Short answer: Boerne sits over the Trinity and Edwards aquifers, and water moving through that limestone arrives hard. Whether you are on the city system or one of the many private wells around Kendall County changes what treatment belongs on your wall.

Why Boerne water is hard
Rain here falls on limestone and dissolves calcium and magnesium on its way down. Those two minerals are what we measure as hardness.
Readings across Boerne commonly sit in double digits in grains per gallon, which every published scale calls very hard.
The City of Boerne treats and reports its water, and it is safe to drink. Treatment addresses safety rather than hardness, so it reaches your tap unchanged.

City supply and Kendall County wells
Inside the city limits most homes are on the municipal system, which is monitored, tested and published.
Outside them, across a great deal of Kendall County, households draw from private wells that nobody samples and nobody reports on.
Those are different starting points, so we test at the address rather than quoting from a postcode.
What hardness is costing a Boerne household
Scale on a water heater element insulates it, so the unit burns more energy for the same hot water, month after month.
Soap, shampoo and detergent go further in soft water because none of the product is consumed reacting with calcium.
Appliance failures arrive as valves and heating elements rather than as hardness, which is why the underlying cause often goes unaddressed for years.

What Boerne area wells commonly carry
Iron shows as orange staining in basins and on laundry and, more expensively, fouls softener resin if it reaches it untreated.
Hydrogen sulfide is less common but unmistakable, producing the rotten egg smell. It is a dissolved gas, so a softener does nothing to it.
Sediment spikes after heavy rain, particularly in shallower formations and near Cibolo Creek.
| Boerne supply | Common issue | What we fit |
|---|---|---|
| City water | Hardness in double digits | Correctly sized ion-exchange softener |
| City water | Chlorine taste | Whole-house carbon filtration |
| City water | Taste at the kitchen tap | Under-sink reverse osmosis |
| Private well | Orange staining | Iron filter ahead of the softener |
| Private well | Rotten egg odour | Aeration or catalytic carbon |
| Private well | Cloudy after rain | Spin-down plus cartridge filtration |
The order that makes a system last
On a well the sequence is fixed: sediment, then iron and sulfur, then softening, then disinfection where bacteria are present.
Each stage protects the next. Putting a softener ahead of iron removal is the most expensive mistake in well treatment, and it is the one we correct most often.
Sizing a system for your household
Capacity is arithmetic rather than opinion: household size, daily consumption and measured grains per gallon give the daily load.
The unit is then chosen to regenerate every three to five days. Undersized systems regenerate constantly and waste salt; oversized ones cost more than the house needs.
Larger properties on the edges of Boerne often run long pipe runs and multiple bathrooms, which changes both the sizing and where the equipment belongs.
Drinking water at the kitchen tap
Softening deals with scale. It does not change taste, and some households want a further stage for what they drink and cook with.
Reverse osmosis under the sink is the usual answer, and behind a working softener a membrane lasts for years.
Not every home needs it. Where the water is already clean we say so rather than selling a stage that adds nothing.
Servicing what you already have
A lot of equipment around Boerne was fitted by companies that have since closed, leaving owners with no service history and no support.
We service every major brand, including systems we did not install, and we begin by testing rather than assuming the original specification was right.
Where a repair genuinely beats a replacement we say so, and we carry common parts so most calls finish the same day.
Where we work
We cover Boerne and the wider Kendall County area, along with Comfort, Fair Oaks Ranch, Bulverde, Kerrville and San Antonio.
Emergency callout runs around the clock, because a leaking or bypassed system is a today problem.
Testing is free and carries no obligation, and a fair share of visits end with us recommending nothing at all.
Frequently asked questions
Is Boerne water hard?
Yes. Readings commonly sit in double digits in grains per gallon, which is classed as very hard.
The city treats the water. Why do I still need a softener?
Municipal treatment in Boerne makes water safe rather than soft, so hardness arrives at the tap unchanged.
We are on a well in Kendall County. Where do we start?
With a free test. Private wells are unregulated, so nothing has been checked unless you arranged it yourself.
Do I need reverse osmosis as well as a softener?
Only if you want the taste changed. Softening handles scale; reverse osmosis polishes what you drink and cook with.
Will you service a system another company installed?
Yes, on every major brand, starting with a water test rather than an assumption.
