"They were great to explain what we needed and were prompt to get it taken care of."

"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."

"Neil and his team did a great job installing the fans, guards along the ceiling and spraying all new insulation throughout the attic. Cleaned up after as well. Couldn't have gone better."

"We hired then to replace 9 windows. It was a very pleasant and easy experience from the start. Everyone I dealt with there was kind and professional. The installers were courteous and did a great job cleaning up when they were done. Would give 6 stars if I could. Now we're saving up to have them do our roof and gutters!"

"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."

"Tom and Andrew did a great job installing my patio door today. Highly efficient and completely thorough. I would absolutely recommend them for a future home improvement project when needed."

"The work was done exactly as they said. They also pointed out a problem with my flashing which solved a host of other problems for me. I would certainly hire them agaim."

"A&D provided a detailed estimate that was comparable to other estimates received. They were very professional, arrived promptly at the scheduled time and did an excellent job of setting up, explaining the process, installing the roof and cleaning up after the job was complete. Would definitely recommend their work."

"If you're looking for superior quality installation with a high level of detail, I truly recommend Seidel Exterior Group."

"Sales person was great! He was able to squeeze me into the schedule since my job was fairly small. Installers were good but some of the patched up holes are still visible. I had to hire a drywall person to level out their work"
