Water heater installation cost by job.
Installed-labor pricing for San Carlos, adjusted for local rates. Relocations and gas-line upgrades add to the base.
In San Carlos, where the median home was built in 1961, water heater installation often involves updating outdated systems to meet current California codes. Local homeowners typically pay $800–$1,800 for a standard tank installation and $1,800–$4,600+ for tankless, with additional costs for new gas lines ($300–$1,000).
