What to Look for in a Water Heater Replacement Pro

Signs Your Water Heater Needs Replacing
Not every water heater problem means replacement. But some signs make it clear that your unit has reached the end of its useful life and continuing to repair it is throwing money away. Here are the four clearest indicators.
When replacement is the right call, we provide an upfront written quote covering everything: unit, labor, disposal, all code updates, and cleanup. No hidden charges, no surprise add ons.
Tank Is Leaking
Water pooling under the unit from the tank body (not fittings) means internal corrosion. The tank cannot be repaired and will eventually rupture and flood.
Replace Now →Unit Over 12 Years Old
Most tank water heaters last 8 to 12 years. After that, efficiency drops, parts become harder to source, and the risk of catastrophic failure increases every year.
Get a Quote →Rusty or Discolored Water
Rusty hot water coming from multiple faucets means the tank interior is corroding. Once the lining fails, the tank will eventually leak and needs replacing.
Diagnose →Constant Repairs
If you've repaired the same unit two or three times in the past year, the cost of continued repairs exceeds the value of the aging unit. Replacement saves money long term.

Why Professional Replacement Matters
A water heater replacement involves draining and removing a heavy tank, disconnecting gas or high voltage electrical, handling exhaust venting, positioning a new unit, reconnecting everything to current code, and testing the entire system. Improper replacement causes gas leaks, carbon monoxide exposure, flooding, electrical fires, and failed inspections.
Licensed plumbers ensure every gas connection is pressure tested, every vent drafts properly, every expansion tank is sized and installed to code, every electrical connection is safe, and every unit is strapped, panned, and permitted, protecting your home and your family.

Water Heater Replacement FAQs
Common replacement questions answered by our licensed plumbing experts serving Whatcom and Skagit Counties.
How much does a water heater replacement cost?
A standard 50 gallon gas or electric tank replacement typically runs $1,200 to $2,500 including the unit, labor, old tank disposal, and all code updates. Tankless conversions range from $3,000 to $5,500. We always provide an upfront written quote.
How long does a replacement take?
A standard tank swap takes 2 to 4 hours. A tankless conversion or heat pump install takes 4 to 8 hours depending on gas line, venting, and electrical requirements. We provide exact timing with your quote.
Do you remove and dispose of the old unit?
Yes. Every replacement includes draining the old tank, disconnecting all lines, removing the unit from your home, and proper disposal. You never have to deal with the old water heater yourself.
What size water heater do I need?
For most homes, a 40 gallon tank works for 1 to 2 people, a 50 gallon for 3 to 4 people, and a 75 gallon or tankless for 5 or more. We size the unit based on your household demand, not guesswork.
Should I switch from tank to tankless?
Tankless units cost more upfront but provide endless hot water, use 20 to 30 percent less energy, last nearly twice as long, and free up floor space. We help you weigh the cost and benefits for your specific situation.
What code updates are required?
Current WA code typically requires an expansion tank, seismic strapping, proper T&P discharge routing, updated supply connectors, and correct venting. We include all required code updates in every replacement quote.
Do I need a permit for replacement?
In most jurisdictions across Whatcom and Skagit Counties, a plumbing permit is required for water heater replacement. We handle all permit coordination and scheduling as part of our service.
Can you replace my water heater today?
In many cases, yes. We stock common 40 and 50 gallon tank units and can perform same day replacements for emergency situations. Call us and we will confirm availability for your specific unit size and type.
