Rigo and Wilfredo added insulation to exterior walls in two upstairs bedrooms.  Both hard workers who explained the process and answered all of our concerns and questions.  We were glad to have this crew in our home.  Wilfredo said someone will call before coming tomorrow to do the finish sanding.

Romual and Jose it’s -10 and they were here on time. Hooked up power. Protected and covered all carpeting, walls doorways etc told me it’s going to be dusty with plaster walls and 6 hours later they are Cleaned up and gone. Total 420 sq ft blown in insulation into 4” dead air space in this 1910 house.  Green attic has done my attic and now perimeter walls



Highly recommend this team.

Romulo and Jorge from Green Attic were amazing. They worked extremely hard all day installing our installation and provided the best possible service. They communicated well and went above and beyond. They additionally did a great job cleaning up at the end of the day. Couldn’t recommend them more!

I hired them for attic insulation and air sealing. Their quote was the best I got and they were thorough. The estimate was done by Frank, who was very thorough and helpful in identifying areas that needed to be finished - he asked about how many bathroom fans we had upstairs and I totally forgot about one that needed to be installed! The crew worked efficiently, answered my questions, and showed me the attic when it was done. I had done some research before about what kind of work needed to be done and it all looked great. If I had another attic, I'd hire them again!

Romulo and Mario did a great job in doing some minor blow in cellulose work in our home. The job was done cleanly (within reason, it's still construction). They were tidy and efficient. Time will tell if the work was effective, but given what I saw we should hopefully be much warmer. Strangely, looking forward to a very cold day.

Jose and crew were great! He clearly explained the process and all the work that would be done. They blew insulation into our attic to the proper level and cleaned up everything before they left. Overall, they did an excellent job.

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

This company is really amazing and I highly recommend them! From the initial sales experience with Patrick (no nonsense, honest, detailed and great communication) to the workers including Julio who took a lot of pride in his work. It's so refreshing to deal with a reputable company that has high standards and ensures quality service. I'm glad I went with them!! Amazing work!

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.

Surface Temperature Differences Create Condensation When Vapor Passes Through

Temperatures differ between interior and exterior, these temperatures bring vapor in the form of moisture.

This is a common example of window condensation in winter. If the window is wood ( organic surface) it can easily be affected by mold and eventually rot.

Keeping the surface temperature above dew point will help reduce condensation. Common locations for condensation are:

Attic Can Lights
Cathedral Ceilings
Bath Fan Exhausts
Bedroom Windows
Cutaway of a house in winter illustrating condensation and vapor movement
Condensation on roof sheathing causes mold growth

Condensation On Sheathing Contributes To Mold Spread

Interior moisture can reach outside sheathing and create condensation.

The Dew Point is the temperature at which this water vapor being held in the air condenses into a liquid. So, higher relative humidity the closer the dew point will be to the temperature of the air.
Attic ventilation with proper airflow through rafters and insulation

Dehumidifiers & Ventilation

For more comfortable and consistent indoor temperature control, optimum energy efficiency, insulation does well, but it leads to another problem humidity relative to outside temperature and air flow.

Imagine a cave with no wind or breeze, no sunlight, and no air movement, it would be wet, damp, soggy, moist year round; now imagine just the opposite, a healthy ventilated sunlit fresh air temperature controlled room.

Vapor Barrier: Advanced Moisture Control

The Vapor Barrier should be on the warm side of the room in Chicago winter’s, but the location of the vapor barrier varies in other climates around the US.

Air should not pass through the building envelope into the wall cavity through unintentional gaps on the buildings envelope. A Sealed Cavity is essential and supplemental to insulation.

Does home contain vapor barrier and ventilation?
