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 Middleburg
Only about 4 in 100 owner homes in ZIP 20117 heat with utility gas. Six in ten use electricity and two in ten propane, and the water heater usually follows the house’s fuel. A propane tank heater is the same appliance as a natural gas one, set up for propane’s pressure, so it sits in the gas row of the price book.
Age is the other Middleburg story. About one home in four in the ZIP dates from 1939 or earlier, and the rented ones run oldest: the typical rental went up in 1952. In houses like those the water heater arrived decades later, often down a narrow cellar stair or into a back room corner, and the new tank has to leave the way the old one came in.
Inside the town limits, the Town asks any house with a softener or whole house filter for a check valve on the line feeding it. Where that valve sits on the main supply, the water a tank heats has no room to grow, and without an expansion tank the relief valve drips to let the pressure out. Every price here includes the expansion tank.
Storms here bring the power down with the trees: NOAA’s storm records list numerous trees blown down on Washington Street in June 2021, and hundreds of trees, branches and wires between Middleburg and Upperville in June 2022. An electric tank goes cold the moment the power drops. A standing pilot propane tank keeps going, because its thermocouple makes the small current its gas valve needs; a power vent or tankless heater has a fan and stops with the lights. Filling the propane tank is on the storm checklist in the Town’s own historic design guidelines.
By the numbers
From the Census Bureau’s 2020 to 2024 survey. Median year built and heat count owner-occupied homes only.
ZIP 20117 as a whole: every Middleburg address, the Town and the farms around it, about a tenth of the land in Fauquier County. The Census place for the Town alone has too few homes for steady figures.
What you’d notice
On an electric tank, the high-limit switch can trip when power drops and returns in a storm, leaving the water cold with the breaker on. It sits behind the upper panel beside live wiring and trips for a reason, so have it checked before anyone resets it.
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
Loudoun County requires a permit to swap a gas water heater or furnace. Since October 2025, a replacement that keeps the same BTUs in the same spot needs no plans. 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 Loudoun County by the end of the next working day. Source.
Our Virginia Class A contractor license, 2705192276, is on the side of the van.
Choosing who installs it
Questions worth asking anybody who quotes you, us included.
Trading a tank for a power vent or tankless heater means a new exhaust pipe through a wall. In the Historic District, one the street can see needs a Certificate of Appropriateness before it goes in, so a good quote picks the wall with that in mind.
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.

Questions
The pipes at it can, in a cellar or utility room that isn’t heated; a weather station in Middleburg read 4 below zero on January 23, 2025. If the lines at the heater freeze, switch an electric tank’s breaker off or set the propane valve to pilot, and call us before anybody puts a flame near the pipes.
It can reach low ground. On September 30, 2015 the Goose Creek gauge at Middleburg passed its 13 foot flood stage and topped out near 14.5 feet, and Notre Dame Lane began to flood at the creek.
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.
