Frequently Asked Questions

- How do I find a reliable plumbing & irrigation contractor in Seattle?
- Licensed plumbers carry insurance that covers water damage from their work — this matters. Ask about warranty on labor, not just parts. For water heater installs, check whether the quote includes removal of the old unit.
