Hard Water Solutions for the Texas Hill Country & Highland Lakes
The Hill Country has some of the hardest water in Texas, commonly 15 to 20+ grains per gallon, roughly double what Houston sees. Lantz Home Services tests your water, then installs the right water softener or whole-home filtration system to stop scale, protect your appliances, and end the soap-scum fight. Family-owned and serving the Highland Lakes since 1972.
Why is Hill Country water so hard?
Hill Country water is hard because the region sits on the limestone Edwards-Trinity Plateau Aquifer.
As rainwater filters through limestone, it dissolves calcium and magnesium, the two minerals that make water "hard." By the time that water reaches your tap, it carries a heavy mineral load. Local hardness commonly runs 15–20+ grains per gallon, and anything above 7 grains per gallon is already classified as hard water.Because the Highland Lakes area mixes municipal supply and private wells, no two homes are identical. A house on city water in Lago Vista and a well-fed home outside Marble Falls can test very differently, which is exactly why we test before we recommend anything.
Signs you have a hard water problem
Most Hill Country homeowners notice hard water long before they name it. Common signs include:
- White, chalky scale on faucets, showerheads, and glass
- Soap and shampoo that won't lather, plus stubborn soap scum
- Spotty dishes straight out of the dishwasher
- Dry, itchy skin and dull hair after showering
- Stiff, faded laundry that needs more detergent
- A water heater that runs out faster or fails years early from scale buildup
Hard water is safe to drink — the problem is what it does to your home.
Scale buildup shortens the life of water heaters, dishwashers, and washing machines, drives up energy bills, and wastes soap and detergent. Treating it protects equipment you've already paid for.Your hard water treatment options
Whole-home water softeners
A traditional ion-exchange water softener is the proven fix for scale. Installed at your home's point of entry, it swaps the calcium and magnesium that cause hardness for sodium (or potassium, if you prefer lower sodium), treating every tap, shower, and appliance in the house. For our hardness levels, this is the workhorse solution.
Salt-free water conditioners
Salt-free conditioners don't remove minerals; they alter their structure to reduce scale sticking to surfaces. They use no salt and waste no water on regeneration, which appeals to some homeowners, but they don't technically "soften" water. We'll be straight with you about the tradeoffs for your specific hardness level.
Whole-home filtration & reverse osmosis
Softening handles scale, but filtration handles the rest — chlorine, sediment, taste, and clarity. Many Hill Country homes pair a softener with whole-home filtration, and add a reverse-osmosis system at the kitchen sink for drinking and cooking water. Well-water homes especially benefit from added sediment and iron treatment.
| If your main concern is… | The right starting point |
|---|---|
| Scale, soap scum, appliance protection | Water softener |
| No-salt option, lighter scale reduction | Salt-free conditioner |
| Taste, chlorine, sediment | Whole-home filtration |
| Clean drinking & cooking water | Reverse osmosis at the sink |
| Well water (hardness + iron/sediment) | Custom multi-stage system |
Why Hill Country homeowners call Lantz
We've worked on Highland Lakes plumbing for more than 50 years, which means we know our water — and the homes built around it. We don't sell one system to everyone.
- We test first. A professional water test tells us your exact hardness, plus iron, pH, and sediment, so the system is sized correctly. An undersized softener regenerates too often and wastes salt; an oversized one runs inefficiently.
- Upfront pricing. You see the full cost before any work begins — no surprises.
- Well & city water experience. From lakeside municipal connections to deep rural wells, we've treated both across the Highland Lakes.
- Local, licensed, and accountable. A real local company you can call back, not a one-truck installer who disappears after the sale.

Hard Water FAQ
Is Hill Country water hard?
Yes — it's among the hardest in Texas.
Because the region sits on the limestone Edwards-Trinity Plateau Aquifer, hardness commonly reaches 15 to 20+ grains per gallon, roughly double the levels in cities like Houston. Anything above 7 grains per gallon is considered hard.
Is hard water dangerous to drink?
No. Hard water is safe to drink.
The calcium and magnesium that cause hardness are naturally occurring and pose no health risk. The problems are practical: scale buildup, soap scum, spotty dishes, dry skin, and shorter appliance life.
What's the difference between a water softener and a water filter?
A softener removes hardness minerals; a filter targets taste, chlorine, and sediment.
A water softener uses ion exchange to remove the calcium and magnesium that cause scale. Whole-home filtration handles other water-quality issues. Many Hill Country homes use both.
How much does a water softener cost in the Hill Country?
It depends on system size, your hardness level, and well vs. city water.
We test your water first, then give you upfront pricing before any work begins, so you know the full cost before you commit.
Does well water need different treatment than city water?
Often, yes — wells frequently test even harder.
Private wells draw straight from the aquifer and may also carry iron and sediment. Because well water isn't municipally regulated after installation, a professional test is the only way to size the right system.
