Report
Green Attic installed floor covering over the gravel in our crawl space, sprayed foam insulation around the foundation perimeter to keep out rodents and sprayed a foam coating over our heat/air conditioning ductwork. All work was thoroughly performed with excellent clean up. Both administrative and installers were polite, thorough and knowledgeable. We were kept informed and it was easy to contact the company for questions or scheduling. I would use their service again.

Living in a drafty 50's split level under poorly insulated flat roof ceilings for almost 20 years, the family got used to big heating and cooling bills and having cold spots and space heaters in winter. Thanks to Patrick, Johnathan, Jaime and The Truck 3 Crew, and the amazing drywall and patch and paint skills of Hugo and Mauricio, our ceilings have been fully insulated, with minimal dust and in just a couple days time. The difference during the cold spell hitting Chicagoland as I write this is remarkable! It was easy to work with Patrick via online, cell/text, to set up the job and I felt supported

Used Green Attic to have insulation installed in our attic. Patrick was very helpful and responsive. Green Attic was able to schedule for work to be done within a week of acceptance. We were expecting work to take 2 days but Henry and his team showed up at our scheduled time and were able to work the entire day to get the job done.

Green attic was a great company to work with ! Romulo and crew who came to our home to work were outstanding I highly recommend them. They were clean, made sure everything covered , attentive to us showed us pictures of everything they did up in our attic and before and after pictures . Wonderful guy and crew who worked on insulating and solar fan and a attic hatch and other work in attic . Will defiantly recommend to anyone I know needing work done . Will also be recommending to request Romulo and crew truck #7. Thanks so much looking forward to our warmer and cooler house now !

Walter, Mauricio and Jaime really helped me out as well as the whole team at green attic insulation. I had a festering issue in my attic and they were able to identify the problem, dial back the damage it had caused and provided me with a thoroughly insulated attic that was sanitized and critter free. My home is warm and that is invaluable. The three builders mentioned above were experts when prodded with questions, they arrived on time and worked hard throughout the day and they maintained an orderly job site, it was a pleasure having them in our home. When I am ready I will ask green attic insulation

And just like that Green Attic saves the day again! My upstairs neighbors refrigerator line broke, causing water to leak into my ceiling and causing significant damage to my living room wall. Per usual Green Attic really came through for me. After scheduling with the extremely professional gem, Genevieve; James (my favorite) stopped by and looked at the damage, he immediately arranged for it to be repaired by the wonderful Mike, who had it met previously before. The work was completed in one day! As usual I am extremely pleased with their work ethic and their work itself. It's kind of sad that
