The project manager Bryan Zailer came and gave me the solution and quote for my insulation project which was very objective and competitive. Bryan himself seems very experienced and extremely responsive in communication. He promised to finish work before some date and delivered 100%. I would definitely recommend them.

Tri-County was prompt and completed the job with no problems. They were happy to give advice and explain the job in detail. We have used this contractor several times and always with good results.

4.0 Robert S. San Jose, CA

Job was performed as promised, but in process installer stepped through ceiling causing a large hole about 3x3 ft. over family room. Temporarily fixed, but not finished. Withheld some of the original estimate funds until ceiling is completely repaired. Promised to follow up with another contractor. Insulation was blown in per specification. Have not had time to evaluate the savings in energy costs. Communication between the original estimator and installation crew was lacking some information previously provided. Asked for an afternoon appointment, but came in the morning. Did not matter however, as this was a holiday.

5.0 San Jose, CA

We are very pleased with the work. Hardly any mess with the insulation to clean up. The guys put everything back that they had to move out of the way from the walls. Great job.

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
