What labor covers
The labor line on a replacement quote covers draining the old tank, disconnecting gas or power and water, removing the unit, setting the new heater, making all connections, filling and testing, and hauling the old tank away. It also covers the time spent getting the permit and meeting the inspector.
A quote that lists only a single labor amount hides what is included. A good one lists the items, so you can compare. Our water heater replacement page explains the process from call to hot water.
Where labor time goes
Read the labor line against this table. A short quote that skips code items may mean you are paying for them later.
| Task | What it involves | Can add time when |
|---|---|---|
| Drain and removal | Empty the tank and carry out the old unit. | Tight stairs, a finished basement or a heavy tank. |
| Connections | New water connectors, shutoff and gas or electric hookup. | Old corroded fittings or unions. |
| Venting | Connect the flue or power vent. | Existing vent is damaged or the wrong size. |
| Code items | Relief valve, discharge pipe, pan, expansion tank. | Missing from the old install. |
| Test and start | Fill, purge air, leak test and combustion check. | Gas leak or draft problems found. |
| Permit and inspection | Paperwork and a final inspection. | Inspector needs a correction. |
Why the cheapest labor is not always cheaper
A quote that leaves out a new relief valve, a discharge pipe or a shutoff valve will not pass inspection in many places. An installer who skips the permit leaves you exposed, because an unpermitted water heater can cause problems when you sell or file an insurance claim.
Ask each contractor what is included, and ask who pulls the permit. We give a clear price before work starts, and we list the items so you can see what you are paying for.

What the Vernon Hills guide adds to labor
The Village of Vernon Hills publishes a permit guide for water heater replacement. It describes an over-the-counter permit, a final inspection and a completion bond, plus a new temperature and pressure relief valve, metallic discharge piping, a shutoff on the cold line and a gas shutoff or electric disconnect. Those items are labor and parts that belong on the quote.
Inspections are on weekdays and requested ahead of time, so an emergency swap on a weekend may be inspected later. Confirm the current rules with the building department at 847-367-3700. Plumbers are licensed through IDPH, which offers a plumbing license verification lookup.

A failed heater at night is an emergency for many families. After-hours work costs more because the crew is called out of schedule. We state the after-hours price before work starts, so there are no surprises.
If the leak is not urgent, a next-day appointment is usually cheaper, and same-day slots are offered when available. Shut the water and the gas or power off at the heater, drain what you can and keep the area dry in the meantime.
What a good quote and a good visit look like
A good quote is written, itemized and dated. It names the model, the fuel type, the size and the warranty, and it lists the code items. It says who pulls the permit, what happens to the old tank and what the after-hours rate is, if any.
On the day, the crew should protect floors, shut off utilities, test for leaks and combustion, and explain how to operate the new unit. They should leave you with the paperwork, the warranty details and the inspection date.
Take a photo of the finished install, including the discharge pipe and the shutoffs. It helps if you ever have a question later.
Questions to ask before you hire
Ask whether the quote includes the permit, the haul-away, the relief valve and discharge pipe, the expansion tank if needed and a warranty on labor. Ask how long the job will take and who will be on site.
If your project involves a change from gas to electric, a move to tankless or work in a tight space, the labor changes. See our tankless water heater page for how that affects the job. Homes in Mundelein and nearby towns follow similar steps, with local permit rules.
Rules and guidance note
The village permit guide describes an over-the-counter permit and a final inspection for a tank replacement, and a permit fee is a separate cost from labor. Confirm the current amount with the Village of Vernon Hills building department at 847-367-3700.
Our guide does not quote unverified prices.
