We know top-quality insulation, but don't take our word for it, check out what local homeowners are saying about Assured!

From the estimate to the installation your guys were on time, polite, and professional. I was very happy with the attention to detail in the work yesterday. Luis and his guys did a great job.
Everyone always says it, but they really did treat my house like it was their own house.... Read More


Marvelous job!  They also found duct work damage in my attic and repaired that for me.  I’m very happy with the work done!

Kathy B.

Wonderful job!  Craig was prompt for the estimate.  The installers were 5 minutes early for the install and very efficient.  I’m very pleased with their work!

My wife and I were totally surprised as to the thorough job they did as well as the care and consideration of being in our home. Very impressed with your operation.

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!!!

Anthony B.

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.

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.

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.

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.

In 2015, Assured Insulation insulated my 2300 square foot Illinois home through the Ameren Act on Energy Program.  I also got a  new furnace and central air through the program.

Stacey W.

The crew was efficient and cleaned up after themselves well.  We are pleased with the insulation work and would recommend them to anyone.

Todd M. - Illinois IL

Thank you! The guys were very professional & treated our home with care. I anticipate that we will notice a marked difference in our comfort level & our heating bill as well this winter. Also, hopefully, no more ice dams & icicles should be a problem! I will keep you posted!

Mrs. Tolbert

What a AWESOME crew you have!  Denise Bobby and Dwayne were professional, cordial, efficient, knowledgeable, patient, and personable! I felt comfortable with asking them questions and trusted their expertise!

Your crew did an excellent job. Crew was very professional and already felt the improvements in our house immediately.

Project: Install or Upgrade Blown-In Insulation: these guys came in and did their job the way they said they would in no time flat with no mess at all and no fall throughs and I even checked the job afterwards and no complaints, I would recommend them to anyone. Thanks.

Don M. on 10/02/17

Work involved air sealing, bath vent duct installation, installation of baffles, and adding blown insulation in attic; great to work with on scheduling; work crews arrived on time, were very thorough and professional, completed the work in less time than estimated, and cleaned my house...

Assured arrived as scheduled & provided all agreeded upon work in a timely and professional manner. They left the work area very clean. Thanks guys!

Very professional gentlemen. Always working! wouldn't know that they were there. all members of the crew had very good work ethics. Answered all of our questions.

I had a family of raccoons in my attic that took over 3 months to

insulation had to be removed (combination blown in and rolled

The guys did a great job.  The crew was very tentative and explained everything they were doing.  The guys were very polite and hard working.  I would definitely recommend our company to someone who is looking for this type of work.

Joe T.

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.

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.

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.

The job went off without any problems at all. The crew called me whenever they switched to another building/property which I appreciated very much. I also had no complaints from the tenants which is appreciated!!

Mike H.

The install went good and no complaints. The crew at Assured Insulation was very nice and got along well with all the tenants!


Install was excellent! The guys were first rate, professional, and knew exactly what they were doing. I am very pleased.


The install went great and the guys were great to work with. No complaints here!

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.

Ann T.

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.

Everything went very smoothly thanks to the Assured Insulation crew!


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

Mike L.

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.

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.

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.

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!!


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.


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.


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...

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.

Mike B.

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.


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.

  • My wife and I were totally surprised as to the thorough job they did as well as the care and consideration of being in our home. Very impressed with your operation. There was a ton more involved than we ever thought as well as the science behind it. And we used to do blown in insulation a number of years in my family’s business. Big difference in what we used to do as now. Great job!
