Pricing
What is the price range for water heater replacement in Fairfax?
From $2,000 for a same-size, same-fuel tank.
Do I need a permit to replace a water heater in Fairfax County?
Yes. Fairfax County Land Development Services says gas appliances are not exempt, so even a like-for-like gas water heater needs a permit. A direct replacement with no new gas piping uses a Household Appliance permit with one inspection; adding gas piping moves it to a Residential Plumbing permit. Fuel-burning replacements also need a chimney vent certification. Homes in the towns of Clifton or Vienna need separate town approval.
Pricing
Are permit fees part of the cost in Fairfax County?
Ask any installer whether the permit is in the quote; an installer who offers to skip it is a red flag.
Pricing
What changes the price?
- Gas versus electric, and whether venting meets current code
- Tank size and household demand
- New gas piping, which changes the permit type
- Location: closet, attic, basement or garage
- Expansion tank or relief-valve piping updates
Is it cheaper to repair or replace?
A failed part on a sound tank is worth repairing. A leaking tank is not.
