What is the after-hours rate?

Emergency rates vary widely. Ask before the plumber is dispatched.

How soon can they arrive?

Ask for an arrival window, not just a promise of 24/7 service.

Is the gas setup right for altitude?

Gas water heaters in Denver need altitude-appropriate venting and burner settings. Ask the plumber to confirm the install meets local code and manufacturer altitude guidance.
