Richard Gray is your trusted mold professional. The quality of interior air can affect the health and comfort of your home. In coastal California indoor air quality problems can arise from moisture, insects, pets, appliances, materials used in household products, furnishings, building materials, smoke and other sources, all of which affect your indoor air quality and become a health concern. Our goal is to continue as early adapters in the extremely fast developing science of clean indoor air quality, mold removal, mold testing, pest control, and high heat structural pasteurization. We look forward to providing you with a clean and safe environment.

Review by
Project: Test for Toxic Materials & Mold
Richard Gray and his daughter Jayce, also a certified environmentalist, were punctual for our appointment and very thorough with sample testing and air quality testing. They were very patient in explaining their process and answered all my questions without hesitation. I would highly recommend them to anyone seeking air quality testing and mold abatement.

Review by in Los Altos, CA
The testing procedure seemed very perfunctory.
Response by Certified-Environmental: There is always a person that is not happy, we are sorry. We do every inspection and test in order to certify the home healthy. Nothing perfunctory.

Review by in Los Gatos, CA
Excellent, professional, immediate service. I would highly recommend Certified-Environmental for mold testing. They called me back same day and even made time to come do immediate testing on toxic mold. The certified professional team worked well together and spent a long time in my home where they discovered other areas of mold which I never thought to look. Hardworking and honest. They have very reasonable prices. They will only test what they believe is nessessary. The team is extremely knowledgeable in so many areas. They go out of their way for their customers. Certified-Environmental really cares about their customers and it shows. They kept in contact with me all the way through the mold remediation process. The 3rd party certified testing lab provided extremely through results which Certified-Environmental explained in detail to me in their findings report. Quick 2-3 day turn around time. Certified-Environmental got us out of an airborne toxic mold home. My family and I are truly so grateful! 5 Stars!!!

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.

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.
