Review by in Brookfield, IL
We have 2 attics, an upper attic and a lower attic and the upper attic is not accessible. They insisted they could access it, and cut a hole in the closet and in the roof (without telling us). When doing the work, they told us that they could not access the upper attic. They asked if they should just spray foam into the hole in the closet. I said no because they wouldn't be able to see where they were insulating. Later, when it began to rain, my son called the company and the salesman said the leaking wasn't their fault. The salesman did then transfer my son to the owner who was rude and insulted my son. We had the roof replaced the summer before this and the roofers had taken pictures of their work and we were able to get those pictures and send them to the Better Business Bureau to show that the hole was not there in the roof. Through the Better Business Bureau, we were able to have the repairs for the hole cut in our roof repaired, and after some difficulty, the hole in the closet patched and repainted. The whole situation was a long and painful experience and I would not recommend this company to anyone.

The crew arrived ahead of scheduled time and were very quick and thorough. They asked me to inspect the finished work and then cleaned up after themselves, inside and out. Great service provided.

Review by in Carol Stream, IL
Workers were very nice and professional. Also, sales person (Gary) was nice and reliable. Job was done timely and at good quality. The only downfall was dealing with the business owner (stressfull experience).
Response by Illinois Insulators, Inc.: Was not trying to be stressful the problem was. I had 0 reception on my cell phone. when she had questions we went back and forth about 5 times with being disconnected. I already apologized for that. She had questions while the job was in progress I was dealing with projects in Coal City that had tornado damage from 2 months ago. Just an issue at Sprint And timing

Review by in Oswego, IL
They gave me a quote the same day they inspected the attic. They were on the job the next day(on time). Two workers completed the job within 2 hours. They cleaned after their work was done. They made sure I inspected their work. It was a great experience. I wish all jobs were that easy to complete.

Raccoon damage in our Attic. Workers started the day by preparing the house with tarps to cover the carpeting where ever they would be working. As the work progressed they informed me of the findings in the Attic. Removed the old insulation, De-sanitized the attic with special non-harmful chemicals, then laid 11R batt, then blew in R49. Can't wait to see the real results next winter. Workers were well trained and pleasant, they cleaned up afterwards and left the house neat & clean, just like it was when they arrived. I would recommend this company to my family & friends. Thanks Gary & Illinois Insulator team, appreciate your prompt service.

Seal of Approval

What is the screening process that Service Professionals go through in order to become members of the HomeAdvisor network?

  1. Verify Trade License
    HomeAdvisor checks to see if the business carries the appropriate state-level license.
  2. Verify Insurance
    As a part of our screening process, we encourage professionals to carry general liability insurance. We require coverage for hundreds of services.
  3. Verification of State Business Filings
    For business types that require a Secretary of State filing, we confirm that the business is in good standing in the state in which it is located.
  4. Criminal Records Search
    HomeAdvisor uses 3rd party data sources to conduct a criminal search for any relevant criminal activity associated with the owner/principal of the business.
  5. Sex Offender Search
    We confirm that the owner/principal is not listed on the official state Sex Offender web site in the state in which the owner/principal of the company is located.
  6. Bankruptcy Search
    We use 3rd party data sources to check the history of the principal/owner of the business for bankruptcy filings by or against them.
  7. Legal Search for Civil Judgments
    We use 3rd party data sources to check the principal/owner of the business for state level civil legal judgments entered against them.
  8. Liens Search
    We use 3rd party data sources to check the principal/owner of the business for liens placed against them.
  9. Identity Verification (SSN)
    HomeAdvisor verifies the social security number(s) of the owner/principal for identity check purposes. This check applies primarily to smaller business entities.
  10. Identity Verification (Reverse Phone Lookup)
    We conduct a reverse business phone lookup to identify records matching the phone number information provided by the business.

NOTE: Member service professional information confirmed as described above may change or expire over time; while HomeAdvisor attempts to maintain accurate and up-to-date information, and confirms changes when notified, we cannot guarantee that profile and screening information is accurate. Therefore, we recommend that before working with a service professional you verify that information presented is still current and/or acceptable to you.
