Not the water, mostly. SAWS covers San Antonio and much of Bexar County, so hardness of 15 to 20 grains per gallon is the shared baseline nearly everywhere we work.
What changes is the housing, and that's what moves a quote. The age of the house decides where the water heater sits, what shape the surrounding plumbing is in, and whether the installation meets current code or needs catching up. A tank in an open garage is straightforward. That same tank in a 1960s hallway closet with no drain pan isn't.
Five of our service areas have enough of their own character to warrant a proper page: New Braunfels, Schertz, Cibolo, Converse, and Boerne. The rest are covered below.
Inside Loop 410 — the older core
Alamo Heights, Terrell Hills, Olmos Park, Balcones Heights, Castle Hills, Leon Valley, Windcrest and Kirby.
This is the oldest housing we work in, and the water heaters reflect it. Expect units in interior closets and utility rooms rather than garages, sometimes in spaces that were never designed around servicing an appliance. Many have been replaced once or twice already, occasionally by previous owners and occasionally without a permit.
The recurring theme is the plumbing around the heater rather than the heater itself. You'll find twenty- and thirty-year-old shutoff valves, corroded unions, and supply lines that should've been replaced during the last swap but weren't. A competent replacement here includes new connectors and a new shutoff, and if a quote doesn't mention them, ask why.
Older closet installations often lack a drain pan and drain line too, which current code requires anywhere a leak would damage the building. That's real work at replacement time, not an upsell.
The North Side and Stone Oak
Stone Oak, Shavano Park, Hollywood Park, Timberwood Park, Bulverde and the 1604 corridor.
Newer housing, mostly 1990s through 2010s, and the water heaters here are largely original builder-installed units now reaching the eight-to-twelve-year window where they start to fail.
Two things shape the work here. First, these are usually two-story homes with the heater in a garage or an upstairs closet — and an upstairs install needs a proper pan and drain, because a leak up there doesn't stay up there. It goes through a ceiling. Second, bigger houses often mean two water heaters or one high-capacity unit, which changes both the sizing conversation and what a replacement costs.
Stone Oak sits right at the edge of the Hill Country, and some properties on the outer fringe are on private wells rather than SAWS. It's worth confirming which you're on, because untreated well water is harder on a tank than anything the city delivers.
The Northeast corridor
Universal City, Live Oak, Selma, Converse and the Randolph area.
Steady 1970s-through-1990s suburban stock with plenty of military turnover from Randolph AFB. The practical consequence: water heaters in homes where nobody held the property long enough to build a maintenance history. Nobody flushed it, and the records didn't survive the sale.
Most calls here open with "I don't know how old it is." That's fine — the manufacture date is encoded in the serial number on the rating label, and reading it is the first thing anyone should do.
West and Northwest
Helotes, Fair Oaks Ranch, Alamo Ranch and the far west side.
A mix of established neighborhoods and fast newer development, with lot sizes growing as you head out. Properties on the outer edge are likelier to be on wells or smaller water systems instead of SAWS, and that changes your maintenance interval. Untreated Hill Country groundwater can be considerably harder than the municipal supply, so you're flushing twice a year rather than annually.
Seguin and the east
Seguin, Marion and the Guadalupe County side.
Far enough out that travel is a real factor, and permitting runs through Guadalupe County rather than Bexar. Seguin's got its own older core with housing much like inside-410 San Antonio, plus newer development around the edges. Call to confirm coverage before you assume it.
Permits — same requirement, different desks
A water heater replacement is permitted work everywhere we serve. Your plumber pulls it, and they can only do that where they're properly registered.
| Area | County | Permitting through |
|---|---|---|
| San Antonio, Alamo Heights, Leon Valley | Bexar | City of San Antonio DSD (or the individual city) |
| Converse, Universal City, Live Oak, Selma | Bexar | The individual city |
| Schertz | Guadalupe / Comal / Bexar | City of Schertz |
| Cibolo | Guadalupe | City of Cibolo |
| New Braunfels | Comal (part Guadalupe) | City of New Braunfels |
| Boerne | Kendall | City of Boerne or Kendall County |
| Seguin | Guadalupe | City of Seguin |
The requirements are substantively the same throughout: current code, an expansion tank on a replacement, a correct T&P discharge line, proper venting, and an inspection at the end. What differs is the office. Ask any plumber whether they regularly pull permits in your jurisdiction — the honest ones will tell you when they don't. What the permit involves has the detail.

Questions
Frequently Asked Questions
What areas do you cover for water heater repair?
San Antonio proper plus New Braunfels, Schertz, Cibolo, Converse, Boerne, Universal City, Live Oak, Helotes, Seguin, Selma, Windcrest, Leon Valley, Castle Hills, Alamo Heights, Terrell Hills, Balcones Heights, Kirby, Shavano Park, Hollywood Park, Fair Oaks Ranch, Bulverde and the surrounding communities. If you're at the edge of that, call and we'll tell you honestly whether we can help.
Does the price change depending on which suburb I'm in?
Not much by location, but a lot by house. A 1960s home inside Loop 410 with the heater in an interior closet is a different job from a 2015 Stone Oak house with it in the garage. Metro-wide, most repairs run $298 to $788 and a tank replacement is $2,100 to $2,700 installed.
Do permit rules differ between San Antonio area cities?
The requirement is consistent — a water heater replacement is permitted work and your plumber pulls it. What differs is which office issues it. San Antonio, Converse, Universal City and Live Oak are in Bexar County; Schertz spans three counties; New Braunfels is mostly Comal; Boerne is Kendall; Seguin is Guadalupe. A plumber who works your area knows which desk to use.
Is the water the same everywhere you serve?
Close, but not identical. SAWS supplies San Antonio and much of Bexar County at 15 to 20 grains per gallon. New Braunfels Utilities runs its own system with reported hardness around 13.7 to 17.4. Schertz and Cibolo share a regional supply, Boerne has its own city utility plus many properties on private wells. All of it is well above the 10.5 threshold for very hard water.
Can you help if I'm outside these areas?
Sometimes. Call (210) 767-9170 and we'll tell you straight whether someone covers your address rather than taking your details and hoping. If we can't help, we'll say so.
