Test for Toxic Materials & Mold

Shannon was professional, knowledgeable and pleasant. He answered calls promptly and followed up on the progress of the project after his portion was completed. Hopefully, I'll never need his services again, but I would call on him should the case arise; and I would definitely recommend him to anyone in need of environmental testing.

Test for Toxic Materials & Mold

Shannon was fantastic. He explained what he was doing and how it the whole test works. He even suggested another contractor for the job of cleaning up the mold after the testing. I would definitely recommend him for home testing. He did an amazing job!

Find More Pros

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.
To find more licensing information for your state, visit our Licensing Requirements page.

HomeAdvisor's Screening Process

HomeAdvisor uses an extensive screening process to screen businesses and business owners/principals. We perform this screening when a business applies to join our network and, if the business is accepted, whenever concerns are brought to our attention. If you have concerns that a pro in our network doesn't meet these standards, please contact us to investigate. We're committed to maintaining a network of trusted home service businesses, and those who don't meet our criteria will be rejected or promptly removed from our network.

Criminal Background Check

Who does HomeAdvisor background check?

The owner or principal of each business in HomeAdvisor's network (with the exception of Corporate Accounts) must pass a background check. Unfortunately, we cannot perform a background check on every employee of a business—the background checks are performed only on the owner or principal. As always, we recommend that you conduct your own research on the businesses you hire, including making inquiries directly with the businesses regarding their employee background check policies.

What does the background check cover?

We use a third-party vendor to conduct a criminal records search in the state in which the business owner or principal works. Our third-party vendor uses a national criminal database ("NCD") to screen service professionals. Businesses will not be admitted to the network if their owners or principals have the following felonies in their available criminal records*:

Arson

Assault/domestic violence/battery

Child abuse

Intimidation/terrorist threats

Kidnapping/abduction

Lewd and lascivious behavior

Manslaughter/murder/homicide/vehicular homicide

Rape/incest

Robbery/carjacking

Sex offenses

Other felonies not listed above that occurred in the past seven years

Contracting without a license in the past seven years

Our background check does not exclude service professionals unless the crime at issue is a felony.

*The comprehensiveness of the NCD varies by state. Please be aware that the reporting in the NCD is particularly limited in the following states: AL, CO, DE, GA, ID, IL, KS, LA, ME, MA, MI, MS, MT, NE, NV, NH, NM, SD, UT, VA, VT, and WY. After initial admission to the HomeAdvisor network, businesses are re-screened biennially.

How is COVID-19 impacting the HomeAdvisor background check program?

Due to the coronavirus pandemic, several government agencies and courts across the country have temporarily closed their offices. While HomeAdvisor will continue its background check program to the extent possible, these closures could prevent some background checks from being performed. Please be advised that, during this period, if we could not perform a background check, HomeAdvisor will allow the business into the network and match the business to consumers. As affected government agencies and courts begin to re-open, we will resume our program in those jurisdictions. As always, we encourage consumers to perform their own research, to the extent possible, before hiring any business.

Licensing

We verify any applicable state-level licenses, and we require every business to attest that they carry the appropriate local licensing to practice their trade. Please note that HomeAdvisor does not confirm local licensing. Do your own research using online ratings, reviews and through phone interviews before hiring a company.

Corporate Accounts

Some businesses are employees, franchisees, dealers or independent contractors ("Corporate SP's") of larger national or "Corporate Accounts". When this is the case, we may match you with the Corporate Account or with one of their Corporate businesses. The above screening process does not apply to Corporate Accounts, as HomeAdvisor does not screen Corporate Accounts or Corporate businesses.

Verify Trade License HomeAdvisor checks to see if the business carries the appropriate state-level license. Verify Insurance As a part of our screening process, we encourage professionals to carry general liability insurance. We require coverage for hundreds of services. 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. 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. 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. 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. 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. Liens Search We use 3rd party data sources to check the principal/owner of the business for liens placed against them. 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. Identity Verification (Reverse Phone Lookup) We conduct a reverse business phone lookup to identify records matching the phone number information provided by the business.

NOTE: Member service professional information confirmed as described above may change or expire over time; while HomeAdvisor attempts to maintain accurate and up-to-date information, and confirms changes when notified, we cannot guarantee that profile and screening information is accurate. Therefore, we recommend that before working with a service professional you verify that information presented is still current and/or acceptable to you.
