Water heater installation cost by job.
Installed-labor pricing for Longview, adjusted for local rates. Relocations and gas-line upgrades add to the base.
In Longview, Washington, the typical cost to install a standard tank water heater ranges from $700 to $1,550, while a tankless unit runs $1,550 to $3,900 or more. With a median home age of about 60 years and cold winter inlet water, many homes need updated systems. Local permits are required, and seismic strapping is mandatory.

Winter inlet water runs cold here, so recovery rate matters — size up a tankless or favor a high-recovery tank. A pro can confirm the right size and fuel for your home.
