Frequently asked
Is $460 a fair price for water pressure regulator (PRV) replacement in Delaware?
Yes. $460 is right around what most homeowners in Delaware pay. Anything from $120 to $781 is inside the normal range for a licensed plumber; above $781 it is worth getting a second quote.
Why do quotes for the same job vary so much?
Valve size (3/4-inch versus 1-inch) and brand. Location: an accessible basement or garage valve versus one buried at the meter or in a crawlspace. 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 $781, 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.
