What's included

What your gas water heater installation covers

Full system evaluation. We assess your gas connection, install location, and venting situation before we quote. No assumptions — your estimate reflects what your home actually needs.

Licensed plumbers, code-compliant work. Our technicians handle gas line setup, venting, drainage, and pressure relief. Local permits and inspections are part of our process, not an afterthought.

Brand selection from leading manufacturers. We carry Rheem, Rinnai, Lochinvar, and others. We recommend the unit that fits your household's hot water demand and your home's layout — not whatever's easiest to upsell.

How it works

What a gas water heater installation actually involves

Installation

A clean swap, handled by licensed plumbers

It is more than swapping a tank. Our licensed plumbers disconnect and remove the old unit, set the new one in place, extend or modify the gas line if needed, update flue pipes or chimney liners for proper exhaust venting, pull required permits, and verify drainage, temperature control, and pressure relief before leaving — most standard replacements finish in a single day.

  • Gas line work is done safely and to code, including extensions if no connection exists at the install location
  • Permits and inspections for gas and plumbing are handled for you
  • Drainage, pressure relief, and temperature control are verified before we leave
Equipment selection

Choosing the right unit for your home

The right choice depends on your household, not whatever is on the truck. We size the system to your real hot water demand and walk you through the three venting options — power vent (fan-driven horizontal exhaust), direct vent (outside air, wall discharge), and natural draft (vertical chimney) — explaining recovery rate and efficiency tradeoffs so the unit matches your space and the way your home is built.

  • System sized to your real hot water demand, not a rule of thumb
  • Three venting types explained — power vent, direct vent, natural draft
  • Recovery rate and efficiency tradeoffs covered before you decide
What to expect

A clear estimate, a code-compliant install, and support that lasts

Typical cost $5,500–$10,000

Most gas water heater projects fall in this range, with a typical install around $7,500. Your itemized estimate reflects gas line setup, venting system, tank capacity, and permit compliance — no surprise add-ons.

Code-compliant install Safe, inspected, done right

Our licensed plumbers and technicians disconnect the old unit, handle the gas line work and venting setup, and verify drainage, temperature control, and pressure relief against code-required inspections before they leave.

Long-term support Hot water you can count on

Your new unit is covered by manufacturer warranties, and our optional maintenance plans keep it clean and efficient. We support the system long after the install is done.

The guys were very informative and polite. They went through the house in a couple of hours and did a great job. They gave me other tips about my furnace as well.

Very good audit & weather stripping, the only thing they forgot was turning the furnace back on
