5.0 Bonnie S. Manchester, NH

We were in a very serious spot. My mother was ill and coming home to a damaged home due to no fault of her own. She had been trying to get help but as an elderly woman not much success. When we discovered her plight we contacted Jim from New England Decon and were immediately impressed and we did speak to 2 other firms however no one topped this company. They were professional, prompt, informed, concerned and got to work right away to solving our problems.

5.0 Mary S. Manchester, NH

NEDecon was quick to respond and upfront with their pricing. Rees Gemmel of NEDecon was personable and answered all questions with expertise and also gave smart advise. They did a great job on the basement decontamination. The workers were very thorough and performed their work as they promised. Thank you NE Decon.

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.
