4.0 Fred B. New Hartford, NY

Terrafirma was excellent and made sure the job was done correctly before they left. Despite a failure of communication they made sure it was corrected. No complaints. Not cheap, but absolutely worth it. Talk to the boss if you have questions.

4.0 Mivhael H. Graham, WA

Professional, courteous, knowledgeable. They did exactly as their proposal laid out. There was no mess; the job was completed quickly. I had 3 bids for the work; they were $700 & $1400 cheaper than the other two companies.

5.0 Pam W. Saint Helens, OR

Very efficient, thorough and took the time to show me tons of pictures of the underside of my house. Great explanations of why they choose to do certain things.

2.0 Nikki B. Portland, OR

These guys will promise you anything to get you to sign on the dotted line. They say they can level a sidewalk with their filler. I found out the hard way that this is not true. They worked for days filling underneath my sidewalk with God knows what and the sidewalk never budged. Doh on me. They are very expensive, especially when all they ended up doing was grinding the sidewalk down where it was higher. I tell everyone who is thinking of using these guys to level anything to beware.

5.0 Joseph C. Tacoma, WA

A wait to get them scheduled but we'll worth it

5.0 Stephany L. Beaverton, OR

Don from the Tigard TerraFirma was informative, professional, experienced and thorough.

Response from Company:

Thank you! We will pass this on to Don as well!

4.5 Bill L. Renton, WA

$20k for a crawl space encapsulation with a three-pump sump system is a lot of money. Too much? I am not sure of the four companies that came out, only TerraFirma gave a quote.

On the Job

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.

To find more licensing information for your state, visit our Licensing Requirements page. Note that some states require local or county level licensing and you should verify whether or not your pro is properly licensed.

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.
