Expensive but thorough. There was a minor scheduling issue that was quickly resolved, and the job was completed VERY quickly.

A troublesome shower drain was resolved quickly by Oak Plumbing. I want to recognize Niles, Harris, Jessy, and Amari for their great work. Niles inspected the crawlspace, measured every line, and gave me a fair quote based on my home’s actual layout. Harris cleared space for the new pipes, sketched the floor plan, and confirmed materials. Jessy and Amari replaced all horizontal drain lines—including the garage sink, washer, kitchen sink, two toilets, shower, and two sinks—in tough conditions under the house. This started after another company gave me a flat-fee quote based on “two bathrooms.” Oak Plumbing’s quote was more detailed and more accurate for my 1950s home with 1.5 baths and mixed old materials. Their bid was over 10% better, and I left a deposit that day. I’m grateful for how quickly they solved the problem, especially days before Thanksgiving. As a single mother who relies on Angie’s List, this experience fully met expectations. I highly recommend Oak Plumbing.

Spent too much time discussing a replacement faucet. Did schedule very quickly which was appreciated, did do the work requested quickly after “discussion “ stopped. I do feel that the “come on” $49 work estimate fee gets you involved with them when you have no idea that the cost would be so much! This I find is the norm with plumbers on Angi. Total cost for a simple procedure( yes I could not do myself) was at least 50% more than I thought.

Koda and Billy were great problem solvers that saved me a lot of money. The company is not the least expensive, but they are excellent with integrity and honesty

Malik was very punctual, polite and went into detail about the work, what it will require and estimate time on how long the job will take. I am happy with the work and for sure hired Oak Plumbing for any future work, highly recommended them.

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.
