5.0 Ryan M. Granite Bay, CA

Hands down the best Hot water company I have ever dealt with. If you are you looking for an honest professional to service your home, look no further. You will not be disappointed. Getting estimates has always been a hassle for me until I found this company. Thank you!

5.0 David D. Lincoln, CA

FIVE STAR all the way around!! Very nice and honest people. Quick response and installed new water heater in a timely manner (next day). Excellent job. Highly recommend.

5.0 Frank G. Roseville, CA

Doug responded quickly to my repair request. They were able to schedule my repair for that same day. They arrived on time (maybe even a little early) and quickly made the repair.

5.0 Pedro D. Sacramento, CA

So far so good.

5.0 Ken K. Roseville, CA

Doug was very personable and answered all my questions. Felt very comfortable with the work done, final price and product purchased. Would highly recommend The Hot Water Heater Company to anyone looking to have a hot water heater installed!

5.0 Dawn B. Rocklin, CA

AMAZING SERVICE! Doug and Dave were so easy to work with and very professional. The work they do is top-notch. I would hire them again. Thank you so much!

5.0 Steve Q. Rocklin, CA

Very responsive. Called one day and got a quote and tankless water heater was installed the next day. A miracle especially during Covid with all the other home improvement delays we are experiencing. Doug is very knowledgeable even if I had to ask him to dummy it down for me a couple of times. Price was competitive and service was outstanding.

5.0 Ron N. Rocklin, CA

Doug got back to me on a weekend when other firms I called did not. He was very honest and worked with me through numerous text messages to diagnose the issue. We had agreed on a reasonable price to fix the unit when Doug texted me back asking me to watch a you tube video to see if I could reset the unit myself. He said it was worth taking a chance so I did and it worked! Problem fixed. I offered Doug $100 for his time and expertise, but he said no thanks. He was glad to help. While I did not have any work done I give Doug and the Hot Water Heater Company 5 stars for honesty, expertise and willingness to spend their valuable time helping me get our hot water back. If my unit eventually breaks I will be calling them to do the repair.

5.0 Gregory K. Roseville, CA

Doug responded quickly on a Sunday night and was here to do the job the next day. He rerouted the pipes and changed the angle of the pressure tank for a cleaner installation at no extra charge. Thanks Doug

5.0 Jennifer S. Roseville, CA

Fast, communicative, knowledgeable, and responsive! Absolute pleasure working with them. Wish all service businesses operating at such a high level with such high professional and ethical standards!

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.
