Is removal of my old water heater included in a replacement estimate?

Removal and haul-away of the existing unit is a common part of a replacement, but you should confirm it's listed in your written estimate rather than assume. Ask whether disposal is included so there's no surprise later.

What connections might a replacement estimate need to cover?

Gas, water, electrical, and venting or exhaust connections may need to change to match the new unit, especially if you're switching type or size. Confirm which connections the estimate includes and which, if any, are billed separately based on what's found on site.

What should I ask about that might not be included?

Ask about permits and inspections, expansion tanks or seismic strapping where required, code upgrades, and any access work. Understanding what's in scope and what could be extra helps you compare estimates honestly.

Water Heater Replacement Estimate Checklist

Two estimates that look similar can include very different scope. This checklist helps you ask the right questions before you commit.

Equipment and Model

Exact make, model, and capacity or flow rate listed
Fuel type matches your home (gas, electric, propane)
Tank vs. tankless clearly specified if you're switching
Whether the unit is the same type or a conversion

Removal and Disposal

Removing and disposing of the old unit is labor. Confirm whether haul-away and disposal are included in the estimate or billed separately. If you're switching from tank to tankless, removal may also involve disconnecting and capping old lines.

Connections and Code Items to Confirm

Category	Ask Whether It's Included
Water connections	New flex lines, valves, or pipe modifications
Gas supply	Gas line sizing or upgrades for the new unit
Electrical	Wiring or circuit changes for electric models
Venting / exhaust	New venting path for a different unit type
Safety items	Expansion tank, seismic strapping, drain pan
Permits & inspection	Permit filing and required inspection

Access and Exclusions

Access matters. If the unit is in a tight closet, an attic, or a garage with limited clearance, the work to reach it can affect the estimate. Confirm whether access-related labor is covered or could be extra based on what's found.

Finally, ask what the estimate does not include. A clear estimate names its exclusions so you can weigh the full picture rather than just the headline number.
