A water heater installation is more than setting a new tank where the old one stood. Correct sizing for your household, altitude-rated gas orifice selection, venting that meets Denver's current mechanical code, and proper seismic strapping all affect how well the unit performs and how long it lasts.
We install 40, 50, and 75-gallon gas and electric tank water heaters throughout Sherrelwood, Chaffee Park, and Skyland, with same-day installation available on most weekday appointments when the replacement unit matches your existing fuel type and venting configuration.
Every installation includes removal and haul-away of your old unit, a new expansion tank where required by code, and a permit pulled in your name so the work is documented and inspection-ready.
Signs it's time for a new installation
- Your current unit is leaking from the tank body itself
- You're remodeling and need to relocate or upsize the unit
- Your household has outgrown your current tank's capacity
- You're converting from tank to tankless or to a heat pump unit
- You're building new or finishing a basement with no existing unit
OUR INSTALLATION PROCESS
What happens during this service
Sizing consultation
We calculate the right tank size from your fixture count, household size, and peak usage — not a generic default.
Permit & scheduling
We pull the required Denver mechanical permit and schedule your installation, typically within 1–2 days.
Removal & installation
Your old unit is drained, disconnected, and hauled away; the new unit is set, connected, and strapped to current seismic code.
Altitude & venting check
Gas units are fitted with altitude-rated orifices; venting is verified or upgraded to meet Denver's mechanical code.
Testing & walkthrough
We run a full heat cycle, check for leaks at every fitting, and walk you through the new unit's controls and warranty.
PRICING
What affects installation 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 (gas installations generally cost more than electric due to venting and gas line work)
- Whether existing venting meets current code, or needs to be upgraded
- Whether an expansion tank is required and not already present
- Access to the mechanical closet or basement location
- Any gas line resizing needed for a larger-capacity unit
FAQ
Common questions about this service
How long does a standard installation take?
Most like-for-like tank installations are completed in 2–3 hours. Installations requiring venting upgrades or gas line work can take longer, which we'll flag during your quote.
Do you handle the permit?
Yes, we pull the required Denver mechanical permit and coordinate the inspection as part of the installation.
Can you install the same day I call?
Often yes, for standard tank replacements matching your existing fuel type. Custom sizing, tankless conversions, or venting upgrades may need a day or two of lead time for parts.
What size water heater do I need?
For most 3-bedroom Sherrelwood homes with 2-3 people, 40-50 gallons is standard. We size yours specifically to your fixture count and household during the quote.
