Why the choice matters more than the brand
People spend hours comparing water heater brands and minutes choosing who installs them. It should be the other way around. Most tanks from the major makers are broadly similar, and a good tank installed badly will leak, vent poorly or fail early. A decent tank installed well will do its job for a decade or more. The installer is the bigger variable.
Here's how to size one up, in the order that gets you the answer fastest.
Five questions to ask on the first call
You can learn a lot in a three-minute call. These are the questions worth asking, and what a good answer sounds like.
- "Are you a licensed plumber, and what's the license number?" A good answer is a number, given at once.
- "What's included in the price?" A good answer lists the unit, the labor, the permit, the code items and the removal of the old heater.
- "Who pulls the permit?" A good answer is that they do, and it's on the quote.
- "How long will it take, and who will be at the house?" A good answer is specific: a few hours for a like-for-like swap, longer for an attic or a conversion.
- "What if something turns up when you open it up?" A good answer is that they'll stop, tell you what they found, and give you the price in writing before going ahead.
How a company answers matters as much as what it says. A plumber who gives you a clear, unhurried answer to each is probably going to do the work the same way.
Check the license
In Texas, plumbing work for customers has to be done by a plumber licensed through the Texas State Board of Plumbing Examiners. A water heater installation counts. A handyman can't do it for pay, and a general contractor who isn't a licensed plumber can't either. The Board has an online lookup where you can check a name or a license number in a couple of minutes.
Ask for the license number. A plumber who hesitates to give it, or who talks around the question, has answered it.
Ask for the quote in writing, with the lines spelled out
A phone price is a starting point. Before anyone touches the old heater you should have a written quote that names the unit by size and fuel, and lists the labor, the permit where one is needed, the code items and the removal of the old heater, each on its own line. If there's a single number with nothing under it, ask what it includes.
The code items are where quotes differ most. A current installation has an expansion tank on a closed system, a drain pan where a leak could reach a ceiling, new connectors and a shut-off, and a relief valve piped to a safe spot. If one quote has all of them and another has none, they aren't the same job. The cost guide goes through what's in a typical number.
Ask about the permit
Where the city requires one, who pulls it? A good answer is "we do, and it's on the quote." A bad one is "you don't need one", or a lower price if you skip it. The permit is the thing that puts a second inspection on the work, and it's the homeowner who is on the hook if the job isn't signed off. The post on permits in Rowlett explains what's expected.
Ask who actually does the work
A quote from one person and an install by another is common enough, and not always a problem. But it's reasonable to ask who will be at the house, whether they're a licensed plumber or work under one, and how long the job will take. A like-for-like tank swap generally takes three to five hours. An attic install, a tankless conversion or a new gas line can take most of a day.
Ask whether the heater is tested at the tap before they leave. It should be filled, purged, powered or fired, checked for leaks and run hot at a faucet.
What a proper visit looks like
A good installer arrives on time, introduces themselves, and looks at the heater before anything else. They'll check the label, the vent or the circuit, the shut-off valve and the space around the heater, and they'll tell you what they see and whether it matches what you described on the phone.
They'll put protection down if they're working inside, shut the water off, drain the old tank to a hose, and disconnect it. They'll check what's behind it, because a heater that has sat for ten years often hides a surprise. The new unit goes in, gets piped and vented, and before they leave they should fill it, purge the air, test every joint for leaks, light it or power it, and run hot water at a tap.
Then they should show you the shut-off valve, the temperature setting and the relief valve, take the old heater away, and leave you the paperwork.
Ask what happens to the old heater
A tank is heavy, awkward and has to be drained. Some installers leave it for you to deal with, and some take it. It's a small question, and it tells you whether the quote is complete. The answer you want is that it's drained, disconnected and hauled away on the same visit.
Comparing two quotes side by side
When two quotes come in, line them up against the same list rather than comparing the totals. Does each name the size and the fuel? Is the permit in there, or not mentioned? Is there an expansion tank, a pan where the heater needs one, new connectors and a shut-off, and a relief pipe run to a safe place? Does the price include the removal of the old heater? Is there a statement of what happens if the unit turns out not to fit?
If one quote answers yes to all of those and the other is silent, the difference between them is rarely the difference in the total. Ask the quieter one to put it in writing. A good plumber will, with no complaint.
Watch for these
- A quote with no site visit and no questions about the heater, the vent or the circuit.
- A price that changes on the day, with the extra items appearing as you stand there.
- "No permit needed" or a discount for skipping it.
- No license number, or one that doesn't match the name on the Board's lookup.
- A request for the full payment before any work.
- A quote that lists no code items at all, in a house that clearly needs some.
- Pressure to decide on the spot.
A plumber who is confident in the work is happy to give you the time to read the paper.
What to keep afterward
When the job is done, ask for a copy of the receipt, the permit sign-off where there was one, and the details of the new heater: the model, the serial number and the warranty. Take a photo of the label and the finished install. Write the date somewhere you'll find it, such as the inside of a cupboard door beside the heater, so the age is never a guess.
These small records make the next job simpler, they help with a warranty claim if one is ever needed, and they're what a buyer or an inspector will ask for when you sell.
Payment and paperwork
How you pay says something too. For a standard swap, paying after the work is done and tested is normal. A modest deposit for a bigger job, where parts have to be ordered, can be reasonable, if it's written on the quote. A request for the whole price up front, in cash, with no paperwork, is the sort you walk away from.
Ask for an invoice that matches the quote, with the unit, the model and the serial number. If a permit was pulled, ask for a copy of the sign-off. These are normal requests, and a plumber who does the job properly has no trouble supplying them.
If something goes wrong in the first weeks, such as a leak at a connection or a heater that won't light, you want to be able to say what was installed and when. The paperwork is how you do that.
How we work, so you can compare
We take one kind of job, water heater installation, and nothing else, so every visit is about the heater. You tell us the age, size and fuel and where it sits, and you get an estimated range on the call. The written quote follows once the heater has been seen, with each line listed, and nothing is started before you've read it. Installs are done by a plumber licensed in Texas, the old heater is hauled away, and the new one is tested at the tap before we leave. Where Rowlett requires a permit, we handle it.
You can see what's included on the replacement page, and how quickly a swap can happen on the same-day page. If you're weighing a bigger change, the tankless page covers it. And whoever you choose, ask the questions above. They're fair, and a good installer expects them.
