Let me start off by saying Im super impressed with the install crew Malik, Andy, and Brian. This crew is very professional, personable, and works REALLY hard! Please be sure to convey this to whoever is in their up-line as they each deserve kudos for being great employees and representatives of Groundworks. I was also VERY pleased with our estimator Zaire, he spent a lot of time planning and adjusting to our needs/wants for this project. Very communicative. I highly recommend Groundwork?s!

We cannot say enough good things about the help and care Ernest Vigil gave us from the start of our crawl space project to the end. He returned our calls and emails promptly and helped guide us each step of the way. He went above and beyond when a problem arouse to find local help to quickly come out to help address and fix the problem. Mathew from Puget Sound Water Rescue one of the local company is a good company to have on call. And your team members from Georgia were outstanding. We have several neighbors who have watched the care and quality we received with ground works and have said they will be the first company they will call when they are ready to have work done on their homes. Thank you, Ernest and the rest of your team for treating us like you would a member of your own family. It has been a pleasure working with you. Cindy and Alan D.

Matthew came out for our annual inspection and servicing this morning. He showed up on time, was professional, polite, well spoken, and worked in a timely fashion. He did an excellent job of explaining the results of the service, as well as giving us a detailed estimate on repairing our concrete in the future. Overall, Matthew's work was top notch and I'd give him a 5-star review. Thank you!

Wyatt, Zane, Tucker and Oliver were fantastic. Customer service was fantastic and they finished their work quickly and professionally. I'll definitely be recommending and contacting for any drainage needs down the road.

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.
