Project Overview
✔ Location: Pasadena, CA
✔ Contractor: Altadena Handyman LLC
✔ License: CA Plumbing Contractor #1025813
The home had aging galvanized supply lines that were restricting water flow and impacting water quality. A full house re-pipe was recommended to improve system reliability and long-term performance.
As part of the upgrade, the homeowner also chose to replace the existing tank-style water heater with a modern tankless system, providing improved efficiency and consistent on-demand hot water.
All plumbing work was completed under one license, with drywall access and restoration handled as needed to leave the home clean and fully finished.
