Water heaters in Northern Virginia No hot water, or a puddle around the tank?

We answer day or night, and we will tell you honestly when we can get there. Common sizes are on the truck.

We do. SwiftPro’s own licensed plumbers repair and install tank and tankless water heaters, gas, propane or electric, across Loudoun County: Ashburn, Sterling, South Riding, Aldie and Leesburg. Fairfax, Prince William, Arlington and Fauquier counties too, from our shop in Chantilly. Call (703) 997-9757.

Us, day or night: (703) 997-9757. Close the cold shutoff on top of the heater, then the gas control to OFF or the breaker off. If the tank itself is leaking, it gets replaced: a rusted-through steel tank is not a repair. A dripping relief valve usually means no working expansion tank, and that is a repair. What a leak at the bottom usually means.

A gas tank here typically lasts eight to twelve years, electric a little longer, and a tankless up to 20 with a descale every year (Navien’s and Rinnai’s own figure). The serial tells you when it was built, though each maker codes it differently: an older Rheem starts with the month and year, an A.O. Smith with the year and week. How long each kind lasts.

Most houses should stay on a tank: same size, same corner, same fuel, done in an afternoon, for $2,400–$6,100 for 40 or 50 gallons installed. Tankless runs $7,500–$10,000+ because it is a conversion, not a swap: a bigger gas line, new venting and a yearly descale. It makes sense if you are remodeling, short on space, or done running out on the second shower. Tank ranges include all eligible discounts at the low end and the full financed price at the high end. Financing is available at 0% APR for 60 months on approved credit; the cash discount does not apply to financing. How financing works

Once a year. Sediment settles on the bottom and the burner fires through it: that is the popping. A tankless gets descaled once a year instead, and skipping it voids most warranties. A flush is $99 right now with a whole-home plumbing check, normally $199. Book the flush, or see every current offer.

Tank swap: two to four hours. Tankless conversion: most of a day, because the gas line and the venting are new work.

Yes. Replacement is permitted work in Northern Virginia. Skip it and it comes back at listing.

We publish prices for 40- and 50-gallon tanks, at the same price for either size. We confirm the right capacity for your household and hot-water use. For another size, contact us and we will help you find the right fit.

It holds if the room is what you said it was. A plumber measures and checks venting before the job is booked. Attic platforms, third-floor closets, and tight finished stairs are the usual extras.

Yes, every tier, subject to approval.

Send it. Second opinions are free. Sometimes the other company is right.

Yes. Repair, flush, anode, tankless descale. Any brand.

Call anyway. We answer day or night, and we will tell you honestly when we can get there. In a customer's words: “Our water heater failed at 8pm on a friday night, by 10am the next morning, Harold was at our house, removed the broken heater, and installed the new one.” (Conor D., Google review, September 2026)

No. You get the price for the heater that fits your house, in writing, before anyone starts. In a customer's words: “What stood out the most was that they never tried to sell me on anything I didn’t need.” (Desi M., Google review, January 2026)
