Replacement is the right call when a unit is leaking from the tank itself, has failed repeatedly within a short window, or is old enough that a major component failure would cost close to a new unit anyway. Unlike a repair, replacement also brings your installation fully up to Denver's current mechanical code — venting, strapping, and expansion tank requirements included.
We stock common tank sizes and can often complete a straightforward replacement the same day we're on-site for the initial diagnosis, rather than requiring a second scheduled visit.
If you're not sure whether you need replacement or another repair, our technicians will give you both numbers on the same visit — see our guide on 7 signs you need replacement, not repair.
When replacement makes more sense than repair
- The tank itself is leaking, rather than a fitting or valve
- The unit is past 10 years old with a major component failure
- You've had multiple repairs within the past year
- The unit doesn't meet current venting or seismic strapping code
- You want to upgrade capacity, efficiency, or fuel type at the same time
OUR REPLACEMENT PROCESS

Assessment & quote

PRICING
What affects replacement cost
We quote a flat rate on-site before starting any work. These are the main factors that move price up or down for this service in Sherrelwood:
- Tank size and fuel type of the replacement unit
- Whether venting or gas line work is needed to meet current code
- Whether you're switching fuel type or unit type (e.g., tank to tankless) at the same time
- Removal complexity based on the unit's location in your home
FAQ
Common questions about this service
Can you replace my water heater the same day?
Often yes, if a matching tank size and fuel type is in stock and no major venting changes are needed. We'll confirm timing during the on-site assessment.
Do I have to match my old unit's size and fuel type?
No — replacement is a good opportunity to upsize, downsize, or switch to tankless or heat pump if it better fits your household now.
Will replacement bring my setup up to code?
Yes, every replacement includes current venting, strapping, and expansion tank requirements, even if your prior installation predates them.
What happens to my old water heater?
We haul it away for proper disposal as part of the replacement — you don't need to arrange this separately.
