Schyler arrived at the appointed time explained the the process and how the equipment worked. After he finished he walked me through the completed work. He had cleaned up all the leftover residue explaining if there was any further movement in the work there was a five year warranty and he would return to correct it at no additional cost.

Response from Company:

We?re glad to hear Schyler provided clear explanations, showed up on time, and walked you through the completed work?that level of communication is something we take seriously. It?s also great to know the cleanup and final walkthrough met your expectations. Thanks again for your trust, Bob!

They got it right to the best of their ability with the budget I had available to work with. My expectations were met 100 percent. Did they correct 100 percent of my 60 year old foundation? They did the best they could exceeding my expectation and then returned money that I thought was spent because they found a clever way to save some time once they got here and were in the middle of the job……the core of who they are reveals their honesty and they returned thousands of dollars. That was fresh and unexpected…..word!

Response from Company:

Thank you for sharing this, Matthew, it truly means a lot to our team. Every home, especially one with a 60-year-old foundation, comes with its own challenges, so our goal is always to deliver the best possible solution within the budget available. We?re glad to hear we not only met your expectations, but exceeded them. Your note about honesty and returning unused funds is especially appreciated. That?s a core part of how we operate?doing what?s right for the homeowner, even when it?s unexpected. Thanks again for your trust and for recognizing the integrity of our team!

We had a complete encapsulation of our crawl space and sump pump and humidifier system installed. The young men who did the work were very professional. Antonio was the project manager and he was fantastic. Answered questions, explained the process, and made sure we were ok with what they were doing. They showed up at the time designated and called if they would be late. Communication was very good. Shout out to his helpers, Daniel, Jesse, and Kameron. At the end of the project they cleaned up the workspace and made sure things were left like it was before project. Thanks guys.

Response from Company:

Thank you so much for taking the time to share your experience?we truly appreciate it! We?re thrilled to hear that you were happy with your crawl space encapsulation, sump pump, and dehumidifier installation. Antonio and his team?Daniel, Jesse, and Kameron?take a lot of pride in their work, and it?s great to know their professionalism, communication, and attention to detail made a positive impact throughout your project. Showing up on time, keeping you informed, and leaving your home clean and respected are all things we strive for on every job, so your feedback means a lot to our team. Thanks again for trusting us with your home!

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.
