The honest answer

Should You Repair or Replace?

The answer depends on age, condition, and repair cost — not a sales script. Here's the honest framework we use when we assess your unit.

Repair makes sense when…
Repair the Unit
Often the right call for a younger, well-maintained water heater
  • Unit is under 8 years old
  • Repair cost is less than 50% of replacement cost
  • No visible rust on the tank itself (element, valve, or thermostat issue)
  • Pilot light or igniter failure — a straightforward repair
  • Sediment buildup causing noise — resolved with a flush
  • Pressure relief valve failure only
Replace when…
Replace the Unit
Usually the smarter investment for older or failing tanks
  • Unit is 10–12+ years old (average lifespan for tank heaters)
  • Repair cost is 50% or more of a new unit installed
  • Rust-colored water coming from hot taps — tank is corroding internally
  • Active leak from the tank body — cannot be repaired
  • Multiple failures in a short period — the unit is declining
  • Energy bills rising — older heaters become inefficient

FAQ

Water Heater Questions DC & Maryland Homeowners Ask

How do I know if my water heater needs repair or full replacement?
If your unit is under 8 years old and the repair is under 50% of replacement cost, repair usually makes sense. If it's 10+ years old or has rust-colored water or tank leaks, replacement is almost always the better investment. We'll tell you honestly after seeing the unit.
What does water heater replacement cost in Washington DC?
Tank replacement in the DC/MD area typically runs $900–$2,000 installed. Tankless systems are $2,500–$4,500 or more depending on gas line and venting requirements. We provide a written quote before any work starts — no surprises.
How long does a water heater replacement take?
A standard tank swap typically takes 2–3 hours. Tankless installations require 4–6 hours, especially if venting or gas line upgrades are needed. We give you a realistic time estimate when we schedule.
Do you install tankless water heaters in DC and Maryland?
Yes — we install Navien, Rinnai, Noritz, Rheem, and other major tankless brands in both DC and Maryland. We handle all required permits and gas line work as part of the installation.
Is tankless worth the higher upfront cost?
For many DC and Maryland homeowners — especially in larger homes or households with high hot water demand — yes. Tankless units are 24–34% more energy efficient, last 20+ years vs 10–12 for tanks, and never run out of hot water. Whether it makes sense for your situation depends on your home's gas line capacity and venting setup, which we assess during the visit.
Do you offer financing for water heater replacement?
Yes — financing options are available for qualifying water heater replacement jobs. Ask about 0% financing on approved credit when you request your quote. Available for both tank and tankless replacements.
