Review by in Moraga, CA
The job was completed, but not before a brief flood due to the soldering not holding. Fortunately no permanent damage, but it was not a good experience.

Harry had the most reasonable quote to take out the tub and install a shower pan for a walk in shower. He did the tear out one day and installed the pan the next day. A day later he stopped by to inspect the job. He found something he didn't like and replaced the shower pan with a new one at no additional cost. A true craftsman and a gentleman to boot.

I had 5 different plumbing contractors look at my needed repair. They all had basically the same solution and high costs. Harry looked at the problem (repairing and installing 80ft of copper plumbing from the main to my house) and came up with a completely new and better solution at a lower cost. Harry was diligent and responsive and truly cared about a quality outcome and a sound repair. I would highly recommend Harry for all your plumbing needs.

Review by in San Ramon, CA
I am very happy with Harry and his work. We wanted route a gas line, hot and cold water, and a drain to our backyard for an outdoor kitchen. Harry was punctual, did the work to estimate, and the quality of his work is second to no one. He was meticulous to the quality of his work and made sure everything was thoroughly tested before he left. His prices are very reasonable as well (compared with online estimates for linear foot of extending plumbing, his price was better than a general contractor’s that did a bid for the job). Not only did Harry do a great job for our project, I asked him to look at a leaking water heater and he fixed it in minutes. I ultimately will need to replace my tankless water heater and will call Harry when I do. I would recommend Harry to all my friends and family. Harry came highly rated on Home Advisor and he did not disappoint.

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)
