Frequently asked
Is $2,450 a fair price for electric water heater replacement (40–50 gallon tank) in Illinois?
Yes. $2,450 is right around what most homeowners in Illinois pay. Anything from $396 to $5,060 is inside the normal range for a licensed plumber; above $5,060 it is worth getting a second quote.
Why do quotes for the same job vary so much?
Heat-pump (hybrid) water heaters cost roughly double a standard electric tank, though rebates can offset that. Code upgrades required at replacement: expansion tank, pan with drain, disconnect switch. Company overhead matters too: a large company with trucks, dispatchers and a warranty department charges more than a one-person shop, and both can be honest prices.
When should I get a second quote?
Any time a quote lands above $5,060, or when the contractor cannot break it into parts, labor and fees. Ask for the itemized version, ask what would change the price, and confirm licensing and insurance. You can also paste the quote into the free QuoteJury checker for an instant second opinion.
