5.0 Robert C. Cedar Knolls, NJ

The workers called before coming. They were very professional and knew what they were doing. They only had one mishap with the epoxy glue was spilled on the basement floor which was not really a problem because itâ s going to be painted. Johnny and his crew was great

5.0 Kathleen S. Forked River, NJ

My crew were highly skilled and hard working. They were also very polite and cooperative when I asked them to cover what my tenant needed to leave in the basement during the waterproofing operation. All the work was completed in the 2 days they promised. They cleaned up all the debris when the job was finished.

5.0 Mary B. Hampton, NJ

There was no project category that fit my job. Q1 insulated and encapsulated my crawl space. I especially like the "Turtle" enclosure for the entrance so it's easier for tradesmen to get in to work down there. Carlos and his crew were polite, informative and thorough. Thank you!

5.0 Octavia Z. South Amboy, NJ

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)
