What adds to a Las Vegas quote
- The permit. Clark County and the valley cities require a permit for water heater replacement. A licensed plumber normally pulls it and includes it in the price.
- Code items. Seismic straps (upper and lower third of the tank) and a properly sized expansion tank are checked at inspection. If your old install lacks them, they get added.
- Tank to tankless. Gas line upsizing, new venting and electrical for the unit's controls.
- Location. A heater in a garage is easiest. One in an attic or interior closet costs more.
- Haul-away of the old heater. Most quotes include it; ask.
- After-hours calls. Nights and weekends often cost more.
Questions to ask before you say yes
- Is the permit included?
- Is the expansion tank included if it is needed?
- What is the gallon size and brand, and what is the warranty on the tank and on labor?
- Is haul-away included?
- What is your Nevada contractor license number? You can look it up with the Nevada State Contractors Board.
