Great job

5.0 Scott H. Pleasant Hill, CA

We are so pleased with the work done by Cesar and his team. The work proceeded quickly and with great attention to detail. Everyone was professional and provided answers to all our questions. Cesar was hands-on. You could tell they enjoyed their work. And the price quote was more than satisfactory for our complex project. We recommend CEL Insulation for any project of this kind.

Great company with reasonable prices.

5.0 Antonio S.

Great company with great customer service. They were really professional and personable with everyone. I did a bit of research and got some additional estimates. Still very, very happy with their work. They were respectful of my property while doing the work. I most definitely will continue to hire and I highly recommend.

0.50 Paul I. Fairfield, CA

his quality of work was good. they worked fast got the job done in one day. but there clean up skills need some work. they left little bits of insulation in my back yard that I need to vacuum up with a shop vac so my dogs wont eat it. I was quoted one price to do my attic and walls. but it turned out that 4 walls already had insulation in the walls. when measured would be 40 to 45 feet of wall that he did not have to drill, insulate or patch the holes and he only took off a hundred buck off of my bill. he is a nice guy and hard working but needs to work on his clean up skills and his pricing if he doesn't have to do the whole job. would I recommend him yes if you do batt insulation and I would have to say no on the blown in insulation. UPDATE: 4/19/2017 well I really didn't want to do this but after I found empty wall cavities that were supposed to be insulated with blown in insulation by this company. I just had to update my review of them. it's been a year since we had this guy do blown in insulation in our house. and today 4/19/17 I cut a hole in my wall to run some wires and there was not insulation in the wall cavity. I am very disappointed with this guy he did terrible work now I am wondering how much of my house he actually insulated. STAY AWAY FROM THIS GUY

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.
