Frequently Asked Questions
For a straightforward drain clearing, probably not—both companies have decades of experience with routine clogs. The experience gap becomes meaningful if your drain issue reveals underlying sewer line damage, root intrusion, or system problems requiring diagnosis and repair recommendations. Water Quality's extra 12 years means more exposure to complicated scenarios in older homes.
While their name emphasizes drain and sewer work, $15 Sewer does perform fixture installations and general plumbing repairs according to their description. However, customer reviews predominantly mention drain-related work, whereas Water Quality's feedback specifically highlights successful water heater replacements and complex installations, suggesting deeper experience with those project types.
Water Quality's 51 years of operation means they've been working on Bay Area homes since the early 1970s, providing extensive exposure to the plumbing systems, materials, and common failure points in older local housing stock. This historical perspective becomes valuable when diagnosing problems in homes with outdated galvanized pipes, polybutylene, or original copper that may need replacement soon.
For drain emergencies specifically, yes—customer reviews consistently emphasize their one-to-two-hour response times. However, Water Quality also receives positive feedback for responsiveness and quick scheduling. If your emergency involves something other than a drain clog, Water Quality's broader technical capability may be more important than a slightly faster arrival time.

How We Compare Contractors
License Verification
All license data is sourced from official California CSLB records and verified regularly.
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.
