Worker is very courteous, he tells you exactly what he is going to do. Job was performed in a timely manner, follow up work is good. Price is right.

Review by in San Jose, CA
I had a gas leak under the ground and the gas provider shut off gas line because of general inspection. Home Advisor provided me two companies to call for estimates for my project. Giant Plumbing responded very quickly and came to my home to give me the estimate. The project has been delayed for three days because of my decision. Finally I decide to go through Home Advisor and the turn out was great. Next time I will recommend the company Giant Plumbing, although the price is a little on the high side.
Response by Giant Plumbing, Inc.: We appreciate your business. Thank you! We did provide you with an estimate and you did get other estimates and I believe we were the cheapest and did a great job. We had 2 plumbers on site for 3.5 hours a total of 7 man hours and charged only $700.00 parts and labor to repair 3 gas leaks.

Very satisfied with their work and Don was responsive during the process. His plumber kept me informed during each stage of the project. I would rehire them for future work.

Don was very responsive and cost competitive with other bids I got. Went with Giant partly because they were able to get on the job the earliest and I was very satisfied with their work and they were done in the time they estimated. I will hire them again when required.

The owner Don and his team were very professional and courteous. The scope of the job grew but am happy with the outcome and fair price. I'm confident if there happens to be any future problem, Don would stand by his work. Yes, would definitely use again and recommend to others.

They did a great job. They gave a bid for the work which was reasonable. They arrived on time, replaced the two leaking waterlines and cleaned up after they were finished. I would use them again.

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.
