Water Softeners in Boerne, TX
Kendall County · City of Boerne water / private wellsBoerne runs two kinds of water, and they need two different answers.
Inside city limits you are on Boerne city water — hard, but a straight water softener job. Out toward Fair Oaks, Comfort, and the ranch lots you are on a Trinity well, and iron or sulfur is usually part of the picture. Tell us which on the call.

What comes out of the tap in Boerne
Boerne is not on SAWS. Kendall County sits outside SAWS’s service counties entirely, and inside the city limits your water comes from City of Boerne Utilities. The city’s own 2025 water quality report puts hardness at 321.6 mg/L on average, in a range of 203 to 382 — about 18.8 grains per gallon, somewhere between 12 and 22 depending on the day.
The city says itself that a single consistent number is hard to give, because the supply is a blend that shifts: roughly a fifth to a quarter Trinity aquifer groundwater, the rest surface water from Canyon Lake through GBRA and from Boerne City Lake. That swing is why we size to the household rather than to one number. At 12 grains a water softener regenerates less often; at 22 it works harder. Either way it is hard water, and the scale on fixtures, the film on glass and the shortened life of a water heater are what people in Boerne call about.
Outside the city limits — toward Fair Oaks Ranch, Comfort, and the ranch lots off I-10 and Highway 46 — you are on Texas Water Company supply or a private Trinity well. The wells are where iron staining and the sulfur smell at the hot tap show up, and a water softener on its own will not survive them. That is a two-stage job: iron and sulfur media first, softener second.
Kendall County fits Jason's rule of thumb for the counties around Bexar: municipal water means hardness and possible iron, a well means hardness, iron and possible hydrogen sulfide, and the small community water supplies serving some developments are chlorinated, TCEQ-regulated public systems that in his experience still run harder and more iron-prone than city water.
Hardness figures are the City of Boerne’s, from its 2025 Consumer Confidence Report and water quality page, not measurements we took. We test your tap free before we size anything.

What that means for the install
In-town Boerne homes built in the last twenty years are usually pre-plumbed — loop in the garage, about an hour's install, inside the published range. The LPWS48K is the common pick, because Boerne households tend to run larger and the water tends toward the top of the city's range. Older homes around Main Street and the Hill Country Mile often have no loop; text us the three photos and we quote it anyway.
Well homes get a free test for hardness, iron and chlorine first. If the iron is above the staining threshold or there is sulfur at the hot tap, the iron filter goes in ahead of the water softener, and the job lands in the $2,500–$4,500 range the well water page describes. Same warranty either way: five years on the valve, ten on the tank, one year of free service checkup.
Published range $2,100–$4,000 pre-plumbed, softener only. Higher only for code work, distance, or special circumstances.
No trip charge to Boerne.
No trip charge to Boerne. I-10 west is a regular run for us, and Fair Oaks Ranch and Comfort are on the same trip. Mon–Sat 7am–5pm, quoted over the phone first.
Water softener questions we get from Boerne
Is Boerne water hard?
Yes. On the city’s own 2025 numbers it averages about 18.8 grains per gallon and ranges from 12 to 22, because the supply is a blend of Trinity groundwater and Canyon Lake surface water that shifts through the year.
I am outside Boerne city limits on a well. What do I need?
A free test first — hardness, iron, chlorine. Kendall County wells commonly show iron staining and sulfur at the hot tap, and those get their own filter ahead of the water softener. Most well jobs run $2,500–$4,500.
Do you charge extra to come to Boerne?
No trip charge to Boerne, Fair Oaks Ranch or Comfort. The far ranch lots we price on the call — distance is one of the three things that can push a job above the published range, and we tell you on the phone, not on the invoice.
Do you repair water softeners already installed in Boerne?
Yes, any brand, $100 to $1,000 depending on what is wrong, and we say when it is not worth fixing. A photo of the control head and the brand label is usually enough to quote the visit.
Same water softener, same warranty, everywhere we go.
10% cross-link resin, Clack valve. Five years on the valve, ten on the tank, one year of free service checkup. Installed by Jason, Estella and Anthony.
If you are on a well out here, this is how we handle iron and sulfur ahead of the softener. It is the same job we do across Bulverde and Spring Branch.
