Water Heater Replacement
Tank replacement sized to the house, with the old unit hauled off.
Quick answer
We replace tank water heaters sized to the house and haul the old unit off, across the Bradley–McMinn corridor and greater Chattanooga. Tennessee license #5045.
A water heater replacement is the job where getting the gas, venting, and connections right matters most. We size the tank to how the house actually uses hot water, fit it properly, and take the old one with us.
A replacement is the job people most often get sold wrong, because the easy version is to pull the old tank and drop in whatever is on the truck. Done that way it usually works, and it usually costs you either capacity you needed or money you did not.
We treat it as a real install: the right size for how your household actually uses hot water, the gas and venting connected to code, the expansion tank and safety pieces the code calls for, and the old unit hauled off.
What the job covers
- Tank replacement sized to the household, not just swapped like-for-like
- Correct gas, water, and venting connections to code
- Expansion tank and code upgrades where required
- Haul-off and disposal of the old unit
- The old unit hauled away as part of the job
Before and after
Water heater replacement — the same job, both ends.
Before
AfterHow to tell
Signs you need water heater replacement
- The tank is leaking from its body, not a fitting — this one is not repairable
- The unit is past about ten to twelve years old
- Persistent rusty water even after the lines run clear
- You are on the second or third repair in a short span
- It can no longer keep up with the household’s hot-water demand
- Heavy rumbling from years of sediment that flushing no longer fixes
Sizing it to the house, not the box it came in
The right size is set by how many people draw hot water at the same time, not by square footage or by matching whatever number was on the old tank. An undersized unit leaves you cold at the end of a morning; an oversized one costs more to buy and to keep hot.
We size it to real use, and we will tell you honestly if your existing tank was the wrong size all along. Getting this right is most of the value of doing a replacement properly.
How we work
How we handle water heater replacement
Size it to your household
Match the tank to real simultaneous demand, not the number on the old one.
Install to code
Gas, water, and venting done right, plus the expansion tank and safety pieces the code requires.
Haul the old one off
The old tank leaves with us — disposal is part of the job.
Talk about longevity
If hard water shortened the last one, we cover what would make this one last.
Permits
Some plumbing work requires a permit and an inspection, and some does not. Whether one is required for your job is determined by the Authority Having Jurisdiction — the city or county building and codes office for your address — and it is at their discretion.
Usually requires a permit
- Water heater replacement and tankless conversion
- Whole-house repiping
- Water service line and sewer line replacement
- Gas line installation and repair
- Relocating a fixture to a new position
Usually does not
- Drain cleaning and clearing blockages
- Emergency and repair work
- Like-for-like fixture replacement
- Water heater repair
- Camera inspection and diagnostics
This is general guidance rather than a ruling, and it can differ from one town to the next. The Authority Having Jurisdiction makes the determination. Across the Bradley–McMinn corridor we pull the permit and book the inspection ourselves. Inside Hamilton County and Chattanooga the permit office does not accept an application from our license class, so permit-required jobs there are referred to a licensed partner who does the work and meets the inspector.
