Water Heater Installation & Replacement in Katy, TX
When it no longer pays to repair, we size the right unit for your household, install it to code, and haul the old one away — often the same day.
Why the installation matters as much as the unit
Improper water heater installation can cause a multitude of problems — the heater may underperform and cost you dearly in energy bills, and bad gas or venting work is genuinely dangerous. Choosing the right plumber makes all the difference.
Every installation we do includes correct sizing for your household, new supply line connections, code-compliant venting on gas units, expansion tanks where required, disposal of the old unit, and a post-install test verifying temperature, pressure and flow.
When replacement beats another repair
Water heaters are only designed to last so long — typically 8–12 years for a tank unit. When repair costs exceed 50% of the replacement price, or the unit is past that age, a new water heater is the smarter investment.
We'll walk you through the options — traditional tank, tankless, or hybrid heat pump — assess your household size, hot water demand, gas or electric availability, and budget, and recommend the right system with no pressure to upsell.
What we handle
Water Heater Installation work we handle every week
Traditional Tank (Gas & Electric)
The most common type in Katy homes. We size the tank correctly for your household — 40, 50 or 75 gallon — and install to code, including expansion tanks where required.
Tankless Systems
Endless hot water on demand with 20–30% energy savings over tank units. Ideal for larger families or homes short on space. We install Rinnai, Navien, Noritz and Rheem.
Hybrid Heat Pump Units
The most energy-efficient option available — it pulls heat from the surrounding air. Best suited to garage installations in Katy's warm climate.
Old Unit Removal
Every installation includes proper disconnection and disposal of your old water heater — no unit left in the driveway.
Code-Compliant Venting & Connections
New supply line connections and code-compliant venting on gas units, verified before we leave.
Post-Install Testing
Temperature, pressure and flow are all tested after installation — the job isn't done until the numbers are right.

281-601-1513How much does a new water heater cost in Katy?
A traditional tank unit typically runs $1,200–$2,500 installed; tankless systems run $2,500–$4,500 depending on fuel type and whether gas line or electrical upgrades are needed. We give free, upfront estimates with no hidden fees.
Can you replace my water heater the same day?
Often, yes. If your tank has failed — especially a bottom leak, which can't be repaired — we can usually remove the old unit and install the replacement in a single visit.
What size water heater do I need?
It depends on your household. Tanks come in 40, 50 and 75 gallon sizes; we size for your family's hot water demand rather than defaulting to what's already there. For larger families, a properly sized tankless system often makes more sense.
Do you take away the old unit?
Yes — every installation includes proper disconnection and disposal of your old water heater.
Is a permit required to replace a water heater in Katy?
Water heater work must meet local code — that includes expansion tanks where required and compliant venting on gas units. Our installations are code-compliant and handled by licensed plumbers, so the paperwork side is covered.
