Water heater installation cost by job.
Installed-labor pricing for Biddeford, adjusted for local rates. Relocations and gas-line upgrades add to the base.
In Biddeford, Maine, water heater installation costs typically range from $650 to $1,500 for a standard tank unit and $1,500 to $3,700+ for a tankless system. With many homes built around 1954, older plumbing and tight spaces can increase labor time.
