What should I do with this quote this week?
Compare the quote against the local range of about $1,300 to $2,450 for a standard 40-gallon tank. Ask whether the price includes the plumbing permit, which is about $62 in Kansas City. Confirm the scope covers the T&P valve, discharge pipe, drain pan where required, and expansion tank if the home has a closed system.
When does a $1,400 quote become too high?
Prices rise when the job includes switching fuel types, moving the unit, or correcting old plumbing to code. HomeGuide says these changes can add $75 to $500. A tankless conversion is a different job and typically runs about $3,000 to $6,000 or more.
What should I verify before hiring the plumber?
Kansas City requires a licensed plumber for water heater replacement unless you are working on your own owner-occupied home. Ask the pro for proof of licence and insurance. Check the quote for the permit and the code items listed above.
What to do next
- Ask the quote to list the permit fee, which is about $62 in Kansas City, as a separate line.
- Confirm the quote includes the T&P valve, discharge pipe, drain pan where required, and expansion tank if needed.
- Ask the pro for proof of plumber licence and insurance before work starts.
- Get the scope in writing, noting whether the job is a same-for-same tank swap or includes fuel or code changes.
