Quick answers
- Age plus rusty water, rumbling, or lukewarm showers usually means repair vs replace — not another thermostat guess.
- Hard-water pockets across Arlington and Fairfax shorten tank life; annual flush and anode checks matter.
- Same-day replacements are common when the tank is leaking or you have no hot water in winter.
- We quote flat-rate before work — haul-away, expansion tank, and permit needs spelled out up front.
Who this is for
Use this guide when you are weighing water heater leaking from the bottom — what it means for an Arlington, Alexandria, or Fairfax County home and want local lifespans — not a national brochure.
What usually drives the decision in NoVA
Cold inlet temps, mineral scale, older galvanized or polybutylene-era supply lines, and tight mechanical closets in rowhouses change recovery, venting, and install cost. We check shutoffs, T&P discharge, combustion air or electrical capacity, and whether the symptom is the heater or a mixing/recirc issue.
What we verify on a service call
Age and model, leak source (tank vs fittings), burner/element health, anode condition when accessible, and code items for replacement. You get a clear repair vs replace recommendation in flat-rate terms — including what you do not need.
How NoVA housing stock changes the answer
Arlington rowhouses, Crystal City high-rises, and 1970s–90s Fairfax suburbs age differently. Local context beats a one-size national article.
What goes wrong
Replacing parts on a dying tank
New elements on a rusted tank buy days, not years — and can fail mid-week when you least want a flood.
Skipping expansion tanks or permits
Closed-system NoVA homes often need expansion protection; skipping it creates callbacks and code headaches.

FAQs
How long do tank water heaters last in Northern Virginia?
Typically 8–12 years here when hard water and sediment are in play. Past decade-old units with leaks, rust, or weak recovery are usually better replaced than patched.
Is no hot water an emergency?
In freezing weather or with small children/elderly in the home, treat it as urgent. Active tank leaks are emergencies — shut the cold supply and call (703) 214-2551.
Can I get a second opinion on a water heater quote?
Yes — send it through our free second-opinion form. We flag missing line items (expansion tank, haul-away, permit) without pressure.
