Installed-labor pricing for Crest Hill, adjusted for local rates. Relocations and gas-line upgrades add to the base.
In Crest Hill, where the median home was built in 1991, many water heaters are reaching the end of their 10-15 year lifespan. Typical installed costs for a standard gas tank water heater range from $700 to $1,500, while tankless installations run $1,500 to $3,800 or more, plus $250 to $850 for a new gas line if needed.
