Customers say: Quality work

"They were a little more expensive than their competitors but handled all furniture moving and cleanup. They weâ re very professional, worked quickly, but took the time to do the job right. And their solution worked: They applied foam insulation to the ceiling of my 3-season room which is now warm in the winter."

"Arc Insulation went above and beyond our expectations. Chris was such a pleasure to work with and was very patient with all of my questions and concerns. We did spray foam insulation and had several companies come out to give us a quote. No one seemed to have the knowledge or customer service Arc Insulation was able to provide. Luis performed the actual spray foam insulation and did a wonderful job. Our home is now night and day with comfort levels. We could not be happier with this company and will use them in the future for insulating our crawl space. I would recommend them to anyone looking to have spray foam insulation done right."

"It went really well. Robert Carroll really knows his stuff. Hire this guy. I say that without reservation of any kind. Don't look any further, believe me, I did. This is the smartest guy. He is honest, dependable, offers fair pricing, and his team can do all the work. I got several estimates from A+ rated insulation companies, but Robert was more knowledgeable than the other companies. He was the only one to point out that my soffits were not vented. Apparently, my house was built on the day no one was inspecting. The builder never cut open the soffits. That meant there was zero airflow going through my attic. The attic fan could run all day, but without air to move, it would not do any good. Only Robert noticed this and offered a solution to fix the problem! I asked some of the other A+ companies if they would vent the soffits and they all said they don't do that work, but they would be happy to add more insulation, which would not fix the problem if the attic was not vented."

"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!"

"We recently had blown in insulation installed in our home and couldn’t be happier with the experience from start to finish. The team was kind, professional and incredibly prompt. They showed up on time explained the process clearly and treated our home with respect. What really stood out was the pricing after receiving a much higher quote from another company their estimate was very fair and transparent with no pressure or upselling. It was clear they care about doing honest work at a reasonable price. The installation was completed efficiently, and the whole process was smooth and stress-free. I would definitely recommend them to anyone looking for insulation work great service, great value and great people."

"Very accommodating company. Responded to all my questions and concerns, treated my home with the utmost respect and left it clean. The room was a bedroom carpeted by prior owners. When I removed the carpet, it uncovered a nightmare. The room used to be part of the garage. The previous owners left the oil spills. dirt, and cracks and just covered it with carpet. Soooooo disgusting. Perma seal ground out the cracks, pumped poly foam underneath for support, sealed the cracks, ground them to level them, and it even looks like they tried to clean up the disgusting oil spills left by previous owners. (I'll be doing additional scrubbing). I will wait for spring thaw to assess its waterproofness before I order my new floor. See before and after shots."

"The team sealed our attic, added attic chutes, terminated two bath exhaust fans via soffit, built boxes around our recessed lights and blew in insulation. They tested air leakage before and after with positive results. We notice a difference in furnace cycling (gone down despite artic temps) and upper level of home is more comfortable. They worked hard and did a good job cleaning up after themselves."

"While removing the old roof, the aluminum coverings on our mansard roof dormers were damaged. The roofing crew attempted to repair the damage but the result was not satisfactory. As compensation they deducted a small amount from the total bill."

FAQs for spray foam insulation projects in Chicago, IL

Local and federal rebates are available for insulation installation, which can significantly reduce your overall costs. Many utility companies offer incentives or rebates to homeowners who improve their home's energy efficiency. Contact your local energy provider or government agencies to learn about available programs in your area, and consult with a professional insulation installer to maximize your savings.

It's not necessary to remove old insulation before adding new insulation, as long as the existing insulation is in good condition—dry, free of mold, and not damaged. Adding new insulation on top of old insulation can improve your home's energy efficiency by increasing the overall R-value. However, if the old insulation is wet, moldy, or damaged, it's best to remove it before installing new insulation to prevent potential health risks and ensure optimal performance.

Insulating a house takes between five and twelve hours for batts or boards, and two to five hours for spray foam or blown-in insulation. The exact time depends on the size of your home, the type of insulation, and the accessibility of the areas being insulated. Keep in mind that projects may take longer if old insulation needs removal, if there's a larger square footage, or if spaces are difficult to reach.
