Romuno and his team came on time and were very cordial and friendly. They discovered an issue with some electrical work while working on the insulation, which I was surprised and happy about, and were able to rectify the situation easily and at a great value, considering the timing of the project, etc. Romuno made it clear he want to ensure my satisfaction throughout the process.  When finished, the job site was cleaned very well.I highly recommend this company and all its team members and hope to do more projects in the future with them!

Highly recommend Green Attic. Scheduled to have  my attic re-insulated and Romulo and his crew did a fabulous job. The attic was in pretty bad shape prior to the work getting done and green attic made it look so good. The crew worked efficiently and got the job done in 2 days. I also asked Romulo to install a couple other things on my roof outside of the scheduled project and he very kindly and willingly did so without hesitation. Very pleased with how everything turned out. Thank you so much for a job well done! Before and after pics below.

These guys did a great job! Great price, quality service, and they offer several payment options and plans. I thought we bought a lemon of a house and the insulation and sealing job they did fixed all of our issues and were so thrilled! Highly recommend these guys. Plus they are local so it’s great supporting a chicago based company.

Great service, highly recommend! We needed our attic inspected and insulated because it was sealed off when we moved in. The team gave a pretty accurate quote though they weren’t able to get into the attic to see everything. For the work, they were on-time, efficient, communicative, and did a great job cleaning up after, can hardly tell they were here. I will definitely call them again if we decide to do more insulation work.

We have a somewhat unusual split level home that was built in 1968 that has three separate attic spaces. There was very little insulation left and many penetrations into the house. The upper level was unbearable in the summer and we imagined it would be very cold in the winter. We chose Green Attic because we felt they were more meticulous than other companies, providing the most detailed quote and explaining all aspects of air sealing and use of cellulose insulation. For anyone looking to insulate, please note that air sealing is just as important - you will not get much benefit from insulation if conditioned air from your home can be exchanged with your attic! Unfortunately, after the job started, they did find mold, but the extra cost to remediate was certainly worth it. After the job was completed, we were not surprised the temperature of the house improved, but what we were surprised at was the significant improvement in indoor air quality. Just see the attached before and after as an example of how bad our attic was vs. how good it now is.

We had Green Attic out to give us a quote for garage and attic space. Their Team 5 (Alex, Omar and Herbert) came out and worked for 2 days, non-stop. Alex discovered an area of mold in the attic that had not been seen before the quote. He took photos of every step of the remediation and showed them to us. He discussed needs for remediation and completed it right away. He spoke to us before each step and asked for approval. His team, Omar and Herbert worked as hard and long as any team we’ve ever had for past home improvements. Everything was taken care of by the end of day two. The team made sure that everything was spotless and clean before they left. I’d like to commend Alex, Omar and Herbert for their strong work ethic and genuine politeness. They were trained in a way that calls for excellence. I had a lot of contact with Tim, who came out for the original quote and he never tired of explaining procedures to us. We are so happy with the entire team of Green Attic professionals.Description of Work: Blown in attic and garage ceiling insulation

They are great. Came in, have is a reasonable price. When they came, we didn't need what we hoped them for. They even found what our problem was, after 4 yrs fighting with our condo association and 9 HVAC guys. I will use them again, no doubt

Green Attic did a great job fixing all our attic issues (ventilation/insulation/mold) in our new house! Everyone we dealt with was friendly and professional from start to finish. Frank did a great job coming out and doing the estimate and Marian was very helpful at the office with scheduling/paperwork! The crew that came out to do the job was fantastic! Jaime, Jose Luis & Armando were very professional, showed me pictures as work was getting completed, answered all my questions and cleaned up everything when they were done. I would highly recommend Green Attic!

Requested attic sealing and insulation. They sealed, increased ventilation and blew in a blanket of insulation to R60. The value was very good and the install was also very good. I would not hesitate to use them again for other projects.

Green Attic was great to work with. It was easy to schedule a free estimate/inspection. Patrick came out and identified issues and gave recommendations. It was easy to coordinate a date to have the work done.

I appreciated the communication they gave before coming, including names of the workers. Alvaro, Romulo and Wilfrido were great. They were very respectful of my home and cleaned up all the work areas before leaving both days. Throughout the process they explained what they were doing and would often call me over so that I could see what they had done.

It was convenient to get the Nicor rebate through them and the follow up inspection they did really showed the difference the insulation and weather sealing makes.

Overall, it was a great experience. Even though it's only been 3 months since having the work done, I have already noticed a decrease in my gas bill when compared to last year and I definitely hear my furnace turn on a lot less.

The guys did a great job. On time, professional, and willing to adapt when circumstances changed. We discovered an electrical issue in the attic, so the team waited a few weeks to finish the job after I had those issues addressed.

Blown In Cellulose Benefits

Blown In Cellulose Benefits

Cellulose is superior to other insulation materials and benefits and cons must be considered separately on each home project.

 Most general contractors advise their clients to make the switch to cellulose dense packed walls
 Significant difference is sound absorption / sound control
 Improved heat retention
 Heat protection from radiation (direct sunlight)
 Fire retardant / fire safety
 Pest and rodent resistant
 Mold, mildew and moisture resistance
 Dense packed insulation fills gaps and voids otherwise left open with fiberglass batts
 Cellulose Insulation prevents sagging at the top of the stud cavity
 Cellulose Insulation all-borate, liquid fire retardant is infused directly into the fibers, resulting in a more effective insulator at the price of competitive blended products
 Cellulose Insulation Blown In is the best method of insulation without removing drywall
Cellulose insulation is good for your home and environment

Cellulose insulation is good for your home and environment

Cellulose insulation has a functional lifetime of more than 50 years!
Blown in cellulose insulation is produced primarily from post-consumer wood pulp (recycled newspapers), typically accounting for roughly 85 % of the insulation by weight.

Cellulose insulation is treated with fire-retardant. Borates and boric acid are used most commonly and account for the other 15 % of the cellulose insulation by weight.

Green Attic Insulation Can Help!

Viruses-icon

Mold Resistance

Cellulose significantly decreases the risk of mold even beginning to form. Thanks to its chemical treatment, mold doesn't grow on cellulose insulation. Cellulose insulation absorbs moisture, redistributes it and lets the attic/wall/ceiling dry in a controlled manner.
Bug-icon

Pest control

Cellulose insulation is pest-resistant insulation that is a great addition to your pest prevention plan. This insulation works on most common household pests such as cockroaches, ants, beetles, earwigs, silverfish, termites, etc.
Wind-icon

Air / Vapor Barrier

Air infiltration is almost as important as R-value in the thermal performance of a building. Infiltration of unconditioned ambient air means that heating and cooling systems must expend more energy to compensate for the infiltration.
Sound-icon

Sound Control

Cellulose provides very effective sound control to minimize outside noises and between rooms (if the interior walls are insulated). Many people only focus on the energy savings that can be achieved with blow in cellulose insulation but overlook the benefits that come from improved sound insulation. If you have ever walked into a house that is not insulated you will immediately notice that noises from outside of the house are “louder” than in an insulated home.
Fire-icon

Fire Resistance

Besides saving you money, cellulose insulation also provides extremely effective fire protection capabilities. Tests conducted by Underwriters Laboratories Inc.® show that Cellulose insulation provides an effective 1 hour fire rating. This will slow the spread of a fire allowing you more time to escape any danger. This is because cellulose is specially treated using Borate Compound Chemicals as a fire retardant in the manufacturing process to meet or exceed all fire safety requirements.
Energy-save-icon

Energy Efficiency

Cellulose insulation improves the energy efficiency of your home by reducing heat transfer, keeping your space cooler in the summer and warmer in the winter. With its high R-value, cellulose insulation helps to minimize energy consumption and lower utility bills.

Why Green Attic Uses Cellulose

Blow-in Cellulose Insulation is installed in empty spaces in the structural framing to slow down the transmission of heat out in winter and reduce drafts/cold. Cellulose Insulation is used to control heat flow for the following reasons:
Cellulose Home Durability Benefits

Cellulose Home Durability Benefits

Cellulose insulation effectively eliminates cold spots, which can lead to condensation issues and the subsequent growth of mold and mildew.

By preventing the formation of condensation, cellulose insulation safeguards the structural components and finish materials from staining and damage.

With its superior thermal performance, cellulose insulation ensures a consistent and comfortable indoor environment while protecting your property from the harmful effects of moisture.
Cellulose Insulation - Comfort Benefits

Cellulose Comfort Benefits

• Cellulose insulation creates noticeably warmer surfaces, effectively reducing uncomfortable chills and drafts caused by both radiation and convection.

By providing exceptional thermal resistance, cellulose insulation ensures a cozy and consistent temperature throughout your space, enhancing overall comfort and energy efficiency.

• Cellulose insulation acts as a reliable shield against overheating caused by excessive solar gains. By effectively blocking and reducing the transfer of heat from the sun into your living spaces, cellulose insulation helps maintain a comfortable and balanced indoor temperature.

Say goodbye to the discomfort of sweltering hot rooms and enjoy a cooler and more enjoyable living environment with cellulose insulation.
Cellulose Insulation Energy Efficiency Benefits

Cellulose Energy Efficiency Benefits

• Insulating with Cellulose = Results: never before seen instant monthly energy savings which costs less as prices rise.

• Cellulose Insulation Creates Air Trapped Between Layers and divides the air space to reduce heat transfer in winter from the living side and heat intrusion from the attic side in summer.
