    5.0 Maggie S. Columbia, MD

    Mr. Keller called me promptly after submitting my request on Home Advisor and came out the same day. Very professional and caring about the needs of the client. Felt very comfortable about the pricing information he gave me. I had two sinks installed and a year later, a faucet repair. The employees who did the job were courteous, timely, and did a great job. I would highly recommend them. They were pretty good at estimating the time of arrival and actually arriving on time, if not a little early.

    0.0 Max P. Ellicott City, MD

    Was called within seconds of submitting request and plumber was at my house 15 minutes later. A little pricey but unfortunately that's what plumbers cost. Did some additional work (caulking around bathtub) and included it in quote. Professional and very helpful. Would definitely recommend Heller.

    Keller Plumbing and Heating did great job.

    0.0 Leslie A. Columbia, MD

    They arrived on time and we had hot water a few hours later. I could not have been happier.

    0.0 John S. Columbia, MD

    They were late in coming, but did the job quickly and for less than their estimate.

    0.0 Tishna D. Columbia, MD

    Fairly priced. The two workers cleaned up all dust and debris from the job site. Most contractors leave a mess. These guys cleaned up everything. I would use them again. They showed up on time as well. Thank you!

    Keller came the day after I called, did all the work to my satisfaction and I have hired them to replace my laundry tubs later this month,

    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.
