5.0 Wayne C. Fort Collins, CO

Jose and his son arrived punctually to do the agreed-upon job at our rental property. They were incredibly industrious and finished the wall installations in a short time, then went to work on the attic. The price was very competitive and the level of attic insulation was more than we had expected. We will hire JCJ Insulation again for similar projects.

5.0 James M. Denver, CO

Jose and his son were excellent. Responded quickly, scheduled the work promptly, great price, and performed high-quality work insulating my basement crawl space. Without a doubt I will be using him again in the future to provide blown in insulation in my attic.

5.0 Kara H. Denver, CO

Jose was very on top of reaching out to me and was able to provide a quote the same day and return to complete the work the following day. We had originally submitted a request to have blown insulation in our attic, but Jose, was incredibly helpful and transparent in determining we had good insulation already. He was then able to install some batting in our crawl space to help insulate some exterior concrete walls. He was reliable, friendly and price was very reasonable. I would highly recommend his services.

5.0 Jim H. Boulder, CO

Jose made a prompt visit to give me a quote on my request to add blown-in fiberglass to improve heat conservation in my attic. The quote was very fair and considerably less than another company. He scheduled the work to be done a few days later, arrived on time, worked efficiently, doing a fine job, and finishing at the predicted time. He cleaned up well after the job. I would recommend this company for anyone needing insulation installed.

5.0 Patricia L. Denver, CO

Jose from JCJ Insulation just completed installing attic insulation for my older home. He was prompt, responsive, efficient, cleaned-up the project well and the price was definitely right. I would highly recommend this company.

Jose was fast, friendly and affordable. Highly recommend!

5.0 Jim G. Thornton, CO

Jose was courteous and prompt to respond to my request for an estimate and scheduled the work immediately. The bid was extremely reasonable and the workmanship impeccable! Insulation can get messy but they did a thorough clean up afterwards. Professional in every sense, I'd gladly hire them for another project!

5.0 Steffie S. Longmont, CO

Jose called and finished my project the same day. He is great and works very hard. His son is also a hard worker. I appreciate his timeliness and quality of work. Thanks so much.

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.
