We do not publish prices, because they depend on the specific house, the heater chosen and the contractor. What we can do is explain what changes the scope of the job, so you can read a quote critically and compare like with like.
When two written quotes differ, line them up against the factors below. Often one includes updates or haul-away that the other leaves out.
Factors that change the scope
| Factor | Why it changes the job |
|---|---|
| Tank or tankless | Tankless often involves new venting, gas line and electrical work |
| Gas or electric | Fuel type affects parts, connections and any change of type |
| Size and model | Larger or higher-efficiency units differ in equipment and fit |
| Location and access | A tight hall closet or attic is harder than an open garage |
| Venting condition | An old or unsuitable vent may need replacing |
| Gas connection and shutoff | Rigid or old connectors and valves are commonly updated |
| Seismic strapping | New straps are part of a proper California installation |
| Pressure and expansion | Whether an expansion tank or regulator work is needed |
| Permit and inspection | City requirements and who handles them |
| Removal and disposal | Whether haul-away of the old heater is included |
Reading two quotes
A clear quote
- Names the heater make, model and size
- Lists venting, gas, strapping and water connection work
- States who handles the permit
- Includes or excludes haul-away explicitly
- Shows the contractor's CSLB license number
A vague quote
- Says only 'install water heater'
- Silent on code updates and permits
- Leaves disposal unstated
- No license number to check
Getting comparable quotes
- Describe the same job to everyone.Type, size, location and anything you already know needs updating.
- Ask for itemized scope.Not every line needs a price, but every piece of work should be listed.
- Check each license.Look up every contractor's CSLB license at cslb.ca.gov before choosing.
- Confirm the permit plan.Know who pulls it and whether inspection is included.
Common questions
- Why don't you list prices?
- Prices depend on the house, the heater and the contractor. Listing numbers here would be guesswork, so we focus on what changes the scope instead.
- Why is one quote so much higher than another?
- Usually because it includes more: venting, gas connector, straps, permit or haul-away. Compare the scope line by line.
- Is the cheapest quote a bad sign?
- Not necessarily, but check that it covers the same work, names the equipment and shows a valid CSLB license.
