Straight Repair-or-Replace Answers
Know which one you're actually looking at before you decide
Boerne is the one service area where the first question isn't about the heater at all. It's where your water comes from.
Properties inside the City of Boerne's service area get treated municipal water from the city's own utility. Properties on acreage outside it — and there are many, this being the Hill Country — are frequently on private wells.
That distinction drives everything else. A municipal supply is treated, monitored, and reported on annually. A private well delivers exactly what the aquifer holds, with no treatment unless you installed it yourself. In limestone country, that routinely means hardness well beyond anything a city system would deliver, and sometimes iron or sulfur alongside it.
So two houses a mile apart in Boerne can have completely different water heater lifespans, for reasons that have nothing to do with the heater.
What well water does to a tank
If you're on a well here, the failure pattern is the same as the rest of the region but accelerated.
Scale builds faster on the tank floor and on electric elements, because there's more dissolved mineral arriving and nothing upstream removing it. The anode rod — the sacrificial magnesium or aluminum rod that corrodes so your tank's steel doesn't — gets consumed faster. Once it's gone, the tank itself becomes the sacrificial metal, and that's the failure nobody can repair.
Iron content, where present, adds discoloration and its own deposits. Sulfur produces the rotten-egg smell in hot water that people usually blame on the heater when it's actually a reaction between sulfate-reducing bacteria and a standard magnesium anode. That one has a genuinely satisfying fix: switching to an aluminum-zinc anode usually resolves it without touching anything else.
Practical guidance for well properties: flush twice a year rather than annually, have the anode checked around year four rather than year six, and if you're already running a softener or filtration, keep it maintained — the water heater is downstream of every decision you make about treatment. The underlying chemistry is on the hard water page.
Kendall County, not Bexar
Boerne sits in Kendall County, entirely outside Bexar. Permitting runs through the City of Boerne for properties inside the city limits, and through county requirements for those outside.
Substantively the code expectations don't change — a replacement needs current-code compliance, an expansion tank on a closed system, a correct T&P discharge line, proper venting, and an inspection. What changes is the office, the process, and sometimes the timeline.
The question worth asking any plumber quoting a Boerne job: do you pull permits in Kendall County regularly? A San Antonio plumber who works almost entirely inside Loop 1604 may not, and that's how jobs end up unpermitted — not through malice, but because the permitting office is unfamiliar and the homeowner never asked. What the permit involves covers the general rules.
Boerne has also grown quickly — from 17,865 in 2020 to 24,047 by 2025 — so a substantial share of local housing is new enough that original water heaters are only now reaching the age where they fail.

Questions
Frequently Asked Questions
Do you cover Boerne?
Yes. Boerne is a regular service area — the Census put it at 24,047 in 2025, growing fast from 17,865 in 2020. Call (210) 767-9170 for a free estimate from one licensed local plumber.
Is Boerne on city water or well water?
Both, depending on where you are. The City of Boerne runs its own utility for properties inside the service area, while many homes on acreage outside it are on private wells. That distinction matters more for a water heater here than anywhere else we serve, because untreated well water in this geology can be considerably harder than any municipal supply.
Does well water damage water heaters faster?
It can, significantly. Municipal supplies are treated and monitored; a private well delivers whatever the aquifer holds. In Hill Country limestone that often means very high hardness, sometimes with iron or sulfur as well. Homes on wells here should treat flushing as a twice-yearly job and expect to check the anode rod more often than a city-water house.
Who permits a water heater replacement in Boerne?
Boerne is in Kendall County, outside Bexar entirely, and permitting runs through the City of Boerne for properties inside the city. County properties follow county requirements. Either way it's not San Antonio's Development Services — ask any plumber whether they regularly pull permits in Kendall County.
