5.0 Brian C. San Jose, CA

I am in the process of building a separate standalone home office on my property. Mercoza was an excellent choice to pour the slab foundation. I was working with Jason and he was quick with his quote, and very fast to reply with any questions or inquiries I had. After getting a few quotes for the job I decided to go with Mercoza and I am very pleased that I did. Once I spoke with Jason on choosing them for my job, they were at my house three days later! They prepped the site, and poured a beautiful concrete slab. The job was completed in one day and I couldn't be happier with they way that it looks. I will absolutely go with Mercoza for any future concrete work that I have!

The concrete work was top-notch, and the prices were fair.

5.0 Mark S. Los Altos, CA

I am currently building an ADU (adjacent dwelling unit) on my property in North Los Altos. The project got off to a great start (at a reasonable price,) thanks to Mercoza concrete. The job involved preparing the concrete foundation (excavating the site, building the wood forms, rebar,) pouring the concrete, leveling and smoothing. Jason and Tranki had lots of valuable advice and knowledgable input. The crew was very efficient and pleasant to work with. We passed the first inspection with no problems. I strongly recommend Mercoza to anyone planning the construction of an ADU in the Bay Area. They are experts in concrete foundations, and they are dependable. Mark Starr

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.

HomeAdvisor verifies state-level licensing where applicable - note: 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.
