5.0 Hiroshi N. Stevenson, MD

Overall a great experience. Highly recommended. Tim was prompt, professional, and courteous. He was considerate of my elderly parents health conditions and conducted the test quickly and discreetly. He answered my questions prior to the test and even answered follow-up questions I had. Will share with my friends and family.

5.0 Renee L. Falls Church, VA

On time and professional

5.0 Bruce C. Silver Spring, MD

I would have given Tim even higher marks if i could. He did testing at two houses I own. very service oriented, Even fitted my place in on the 4th of July when I explained there was an urgent need.Very polite friendly professional demeanor . Clear reports that I feel i can trust. Reasonable /low cost compared to others. You will not go wrong with him.


Tim came promptly and took samples. He turned the report around in less than a week. We appreciate his timelines.

5.0 Drew H. Falls Church, VA

Great experience with Tim. He was recommended by a friend and I'm happy I listened. He not only shows up when he says he's going to - he was even a few minutes early. Very refreshing to have a contractor be prompt and such a good communicator. Job was done efficiently and thoroughly. Also, I priced out multiple contractors for the same job and Tim's prices were better. If I ever have the need in the future I will call him again!

4.0 Robert L. Mclean, VA

Prompt and knowledgable.

5.0 Natalie G. Woodsboro, MD

Tim was super responsive and thorough. I have mold illness and needed specific to follow a specific protocol while buying a new house and having it remediated. He was very diligent in learning from me and educating me, willing to go the extra lengths and super accessible. I highly recommend him and will use him again for maintenance testing. He knows his stuff!

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.
