Frequently asked
Is $240 a fair price for water heater expansion tank installation in Indiana?
Yes. $240 is right around what most homeowners in Indiana pay. Anything from $27 to $539 is inside the normal range for a licensed plumber; above $539 it is worth getting a second quote.
Why do quotes for the same job vary so much?
Often cheapest when bundled with a water heater replacement. Pipe material and available space above the heater. 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 $539, 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.
