A water heater install isn't just swapping a tank — it's sizing, venting, gas line capacity, code compliance, and a clean job that will pass inspection and run safely for the next decade. BF Plumbing & Drain installs gas, electric and tankless water heaters across North Atlanta with same- or next-day availability for most sizes, and we haul the old unit away as part of the job.
We carry major brands and we'll match the unit to your house, not the other way around. Family size, peak demand, fuel cost, available space, and whether you want to convert to tankless all play into picking the right unit. We give you a written quote with the unit model, scope and warranty before any work starts.
When it's time to replace, not repair
A few clear signals that the tank's days are numbered:
- Unit is 10+ years old and starting to show problems.
- Visible rust on the tank exterior or rusty hot water.
- Active leak from the tank itself (not just the T&P or drain valve).
- Running out of hot water faster than it used to — capacity loss from sediment.
- Repair cost is more than one-third of replacement cost.
- You're remodeling and want to upsize, relocate or convert to tankless.
Our water heater installation process
A proper install follows code and protects your warranty. Our sequence:
- 1
Sizing & quote
We size the unit to peak hot-water demand and recovery rate, not just the gallon number on the old tag. You get a written quote with the model, scope and warranty terms.
- 2
Permit & code review
Many counties require a plumbing permit and inspection for water heater installs. We pull it. We also check expansion tank, T&P discharge, sediment trap, vent clearances, and drip-pan requirements against current code.
- 3
Removal & haul-away
We drain and disconnect the old unit, cap the gas safely, and remove it. No old tank left in your driveway.
- 4
Install & connect
New unit set, leveled, gas or electric reconnected, water lines connected with new flex connectors or hard-piped, T&P discharge to code, expansion tank verified or added, drip pan if required.
- 5
Start-up, test & inspection
Bleed air, light gas or energize elements, verify temperature and recovery, leak-check every connection, schedule the city inspection. Your 1-year workmanship warranty starts here.
What water heater installation costs in North Atlanta
Install pricing depends on the unit, the location, and what brings the system up to current code:
- Unit type and capacity — 40-gal gas tank vs. 75-gal high-recovery vs. tankless.
- Fuel type and any conversion (electric to gas, tank to tankless).
- Code upgrades — expansion tank, drip pan, sediment trap, T&P discharge, seismic strapping where required.
- Location — attic and crawlspace installs cost more than a garage swap.
- Permit and inspection fees by county.
- Brand and warranty tier selected.
What works best in North Atlanta homes
North Atlanta is a patchwork of housing stock and soil conditions, and that drives a lot of plumbing decisions. Subdivisions built in the 1990s and early 2000s across Canton, Woodstock and Holly Springs typically run builder-grade PVC and CPVC that's now reaching end-of-life on fittings and shutoffs. Older homes in Marietta, Roswell and Kennesaw still have cast-iron drains and copper supply that scale up and pinhole. Newer construction in Acworth, Ball Ground and Cumming sits on red clay that shifts seasonally and stresses underground lines.
We work in this market every day, so we know which neighborhoods have shared sewer easements, which water utilities require a permit pull, and which inspectors want to see specific fittings. That local knowledge shortens the job and keeps it code-correct the first time.

Frequently asked questions
How long does an install take?
A like-for-like tank swap is usually 2–4 hours. A tankless conversion is typically 6–10 hours including gas line and venting. A fuel conversion is a 1-day job.
What size do I need?
Family of 2–3: 40-gallon gas or 50-gallon electric. Family of 4–5: 50-gallon gas or 65–80 gallon electric, or a properly sized tankless. We size to peak demand, not just headcount.
Tankless or tank — which is better?
Tankless wins on lifespan (20+ years), endless hot water, and energy bills. Tank wins on upfront cost and simpler installs. Most North Atlanta homes can go either way; we'll explain the trade-offs for your specific setup.
Do you haul away the old unit?
Yes. Standard with every install.
