Frequently asked
Is $490 a fair price for main water shutoff valve replacement in Connecticut?
Yes. $490 is right around what most homeowners in Connecticut pay. Anything from $105 to $770 is inside the normal range for a licensed plumber; above $770 it is worth getting a second quote.
Why do quotes for the same job vary so much?
Pipe material: copper, PEX, galvanized or CPVC change the fittings and the time. Whether the curb stop works or the utility must shut the water off at the street. 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 $770, 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.
