I had a really bad experience with MTC. They misdiagnosed my mold problem and told me I did not need remediation when in fact I did. Instead, they directed me to pay $1000 for a DIY fogging kit to do myself at home which did not work- even after I hired a professional to do it from their company. On top of the $500 I paid for the initial testing, $1000 for a kit, and another $500 to re-test everything, I was back at square one with no solution or results. I now had to hire another company to start over and pay them another $500 for a proper inspection, to then find out I have to pay 5k in remediation and repairs. I lost over $2000 going with MTC, and they only refunded me $189 for the wrong diagnosis all the frustration and the time lost. I highly recommend going elsewhere.

David was awesome, very knowledgeable and he explained every step of the way. My son has autism and David was super nice and answer all his questions about his equipment and the process of gathering samples.

4.5 Margo L. San Diego, CA

David who did the inspection was punctual, extremely knowledgeable and efficient and spent time explaining things to me. When my results came back much time was spent explaining what the outcome was and how to remediate. The company is very responsive to phone calls and ready with advice

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.
