  • Abel, Dwayne and Lewis were so personable and very polite, all around great guys, just like the assessor, Tim, who came out and gave us our estimate. They answered every question we had and learned a lot from them.

    James S.
  • Abel and Dwayne came to our home yesterday. They were two great guys who went out of their way for us.There were a few ducts that were not connected, that I could not see, and they had fixed it with no problem. They were willing to give good advice and our installation went very well.

    Ron G.
  • The two gentleman who represented your company, were the nicest, sweetest, most polite and respectful guys that I have had in my house in a very long time. They were very thorough and very easy to work with.

    Mike H.

  • No complaints or concerns about the install. Everything with the Assured Insulation crew went smoothly in Effington, IL.

    Mike L.
  • Assured Insulation Solutions insulated my home last week and I had to write to tell you how much we appreciated the crew and the work they did. We are elderly and nervous about strangers in the house, the crew was very clean, very polite and pleasure to have in our home.

  • Once again, Adam and the crew did a great job. However I more impressed with these young men's conduct. They know their stuff, they work hard and they have impeccable manners. Thanks for working so hard to have good employees.

    Tim Calvert
  • I had an install done in late March of 2015 and I just wanted to let you guys know that I am so impressed with the work done by your crew.  Adam and the crew were really on top of the job and all your guys worked hard, were polite and explained what they had done.  On top of that they left my...

  • Adam, Dwayne and Anthony did a great job, were courteous and respectful… preformed their duties to my satisfaction.    Now… I will watch my utilities shrink during our upcoming winter.

  • Good Morning Cal & Jeannie, I just want to send you a big thank you! I want to say that your crew did an outstanding job yesterday when doing the insulation & air sealing on our home. Your crew was very polite and did a great job. They worked together well.

  • Hello, I just wanted to say I had my home insulated by your company, and I am so glad I did! I am so excited to know my home will be using less energy.  Also, your crew was professional, neat, and nice to my cat!  I cannot say enough good about them.  Great job!!

  • We have struggled with a cold room over our garage for years. We paid several other “professionals” to come out to our home and try to fix this problem, none were able to solve the problem until Assured came out and evaluated our insulation and heating system.

    Debbie B.
  • We had no idea how having our home properly air sealed and insulated would improve the comfort of our house. We have lived in our home for years and had come to expect high utility bills and some uncomfortable rooms.

    Bruce S.
  • I had Assured Insulation Solutions come to my home and replace the furnace and provide some additional insulation in the attic and walls. I found the crew to be very knowledgeable, polite, and professional. They even fixed some water leaks that were not on the work order.

    Bill Y.
  • After Assured insulated and air sealed my attic, my energy bills decreased over 30%! I could not believe that the relatively small investment is having such a dramatic return in savings. In less than one year, I saved more in utility bills than I paid for Assured to do the work.

    Heidi R.
  • When I walked in the home after Assured was done with the work, I could immediately tell the difference. After checking my utility bills for several months before and after the work, I am thrilled to report that I have seen a substantial reduction of my utility bills.

    Tony D.
  • Had to write you a note as to the positive results of the sealing and insulation job you did for us. For the first time in the 13 years we have lived here, our house is comfortable from top to bottom.

    Mike K.
  • I thought I should tell you that I'm very happy with the work your crew did at my home yesterday. They were very polite. They did a great job and made sure that everything was clean and in order before they left. Thank you.

    Florence T.
  • It's 14 degrees outside and balmy inside our house now. I am tempted to wear a Hawaiian shirt and pair of shorts. Really, it's quite a change from before.

    Ian M.
  • The Assured crew were terrific!  They were very informative and professional.  They cleaned up after themselves and it was such a simple and easy process.  They did an awesome job.

    Happy Customer
  • Dwayne was a great leader!   All of the crew were very professional.  They made sure everything was clean before they left.  If I could,  I would use your company over and over again.  They were all pleasant to work with and very respectful.  I was overly pleased from beginning to end.

    Graham - Naperville
  • Recently we had Ed, Dwayne and Abel do insulation work for us.  They were very courteous, friendly and professional.  I would call again if we needed work done.  5 Stars!!!

    Todd M. - Illinois IL
