Installed, from our water heater estimator, which is the price book. Everything is in the number: the permit and the inspection, the expansion tank, the drain pan, hauling the old one away, and the labor.

How the house vents picks the row; where you land inside it is the tank size and the warranty. A hybrid heat pump water heater is quoted at the visit, never from a page.
Keeping the one you have? A yearly water heater flush slows the sediment down: $99 right now, normally $199. A tankless descale is $300, regularly $350. Or get the flush every year with Comfort+ membership, $199 a year, along with a dryer vent cleaning, a sewer camera inspection and heating and cooling maintenance visits.
What’s different in Calverton
Calverton’s own ZIP, 20138, is post office boxes, so the Census numbers here are for Catlett’s 20119, where most Calverton houses get their mail. The Census counts no owner home there on utility gas: about half use electricity and close to three in ten propane, and the water heater usually matches the heat. An electric tank prices on our electric row, a propane tank on the gas row.
On August 29, 2024, a thunderstorm with gusts estimated near 64 mph blew down numerous trees near Calverton. When the lines go with them, a well’s pump stops along with any electric tank, so the taps slow to nothing once the pressure tank empties. A propane tank with a standing pilot keeps its water hot through it; a power-vent or tankless propane heater stops with its fan.
The Warrenton 3 SE co-op station, six miles west-northwest, counts 98 nights a year when the low reaches 32 or colder, and it bottomed out at 2 degrees on February 20 and 21, 2015. A heater in a crawl space or an unheated garage is where nights like those do damage, usually to the cold line or the drain valve, and a split pipe beside the tank pours water like the tank itself gave out.
The County’s plan says an extensive floodplain runs through the middle of the village, and Bastable Mill Road has closed for high water four times since 2014, at Turkey Run and near Brookfield Drive. If water reached the wellhead as well as the heater, Virginia Tech’s well guidance calls for shock chlorinating after any flooding and suggests draining the water heater to help clear it. The well is a well contractor’s; the tank is ours.
By the numbers
From the Census Bureau’s 2020 to 2024 survey. Median year built and heat count owner-occupied homes only.
Calverton’s own ZIP, 20138, is post office boxes only, so the Census Bureau maps no area for it. These are ZIP 20119 as a whole, the Catlett ZIP area that holds nearly nine in ten of the Calverton Census place’s homes.
What you’d notice
Virginia Tech’s well clinics found a pH under 6.5 in 46 percent of Fauquier County samples, and acidic water eats copper fittings and a tank’s anode rod early. Crusted connections on top of the heater mean both deserve a look before a younger tank gets written off.
An electric tank has two elements. When one fails the water still warms, just never all the way; it’s a common, fixable part.
A drip from a valve can be fixed. Water from the tank itself can’t; once the lining goes, the only fix is a new heater, and sooner beats later.
If the basement took water
A water heater usually sits on the lowest floor of the house, so it’s one of the first things standing water reaches. Three checks, then call us.
Leave it off and don’t relight it. The warning label on a gas water heater says not to use it if any part has been under water, and to have a service technician replace the gas control.
Shut its breaker off at the panel, but only from somewhere dry. The elements and the thermostats get checked before it heats again.
Mop it up and look again in an hour. Water that comes back with no rain is the tank or a valve, not the storm.
Call us after a storm and we’ll check it: the gas control or the elements, the burner, the venting and the drain pan. If it has to be replaced, you get the price in writing before anything comes out.
Permits and pressure
Outside the town limits, Fauquier County issues the permit. It wants one for any fuel-fired water heater, propane included, and for any heater being moved; an electric one swapped for a similar unit in the same spot counts as an ordinary repair. Trade permits go out over the counter the day the application comes in. Source.
A burst tank doesn’t wait on paperwork: under Virginia’s building code the replacement can start first, as long as the permit application reaches Fauquier County’s Building office by the end of the next working day. Source.

Choosing who installs it
Questions worth asking anybody who quotes you, us included.
A Calverton well often has a sediment filter, softener or acid neutralizer ahead of the tank. Ask the installer to keep its bypass valves reachable once the new heater is in.
A gas water heater always needs a permit, an electric one often does, and skipping it tends to surface when the house sells. Ask whether the quote includes it and the inspection.
Most houses here have a check valve or a pressure reducer on the incoming line, so the heated water has nowhere to go. An expansion tank gives it somewhere, and leaving it out is how quotes come in low.
A thermocouple, an element or a valve is a repair, not a new heater. A good plumber says so, and saves the replacement talk for a leaking tank.

Jim was very professional, knowledgeable and polite plumber. He installed a water heater for us. After the installation he educated us on the maintenance and the new set up. I strongly recommend Jim/SwiftPro. Plus SwiftPro price was very reasonable/20% below other estimates.
Questions
Keep an electric tank’s breaker off until the tank refills: open a hot tap, wait until it runs steady with no sputtering air, then turn the breaker on. An element that heats with no water around it burns out quickly. A propane tank gets the same refill before its burner lights.
A tankless propane heater needs power for its fan and controls, so it goes dark in an outage, and well water carrying iron or manganese needs a filter ahead of it and a regular descale, $300 right now. Where storms take the power, a standing-pilot propane tank is the plainer choice.
Installed, with the permit, the expansion tank, the pan and the haul-away: an electric tank $2,757 to $5,493, a gas or propane tank on the flue you have $3,379 to $5,485, a power vent tank $5,957 to $7,494, and a tankless unit $8,886 to $10,486. The estimator gives your exact number in about a minute.
