in Naperville, inspect air sealing around windows and doors, and ensure attic and crawl space ventilation is adequate. Monitor your energy usage to track improvements. Schedule an HVAC system check to confirm proper airflow. Over the first year, periodically check for settling or moisture, and plan for a professional energy audit every few years to maintain peak performance.

Helpful?

The success of insulation service projects in Naperville depends on selecting the right R-value for the local climate, thorough air sealing, and proper moisture management. Professional installation using materials designed for Naperville’s weather is crucial. Regular inspections for settling or moisture, consistent HVAC maintenance, and periodic air sealing help ensure your insulation continues to perform well year after year.

Helpful?

Completing insulation service projects in Naperville delivers immediate benefits like reduced drafts, fewer cold spots, and more consistent indoor temperatures—even during the city’s humid summers and cold winters.
