Mr Rooter Plumbing
Jose was very professional and all contact with Mr Rooter was handled very well from office staff Nicki on down.
We had a blocked toilet that was just recently added to our home. The technician discovered that our main line out to the sewer had blockage, corrected the problem and we have a free flow ever since.
Very responsive and communicative, a relief when I wasn't able to be at the service site in person. The technician supplied us with detailed info and emailed videos regarding the pipe. Thank you!

Review Analysis
Customer reviews are aggregated from Google and analyzed to identify patterns in service quality.
Detailed Comparison
We analyze credentials, insurance, experience, and feedback to highlight meaningful differences.
Not all licensed contractors are created equal. While a valid license is the baseline requirement in California, contractors can vary significantly in experience, insurance coverage, and customer satisfaction.
- Experience matters: A contractor with 15+ years of experience has likely encountered and solved problems that newer contractors haven't faced yet.
- Workers' compensation protects you: If a contractor without workers' comp insurance has an employee injured on your property, you could be held liable.
- Reviews reveal patterns: Individual reviews can be misleading, but patterns across many reviews often reveal a contractor's true strengths and weaknesses.
- Bond amounts vary: A contractor's bond provides financial protection if they fail to complete work as agreed. Higher bonds offer more protection.
Taking time to compare contractors on these factors can save you from costly mistakes and help ensure your project is completed by a qualified professional.
