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.

Review by in 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.

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.

If you want to hire a contractor who is truly professional, prompt, knowledgeable, creative and fast ~ look no further than Doug Napoletano and D.E.N. Builders. Doug and crew arrived on time and within minutes were at work on my 2nd story deck repairing structural problems. Figuring it to be a 2-day job, I was astounded to learn they had repaired everything the first day including a few extra's that I hadn't expected, including moving a heavy metal cabinet I couldn't lift. Most importantly, their work was perfect (and I'm fussy!) and left the work area clean and rubbish-free. Doug knows what he's doing, moves quickly and has that "get it done" attitude. His prices are good and he delivers what he promises. I recommend DEN Builders and will definitely use them again. My search for a good contractor is finally over.

Doug showed up promptly to do the estimate, worked with us on timing, and delivered exactly what and when he promised, leaving everything cleaned up and fully functional. I will definitely seek to hire D.E.N. Builders for future contractor projects, if and as my budget permits.

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.

NOTE: Member service professional information confirmed as described above may change or expire over time; while HomeAdvisor attempts to maintain accurate and up-to-date information, and confirms changes when notified, we cannot guarantee that profile and screening information is accurate. Therefore, we recommend that before working with a service professional you verify that information presented is still current and/or acceptable to you.
