    5.0 Kevin T. San Lorenzo, CA

    Amazing job. Dan and his team were very professional and very easy to work with. Pricing was very fair and the quality of work was well worth it. We will definitely be calling them back for any concrete needs.

    4.0 Ed A. Dublin, CA

    Dan did a great job communicating with me and getting the work planned, performed and knocked out!

    5.0 James B. Alamo, CA

    Dan and team did a great job. I appreciated his knowledge and insight along the way as there were engineering changes that happened mid course. Dan provided his professional opinion along with GC in working with Architect/Engineers. They got it done and we are completed satisfied.

    5.0 Hayward, CA

    Concrete looks great! These guys did an awesome job! They did a good job cleaning up. They were also very accommodating in letting me take photos at various stages. This was a 20 by 10 slab for an outdoor shed. Work was completed in two days. Dan is very accessible for questions and easy to talk to. Highly recommended!

    5.0 Keith C. Walnut Creek, CA

    This crew was very neat and kept the site clean. The owner was available each day to ensure the quality of the work.

    5.0 Paul B. Oakland, CA

    Dan knows concrete and how to do quality worked based on knowing his trade. He manages a hardworking and dedicated to their trade crew. They all work hard and kept the job site clean. They did an excellent job and finished on time as expected. His bid was very fair. In the bidding process he stood out from other bidders. My car pad job in the Oakland Hills had unique drainage and sloping issues. These guys were awesome. It is such a pleasure when it now rains or to get in and out of my car to admire the work. During construction neighbors actually drove by and gave his crew a thumbs up. It is not often you see that kind of contractor neighbor bliss. Thanks again Dan and crew.

    N/A Ann A. Castro Valley, CA

    we were very satisfied with his complete job, very professional.

    N/A Michael M. Oakland, CA

    Dan Long is professional, cordial, and experienced. He considered not only routine matters of removal and installation, but also related issues of drainage, design, maintenance, and budget. He listened carefully, gave me choices, and responded clearly to my questions. The job itself began on schedule, proceeded without delays, and was conducted by an experienced, agreeable crew who were attentive to detail at every point. The result is a patio more beautiful than I imagined, at a price less than I anticipated.

    N/A Michael C. Oakland, CA

    excellent work highly recommend.

    N/A Duane S. Oakland, CA

    Dan Long and company are about as good as they get. The design and implementation of a cement floor in the basement turned out better than expected. He was innovative in his design and added value to my requirements. Except for the few days his email got hacked (which can happen) he provided continual updates as to what he was doing and going to do next re the project. Strongly recommended for your concrete/cement needs.

    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)
