5.0 Jan S. Greenwood Village, CO

I requested 3 quotes from 3 different companies. Guardian was not the least expensive but they were the most professional. We sat down and Brian (with Guardian) explained all of the work to be performed and what insulation would be best for our house. They came 5 days later and now we have an attic full of insulation just before a big storm. We couldn't be more pleased with the work.

1.0 Alex P. Arvada, CO

Provided the best price for spray insulation, but work completed did not meet agreed upon scope. The crew came back out and fixed most but not all issues. Communication of expectations was insufficient. The crew also removed breakers from my electrical panel without permission, cutting off power to parts of my home. I had to hire an electrician to inspect the panel afterwards and have not been reimbursed. Brian also misrepresented the available tax credits and utility rebates available for my project in order to make the cost more attractive.

5.0 Sarah T. Denver, CO

Quick response. Reasonable price. Did the insulation next day.

5.0 Gary M. Westminster, CO

Great deals, better service

HomeAdvisor allows Service Professionals to post information about themselves and their business on their profile. HomeAdvisor does not review or verify the information representations set forth in those profiles as they are self-reported by the Service Professional.

HomeAdvisor verifies state-level licensing where applicable - note: some states require local or county level licensing and you should verify whether or not your pro is properly licensed.

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.
