Water heater installation cost by job.
Installed-labor pricing for Redwood City, adjusted for local rates. Relocations and gas-line upgrades add to the base.
In Redwood City, where the median home was built in 1969, many older homes need water heater replacements. Typical installation costs for a standard tank heater range from $900 to $2,000, while tankless units run $2,000 to $5,000 or more. Local permits are required, and seismic strapping is mandatory under California law. Given the mild Mediterranean climate and moderate winter inlet water, a heat pump water heater is a strong fit, and the federal 25C tax credit (30%, up to $2,000) can offset costs.
