    5.0 Dan S. Walnut Creek, CA

    Doug did a great job of presenting his services and gave us the confidence that he could do the job right. Gave us a bid that met our budget and was on site through the process to ensure it was done correctly. His crew was great and the finished product turned out wonderfully. We are very happy with the service and we would recommend D.E.N. to others!

    5.0 Brian U. Walnut Creek, CA

    Doug and his team did a great job. They showed up on time each day (3 day redwood deck project) and did a real quality job. The best materials and careful attention to detail. The finished product was even better than promised. I could not be happier & I would recommend DEN Builders to all.

    5.0 Dede/richard H. Oakley, CA

    The owner Doug was very easy to work with. He listened to us during his first visit. He and his crew was very respectful of our property and cleaned up after the work was done. We're enjoying the new deck DEN built us and I'm sure it's added a lot of value to our home's worth. We look forward to working with Doug and his company on some other home improvement ideas we have.

    5.0 Kat K. Walnut Creek, CA

    It was wonderful. I feel that like they went above and beyond. It was a professional group of workers. The head contractor named Doug was always on time which I thought fabulous. I will be contacting them again to complete a bathroom remodel.

    5.0 Frances S. Rodeo, CA

    D.E.N. Builders were great. The service they provided was excellent. They were professional, prompt knowledgeable and helpful. Doug is a very personable person and I would use his services again without a second thought. They did a great job!

    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.
