Great service

5.0 Tangie W. Carpentersville, IL

The were very helpful and took the time to go over the findings in their report with me and answer any and all questions. They were very attentive to my needs and addressed my concerned. They were also very empathetic, great team work.

4.5 Gail P. Marengo, IL

Dave and his son were so nice to talk to and explained everything. Very fast service! I found it to be a little expensive as I'm retired but knowing if the air I'm breathing is ok is very important to me too

5.0 Chris B. Lake Geneva, WI

They came on time and even had a feature where I could track their vehicle (great to know when I have a dog I need to put away and a child to keep busy) they were not only timely, but very knowledgeable. I will have them back in a few weeks to test again

5.0 Leshaun L. Palatine, IL

From the very first conversation with Dave I knew I was in good hands. He is passionate about the work they do and his customer service was excellent. I got updates of the work and process from beginning to end. I also appreciate when companies educate you on what causes the issues and ways to prevent it Dave did that. I have this company saved in my contacts for when I may need them in the future and for referrals. If you go with this company you will not regret it. Very happy customer.

5.0 Alice K. Barrington, IL

He performed lead swab test along with the air quality test. You need to wait about three days to get results for the air test from a lab. Great customer service, mr. Gardner was responsive and explained everything from the report.

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.
